1 <h1>Perltidy Change Log</h1>
5 <pre><code>- Fix rt #145095, undef warning in Perl before 5.12. Version 20221112 is
6 identical to 2022111 except for this fix for older versions of Perl.
8 - No significant bugs have been found since the last release to CPAN.
9 Several minor issues have been fixed, and some new parameters have been
12 - Fixed rare problem with irregular indentation involving --cuddled-else,
13 usually also with the combination -xci and -lp. Reported in rt #144979.
15 - Add option --weld-fat-comma (-wfc) for issue git #108. When -wfc
16 is set, along with -wn, perltidy is allowed to weld an opening paren
17 to an inner opening container when they are separated by a hash key
18 and fat comma (=>). For example:
22 method_name_foo => {
24 some_other_arg3 => $bar->{'baz'},
29 elf->call_method( method_name_foo => {
31 some_other_arg3 => $bar->{'baz'},
34 This flag is off by default.
36 - Fix issue git #106. This fixes some edge cases of formatting with the
37 combination -xlp -pt=2, mainly for two-line lists with short function
38 names. One indentation space is removed to improve alignment:
40 # OLD: perltidy -xlp -pt=2
41 is($module->VERSION, $expected,
42 "$main_module->VERSION matches $module->VERSION ($expected)");
44 # NEW: perltidy -xlp -pt=2
45 is($module->VERSION, $expected,
46 "$main_module->VERSION matches $module->VERSION ($expected)");
48 - Fix for issue git #105, incorrect formatting with 5.36 experimental
51 - Fix for issue git #103. For parameter -b, or --backup-and-modify-in-place,
52 the default backup method has been changed to preserve the inode value
53 of the file being formatted. If this causes a problem, the previous
54 method is available and can be used by setting -backup-mode='move', or
55 -bm='move'. The new default corresponds to -bm='copy'. The difference
56 between the two methods is as follows. For the older method,
57 -bm='move', the input file was moved to the backup, and a new file was
58 created for the formatted output. This caused the inode to change. For
59 the new default method, -bm='copy', the input is copied to the backup
60 and then the input file is reopened and rewritten. This preserves the
61 file inode. Tests have not produced any problems with this change, but
62 before using the --backup-and-modify-in-place parameter please verify
63 that it works correctly in your environment and operating system. The
64 initial update for this had an error which was caught and fixed
67 - Fix undefined value message when perltidy -D is used (git #104)
69 - Fixed an inconsistency in html colors near pointers when -html is used.
70 Previously, a '->' at the end of a line got the 'punctuation color', black
71 by default but a '->' before an identifier got the color of the following
72 identifier. Now all pointers get the same color, which is black by default.
73 Also, previously a word following a '->' was given the color of a bareword,
74 black by default, but now it is given the color of an identifier.
76 - Fixed incorrect indentation of any function named 'err'. This was
77 due to some old code from when "use feature 'err'" was valid.
80 my ($curr) = current();
84 my ($curr) = current();
87 - Added parameter --delete-repeated-commas (-drc) to delete repeated
88 commas. This is off by default. For example, given:
90 ignoreSpec( $file, "file",, \%spec, \%Rspec );
93 ignoreSpec( $file, "file", \%spec, \%Rspec );
95 - Add continuation indentation to long C-style 'for' terms; i.e.
102 && $array->[$j] gt $array->[ $j + $shell ] ;
111 && $array->[$j] gt $array->[ $j + $shell ] ;
115 This will change some existing formatting with very long 'for' terms.
117 - The following new parameters are available for manipulating
118 trailing commas of lists. They are described in the manual.
120 --want-trailing-commas=s, -wtc=s
121 --add-trailing-commas, -atc
122 --delete-trailing-commas, -dtc
123 --delete-weld-interfering-commas, -dwic
125 - Files with errors due to missing, extra or misplaced parens, braces,
126 or square brackets are now written back out verbatim, without any
127 attempt at formatting.
129 - This version runs 10 to 15 percent faster than the previous
130 release on large files due to optimizations made with the help of
133 - This version was stress-tested for over 200 cpu hours with random
134 input parameters. No failures to converge, internal fault checks,
135 undefined variable references or other irregularities were seen.
140 <pre><code>- No significant bugs have been found since the last release but users
141 of programs which call the Perl::Tidy module should note the first
142 item below, which changes a default setting. The main change to
143 existing formatting is the second item below, which adds vertical
144 alignment to 'use' statements.
146 - The flag --encode-output-strings, or -eos, is now set 'on' by default.
147 This has no effect on the use of the 'perltidy' binary script, but could
148 change the behavior of some programs which use the Perl::Tidy module on
149 files encoded in UTF-8. If any problems are noticed, an emergency fix
150 can be made by reverting to the old default by setting -neos. For
151 an explanation of why this change needs to be made see:
153 https://github.com/perltidy/perltidy/issues/92
155 https://github.com/perltidy/perltidy/blob/master/docs/eos_flag.md
157 - Added vertical alignment for qw quotes and empty parens in 'use'
158 statements (see issue #git 93). This new alignment is 'on' by default
159 and will change formatting as shown below. If this is not wanted it can
160 be turned off with the parameter -vxl='q' (--valign-exclusion-list='q').
162 # old default, or -vxl='q'
163 use Getopt::Long qw(GetOptions);
164 use Fcntl qw(O_RDONLY O_WRONLY O_EXCL O_CREAT);
165 use Symbol qw(gensym);
169 use Getopt::Long qw(GetOptions);
170 use Fcntl qw(O_RDONLY O_WRONLY O_EXCL O_CREAT);
171 use Symbol qw(gensym);
174 - The parameter -kbb (--keep-break-before) now ignores a request to break
175 before an opening token, such as '('. Likewise, -kba (--keep-break-after)
176 now ignores a request to break after a closing token, such as ')'. This
177 change was made to avoid a rare instability discovered in random testing.
179 - Previously, if a -dsc command was used to delete all side comments,
180 then any special side comments for controlling non-indenting braces got
181 deleted too. Now, these control side comments are retained when -dsc is
182 set unless a -nnib (--nonon-indenting-braces) flag is also set to
185 - This version runs about 10 percent faster on large files than the previous
186 release due to optimizations made with the help of Devel::NYTProf. Much
187 of the gain came from faster processing of blank tokens and comments.
189 - This version of perltidy was stress-tested for many cpu hours with
190 random input parameters. No failures to converge, internal fault checks,
191 undefined variable references or other irregularities were seen.
196 <pre><code>- A new flag, --encode-output-strings, or -eos, has been added to resolve
197 issue git #83. This issue involves the interface between Perl::Tidy and
198 calling programs, and Code::TidyAll (tidyall) in particular. The problem
199 is that perltidy by default returns decoded character strings, but
200 tidyall expects encoded strings. This flag provides a fix for that.
202 So, tidyall users who process encoded (utf8) files should update to this
203 version of Perl::Tidy and use -eos for tidyall. For further info see:
205 https://github.com/houseabsolute/perl-code-tidyall/issues/84, and
206 https://github.com/perltidy/perltidy/issues/83
208 If there are other applications having utf8 problems at the interface
209 with Perl::Tidy, this flag probably may need to be set.
211 - The default value of the new flag, --encode-output-strings, -eos, is currently
212 -neos BUT THIS MAY CHANGE in a future release because the current
213 default is inconvenient. So authors of programs which receive character
214 strings back from Perl::Tidy should set this flag, if necessary,
215 to avoid any problems when the default changes. For more information see the
216 above links and the Perl::Tidy man pages for example coding.
218 - The possible values of the string 's' for the flag '--character-encoding=s'
219 have been limited to 'utf8' (or UTF-8), 'none', or 'guess'. Previously an
220 arbitrary encoding could also be specified, but as a result of discussions
221 regarding git #83 it became clear that this could cause trouble
222 since the output encoding was still restricted to UTF-8. Users
223 who need to work in other encodings can write a short program calling
224 Perl::Tidy with pre- and post-processing to handle encoding/decoding.
226 - A new flag --break-after-labels=i, or -bal=i, was added for git #86. This
227 controls line breaks after labels, to provide a uniform style, as follows:
229 -bal=0 follows the input line breaks [DEFAULT]
230 -bal=1 always break after a label
231 -bal=2 never break after a label
246 - Fix issue git #82, an error handling something like ${bareword} in a
247 possible indirect object location. Perl allows this, now perltidy does too.
249 - The flags -kbb=s or --keep-old-breakpoints-before=s, and its counterpart
250 -kba=s or --keep-old-breakpoints-after=s have expanded functionality
251 for the container tokens: { [ ( } ] ). The updated man pages have
254 - Two new flags have been added to provide finer vertical alignment control,
255 --valign-exclusion-list=s (-vxl=s) and --valign-inclusion-list=s (-vil=s).
256 This has been requested several times, most recently in git #79, and it
257 finally got done. For example, -vil='=>' means just align on '=>'.
259 - A new flag -gal=s, --grep-alias-list=s, has been added as suggested in
260 git #77. This allows code blocks passed to list operator functions to
261 be formatted in the same way as a code block passed to grep, map, or sort.
262 By default, the following list operators in List::Util are included:
264 all any first none notall reduce reductions
266 They can be changed with the flag -gaxl=s, -grep-alias-exclusion-list=s
268 - A new flag -xlp has been added which can be set to avoid most of the
269 limitations of the -lp flag regarding side comments, blank lines, and
270 code blocks. See the man pages for more info. This fixes git #64 and git #74.
271 The older -lp flag still works.
273 - A new flag -lpil=s, --line-up-parentheses-inclusion-list=s, has been added
274 as an alternative to -lpxl=s, --line-up-parentheses-exclusion-list=s.
275 It supplies equivalent information but is much easier to describe and use.
276 It works for both the older -lp version and the newer -xlp.
278 - The coding for the older -lp flag has been updated to avoid some problems
279 and limitations. The new coding allows the -lp indentation style to
280 mix smoothly with the standard indentation in a single file. Some problems
281 where -lp and -xci flags were not working well together have been fixed, such
282 as happened in issue rt140025. As a result of these updates some minor
283 changes in existing code using the -lp style may occur.
285 - This version of perltidy was stress-tested for many cpu hours with
286 random input parameters. No failures to converge, internal fault checks,
287 undefined variable references or other irregularities were seen.
289 - Numerous minor fixes have been made, mostly very rare formatting
290 instabilities found in random testing.
295 <pre><code>- No significant bugs have been found since the last release, but several
296 minor issues have been fixed. Vertical alignment has been improved for
297 lists of call args which are not contained within parens (next item).
299 - Vertical alignment of function calls without parens has been improved with
300 the goal of making vertical alignment essentially the same with or
301 without parens around the call args. Some examples:
304 mkTextConfig $c, $x, $y, -anchor => 'se', $color;
305 mkTextConfig $c, $x + 30, $y, -anchor => 's', $color;
306 mkTextConfig $c, $x + 60, $y, -anchor => 'sw', $color;
307 mkTextConfig $c, $x, $y + 30, -anchor => 'e', $color;
310 mkTextConfig $c, $x, $y, -anchor => 'se', $color;
311 mkTextConfig $c, $x + 30, $y, -anchor => 's', $color;
312 mkTextConfig $c, $x + 60, $y, -anchor => 'sw', $color;
313 mkTextConfig $c, $x, $y + 30, -anchor => 'e', $color;
316 is id_2obj($id), undef, "unregistered object not retrieved";
317 is scalar keys %$ob_reg, 0, "object registry empty";
318 is register($obj), $obj, "object returned by register";
319 is scalar keys %$ob_reg, 1, "object registry nonempty";
320 is id_2obj($id), $obj, "registered object retrieved";
323 is id_2obj($id), undef, "unregistered object not retrieved";
324 is scalar keys %$ob_reg, 0, "object registry empty";
325 is register($obj), $obj, "object returned by register";
326 is scalar keys %$ob_reg, 1, "object registry nonempty";
327 is id_2obj($id), $obj, "registered object retrieved";
329 This will cause some changes in alignment, hopefully for the better,
330 particularly in test code which often uses numerous parenless function
331 calls with functions like 'ok', 'is', 'is_deeply', ....
333 - Two new parameters were added to control the block types to which the
334 -bl (--opening-brace-on-new-line) flag applies. The new parameters are
335 -block-left-list=s, or -bll=s, and --block-left-exclusion-list=s,
336 or -blxl=s. Previously the -bl flag was 'hardwired' to apply to
337 nearly all blocks. The default values of the new parameters
338 retain the the old default behavior but allow it to be changed.
340 - The default behavior of the -bli (-brace-left-and-indent) flag has changed
341 slightly. Previously, if you set -bli, then the -bl flag would also
342 automatically be set. Consequently, block types which were not included
343 in the default list for -bli would get -bl formatting. This is no longer done,
344 and these two styles are now controlled independently. The manual describes
345 the controls. If you want to recover the exact previous default behavior of
346 the -bli then add the -bl flag.
348 - A partial fix was made for issue for git #74. The -lp formatting style was
349 being lost when a one-line anonymous sub was followed by a closing brace.
351 - Fixed issue git #73, in which the -nfpva flag was not working correctly.
352 Some unwanted vertical alignments of spaced function perens
355 - Updated the man pages to clarify the flags -valign and -novalign
356 for turning vertical alignment on and off (issue git #72).
357 Added parameters -vc -vsc -vbc for separately turning off vertical
358 alignment of code, side comments and block comments.
360 - Fixed issue git #68, where a blank line following a closing code-skipping
361 comment, '#>>V', could be lost.
363 - This version runs 10 to 15 percent faster on large files than the
364 previous release due to optimizations made with the help of NYTProf.
366 - This version of perltidy was stress-tested for many cpu hours with
367 random input parameters. No instabilities, internal fault checks,
368 undefined variable references or other irregularities were seen.
370 - Numerous minor fixes have been made, mostly very rare formatting instabilities
371 found in random testing. An effort has been made to minimize changes to
372 existing formatting that these fixes produce, but occasional changes
373 may occur. Many of these updates are listed at:
375 https://github.com/perltidy/perltidy/blob/master/local-docs/BugLog.pod
380 <pre><code>- This release is being made mainly because of the next item, in which an
381 error message about an uninitialized value error message could be produced
382 in certain cases when format-skipping is used. The error message was
383 annoying but harmless to formatting.
385 - Fixed an undefined variable message, see git #67. When a format skipping
386 comment '#<<' is placed before the first line of code in a script, a
387 message 'Use of uninitialized value $Ktoken_vars in numeric ...' can
390 - A warning will no longer be given if a script has an opening code-skipping
391 comment '#<<V' which is not terminated with a closing comment '#>>V'. This
392 makes code-skipping and format-skipping behave in a similar way: an
393 opening comment without a corresponding closing comment will cause
394 the rest of a file to be skipped. If there is a question about which lines
395 are skipped, a .LOG file can be produced with the -g flag and it will have
398 - Removed the limit on -ci=n when -xci is set, reference: rt #136415.
399 This update removes a limit in the previous two versions in which the
400 value of -ci=n was limited to the value of -i=n when -xci was set.
401 This limit had been placed to avoid some formatting instabilities,
402 but recent coding improvements allow the limit to be removed.
404 - The -wn and -bbxx=n flags were not working together correctly. This has
407 - This version may produce occasional differences in formatting compared to
408 previous versions, mainly for lines which are near the specified line
409 length limit. This is due to ongoing efforts to eliminate edge cases of
410 formatting instability.
412 - Numerous minor fixes have been made. A complete list is at:
414 https://github.com/perltidy/perltidy/blob/master/local-docs/BugLog.pod
419 <pre><code>- This release adds several new requested parameters. No significant bugs have
420 been found since the last release, but a number of minor problems have been
423 - Added a new option '--code-skipping', requested in git #65, in which code
424 between comment lines '#<<V' and '#>>V' is passed verbatim to the output
425 stream without error checking. It is simmilar to --format-skipping
426 but there is no error checking of the skipped code. This can be useful for
427 skipping past code which employs an extended syntax.
429 - Added a new option for closing paren placement, -vtc=3, requested in rt #136417.
431 - Added flag -atnl, --add-terminal-newline, to help issue git #58.
432 This flag tells perltidy to terminate the last line of the output stream
433 with a newline character, regardless of whether or not the input stream
434 was terminated with a newline character. This is the default.
435 If this flag is negated, with -natnl, then perltidy will add a terminal
436 newline character to the the output stream only if the input
437 stream is terminated with a newline.
439 - Some nested structures formatted with the -lp indentation option may have
440 some changes in indentation. This is due to updates which were made to
441 prevent formatting instability when line lengths are limited by the maximum line
442 length. Most scripts will not be affected. If this causes unwanted formatting
443 changes, try increasing the --maximum-line-length by a few characters.
445 - Numerous minor fixes have been made. A complete list is at:
447 https://github.com/perltidy/perltidy/blob/master/local-docs/BugLog.pod
452 <pre><code>- This release fixes several non-critical bugs which have been found since the last
453 release. An effort has been made to keep existing formatting unchanged.
455 - Fixed issue git #57 regarding uninitialized warning flag.
457 - Added experimental flag -lpxl=s requested in issue git #56 to provide some
458 control over which containers get -lp indentation.
460 - Fixed issue git #55 regarding lack of coordination of the --break-before-xxx
461 flags and the --line-up-parens flag.
463 - Fixed issue git #54 regarding irregular application of the --break-before-paren
464 and similar --break-before-xxx flags, in which lists without commas were not
465 being formatted according to these flags.
467 - Fixed issue git #53. A flag was added to turn off alignment of spaced function
468 parens. If the --space-function-paren, -sfp flag is set, a side-effect is that the
469 spaced function parens may get vertically aligned. This can be undesirable,
470 so a new parameter '--function-paren-vertical-alignment', or '-fpva', has been
471 added to turn this vertical alignment off. The default is '-fpva', so that
472 existing formatting is not changed. Use '-nfpva' to turn off unwanted
473 vertical alignment. To illustrate the possibilities:
476 myfun( $aaa, $b, $cc );
477 mylongfun( $a, $b, $c );
480 myfun ( $aaa, $b, $cc );
481 mylongfun ( $a, $b, $c );
483 # perltidy -sfp -nfpva
484 myfun ( $aaa, $b, $cc );
485 mylongfun ( $a, $b, $c );
487 - Fixed issue git #51, a closing qw bare paren was not being outdented when
488 the -nodelete-old-newlines flag was set.
490 - Fixed numerous edge cases involving unusual parameter combinations which
491 could cause alternating output states. Most scripts will not be
492 changed by these fixes.
494 - A more complete list of updates is at
496 https://github.com/perltidy/perltidy/blob/master/local-docs/BugLog.pod
501 <pre><code>- Fixed issue git #49, -se breaks warnings exit status behavior.
502 The exit status flag was not always being set when the -se flag was set.
504 - Some improvements have been made in the method for aligning side comments.
505 One of the problems that was fixed is that there was a tendency for side comment
506 placement to drift to the right in long scripts. Programs with side comments
507 may have a few changes.
509 - Some improvements have been made in formatting qw quoted lists. This
510 fixes issue git #51, in which closing qw pattern delimiters not always
511 following the settings specified by the --closing-token-indentation=n settings.
512 Now qw closing delimiters ')', '}' and ']' follow these flags, and the
513 delimiter '>' follows the flag for ')'. Other qw pattern delimiters remain
514 indented as the are now. This change will cause some small formatting changes
515 in some existing programs.
517 - Another change involving qw lists is that they get full indentation,
518 rather than just continuation indentation, if
520 (1) the closing delimiter is one of } ) ] > and is on a separate line,
521 (2) the opening delimiter (i.e. 'qw{' ) is also on a separate line, and
522 (3) the -xci flag (--extended-continuation-indentation) is set.
524 This improves formatting when qw lists are contained in other lists. For example,
529 AntiqueWhite3 Bisque1 Bisque2 Bisque3 Bisque4
530 SlateBlue3 RoyalBlue1 SteelBlue2 DeepSkyBlue3
533 LightBlue1 DarkSlateGray1 Aquamarine2 DarkSeaGreen2
534 SeaGreen1 Yellow1 IndianRed1 IndianRed2 Tan1 Tan4
541 AntiqueWhite3 Bisque1 Bisque2 Bisque3 Bisque4
542 SlateBlue3 RoyalBlue1 SteelBlue2 DeepSkyBlue3
545 LightBlue1 DarkSlateGray1 Aquamarine2 DarkSeaGreen2
546 SeaGreen1 Yellow1 IndianRed1 IndianRed2 Tan1 Tan4
550 - Some minor improvements have been made to the rules for formatting
551 some edge vertical alignment cases, usually involving two dissimilar lines.
553 - A more complete list of updates is at
555 https://github.com/perltidy/perltidy/blob/master/local-docs/BugLog.pod
560 <pre><code>- Fixed issue git #47, incorrect welding of anonymous subs.
561 An incorrect weld format was being made when the --weld-nested-containers option
562 (-wn) was used in to format a function which returns a list of anonymous subs.
563 For example, the following snippet was incorrectly being welded.
565 $promises[$i]->then(
566 sub { $all->resolve(@_); () },
568 $results->[$i] = [@_];
569 $all->reject(@$results) if --$remaining <= 0;
574 This was due to an error introduced in v20201201 related to parsing sub
575 signatures. Reformatting with the current version will fix the problem.
580 <pre><code>- This release is being made primarily to make available a several new formatting
581 parameters, in particular -xci, -kbb=s, -kba=s, and -wnxl=s. No significant
582 bugs have been found since the previous release, but numerous minor issues have
583 been found and fixed as listed below.
585 - This version is about 20% faster than the previous version due to optimizations
586 made with the help of Devel::NYTProf.
588 - Added flag -wnxl=s, --weld-nested-exclusion-list=s, to provide control which containers
589 are welded with the --weld-nested-containers parameter. This is related to issue git #45.
591 - Merged pull request git #46 which fixes the docs regarding the -fse flag.
593 - Fixed issue git #45, -vtc=n flag was ignored when -wn was set.
595 - implement request RT #133649, delete-old-newlines selectively. Two parameters,
597 -kbb=s or --keep-old-breakpoints-before=s, and
598 -kba=s or --keep-old-breakpoints-after=s
600 were added to request that old breakpoints be kept before or after
601 selected token types. For example, -kbb='=>' means that newlines before
602 fat commas should be kept.
604 - Fix git #44, fix exit status for assert-tidy/untidy. The exit status was
605 always 0 for --assert-tidy if the user had turned off all error messages with
606 the -quiet flag. This has been fixed.
608 - Add flag -maxfs=n, --maximum-file-size-mb=n. This parameter is provided to
609 avoid causing system problems by accidentally attempting to format an
610 extremely large data file. The default is n=10. The command to increase
611 the limit to 20 MB for example would be -mfs=20. This only applies to
612 files specified by filename on the command line.
614 - Skip formatting if there are too many indentation level errors. This is
615 controlled with -maxle=n, --maximum-level-errors=n. This means that if
616 the ending indentation differs from the starting indentation by more than
617 n levels, the file will be output verbatim. The default is n=1.
618 To skip this check, set n=-1 or set n to a large number.
620 - A related new flag, --maximum-unexpected-errors=n, or -maxue=n, is available
621 but is off by default.
623 - Add flag -xci, --extended-continuation-indentation, regarding issue git #28
624 This flag causes continuation indentation to "extend" deeper into structures.
625 Since this is a fairly new flag, the default is -nxci to avoid disturbing
626 existing formatting. BUT you will probably see some improved formatting
627 in complex data structures by setting this flag if you currently use -ci=n
628 and -i=n with the same value of 'n' (as is the case if you use -pbp,
629 --perl-best-practices, where n=4).
631 - Fix issue git #42, clarify how --break-at-old-logical-breakpoints works.
632 The man page was updated to note that it does not cause all logical breakpoints
633 to be replicated in the output file.
635 - Fix issue git #41, typo in manual regarding -fsb.
637 - Fix issue git #40: when using the -bli option, a closing brace followed by
638 a semicolon was not being indented. This applies to braces which require
639 semicolons, such as a 'do' block.
641 - Added 'state' as a keyword.
643 - A better test for convergence has been added. When iterations are requested,
644 the new test will stop after the first pass if no changes in line break
645 locations are made. Previously, file checksums were used and required at least two
646 passes to verify convergence unless no formatting changes were made. With the new test,
647 only a single pass is needed when formatting changes are limited to adjustments of
648 indentation and whitespace on the lines of code. Extensive testing has been made to
649 verify the correctness of the new convergence test.
651 - Line breaks are now automatically placed after 'use overload' to
652 improve formatting when there are numerous overloaded operators. For
659 - A number of minor problems with parsing signatures and prototypes have
660 been corrected, particularly multi-line signatures. Some signatures
661 had previously been parsed as if they were prototypes, which meant the
662 normal spacing rules were not applied. For example
665 sub echo ($message= 'Hello World!' ) {
670 sub echo ( $message = 'Hello World!' ) {
674 - Numerous minor issues that the average user would not encounter were found
675 and fixed. They can be seen in the more complete list of updates at
677 https://github.com/perltidy/perltidy/blob/master/local-docs/BugLog.pod
682 <pre><code>- Robustness of perltidy has been significantly improved. Updating is recommended. Continual
683 automated testing runs began about 1 Sep 2020 and numerous issues have been found and fixed.
684 Many involve references to uninitialized variables when perltidy is fed random text and random
687 - Added the token '->' to the list of alignment tokens, as suggested in git
688 #39, so that it can be vertically aligned if a space is placed before them with -wls='->'.
690 - Added parameters -bbhb=n (--break-before-hash-brace=n), -bbsb=n (--break-before-square-bracket=n),
691 and -bbp=n (--break-before-paren=n) suggested in git #38. These provide control over the
692 opening container token of a multiple-line list. Related new parameters -bbhbi=n, -bbsbi=n, -bbpi=n
693 control indentation of these tokens.
695 - Added keyword 'isa'.
700 <pre><code>- Fixed bug git #37, an error when the combination -scbb -csc was used.
701 It occurs in perltidy versions 20200110, 20200619, and 20200822. What happens is
702 that when two consecutive lines with isolated closing braces had new side
703 comments generated by the -csc parameter, a separating newline was missing.
704 The resulting script will not then run, but worse, if it is reformatted with
705 the same parameters then closing side comments could be overwritten and data
708 This problem was found during automated random testing. The parameter
709 -scbb is rarely used, which is probably why this has not been reported. Please
710 upgrade your version.
712 - Added parameter --non-indenting-braces, or -nib, which prevents
713 code from indenting one level if it follows an opening brace marked
714 with a special side comment, '#<<<'. For example,
716 { #<<< a closure to contain lexical vars
718 my $var; # this line does not indent
722 # this line cannot 'see' $var;
724 This is on by default. If your code happens to have some
725 opening braces followed by '#<<<', and you
726 don't want this, you can use -nnib to deactivate it.
728 - Side comment locations reset at a line ending in a level 0 open
729 block, such as when a new multi-line sub begins. This is intended to
730 help keep side comments from drifting to far to the right.
735 <pre><code>- Fix RT #133166, encoding not set for -st. Also reported as RT #133171
738 This is a significant bug in version 20200616 which can corrupt data if
739 perltidy is run as a filter on encoded text.
742 <p><strong>Please upgrade</strong></p>
744 <pre><code>- Fix issue RT #133161, perltidy -html was not working on pod
746 - Fix issue git #33, allow control of space after '->'
748 - Vertical alignment has been improved. Numerous minor issues have
751 - Formatting with the -lp option is improved.
753 - Fixed issue git #32, misparse of bare 'ref' in ternary
755 - When --assert-tidy is used and triggers an error, the first difference
756 between input and output files is shown in the error output. This is
757 a partial response to issue git #30.
762 <pre><code>- Added support for Switch::Plain syntax, issue git #31.
764 - Fixed minor problem where trailing 'unless' clauses were not
765 getting vertically aligned.
767 - Added a parameter --logical-padding or -lop to allow logical padding
768 to be turned off. Requested by git #29. This flag is on by default.
769 The man pages have examples.
771 - Added a parameter -kpit=n to control spaces inside of parens following
772 certain keywords, requested in git#26. This flag is off by default.
774 - Added fix for git#25, improve vertical alignment for long lists with
775 varying numbers of items per line.
777 - calls to the module Perl::Tidy can now capture any output produced
778 by a debug flag or one of the 'tee' flags through the new 'debugfile' and
779 'teefile' call parameters. These output streams are rarely used but
780 they are now treated the same as any 'logfile' stream.
782 - add option --break-at-old-semicolon-breakpoints', -bos, requested
783 in RT#131644. This flag will keep lines beginning with a semicolon.
785 - Added --use-unicode-gcstring to control use of Unicode::GCString for
786 evaluating character widths of encoded data. The default is
787 not to use this (--nouse-unicode-gcstring). If this flag is set,
788 perltidy will look for Unicode::GCString and, if found, will use it
789 to evaluate character display widths. This can improve displayed
790 vertical alignment for files with wide characters. It is a nice
791 feature but it is off by default to avoid conflicting formatting
792 when there are multiple developers. Perltidy installation does not
793 require Unicode::GCString, so users wanting to use this feature need
794 set this flag and also to install Unicode::GCString separately.
796 - Added --character-encoding=guess or -guess to have perltidy guess
797 if a file (or other input stream) is encoded as -utf8 or some
798 other single-byte encoding. This is useful when processing a mixture
799 of file types, such as utf8 and latin-1.
801 Please Note: The default encoding has been set to be 'guess'
802 instead of 'none'. This seems like the best default, since
803 it allows perltidy work properly with both
804 utf8 files and older latin-1 files. The guess mode uses Encode::Guess,
805 which is included in standard perl distributions, and only tries to
806 guess if a file is utf8 or not, never any other encoding. If the guess is
807 utf8, and if the file successfully decodes as utf8, then it the encoding
808 is assumed to be utf8. Otherwise, no encoding is assumed.
809 If you do not want to use this new default guess mode, or have a
810 problem with it, you can set --character-encoding=none (the previous
811 default) or --character-encoding=utf8 (if you deal with utf8 files).
813 - Specific encodings of input files other than utf8 may now be given, for
814 example --character-encoding=euc-jp.
816 - Fix for git#22, Preserve function signature on a single line. An
817 unwanted line break was being introduced when a closing signature paren
818 followed a closing do brace.
820 - Fix RT#132059, the -dac parameter was not working and caused an error exit
822 - When -utf8 is used, any error output is encoded as utf8
824 - Fix for git#19, adjust line break around an 'xor'
826 - Fix for git#18, added warning for missing comma before unknown bare word.
831 <pre><code>- This release adds a flag to control the feature RT#130394 (allow short nested blocks)
832 introduced in the previous release. Unfortunately that feature breaks
833 RPerl installations, so a control flag has been introduced and that feature is now
834 off by default. The flag is:
836 --one-line-block-nesting=n, or -olbn=n, where n is an integer as follows:
838 -olbn=0 break nested one-line blocks into multiple lines [new DEFAULT]
839 -olbn=1 stable; keep existing nested-one line blocks intact [previous DEFAULT]
841 For example, consider this input line:
843 foreach (@list) { if ($_ eq $asked_for) { last } ++$found }
845 The new default behavior (-olbn=0), and behavior prior to version 20191203, is to break it into multiple lines:
848 if ( $_ eq $asked_for ) { last }
852 To keep nested one-line blocks such as this on a single line you can add the parameter -olbn=1.
854 - Fixed issue RT#131288: parse error for un-prototyped constant function without parenthesized
855 call parameters followed by ternary.
857 - Fixed issue RT#131360, installation documentation. Added a note that the binary
858 'perltidy' comes with the Perl::Tidy module. They can both normally be installed with
864 <pre><code>- Fixed issue RT#131115: -bli option not working correctly.
865 Closing braces were not indented in some cases due to a glitch
866 introduced in version 20181120.
868 - Fixed issue RT#130394: Allow short nested blocks. Given the following
870 $factorial = sub { reduce { $a * $b } 1 .. 11 };
872 Previous versions would always break the sub block because it
873 contains another block (the reduce block). The fix keeps
874 short one-line blocks such as this intact.
876 - Implement issue RT#130640: Allow different subroutine keywords.
877 Added a flag --sub-alias-list=s or -sal=s, where s is a string with
878 one or more aliases for 'sub', separated by spaces or commas.
881 perltidy -sal='method fun'
883 will cause the perltidy to treat the words 'method' and 'fun' to be
884 treated the same as if they were 'sub'.
886 - Added flag --space-prototype-paren=i, or -spp=i, to control spacing
887 before the opening paren of a prototype, where i=0, 1, or 2:
889 i=1 follow input [current and default]
892 Previously, perltidy always followed the input.
893 For example, given the following input
898 sub usage(); # i=0 [no space]
899 sub usage(); # i=1 [default; follows input]
900 sub usage (); # i=2 [space]
902 - Fixed issue git#16, minor vertical alignment issue.
904 - Fixed issue git#10, minor conflict of -wn and -ce
906 - Improved some vertical alignments involving two lines.
911 <pre><code>- fixed issue RT#130344: false warning "operator in print statement"
914 - fixed issue RT#130304: standard error output should include filename.
915 When perltidy error messages are directed to the standard error output
916 with -se or --standard-error-output, the message lines now have a prefix
917 'filename:' for clarification in case multiple files
918 are processed, where 'filename' is the name of the input file. If
919 input is from the standard input the displayed filename is '<stdin>',
920 and if it is from a data structure then displayed filename
921 is '<source_stream>'.
923 - implement issue RT#130425: check mode. A new flag '--assert-tidy'
924 will cause an error message if the output script is not identical to
925 the input script. For completeness, the opposite flag '--assert-untidy'
926 has also been added. The next item, RT#130297, insures that the script
927 will exit with a non-zero exit flag if the assertion fails.
929 - fixed issue RT#130297; the perltidy script now exits with a nonzero exit
930 status if it wrote to the standard error output. Prevously only fatal
931 run errors produced a non-zero exit flag. Now, even non-fatal messages
932 requested with the -w flag will cause a non-zero exit flag. The exit
933 flag now has these values:
936 1 = perltidy could not run to completion due to errors
937 2 = perltidy ran to completion with error messages
939 - added warning message for RT#130008, which warns of conflicting input
940 parameters -iob and -bom or -boc.
942 - fixed RT#129850; concerning a space between a closing block brace and
943 opening bracket or brace, as occurs before the '[' in this line:
945 my @addunix = map { File::Spec::Unix->catfile( @ROOT, @$_ ) } ['b'];
947 Formerly, any space was removed. Now it is optional, and the output will
950 - fixed issue git#13, needless trailing whitespace in error message
952 - fixed issue git#9: if the -ce (--cuddled-else) flag is used,
953 do not try to form new one line blocks for a block type
954 specified with -cbl, particularly map, sort, grep
956 - iteration speedup for unchanged code. Previously, when iterations were
957 requested, at least two formatting passes were made. Now just a single pass
958 is made if the formatted code is identical to the input code.
960 - some improved vertical alignments
965 <pre><code>- rt #128477: Prevent inconsistent owner/group and setuid/setgid bits.
966 In the -b (--backup-and-modify-in-place) mode, an attempt is made to set ownership
967 of the output file equal to the input file, if they differ.
968 In all cases, if the final output file ownership differs from input file, any setuid/setgid bits are cleared.
970 - Added option -bom (--break-at-old-method-breakpoints) by
971 merrillymeredith which preserves breakpoints of method chains. Modified to also handle a cuddled call style.
973 - Merged patch to fix Windows EOL translation error with UTF-8 written by
974 Ron Ivy. This update prevents automatic conversion to 'DOS' CRLF line
975 endings. Also, Windows system testing at the appveyor site is working again.
977 - RT #128280, added flag --one-line-block-semicolons=n (-olbs=n)
978 to control semicolons in one-line blocks. The values of n are:
979 n=0 means no semicolons termininating simple one-line blocks
980 n=1 means stable; do not change from input file [DEFAULT and current]
981 n=2 means always add semicolons in one-line blocks
982 The current behavior corresponds to the default n=1.
984 - RT #128216, Minor update to prevent inserting unwanted blank line at
985 indentation level change. This should not change existing scripts.
987 - RT #81852: Improved indentation when quoted word (qw) lists are
988 nested within other containers using the --weld-nested (-wn) flag.
989 The example given previously (below) is now closer to what it would
990 be with a simple list instead of qw:
1004 - RT#12764, introduced new feature allowing placement of blanks around
1005 sequences of selected keywords. This can be activated with the -kgb*
1006 series of parameters described in the manual.
1008 - Rewrote vertical algnment module. It is better at finding
1009 patterns in complex code. For example,
1012 /^-std$/ && do { $std = 1; next; };
1013 /^--$/ && do { @link_args = @argv; last; };
1014 /^-I(.*)/ && do { $path = $1 || shift @argv; next; };
1017 /^-std$/ && do { $std = 1; next; };
1018 /^--$/ && do { @link_args = @argv; last; };
1019 /^-I(.*)/ && do { $path = $1 || shift @argv; next; };
1021 - Add repository URLs to META files
1023 - RT #118553, "leave only one newline at end of file". This option was not
1024 added because of undesirable side effects, but a new filter script
1025 was added which can do this, "examples/delete_ending_blank_lines.pl".
1030 <pre><code>- fix RT#127736 Perl-Tidy-20181119 has the EXE_FILES entry commented out in
1031 Makefile.PL so it doesn't install the perltidy script or its manpage.
1036 <pre><code>- Removed test case 'filter_example.t' which was causing a failure on a
1037 Windows installation for unknown reasons, possibly due to an unexpected
1038 perltidyrc being read by the test script. Added VERSION numbers to all
1044 <pre><code>- Fixed RT #126965, in which a ternary operator was misparsed if immediately
1045 following a function call without arguments, such as:
1046 my $restrict_customer = shift ? 1 : 0;
1048 - Fixed RT #125012: bug in -mangle --delete-all-comments
1049 A needed blank space before bareword tokens was being removed when comments
1052 - Fixed RT #81852: Stacked containers and quoting operators. Quoted words
1053 (qw) delimited by container tokens ('{', '[', '(', '<') are now included in
1054 the --weld-nested (-wn) flag:
1068 - The cuddled-else (-ce) coding was merged with the new cuddled-block (-cb)
1069 coding. The change is backward compatible and simplifies input.
1070 The --cuddled-block-option=n (-cbo=n) flag now applies to both -ce and -cb
1071 formatting. In fact the -cb flag is just an alias for -ce now.
1073 - Fixed RT #124594, license text desc. changed from 'GPL-2.0+' to 'gpl_2'
1075 - Fixed bug in which a warning about a possible code bug was issued in a
1076 script with brace errors.
1078 - added option --notimestamp or -nts to eliminate any time stamps in output
1079 files. This is used to prevent differences in test scripts from causing
1080 failure at installation. For example, the -cscw option will put a date
1081 stamp on certain closing side comments. We need to avoid this in order
1082 to test this feature in an installation test.
1084 - Fixed bug with the entab option, -et=8, in which the leading space of
1085 some lines was was not entabbed. This happened in code which was adjusted
1086 for vertical alignment and in hanging side comments. Thanks to Glenn.
1088 - Fixed RT #127633, undesirable line break after return when -baao flag is set
1090 - Fixed RT #127035, vertical alignment. Vertical alignment has been improved
1091 in several ways. Thanks especially to Michael Wardman and Glenn for sending
1094 - Alignment of the =~ operators has been reactivated.
1097 $service_profile =~ s/^\s+|\s+$//g;
1098 $host_profile =~ s/^\s+|\s+$//g;
1101 $service_profile =~ s/^\s+|\s+$//g;
1102 $host_profile =~ s/^\s+|\s+$//g;
1104 - Alignment of the // operator has been reactivated.
1107 is( pop // 7, 7, 'pop // ... works' );
1108 is( pop() // 7, 0, 'pop() // ... works' );
1109 is( pop @ARGV // 7, 3, 'pop @array // ... works' );
1112 is( pop // 7, 7, 'pop // ... works' );
1113 is( pop() // 7, 0, 'pop() // ... works' );
1114 is( pop @ARGV // 7, 3, 'pop @array // ... works' );
1116 - The rules for alignment of just two lines have been adjusted,
1117 hopefully to be a little better overall. In some cases, two
1118 lines which were previously unaligned are now aligned, and vice-versa.
1121 $expect = "1$expect" if $expect =~ /^e/i;
1122 $p = "1$p" if defined $p and $p =~ /^e/i;
1125 $expect = "1$expect" if $expect =~ /^e/i;
1126 $p = "1$p" if defined $p and $p =~ /^e/i;
1129 - RT #106493; source code repository location has been added to docs; it is
1130 https://github.com/perltidy/perltidy
1132 - The packaging for this version has changed. The Tidy.pm module is much
1133 smaller. Supporting modules have been split out from it and placed below
1134 it in the path Perl/Tidy/*.
1136 - A number of new installation test cases have been added. Updates are now
1137 continuously tested at Travis CI against versions back to Perl 5.08.
1142 <pre><code>- RT #124469, #124494, perltidy often making empty files. The previous had
1143 an index error causing it to fail, particularly in version 5.18 of Perl.
1145 Please avoid version 20180219.
1150 <pre><code>- RT #79947, cuddled-else generalization. A new flag -cb provides
1151 'cuddled-else' type formatting for an arbitrary type of block chain. The
1152 default is try-catch-finally, but this can be modified with the
1155 - Fixed RT #124298: add space after ! operator without breaking !! secret
1158 - RT #123749: numerous minor improvements to the -wn flag were made.
1160 - Fixed a problem with convergence tests in which iterations were stopping
1163 - Here doc targets for <<~ type here-docs may now have leading whitespace.
1165 - Fixed RT #124354. The '-indent-only' flag was not working correctly in the
1166 previous release. A bug in version 20180101 caused extra blank lines
1169 - Issue RT #124114. Some improvements were made in vertical alignment
1170 involving 'fat commas'.
1175 <pre><code>- Added new flag -wn (--weld-nested-containers) which addresses these issues:
1176 RT #123749: Problem with promises;
1177 RT #119970: opening token stacking strange behavior;
1178 RT #81853: Can't stack block braces
1180 This option causes closely nested pairs of opening and closing containers
1181 to be "welded" together and essentially be formatted as a single unit,
1182 with just one level of indentation.
1184 Since this is a new flag it is set to be "off" by default but it has given
1185 excellent results in testing.
1187 EXAMPLE 1, multiple blocks, default formatting:
1190 next if $x == $y; # do something here
1192 } until $x++ > $z;
1197 } } until $x++ > $z;
1199 EXAMPLE 2, three levels of wrapped function calls, default formatting:
1203 translate( param('verb') ), param('tense'),
1211 translate( param('verb') ),
1212 param('tense'), param('person')
1215 # EXAMPLE 3, chained method calls, default formatting:
1216 get('http://mojolicious.org')->then(
1219 say $mojo->res->code;
1220 return get('http://metacpan.org');
1225 say $cpan->res->code;
1230 warn "Something went wrong: $err";
1235 get('http://mojolicious.org')->then( sub {
1237 say $mojo->res->code;
1238 return get('http://metacpan.org');
1241 say $cpan->res->code;
1242 } )->catch( sub {
1244 warn "Something went wrong: $err";
1248 - Fixed RT #114359: Missparsing of "print $x ** 0.5;
1250 - Deactivated the --check-syntax flag for better security. It will be
1253 - Corrected minimum perl version from 5.004 to 5.008 based on perlver
1254 report. The change is required for coding involving wide characters.
1256 - For certain severe errors, the source file will be copied directly to the
1257 output without formatting. These include ending in a quote, ending in a
1258 here doc, and encountering an unidentified character.
1263 <pre><code>- RT #123749, partial fix. "Continuation indentation" is removed from lines
1264 with leading closing parens which are part of a call chain.
1265 For example, the call to pack() is is now outdented to the starting
1266 indentation in the following experession:
1270 -text => "New Document",
1271 -command => \&new_document
1273 -side => 'bottom',
1279 -text => "New Document",
1280 -command => \&new_document
1282 -side => 'bottom',
1286 This modification improves readability of complex expressions, especially
1287 when the user uses the same value for continuation indentation (-ci=n) and
1288 normal indentation (-i=n). Perltidy was already programmed to
1289 do this but a minor bug was preventing it.
1291 - RT #123774, added flag to control space between a backslash and a single or
1292 double quote, requested by Robert Rothenberg. The issue is that lines like
1297 confuse syntax highlighters unless a space is left between the backslash and
1300 The new flag to control this is -sbq=n (--space-backslash-quote=n),
1301 where n=0 means no space, n=1 means follow existing code, n=2 means always
1302 space. The default is n=1, meaning that a space will be retained if there
1303 is one in the source code.
1305 - Fixed RT #123492, support added for indented here doc operator <<~ added
1306 in v5.26. Thanks to Chris Weyl for the report.
1308 - Fixed docs; --closing-side-comment-list-string should have been just
1309 --closing-side-comment-list. Thanks to F.Li.
1311 - Added patch RT #122030] Perl::Tidy sometimes does not call binmode.
1312 Thanks to Irilis Aelae.
1314 - Fixed RT #121959, PERLTIDY doesn't honor the 'three dot' notation for
1315 locating a config file using environment variables. Thanks to John
1318 - Minor improvements to formatting, in which some additional vertical
1319 aligmnemt is done. Thanks to Keith Neargarder.
1321 - RT #119588. Vertical alignment is no longer done for // operator.
1326 <pre><code>- Fixed debian #862667: failure to check for perltidy.ERR deletion can lead
1327 to overwriting arbitrary files by symlink attack. Perltidy was continuing
1328 to write files after an unlink failure. Thanks to Don Armstrong
1331 - Fixed RT #116344, perltidy fails on certain anonymous hash references:
1332 in the following code snippet the '?' was misparsed as a pattern
1333 delimiter rather than a ternary operator.
1334 return ref {} ? 1 : 0;
1336 - Fixed RT #113792: misparsing of a fat comma (=>) right after
1337 the __END__ or __DATA__ tokens. These keywords were getting
1338 incorrectly quoted by the following => operator.
1340 - Fixed RT #118558. Custom Getopt::Long configuration breaks parsing
1341 of perltidyrc. Perltidy was resetting the users configuration too soon.
1343 - Fixed RT #119140, failure to parse double diamond operator. Code to
1344 handle this new operator has been added.
1346 - Fixed RT #120968. Fixed problem where -enc=utf8 didn't work
1347 with --backup-and-modify-in-place. Thanks to Heinz Knutzen for this patch.
1349 - Fixed minor formatting issue where one-line blocks for subs with signatures
1350 were unnecessarily broken
1352 - RT #32905, patch to fix utf-8 error when output was STDOUT.
1354 - RT #79947, improved spacing of try/catch/finally blocks. Thanks to qsimpleq
1357 - Fixed #114909, Anonymous subs with signatures and prototypes misparsed as
1358 broken ternaries, in which a statement such as this was not being parsed
1360 return sub ( $fh, $out ) : prototype(*$) { ... }
1362 - Implemented RT #113689, option to introduces spaces after an opening block
1363 brace and before a closing block brace. Four new optional controls are
1364 added. The first two define the minimum number of blank lines to be
1367 -blao=i or --blank-lines-after-opening-block=i
1368 -blbc=i or --blank-lines-before-closing-block=i
1370 where i is an integer, the number of lines (the default is 0).
1372 The second two define the types of blocks to which the first two apply
1374 -blaol=s or --blank-lines-after-opening-block-list=s
1375 -blbcl=s or --blank-lines-before-closing-block-list=s
1377 where s is a string of possible block keywords (default is just 'sub',
1378 meaning a named subroutine).
1380 For more information please see the documentation.
1382 - The method for specifying block types for certain input parameters has
1383 been generalized to distinguish between normal named subroutines and
1384 anonymous subs. The keyword for normal subroutines remains 'sub', and
1385 the new keyword for anonymous subs is 'asub'.
1387 - Minor documentation changes. The BUGS sections now have a link
1388 to CPAN where most open bugs and issues can be reviewed and bug reports
1389 can be submitted. The information in the AUTHOR and CREDITS sections of
1390 the man pages have been removed from the man pages to streamline the
1391 documentation. This information is still in the source code.
1396 <pre><code>- RT #112534. Corrected a minor problem in which an unwanted newline
1397 was placed before the closing brace of an anonymous sub with
1398 a signature, if it was in a list. Thanks to Dmytro Zagashev.
1400 - Corrected a minor problem in which occasional extra indentation was
1401 given to the closing brace of an anonymous sub in a list when the -lp
1407 <pre><code> - RT #104427. Added support for signatures.
1409 - RT #111512. Changed global warning flag $^W = 1 to use warnings;
1410 Thanks to Dmytro Zagashev.
1412 - RT #110297, added support for new regexp modifier /n
1413 Thanks to Dmytro Zagashev.
1415 - RT #111519. The -io (--indent-only) and -dac (--delete-all-comments)
1416 can now both be used in one pass. Thanks to Dmitry Veltishev.
1418 - Patch to avoid error message with 'catch' used by TryCatch, as in
1422 Thanks to Nick Tonkin.
1424 - RT #32905, UTF-8 coding is now more robust. Thanks to qsimpleq
1425 and Dmytro for patches.
1427 - RT #106885. Added string bitwise operators ^. &. |. ~. ^.= &.= |.=
1429 - Fixed RT #107832 and #106492, lack of vertical alignment of two lines
1430 when -boc flag (break at old commas) is set. This bug was
1431 inadvertently introduced in previous bug fix RT #98902.
1433 - Some common extensions to Perl syntax are handled better.
1434 In particular, the following snippet is now foratted cleanly:
1436 method deposit( Num $amount) {
1437 $self->balance( $self->balance + $amount );
1440 A new flag -xs (--extended-syntax) was added to enable this, and the default
1443 In previous versions, and now only when -nxs is set, this snippet of code
1444 generates the following error message:
1446 "syntax error at ') {', didn't see one of: case elsif for foreach given if switch unless until when while"
1451 <pre><code> - Fixed RT# 105484, Invalid warning about 'else' in 'switch' statement. The
1452 warning happened if a 'case' statement did not use parens.
1454 - Fixed RT# 101547, misparse of // caused error message. Also..
1456 - Fixed RT# 102371, misparse of // caused unwated space in //=
1458 - Fixed RT# 100871, "silent failure of HTML Output on Windows".
1459 Changed calls to tempfile() from:
1460 my ( $fh_tmp, $tmpfile ) = tempfile();
1461 to have the full path name:
1462 my ( $fh_tmp, $tmpfile ) = File::Temp::tempfile()
1463 because of problems in the Windows version reported by Dean Pearce.
1465 - Fixed RT# 99514, calling the perltidy module multiple times with
1466 a .perltidyrc file containing the parameter --output-line-ending
1467 caused a crash. This was a glitch in the memoization logic.
1469 - Fixed RT#99961, multiple lines inside a cast block caused unwanted
1470 continuation indentation.
1472 - RT# 32905, broken handling of UTF-8 strings.
1473 A new flag -utf8 causes perltidy assume UTF-8 encoding for input and
1474 output of an io stream. Thanks to Sebastian Podjasek for a patch.
1475 This feature may not work correctly in older versions of Perl.
1476 It worked in a linux version 5.10.1 but not in a Windows version 5.8.3 (but
1477 otherwise perltidy ran correctly).
1479 - Warning files now report perltidy VERSION. Suggested by John Karr.
1481 - Fixed long flag --nostack-closing-tokens (-nsct has always worked though).
1482 This was due to a typo. This also fixed --nostack-opening-tokens to
1483 behave correctly. Thanks to Rob Dixon.
1488 <pre><code>- Fixed RT #94902: abbreviation parsing in .perltidyrc files was not
1489 working for multi-line abbreviations. Thanks to Eric Fung for
1492 - Fixed RT #95708, misparsing of a hash when the first key was a perl
1493 keyword, causing a semicolon to be incorrectly added.
1495 - Fixed RT #94338 for-loop in a parenthesized block-map. A code block within
1496 parentheses of a map, sort, or grep function was being mistokenized. In
1497 rare cases this could produce in an incorrect error message. The fix will
1498 produce some minor formatting changes. Thanks to Daniel Trizen
1499 discovering and documenting this.
1501 - Fixed RT #94354, excess indentation for stacked tokens. Thanks to
1502 Colin Williams for supplying a patch.
1504 - Added support for experimental postfix dereferencing notation introduced in
1505 perl 5.20. RT #96021.
1507 - Updated documentation to clarify the behavior of the -io flag
1508 in response to RT #95709. You can add -noll or -l=0 to prevent
1509 long comments from being outdented when -io is used.
1511 - Added a check to prevent a problem reported in RT #81866, where large
1512 scripts which had been compressed to a single line could not be formatted
1513 because of a check for VERSION for MakeMaker. The workaround was to
1514 use -nvpl, but this shouldn't be necessary now.
1516 - Fixed RT #96101; Closing brace of anonymous sub in a list was being
1517 indented. For example, the closing brace of the anonymous sub below
1518 will now be lined up with the word 'callback'. This problem
1519 occurred if there was no comma after the closing brace of the anonymous sub.
1520 This update may cause minor changes to formatting of code with lists
1521 of anonymous subs, especially TK code.
1528 path => '/_Operate/Transcode and split',
1529 callback => sub {
1530 return 1 if not $self->project_opened;
1531 $self->comp('project')->transcode( split => 1 );
1541 path => '/_Operate/Transcode and split',
1542 callback => sub {
1543 return 1 if not $self->project_opened;
1544 $self->comp('project')->transcode( split => 1 );
1552 <pre><code>- Fixed RT #94190 and debian Bug #742004: perltidy.LOG file left behind.
1553 Thanks to George Hartzell for debugging this. The problem was
1554 caused by the memoization speedup patch in version 20121207. An
1555 unwanted flag was being set which caused a LOG to be written if
1556 perltidy was called multiple times.
1558 - New default behavior for LOG files: If the source is from an array or
1559 string (through a call to the perltidy module) then a LOG output is only
1560 possible if a logfile stream is specified. This is to prevent
1561 unexpected perltidy.LOG files.
1563 - Fixed debian Bug #740670, insecure temporary file usage. File::Temp is now
1564 used to get a temporary file. Thanks to Don Anderson for a patch.
1566 - Any -b (--backup-and-modify-in-place) flag is silently ignored when a
1567 source stream, destination stream, or standard output is used.
1568 This is because the -b flag may have been in a .perltidyrc file and
1569 warnings break Test::NoWarnings. Thanks to Marijn Brand.
1574 <pre><code>- Fixed RT #88020. --converge was not working with wide characters.
1576 - Fixed RT #78156. package NAMESPACE VERSION syntax not accepted.
1578 - First attempt to fix RT #88588. INDEX END tag change in pod2html breaks
1579 perltidy -html. I put in a patch which should work but I don't yet have
1580 a way of testing it.
1585 <pre><code>- Fixed RT #87107, spelling
1590 <pre><code>- Fixed RT #87502, incorrect of parsing of smartmatch before hash brace
1592 - Added feature request RT #87330, trim whitespace after POD.
1593 The flag -trp (--trim-pod) will trim trailing whitespace from lines of POD
1598 <pre><code>- Fixed RT #86929, #86930, missing lhs of assignment.
1600 - Fixed RT #84922, moved pod from Tidy.pm into Tidy.pod
1605 <pre><code>- The flag -cab=n or --comma-arrow-breakpoints=n has been generalized
1606 to give better control over breaking open short containers. The
1607 possible values are now:
1609 n=0 break at all commas after =>
1610 n=1 stable: break at all commas after => if container is open,
1611 EXCEPT FOR one-line containers
1612 n=2 break at all commas after =>, BUT try to form the maximum
1613 maximum one-line container lengths
1614 n=3 do not treat commas after => specially at all
1615 n=4 break everything: like n=0 but also break a short container with
1616 a => not followed by a comma
1617 n=5 stable: like n=1 but ALSO break at open one-line containers (default)
1619 New values n=4 and n=5 have been added to allow short blocks to be
1620 broken open. The new default is n=5, stable. It should more closely
1621 follow the breaks in the input file, and previously formatted code
1622 should remain unchanged. If this causes problems use -cab=1 to recover
1623 the former behavior. Thanks to Tony Maszeroski for the suggestion.
1625 To illustrate the need for the new options, if perltidy is given
1626 the following code, then the old default (-cab=1) was to close up
1627 the 'index' container even if it was open in the source. The new
1628 default (-cab=5) will keep it open if it was open in the source.
1633 'key' => 'value',
1643 - New debug flag --memoize (-mem). This version contains a
1644 patch supplied by Jonathan Swartz which can significantly speed up
1645 repeated calls to Perl::Tidy::perltidy in a single process by caching
1646 the result of parsing the formatting parameters. A factor of up to 10
1647 speedup was achieved for masontidy (https://metacpan.org/module/masontidy).
1648 The memoization patch is on by default but can be deactivated for
1649 testing with -nmem (or --no-memoize).
1651 - New flag -tso (--tight-secret-operators) causes certain perl operator
1652 sequences (secret operators) to be formatted "tightly" (without spaces).
1653 The most common of these are 0 + and + 0 which become 0+ and +0. The
1654 operators currently modified by this flag are:
1655 =( )= 0+ +0 ()x!! ~~<> ,=>
1656 Suggested by by Philippe Bruhat. See https://metacpan.org/module/perlsecret
1657 This flag is off by default.
1659 - New flag -vmll (--variable-maximum-line-length) makes the maximum
1660 line length increase with the nesting depth of a line of code.
1661 Basically, it causes the length of leading whitespace to be ignored when
1662 setting line breaks, so the formatting of a block of code is independent
1663 of its nesting depth. Try this option if you have deeply nested
1664 code or data structures, perhaps in conjunction with the -wc flag
1665 described next. The default is not todo this.
1667 - New flag -wc=n (--whitespace-cycle=n) also addresses problems with
1668 very deeply nested code and data structures. When this parameter is
1669 used and the nesting depth exceeds the value n, the leading whitespace
1670 will be reduced and start at 1 again. The result is that deeply
1671 nested blocks of code will shift back to the left. This occurs cyclically
1672 to any nesting depth. This flag may be used either with or without -vmll.
1673 The default is not to use this (-wc=0).
1675 - Fixed RT #78764, error parsing smartmatch operator followed by anonymous
1676 hash or array and then a ternary operator; two examples:
1678 qr/3/ ~~ ['1234'] ? 1 : 0;
1679 map { $_ ~~ [ '0', '1' ] ? 'x' : 'o' } @a;
1681 - Fixed problem with specifying spaces around arrows using -wls='->'
1682 and -wrs='->'. Thanks to Alain Valleton for documenting this problem.
1684 - Implemented RT #53183, wishlist, lines of code with the same indentation
1685 level which are contained with multiple stacked opening and closing tokens
1686 (requested with flags -sot -sct) now have reduced indentation.
1689 $sender->MailMsg(
1692 subject => $subject,
1697 # OLD: perltidy -sot -sct
1698 $sender->MailMsg( {
1700 subject => $subject,
1704 # NEW: perltidy -sot -sct
1705 $sender->MailMsg( {
1707 subject => $subject,
1711 - New flag -act=n (--all-containers-tightness=n) is an abbreviation for
1712 -pt=n -sbt=n -bt=n -bbt=n, where n=0,1, or 2. It simplifies input when all
1713 containers have the same tightness. Using the same example:
1715 # NEW: perltidy -sot -sct -act=2
1716 $sender->MailMsg({
1718 subject => $subject,
1722 - New flag -sac (--stack-all-containers) is an abbreviation for -sot -sct
1723 This is part of wishlist item RT #53183. Using the same example again:
1725 # NEW: perltidy -sac -act=2
1726 $sender->MailMsg({
1728 subject => $subject,
1732 - new flag -scbb (--stack-closing-block-brace) causes isolated closing
1733 block braces to stack as in the following example. (Wishlist item RT#73788)
1740 push( @lines, "$w1 $w2 $w3 $w4\n" );
1751 push( @lines, "$w1 $w2 $w3 $w4\n" );
1754 There is, at present, no flag to place these closing braces at the end
1755 of the previous line. It seems difficult to develop good rules for
1756 doing this for a wide variety of code and data structures.
1758 - Parameters defining block types may use a wildcard '*' to indicate
1759 all block types. Previously it was not possible to include bare blocks.
1761 - A flag -sobb (--stack-opening-block-brace) has been introduced as an
1762 alias for -bbvt=2 -bbvtl='*'. So for example the following test code:
1764 {{{{{{{ $testing }}}}}}}
1766 cannot be formatted as above but can at least be kept vertically compact
1767 using perltidy -sobb -scbb
1769 { { { { { { { $testing
1772 Or even, perltidy -sobb -scbb -i=1 -bbt=2
1777 - Error message improved for conflicts due to -pbp; thanks to Djun Kim.
1779 - Fixed RT #80645, error parsing special array name '@$' when used as
1782 - Eliminated the -chk debug flag which was included in version 20010406 to
1783 do a one-time check for a bug with multi-line quotes. It has not been
1786 - Numerous other minor formatting improvements.
1791 <pre><code>- Added flag -iscl (--ignore-side-comment-lengths) which causes perltidy
1792 to ignore the length of side comments when setting line breaks,
1793 RT #71848. The default is to include the length of side comments when
1794 breaking lines to stay within the length prescribed by the -l=n
1795 maximum line length parameter. For example,
1797 Default behavior on a single line with long side comment:
1798 $vmsfile =~ s/;[\d\-]*$//
1799 ; # Clip off version number; we can use a newer version as well
1801 perltidy -iscl leaves the line intact:
1803 $vmsfile =~ s/;[\d\-]*$//; # Clip off version number; we can use a newer version as well
1805 - Fixed RT #78182, side effects with STDERR. Error handling has been
1806 revised and the documentation has been updated. STDERR can now be
1807 redirected to a string reference, and perltidy now returns an
1808 error flag instead of calling die when input errors are detected.
1809 If the error flag is set then no tidied output was produced.
1810 See man Perl::Tidy for an example.
1812 - Fixed RT #78156, erroneous warning message for package VERSION syntax.
1814 - Added abbreviations -conv (--converge) to simplify iteration control.
1815 -conv is equivalent to -it=4 and will insure that the tidied code is
1816 converged to its final state with the minimum number of iterations.
1818 - Minor formatting modifications have been made to insure convergence.
1820 - Simplified and hopefully improved the method for guessing the starting
1821 indentation level of entabbed code. Added flag -dt=n (--default_tabsize=n)
1822 which might be helpful if the guessing method does not work well for
1825 - Added support for stacked labels, upper case X/B in hex and binary, and
1828 - Eliminated warning messages for using keyword names as constants.
1833 <pre><code>- Corrected problem introduced by using a chomp on scalar references, RT #77978
1835 - Added support for Perl 5.14 package block syntax, RT #78114.
1837 - A convergence test is made if three or more iterations are requested with
1838 the -it=n parameter to avoid wasting computer time. Several hundred Mb of
1839 code gleaned from the internet were searched with the results that:
1840 - It is unusual for two iterations to be required unless a major
1841 style change is being made.
1842 - Only one case has been found where three iterations were required.
1843 - No cases requiring four iterations have been found with this version.
1844 For the previous version several cases where found the results could
1845 oscillate between two semi-stable states. This version corrects this.
1847 So if it is important that the code be converged it is okay to set -it=4
1848 with this version and it will probably stop after the second iteration.
1850 - Improved ability to identify and retain good line break points in the
1851 input stream, such as at commas and equals. You can always tell
1852 perltidy to ignore old breakpoints with -iob.
1854 - Fixed glitch in which a terminal closing hash brace followed by semicolon
1855 was not outdented back to the leading line depth like other closing
1856 tokens. Thanks to Keith Neargarder for noting this.
1859 my ( $pre, $post ) = @{
1861 "pp_anonlist" => [ "[", "]" ],
1862 "pp_anonhash" => [ "{", "}" ]
1863 }->{ $kid->ppaddr }
1867 my ( $pre, $post ) = @{
1869 "pp_anonlist" => [ "[", "]" ],
1870 "pp_anonhash" => [ "{", "}" ]
1871 }->{ $kid->ppaddr }
1874 - Removed extra indentation given to trailing 'if' and 'unless' clauses
1875 without parentheses because this occasionally produced undesirable
1876 results. This only applies where parens are not used after the if or
1881 unless my ( $who, $actions ) =
1882 $clause =~ /^($who_re)((?:$action_re)+)$/o;
1886 unless my ( $who, $actions ) =
1887 $clause =~ /^($who_re)((?:$action_re)+)$/o;
1892 <pre><code>- Updated perltidy to handle all quote modifiers defined for perl 5 version 16.
1894 - Side comment text in perltidyrc configuration files must now begin with
1895 at least one space before the #. Thus:
1898 -l=78 # Max line width is 78 cols
1900 -l=78# Max line width is 78 cols
1902 This is probably true of almost all existing perltidyrc files,
1903 but if you get an error message about bad parameters
1904 involving a '#' the first time you run this version, please check the side
1905 comments in your perltidyrc file, and add a space before the # if necessary.
1906 You can quickly see the contents your perltidyrc file, if any, with the
1911 The reason for this change is that some parameters naturally involve
1912 the # symbol, and this can get interpreted as a side comment unless the
1913 parameter is quoted. For example, to define -sphb=# it used to be necessary
1916 to keep the # from becoming part of a comment. This was causing
1917 trouble for new users. Now it can also be written without quotes:
1920 - Fixed bug in processing some .perltidyrc files containing parameters with
1921 an opening brace character, '{'. For example the following was
1922 incorrectly processed:
1923 --static-block-comment-prefix="^#{2,}[^\s#]"
1926 - Added flag -boa (--break-at-old-attribute-breakpoints) which retains
1927 any existing line breaks at attribute separation ':'. This is now the
1928 default, use -nboa to deactivate. Thanks to Daphne Phister for the patch.
1929 For example, given the following code, the line breaks at the ':'s will be
1935 : Get('Name' => 'foo') : Set('Name');
1937 whereas the previous version would have output a single line. If
1938 the attributes are on a single line then they will remain on a single line.
1940 - Added new flags --blank-lines-before-subs=n (-blbs=n) and
1941 --blank-lines-before-packages=n (-blbp=n) to put n blank lines before
1942 subs and packages. The old flag -bbs is now equivalent to -blbs=1 -blbp=1.
1943 and -nbbs is equivalent to -blbs=0 -blbp=0. Requested by M. Schwern and
1946 - Added feature -nsak='*' meaning no space between any keyword and opening
1947 paren. This avoids listing entering a long list of keywords. Requested
1950 - Added option to delete a backup of original file with in-place-modify (-b)
1951 if there were no errors. This can be requested with the flag -bext='/'.
1952 See documentation for details. Requested by M. Schwern and others.
1954 - Fixed bug where the module postfilter parameter was not applied when -b
1955 flag was used. This was discovered during testing.
1957 - Fixed in-place-modify (-b) to work with symbolic links to source files.
1958 Thanks to Ted Johnson.
1960 - Fixed bug where the Perl::Tidy module did not allow -b to be used
1963 - No extra blank line is added before a comment which follows
1964 a short line ending in an opening token, for example like this:
1968 # unless we follow a blank or comment line
1969 $last_line_leading_type !~ /^[#b]$/
1974 # unless we follow a blank or comment line
1975 $last_line_leading_type !~ /^[#b]$/
1978 The blank is not needed for readability in these cases because there
1979 already is already space above the comment. If a blank already
1980 exists there it will not be removed, so this change should not
1981 change code which has previously been formatted with perltidy.
1982 Thanks to R.W.Stauner.
1984 - Likewise, no extra blank line is added above a comment consisting of a
1985 single #, since nothing is gained in readability.
1987 - Fixed error in which a blank line was removed after a #>>> directive.
1988 Thanks to Ricky Morse.
1990 - Unnecessary semicolons after given/when/default blocks are now removed.
1992 - Fixed bug where an unwanted blank line could be added before
1993 pod text in __DATA__ or __END__ section. Thanks to jidani.
1995 - Changed exit flags from 1 to 0 to indicate success for -help, -version,
1996 and all -dump commands. Also added -? as another way to dump the help.
1997 Requested by Keith Neargarder.
1999 - Fixed bug where .ERR and .LOG files were not written except for -it=2 or more
2001 - Fixed bug where trailing blank lines at the end of a file were dropped when
2004 - Fixed bug where a line occasionally ended with an extra space. This reduces
2005 rhe number of instances where a second iteration gives a result different
2008 - Updated documentation to note that the Tidy.pm module <stderr> parameter may
2009 not be a reference to SCALAR or ARRAY; it must be a file.
2011 - Syntax check with perl now work when the Tidy.pm module is processing
2012 references to arrays and strings. Thanks to Charles Alderman.
2014 - Zero-length files are no longer processed due to concerns for data loss
2015 due to side effects in some scenarios.
2017 - block labels, if any, are now included in closing side comment text
2018 when the -csc flag is used. Suggested by Aaron. For example,
2019 the label L102 in the following block is now included in the -csc text:
2021 L102: for my $i ( 1 .. 10 ) {
2023 } ## end L102: for my $i ( 1 .. 10 )
2028 <pre><code>- added new flag -it=n or --iterations=n
2029 This flag causes perltidy to do n complete iterations.
2030 For most purposes the default of n=1 should be satisfactory. However n=2
2031 can be useful when a major style change is being made, or when code is being
2032 beautified on check-in to a source code control system. The run time will be
2033 approximately proportional to n, and it should seldom be necessary to use a
2034 value greater than n=2. Thanks to Jonathan Swartz
2036 - A configuration file pathname begins with three dots, e.g.
2037 ".../.perltidyrc", indicates that the file should be searched for starting
2038 in the current directory and working upwards. This makes it easier to have
2039 multiple projects each with their own .perltidyrc in their root directories.
2040 Thanks to Jonathan Swartz for this patch.
2042 - Added flag --notidy which disables all formatting and causes the input to be
2043 copied unchanged. This can be useful in conjunction with hierarchical
2044 F<.perltidyrc> files to prevent unwanted tidying.
2045 Thanks to Jonathan Swartz for this patch.
2047 - Added prefilters and postfilters in the call to the Tidy.pm module.
2048 Prefilters and postfilters. The prefilter is a code reference that
2049 will be applied to the source before tidying, and the postfilter
2050 is a code reference to the result before outputting.
2052 Thanks to Jonathan Swartz for this patch. He writes:
2053 This is useful for all manner of customizations. For example, I use
2054 it to convert the 'method' keyword to 'sub' so that perltidy will work for
2055 Method::Signature::Simple code:
2057 Perl::Tidy::perltidy(
2058 prefilter => sub { $_ = $_[0]; s/^method (.*)/sub $1 \#__METHOD/gm; return $_ },
2059 postfilter => sub { $_ = $_[0]; s/^sub (.*?)\s* \#__METHOD/method $1/gm; return $_ }
2062 - The starting indentation level of sections of code entabbed with -et=n
2063 is correctly guessed if it was also produced with the same -et=n flag. This
2064 keeps the indentation stable on repeated formatting passes within an editor.
2065 Thanks to Sam Kington and Glenn.
2067 - Functions with prototype '&' had a space between the function and opening
2068 peren. This space now only occurs if the flag --space-function-paren (-sfp)
2069 is set. Thanks to Zrajm Akfohg.
2071 - Patch to never put spaces around a bare word in braces beginning with ^ as in:
2072 my $before = ${^PREMATCH};
2073 even if requested with the -bt=0 flag because any spaces cause a syntax error in perl.
2074 Thanks to Fabrice Dulanoy.
2079 <pre><code>- Allow configuration file to be 'perltidy.ini' for Windows systems.
2080 i.e. C:\Documents and Settings\User\perltidy.ini
2081 and added documentation for setting configuation file under Windows in man
2082 page. Thanks to Stuart Clark.
2084 - Corrected problem of unwanted semicolons in hash ref within given/when code.
2085 Thanks to Nelo Onyiah.
2087 - added new flag -cscb or --closing-side-comments-balanced
2088 When using closing-side-comments, and the closing-side-comment-maximum-text
2089 limit is exceeded, then the comment text must be truncated. Previous
2090 versions of perltidy terminate with three dots, and this can still be
2091 achieved with -ncscb:
2093 perltidy -csc -ncscb
2095 } ## end foreach my $foo (sort { $b cmp $a ...
2097 However this causes a problem with older editors which cannot recognize
2098 comments or are not configured to doso because they cannot "bounce" around in
2099 the text correctly. The B<-cscb> flag tries to help them by
2100 appending appropriate terminal balancing structure:
2104 } ## end foreach my $foo (sort { $b cmp $a ... })
2106 Since there is much to be gained and little to be lost by doing this,
2107 the default is B<-cscb>. Use B<-ncscb> if you do not want this.
2109 Thanks to Daniel Becker for suggesting this option.
2111 - After an isolated closing eval block the continuation indentation will be
2112 removed so that the braces line up more like other blocks. Thanks to Yves Orton.
2131 -A new flag -asbl (or --opening-anonymous-sub-brace-on-new-line) has
2132 been added to put the opening brace of anonymous sub's on a new line,
2133 as in the following snippet:
2138 return $arg->(@_);
2141 This was not possible before because the -sbl flag only applies to named
2142 subs. Thanks to Benjamin Krupp.
2144 -Fix tokenization bug with the following snippet
2145 print 'hi' if { x => 1, }->{x};
2146 which resulted in a semicolon being added after the comma. The workaround
2147 was to use -nasc, but this is no longer necessary. Thanks to Brian Duggan.
2149 -Fixed problem in which an incorrect error message could be triggered
2150 by the (unusual) combination of parameters -lp -i=0 -l=2 -ci=0 for
2151 example. Thanks to Richard Jelinek.
2153 -A new flag --keep-old-blank-lines=n has been added to
2154 give more control over the treatment of old blank lines in
2155 a script. The manual has been revised to discuss the new
2156 flag and clarify the treatment of old blank lines. Thanks
2162 <pre><code>-Improved support for perl 5.10: New quote modifier 'p', new block type UNITCHECK,
2163 new keyword break, improved formatting of given/when.
2165 -Corrected tokenization bug of something like $var{-q}.
2167 -Numerous minor formatting improvements.
2169 -Corrected list of operators controlled by -baao -bbao to include
2170 . : ? && || and or err xor
2172 -Corrected very minor error in log file involving incorrect comment
2173 regarding need for upper case of labels.
2175 -Fixed problem where perltidy could run for a very long time
2176 when given certain non-perl text files.
2178 -Line breaks in un-parenthesized lists now try to follow
2179 line breaks in the input file rather than trying to fill
2180 lines. This usually works better, but if this causes
2181 trouble you can use -iob to ignore any old line breaks.
2182 Example for the following input snippet:
2185 "conformability (Not the same dimension)\n",
2186 "\t", $have, " is ", text_unit($hu), "\n",
2187 "\t", $want, " is ", text_unit($wu), "\n",
2191 print "conformability (Not the same dimension)\n", "\t", $have, " is ",
2192 text_unit($hu), "\n", "\t", $want, " is ", text_unit($wu), "\n",;
2195 print "conformability (Not the same dimension)\n",
2196 "\t", $have, " is ", text_unit($hu), "\n",
2197 "\t", $want, " is ", text_unit($wu), "\n",
2203 <pre><code>-Added -fpsc option (--fixed-position-side-comment). Thanks to Ueli Hugenschmidt.
2204 For example -fpsc=40 tells perltidy to put side comments in column 40
2207 -Added -bbao and -baao options (--break-before-all-operators and
2208 --break-after-all-operators) to simplify command lines and configuration
2209 files. These define an initial preference for breaking at operators which can
2210 be modified with -wba and -wbb flags. For example to break before all operators
2211 except an = one could use --bbao -wba='=' rather than listing every
2212 single perl operator (except =) on a -wbb flag.
2214 -Added -kis option (--keep-interior-semicolons). Use the B<-kis> flag
2215 to prevent breaking at a semicolon if there was no break there in the
2216 input file. To illustrate, consider the following input lines:
2218 dbmclose(%verb_delim); undef %verb_delim;
2219 dbmclose(%expanded); undef %expanded;
2220 dbmclose(%global); undef %global;
2222 Normally these would be broken into six lines, but
2223 perltidy -kis gives:
2225 dbmclose(%verb_delim); undef %verb_delim;
2226 dbmclose(%expanded); undef %expanded;
2227 dbmclose(%global); undef %global;
2229 -Improved formatting of complex ternary statements, with indentation
2230 of nested statements.
2232 return defined( $cw->{Selected} )
2234 ? @{ $cw->{Selected} }
2235 : $cw->{Selected}[0]
2239 return defined( $cw->{Selected} )
2241 ? @{ $cw->{Selected} }
2242 : $cw->{Selected}[0]
2245 -Text following un-parenthesized if/unless/while/until statements get a
2246 full level of indentation. Suggested by Jeff Armstrong and others.
2248 return $ship->chargeWeapons("phaser-canon")
2249 if $encounter->description eq 'klingon'
2250 and $ship->firepower >= $encounter->firepower
2251 and $location->status ne 'neutral';
2253 return $ship->chargeWeapons("phaser-canon")
2254 if $encounter->description eq 'klingon'
2255 and $ship->firepower >= $encounter->firepower
2256 and $location->status ne 'neutral';
2261 <pre><code>-Fixed bug where #line directives were being indented. Thanks to
2267 <pre><code>-Fixed problem where an extra blank line was added after an =cut when either
2268 (a) the =cut started (not stopped) a POD section, or (b) -mbl > 1.
2269 Thanks to J. Robert Ray and Bill Moseley.
2274 <pre><code>-ole (--output-line-ending) and -ple (--preserve-line-endings) should
2275 now work on all systems rather than just unix systems. Thanks to Dan
2278 -Fixed problem of a warning issued for multiple subs for BEGIN subs
2279 and other control subs. Thanks to Heiko Eissfeldt.
2281 -Fixed problem where no space was introduced between a keyword or
2282 bareword and a colon, such as:
2284 ( ref($result) eq 'HASH' && !%$result ) ? undef: $result;
2288 -Added a utility program 'break_long_quotes.pl' to the examples directory of
2289 the distribution. It breaks long quoted strings into a chain of concatenated
2290 sub strings no longer than a selected length. Suggested by Michael Renner as
2291 a perltidy feature but was judged to be best done in a separate program.
2293 -Updated docs to remove extra < and >= from list of tokens
2294 after which breaks are made by default. Thanks to Bob Kleemann.
2296 -Removed improper uses of $_ to avoid conflicts with external calls, giving
2297 error message similar to:
2298 Modification of a read-only value attempted at
2299 /usr/share/perl5/Perl/Tidy.pm line 6907.
2300 Thanks to Michael Renner.
2302 -Fixed problem when errorfile was not a plain filename or filehandle
2303 in a call to Tidy.pm. The call
2304 perltidy(source => \$input, destination => \$output, errorfile => \$err);
2305 gave the following error message:
2306 Not a GLOB reference at /usr/share/perl5/Perl/Tidy.pm line 3827.
2307 Thanks to Michael Renner and Phillipe Bruhat.
2309 -Fixed problem where -sot would not stack an opening token followed by
2310 a side comment. Thanks to Jens Schicke.
2312 -improved breakpoints in complex math and other long statements. Example:
2315 log($n) + 0.577215664901532 + ( 1 / ( 2 * $n ) ) -
2316 ( 1 / ( 12 * ( $n**2 ) ) ) + ( 1 / ( 120 * ( $n**4 ) ) );
2319 log($n) + 0.577215664901532 +
2320 ( 1 / ( 2 * $n ) ) -
2321 ( 1 / ( 12 * ( $n**2 ) ) ) +
2322 ( 1 / ( 120 * ( $n**4 ) ) );
2324 -more robust vertical alignment of complex terminal else blocks and ternary
2330 <pre><code>-Eliminated bug where a here-doc invoked through an 'e' modifier on a pattern
2331 replacement text was not recognized. The tokenizer now recursively scans
2332 replacement text (but does not reformat it).
2334 -improved vertical alignment of terminal else blocks and ternary statements.
2335 Thanks to Chris for the suggestion.
2338 if ( IsBitmap() ) { return GetBitmap(); }
2339 elsif ( IsFiles() ) { return GetFiles(); }
2340 else { return GetText(); }
2343 if ( IsBitmap() ) { return GetBitmap(); }
2344 elsif ( IsFiles() ) { return GetFiles(); }
2345 else { return GetText(); }
2349 $opts{"t"} ? 'title'
2350 : $opts{"s"} ? 'subject'
2351 : $opts{"a"} ? 'author'
2356 $opts{"t"} ? 'title'
2357 : $opts{"s"} ? 'subject'
2358 : $opts{"a"} ? 'author'
2361 -improved indentation of try/catch blocks and other externally defined
2362 functions accepting a block argument. Thanks to jae.
2364 -Added support for Perl 5.10 features say and smartmatch.
2366 -Added flag -pbp (--perl-best-practices) as an abbreviation for parameters
2367 suggested in Damian Conway's "Perl Best Practices". -pbp is the same as:
2369 -l=78 -i=4 -ci=4 -st -se -vt=2 -cti=0 -pt=1 -bt=1 -sbt=1 -bbt=1 -nsfs -nolq
2370 -wbb="% + - * / x != == >= <= =~ !~ < > | & >= < =
2371 **= += *= &= <<= &&= -= /= |= >>= ||= .= %= ^= x="
2373 Please note that the -st here restricts input to standard input; use
2374 -nst if necessary to override.
2376 -Eliminated some needless breaks at equals signs in -lp indentation.
2380 Math::Complex->make(LEFT + $x * (RIGHT - LEFT) / SIZE,
2381 TOP + $y * (BOTTOM - TOP) / SIZE);
2383 $c = Math::Complex->make(LEFT + $x * (RIGHT - LEFT) / SIZE,
2384 TOP + $y * (BOTTOM - TOP) / SIZE);
2386 A break at an equals is sometimes useful for preventing complex statements
2387 from hitting the line length limit. The decision to do this was
2388 over-eager in some cases and has been improved. Thanks to Royce Reece.
2390 -qw quotes contained in braces, square brackets, and parens are being
2391 treated more like those containers as far as stacking of tokens. Also
2392 stack of closing tokens ending ');' will outdent to where the ');' would
2393 have outdented if the closing stack is matched with a similar opening stack.
2395 OLD: perltidy -soc -sct
2396 __PACKAGE__->load_components(
2402 NEW: perltidy -soc -sct
2403 __PACKAGE__->load_components( qw(
2407 Thanks to Aran Deltac
2409 -Eliminated some undesirable or marginally desirable vertical alignments.
2410 These include terminal colons, opening braces, and equals, and particularly
2411 when just two lines would be aligned.
2414 my $accurate_timestamps = $Stamps{lnk};
2418 my $accurate_timestamps = $Stamps{lnk};
2421 -Corrected a problem with -mangle in which a space would be removed
2422 between a keyword and variable beginning with ::.
2427 <pre><code>-Attribute argument lists are now correctly treated as quoted strings
2428 and not formatted. This is the most important update in this version.
2429 Thanks to Borris Zentner, Greg Ferguson, Steve Kirkup.
2431 -Updated to recognize the defined or operator, //, to be released in Perl 10.
2432 Thanks to Sebastien Aperghis-Tramoni.
2434 -A useful utility perltidyrc_dump.pl is included in the examples section. It
2435 will read any perltidyrc file and write it back out in a standard format
2436 (though comments are lost).
2438 -Added option to have perltidy read and return a hash with the contents of a
2439 perltidyrc file. This may be used by Leif Eriksen's tidyview code. This
2440 feature is used by the demonstration program 'perltidyrc_dump.pl' in the
2443 -Improved error checking in perltidyrc files. Unknown bare words were not
2446 -The --dump-options parameter now dumps parameters in the format required by a
2449 -V-Strings with underscores are now recognized.
2450 For example: $v = v1.2_3;
2452 -cti=3 option added which gives one extra indentation level to closing
2453 tokens always. This provides more predictable closing token placement
2454 than cti=2. If you are using cti=2 you might want to try cti=3.
2456 -To identify all left-adjusted comments as static block comments, use C<-sbcp='^#'>.
2458 -New parameters -fs, -fsb, -fse added to allow sections of code between #<<<
2459 and #>>> to be passed through verbatim. This is enabled by default and turned
2460 off by -nfs. Flags -fsb and -fse allow other beginning and ending markers.
2461 Thanks to Wolfgang Werner and Marion Berryman for suggesting this.
2463 -added flag -skp to put a space between all Perl keywords and following paren.
2464 The default is to only do this for certain keywords. Suggested by
2467 -added flag -sfp to put a space between a function name and following paren.
2468 The default is not to do this. Suggested by H.Merijn Brand.
2470 -Added patch to avoid breaking GetOpt::Long::Configure set by calling program.
2471 Thanks to Philippe Bruhat.
2473 -An error was fixed in which certain parameters in a .perltidyrc file given
2474 without the equals sign were not recognized. That is,
2475 '--brace-tightness 0' gave an error but '--brace-tightness=0' worked
2476 ok. Thanks to Zac Hansen.
2478 -An error preventing the -nwrs flag from working was corrected. Thanks to
2481 -Corrected some alignment problems with entab option.
2483 -A bug with the combination of -lp and -extrude was fixed (though this
2484 combination doesn't really make sense). The bug was that a line with
2485 a single zero would be dropped. Thanks to Cameron Hayne.
2487 -Updated Windows detection code to avoid an undefined variable.
2488 Thanks to Joe Yates and Russ Jones.
2490 -Improved formatting for short trailing statements following a closing paren.
2491 Thanks to Joe Matarazzo.
2493 -The handling of the -icb (indent closing block braces) flag has been changed
2494 slightly to provide more consistent and predictable formatting of complex
2495 structures. Instead of giving a closing block brace the indentation of the
2496 previous line, it is now given one extra indentation level. The two methods
2497 give the same result if the previous line was a complete statement, as in this
2506 The change also fixes a problem with empty blocks such as:
2516 -A problem with -icb was fixed in which a closing brace was misplaced when
2517 it followed a quote which spanned multiple lines.
2519 -Some improved breakpoints for -wba='&& || and or'
2521 -Fixed problem with misaligned cuddled else in complex statements
2522 when the -bar flag was also used. Thanks to Alex and Royce Reese.
2524 -Corrected documentation to show that --outdent-long-comments is the default.
2525 Thanks to Mario Lia.
2527 -New flag -otr (opening-token-right) is similar to -bar (braces-always-right)
2528 but applies to non-structural opening tokens.
2530 -new flags -sot (stack-opening-token), -sct (stack-closing-token).
2536 <pre><code>-The default has been changed to not do syntax checking with perl.
2537 Use -syn if you want it. Perltidy is very robust now, and the -syn
2538 flag now causes more problems than it's worth because of BEGIN blocks
2539 (which get executed with perl -c). For example, perltidy will never
2540 return when trying to beautify this code if -syn is used:
2542 BEGIN { 1 while { }; }
2544 Although this is an obvious error, perltidy is often run on untested
2545 code which is more likely to have this sort of problem. A more subtle
2548 BEGIN { use FindBin; }
2550 which may hang on some systems using -syn if a shared file system is
2553 -Changed style -gnu to use -cti=1 instead of -cti=2 (see next item).
2554 In most cases it looks better. To recover the previous format, use
2557 -Added flags -cti=n for finer control of closing token indentation.
2558 -cti = 0 no extra indentation (default; same as -nicp)
2559 -cti = 1 enough indentation so that the closing token
2560 aligns with its opening token.
2561 -cti = 2 one extra indentation level if the line has the form
2562 ); ]; or }; (same as -icp).
2564 The new option -cti=1 works well with -lp:
2568 # perltidy -lp -cti=1
2570 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
2571 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
2574 # perltidy -lp -cti=2
2576 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
2577 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
2579 This is backwards compatible with -icp. See revised manual for
2580 details. Suggested by Mike Pennington.
2582 -Added flag '--preserve-line-endings' or '-ple' to cause the output
2583 line ending to be the same as in the input file, for unix, dos,
2584 or mac line endings. Only works under unix. Suggested by
2587 -Added flag '--output-line-ending=s' or '-ole=s' where s=dos or win,
2588 unix, or mac. Only works under unix.
2590 -Files with Mac line endings should now be handled properly under unix
2591 and dos without being passed through a converter.
2593 -You may now include 'and', 'or', and 'xor' in the list following
2594 '--want-break-after' to get line breaks after those keywords rather than
2595 before them. Suggested by Rainer Hochschild.
2597 -Corrected problem with command line option for -vtc=n and -vt=n. The
2598 equals sign was being eaten up by the Windows shell so perltidy didn't
2604 <pre><code>-Corrected cause of warning message with recent versions of Perl:
2605 "Possible precedence problem on bitwise & operator at ..."
2606 Thanks to Jim Files.
2608 -fixed bug with -html with '=for pod2html' sections, in which code/pod
2609 output order was incorrect. Thanks to Tassilo von Parseval.
2611 -fixed bug when the -html flag is used, in which the following error
2612 message, plus others, appear:
2613 did not see <body> in pod2html output
2614 This was caused by a change in the format of html output by pod2html
2615 VERSION 1.04 (included with perl 5.8). Thanks to Tassilo von Parseval.
2617 -Fixed bug where an __END__ statement would be mistaken for a label
2618 if it is immediately followed by a line with a leading colon. Thanks
2621 -Implemented guessing logic for brace types when it is ambiguous. This
2622 has been on the TODO list a long time. Thanks to Boris Zentner for
2625 -Long options may now be negated either as '--nolong-option'
2626 or '--no-long-option'. Thanks to Philip Newton for the suggestion.
2628 -added flag --html-entities or -hent which controls the use of
2629 Html::Entities for html formatting. Use --nohtml-entities or -nhent to
2630 prevent the use of Html::Entities to encode special symbols. The
2631 default is -hent. Html::Entities when formatting perl text to escape
2632 special symbols. This may or may not be the right thing to do,
2633 depending on browser/language combinations. Thanks to Burak Gursoy for
2636 -Bareword strings with leading '-', like, '-foo' now count as 1 token
2637 for horizontal tightness. This way $a{'-foo'}, $a{foo}, and $a{-foo}
2638 are now all treated similarly. Thus, by default, OLD: $a{ -foo } will
2639 now be NEW: $a{-foo}. Suggested by Mark Olesen.
2641 -added 2 new flags to control spaces between keywords and opening parens:
2642 -sak=s or --space-after-keyword=s, and
2643 -nsak=s or --nospace-after-keyword=s, where 's' is a list of keywords.
2645 The new default list of keywords which get a space is:
2647 "my local our and or eq ne if else elsif until unless while for foreach
2648 return switch case given when"
2650 Use -sak=s and -nsak=s to add and remove keywords from this list,
2653 Explanation: Stephen Hildrey noted that perltidy was being inconsistent
2654 in placing spaces between keywords and opening parens, and sent a patch
2655 to give user control over this. The above list was selected as being
2656 a reasonable default keyword list. Previously, perltidy
2657 had a hardwired list which also included these keywords:
2659 push pop shift unshift join split die
2661 but did not have 'our'. Example: if you prefer to make perltidy behave
2662 exactly as before, you can include the following two lines in your
2665 -sak="push pop local shift unshift join split die"
2668 -Corrected html error in .toc file when -frm -html is used (extra ");
2669 browsers were tolerant of it.
2671 -Improved alignment of chains of binary and ?/: operators. Example:
2685 -improved breakpoint choices involving '->'
2687 -Corrected tokenization of things like ${#}. For example,
2688 ${#} is valid, but ${# } is a syntax error.
2690 -Corrected minor tokenization errors with indirect object notation.
2691 For example, 'new A::()' works now.
2693 -Minor tokenization improvements; all perl code distributed with perl 5.8
2694 seems to be parsed correctly except for one instance (lextest.t)
2700 <pre><code>-Implemented scalar attributes. Thanks to Sean Tobin for noting this.
2702 -Fixed glitch introduced in previous release where -pre option
2703 was not outputting a leading html <pre> tag.
2705 -Numerous minor improvements in vertical alignment, including the following:
2707 -Improved alignment of opening braces in many cases. Needed for improved
2708 switch/case formatting, and also suggested by Mark Olesen for sort/map/grep
2709 formatting. For example:
2714 sort { $a->[1] <=> $b->[1] }
2715 map { [ $_, -M ] } @filenames;
2720 sort { $a->[1] <=> $b->[1] }
2721 map { [ $_, -M ] } @filenames;
2723 -Eliminated alignments across unrelated statements. Example:
2725 $borrowerinfo->configure( -state => 'disabled' );
2726 $borrowerinfo->grid( -col => 1, -row => 0, -sticky => 'w' );
2729 $borrowerinfo->configure( -state => 'disabled' );
2730 $borrowerinfo->grid( -col => 1, -row => 0, -sticky => 'w' );
2732 Thanks to Mark Olesen for suggesting this.
2734 -Improved alignement of '='s in certain cases.
2735 Thanks to Norbert Gruener for sending an example.
2737 -Outdent-long-comments (-olc) has been re-instated as a default, since
2738 it works much better now. Use -nolc if you want to prevent it.
2740 -Added check for 'perltidy file.pl -o file.pl', which causes file.pl
2741 to be lost. (The -b option should be used instead). Thanks to mreister
2742 for reporting this problem.
2747 <pre><code>-Switch/case or given/when syntax is now recognized. Its vertical alignment
2748 is not great yet, but it parses ok. The words 'switch', 'case', 'given',
2749 and 'when' are now treated as keywords. If this causes trouble with older
2750 code, we could introduce a switch to deactivate it. Thanks to Stan Brown
2751 and Jochen Schneider for recommending this.
2753 -Corrected error parsing sub attributes with call parameters.
2754 Thanks to Marc Kerr for catching this.
2756 -Sub prototypes no longer need to be on the same line as sub names.
2758 -a new flag -frm or --frames will cause html output to be in a
2759 frame, with table of contents in the left panel and formatted source
2760 in the right panel. Try 'perltidy -html -frm somemodule.pm' for example.
2762 -The new default for -html formatting is to pass the pod through Pod::Html.
2763 The result is syntax colored code within your pod documents. This can be
2764 deactivated with -npod. Thanks to those who have written to discuss this,
2765 particularly Mark Olesen and Hugh Myers.
2767 -the -olc (--outdent-long-comments) option works much better. It now outdents
2768 groups of consecutive comments together, and by just the amount needed to
2769 avoid having any one line exceeding the maximum line length.
2771 -block comments are now trimmed of trailing whitespace.
2773 -if a directory specified with -opath does not exist, it will be created.
2775 -a table of contents to packages and subs is output when -html is used.
2776 Use -ntoc to prevent this.
2778 -fixed an unusual bug in which a 'for' statement following a 'format'
2779 statement was not correctly tokenized. Thanks to Boris Zentner for
2782 -Tidy.pm is no longer dependent on modules IO::Scalar and IO::ScalarArray.
2783 There were some speed issues. Suggested by Joerg Walter.
2785 -The treatment of quoted wildcards (file globs) is now system-independent.
2788 perltidy 'b*x.p[lm]'
2790 would match box.pl, box.pm, brinx.pm under any operating system. Of
2791 course, anything unquoted will be subject to expansion by any shell.
2793 -default color for keywords under -html changed from
2794 SaddleBrown (#8B4513) to magenta4 (#8B008B).
2796 -fixed an arg parsing glitch in which something like:
2798 would trigger the help message and exit, rather than operate on the
2804 <pre><code>-New option '-b' or '--backup-and-modify-in-place' will cause perltidy to
2805 overwrite the original file with the tidied output file. The original
2806 file will be saved with a '.bak' extension (which can be changed with
2807 -bext=s). Thanks to Rudi Farkas for the suggestion.
2809 -An index to all subs is included at the top of -html output, unless
2810 only the <pre> section is written.
2812 -Anchor lines of the form <a name="mysub"></a> are now inserted at key points
2813 in html output, such as before sub definitions, for the convenience of
2814 postprocessing scripts. Suggested by Howard Owen.
2816 -The cuddled-else (-ce) flag now also makes cuddled continues, like
2819 while ( ( $pack, $file, $line ) = caller( $i++ ) ) {
2825 Suggested by Simon Perreault.
2827 -Fixed bug in which an extra blank line was added before an =head or
2828 similar pod line after an __END__ or __DATA__ line each time
2829 perltidy was run. Also, an extra blank was being added after
2830 a terminal =cut. Thanks to Mike Birdsall for reporting this.
2835 <pre><code>-Fixed bug in which space was inserted in a hyphenated hash key:
2836 my $val = $myhash{USER-NAME};
2838 my $val = $myhash{USER -NAME};
2839 Thanks to an anonymous bug reporter at sourceforge.
2841 -Fixed problem with the '-io' ('--indent-only') where all lines
2842 were double spaced. Thanks to Nick Andrew for reporting this bug.
2844 -Fixed tokenization error in which something like '-e1' was
2847 -Corrected a rare problem involving older perl versions, in which
2848 a line break before a bareword caused problems with 'use strict'.
2849 Thanks to Wolfgang Weisselberg for noting this.
2851 -More syntax error checking added.
2853 -Outdenting labels (-ola) has been made the default, in order to follow the
2854 perlstyle guidelines better. It's probably a good idea in general, but
2855 if you do not want this, use -nola in your .perltidyrc file.
2857 -Updated rules for padding logical expressions to include more cases.
2858 Thanks to Wolfgang Weisselberg for helpful discussions.
2860 -Added new flag -osbc (--outdent-static-block-comments) which will
2861 outdent static block comments by 2 spaces (or whatever -ci equals).
2862 Requested by Jon Robison.
2867 <pre><code>-Corrected a bug, introduced in the previous release, in which some
2868 closing side comments (-csc) could have incorrect text. This is
2869 annoying but will be correct the next time perltidy is run with -csc.
2871 -Fixed bug where whitespace was being removed between 'Bar' and '()'
2872 in a use statement like:
2876 -Whenever possible, if a logical expression is broken with leading
2877 '&&', '||', 'and', or 'or', then the leading line will be padded
2878 with additional space to produce alignment. This has been on the
2879 todo list for a long time; thanks to Frank Steinhauer for reminding
2880 me to do it. Notice the first line after the open parens here:
2884 !param("rules.to.$linecount")
2885 && !param("rules.from.$linecount")
2886 && !param("rules.subject.$linecount")
2888 param("rules.fieldname.$linecount")
2889 && param("rules.fieldval.$linecount")
2891 && !param("rules.size.$linecount")
2892 && !param("rules.custom.$linecount")
2897 !param("rules.to.$linecount")
2898 && !param("rules.from.$linecount")
2899 && !param("rules.subject.$linecount")
2901 param("rules.fieldname.$linecount")
2902 && param("rules.fieldval.$linecount")
2904 && !param("rules.size.$linecount")
2905 && !param("rules.custom.$linecount")
2911 <pre><code>-Corrected a mistokenization of variables for a package with a name
2912 equal to a perl keyword. For example:
2916 sub qx{print "Hello from my::qx\n";}
2918 In this case, the leading 'my' was mistokenized as a keyword, and a
2919 space was being place between 'my' and '::'. This has been
2920 corrected. Thanks to Martin Sluka for discovering this.
2922 -A new flag -bol (--break-at-old-logic-breakpoints)
2923 has been added to control whether containers with logical expressions
2924 should be broken open. This is the default.
2926 -A new flag -bok (--break-at-old-keyword-breakpoints)
2927 has been added to follow breaks at old keywords which return lists,
2928 such as sort and map. This is the default.
2930 -A new flag -bot (--break-at-old-trinary-breakpoints) has been added to
2931 follow breaks at trinary (conditional) operators. This is the default.
2933 -A new flag -cab=n has been added to control breaks at commas after
2934 '=>' tokens. The default is n=1, meaning break unless this breaks
2935 open an existing on-line container.
2937 -A new flag -boc has been added to allow existing list formatting
2938 to be retained. (--break-at-old-comma-breakpoints). See updated manual.
2940 -A new flag -iob (--ignore-old-breakpoints) has been added to
2941 prevent the locations of old breakpoints from influencing the output
2944 -Corrected problem where nested parentheses were not getting full
2945 indentation. This has been on the todo list for some time; thanks
2946 to Axel Rose for a snippet demonstrating this issue.
2948 OLD: inner list is not indented
2949 $this->sendnumeric(
2952 $ret->name, $user->username, $user->host,
2953 $user->server->name, $user->nick, "H"
2958 $this->sendnumeric(
2961 $ret->name, $user->username, $user->host,
2962 $user->server->name, $user->nick, "H"
2966 -Code cleaned up by removing the following unused, undocumented flags.
2967 They should not be in any .perltidyrc files because they were just
2968 experimental flags which were never documented. Most of them placed
2969 artificial limits on spaces, and Wolfgang Weisselberg convinced me that
2970 most of them they do more harm than good by causing unexpected results.
2972 --maximum-continuation-indentation (-mci)
2973 --maximum-whitespace-columns
2974 --maximum-space-to-comment (-xsc)
2975 --big-space-jump (-bsj)
2977 -Pod file 'perltidy.pod' has been appended to the script 'perltidy', and
2978 Tidy.pod has been append to the module 'Tidy.pm'. Older MakeMaker's
2979 were having trouble.
2981 -A new flag -isbc has been added for more control on comments. This flag
2982 has the effect that if there is no leading space on the line, then the
2983 comment will not be indented, and otherwise it may be. If both -ibc and
2984 -isbc are set, then -isbc takes priority. Thanks to Frank Steinhauer
2985 for suggesting this.
2987 -A new document 'stylekey.pod' has been created to quickly guide new users
2988 through the maze of perltidy style parameters. An html version is
2989 on the perltidy web page. Take a look! It should be very helpful.
2991 -Parameters for controlling 'vertical tightness' have been added:
2992 -vt and -vtc are the main controls, but finer control is provided
2993 with -pvt, -pcvt, -bvt, -bcvt, -sbvt, -sbcvt. Block brace vertical
2994 tightness controls have also been added.
2995 See updated manual and also see 'stylekey.pod'. Simple examples:
2997 # perltidy -lp -vt=1 -vtc=1
2998 @month_of_year = ( 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
2999 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec' );
3001 # perltidy -lp -vt=1 -vtc=0
3002 @month_of_year = ( 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
3003 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
3006 -Lists which do not format well in uniform columns are now better
3007 identified and formated.
3010 return $c->create( 'polygon', $x, $y, $x + $ruler_info{'size'},
3011 $y + $ruler_info{'size'}, $x - $ruler_info{'size'},
3012 $y + $ruler_info{'size'} );
3015 return $c->create(
3017 $x + $ruler_info{'size'},
3018 $y + $ruler_info{'size'},
3019 $x - $ruler_info{'size'},
3020 $y + $ruler_info{'size'}
3024 radlablist($f1, pad('Initial', $p), $b->{Init}->get_panel_ref, 'None ',
3025 'None', 'Default', 'Default', 'Simple', 'Simple');
3029 $b->{Init}->get_panel_ref,
3030 'None ', 'None', 'Default', 'Default', 'Simple', 'Simple');
3032 -Corrected problem where an incorrect html filename was generated for
3033 external calls to Tidy.pm module. Fixed incorrect html title when
3034 Tidy.pm is called with IO::Scalar or IO::Array source.
3036 -Output file permissions are now set as follows. An output script file
3037 gets the same permission as the input file, except that owner
3038 read/write permission is added (otherwise, perltidy could not be
3039 rerun). Html output files use system defaults. Previously chmod 0755
3040 was used in all cases. Thanks to Mark Olesen for bringing this up.
3042 -Missing semicolons will not be added in multi-line blocks of type
3043 sort, map, or grep. This brings perltidy into closer agreement
3044 with common practice. Of course, you can still put semicolons
3045 there if you like. Thanks to Simon Perreault for a discussion of this.
3047 -Most instances of extra semicolons are now deleted. This is
3048 particularly important if the -csc option is used. Thanks to Wolfgang
3049 Weisselberg for noting this. For example, the following line
3050 (produced by 'h2xs' :) has an extra semicolon which will now be
3053 BEGIN { plan tests => 1 };
3055 -New parameter -csce (--closing-side-comment-else-flag) can be used
3056 to control what text is appended to 'else' and 'elsif' blocks.
3057 Default is to just add leading 'if' text to an 'else'. See manual.
3059 -The -csc option now labels 'else' blocks with additinal information
3060 from the opening if statement and elsif statements, if space.
3061 Thanks to Wolfgang Weisselberg for suggesting this.
3063 -The -csc option will now remove any old closing side comments
3064 below the line interval threshold. Thanks to Wolfgang Weisselberg for
3067 -The abbreviation feature, which was broken in the previous version,
3068 is now fixed. Thanks to Michael Cartmell for noting this.
3070 -Vertical alignment is now done for '||=' .. somehow this was
3076 <pre><code>-This version uses modules for the first time, and a standard perl
3077 Makefile.PL has been supplied. However, perltidy may still be
3078 installed as a single script, without modules. See INSTALL for
3081 -The man page 'perl2web' has been merged back into the main 'perltidy'
3082 man page to simplify installation. So you may remove that man page
3083 if you have an older installation.
3085 -Added patch from Axel Rose for MacPerl. The patch prompts the user
3086 for command line arguments before calling the module
3087 Perl::Tidy::perltidy.
3089 -Corrected bug with '-bar' which was introduced in the previous
3090 version. A closing block brace was being indented. Thanks to
3091 Alexandros M Manoussakis for reporting this.
3093 -New parameter '--entab-leading-whitespace=n', or '-et=n', has been
3094 added for those who prefer tabs. This behaves different from the
3095 existing '-t' parameter; see updated man page. Suggested by Mark
3098 -New parameter '--perl-syntax-check-flags=s' or '-pcsf=s' can be
3099 used to change the flags passed to perltidy in a syntax check.
3100 See updated man page. Suggested by Mark Olesen.
3102 -New parameter '--output-path=s' or '-opath=s' will cause output
3103 files to be placed in directory s. See updated man page. Thanks for
3104 Mark Olesen for suggesting this.
3106 -New parameter --dump-profile (or -dpro) will dump to
3107 standard output information about the search for a
3108 configuration file, the name of whatever configuration file
3109 is selected, and its contents. This should help debugging
3110 config files, especially on different Windows systems.
3112 -The -w parameter now notes possible errors of the form:
3114 $comment = s/^\s*(\S+)\..*/$1/; # trim whitespace
3116 -Corrections added for a leading ':' and for leaving a leading 'tcsh'
3117 line untouched. Mark Olesen reported that lines of this form were
3118 accepted by perl but not by perltidy:
3120 : # use -*- perl -*-
3121 eval 'exec perl -wS $0 "$@"' # shell should exec 'perl'
3122 unless 1; # but Perl should skip this one
3124 Perl will silently swallow a leading colon on line 1 of a
3125 script, and now perltidy will do likewise. For example,
3126 this is a valid script, provided that it is the first line,
3129 : print "Hello World\n";
3131 Also, perltidy will now mark a first line with leading ':' followed by
3132 '#' as type SYSTEM (just as a #! line), not to be formatted.
3134 -List formatting improved for certain lists with special
3135 initial terms, such as occur with 'printf', 'sprintf',
3136 'push', 'pack', 'join', 'chmod'. The special initial term is
3137 now placed on a line by itself. For example, perltidy -gnu
3141 "C4", hex($SourceAddr[0]),
3142 hex($SourceAddr[1]), hex($SourceAddr[2]),
3148 hex($SourceAddr[0]), hex($SourceAddr[1]),
3149 hex($SourceAddr[2]), hex($SourceAddr[3]));
3153 @{$$self{states}}, '64', '66', '68',
3154 '70', '72', '74', '76',
3155 '78', '80', '82', '84',
3156 '86', '88', '90', '92',
3157 '94', '96', '98', '100',
3164 '64', '66', '68', '70', '72', '74', '76',
3165 '78', '80', '82', '84', '86', '88', '90',
3166 '92', '94', '96', '98', '100', '102', '104'
3169 -Lists of complex items, such as matricies, are now detected
3170 and displayed with just one item per row:
3173 $this->{'CURRENT'}{'gfx'}{'MatrixSkew'} = Text::PDF::API::Matrix->new(
3174 [ 1, tan( deg2rad($a) ), 0 ], [ tan( deg2rad($b) ), 1, 0 ],
3179 $this->{'CURRENT'}{'gfx'}{'MatrixSkew'} = Text::PDF::API::Matrix->new(
3180 [ 1, tan( deg2rad($a) ), 0 ],
3181 [ tan( deg2rad($b) ), 1, 0 ],
3185 -The perl syntax check will be turned off for now when input is from
3186 standard input or standard output. The reason is that this requires
3187 temporary files, which has produced far too many problems during
3188 Windows testing. For example, the POSIX module under Windows XP/2000
3189 creates temporary names in the root directory, to which only the
3190 administrator should have permission to write.
3192 -Merged patch sent by Yves Orton to handle appropriate
3193 configuration file locations for different Windows varieties
3194 (2000, NT, Me, XP, 95, 98).
3196 -Added patch to properly handle a for/foreach loop without
3197 parens around a list represented as a qw. I didn't know this
3198 was possible until Wolfgang Weisselberg pointed it out:
3200 foreach my $key qw\Uno Due Tres Quadro\ {
3204 But Perl will give a syntax error without the $ variable; ie this will
3207 foreach qw\Uno Due Tres Quadro\ {
3211 -Merged Windows version detection code sent by Yves Orton. Perltidy
3212 now automatically turns off syntax checking for Win 9x/ME versions,
3213 and this has solved a lot of robustness problems. These systems
3214 cannot reliably handle backtick operators. See man page for
3217 -Merged VMS filename handling patch sent by Michael Cartmell. (Invalid
3218 output filenames were being created in some cases).
3220 -Numerous minor improvements have been made for -lp style indentation.
3222 -Long C-style 'for' expressions will be broken after each ';'.
3224 'perltidy -gnu' gives:
3227 for ($status = $db->seq($key, $value, R_CURSOR()) ; $status == 0
3228 and $key eq $origkey ; $status = $db->seq($key, $value, R_NEXT()))
3231 for ($status = $db->seq($key, $value, R_CURSOR()) ;
3232 $status == 0 and $key eq $origkey ;
3233 $status = $db->seq($key, $value, R_NEXT()))
3235 -For the -lp option, a single long term within parens
3236 (without commas) now has better alignment. For example,
3240 $self->throw("Must specify a known host, not $location,"
3241 . " possible values ("
3242 . join (",", sort keys %hosts) . ")");
3245 $self->throw("Must specify a known host, not $location,"
3246 . " possible values ("
3247 . join (",", sort keys %hosts) . ")");
3252 <pre><code>-This version is about 20 percent faster than the previous
3253 version as a result of optimization work. The largest gain
3254 came from switching to a dispatch hash table in the
3257 -perltidy -html will check to see if HTML::Entities is
3258 installed, and if so, it will use it to encode unsafe
3261 -Added flag -oext=ext to change the output file extension to
3262 be different from the default ('tdy' or 'html'). For
3265 perltidy -html -oext=htm filename
3267 will produce filename.htm
3269 -Added flag -cscw to issue warnings if a closing side comment would replace
3270 an existing, different side comments. See the man page for details.
3271 Thanks to Peter Masiar for helpful discussions.
3273 -Corrected tokenization error of signed hex/octal/binary numbers. For
3274 example, the first hex number below would have been parsed correctly
3275 but the second one was not:
3276 if ( ( $tmp >= 0x80_00_00 ) || ( $tmp < -0x80_00_00 ) ) { }
3278 -'**=' was incorrectly tokenized as '**' and '='. This only
3279 caused a problem with the -extrude opton.
3281 -Corrected a divide by zero when -extrude option is used
3283 -The flag -w will now contain all errors reported by 'perl -c' on the
3284 input file, but otherwise they are not reported. The reason is that
3285 perl will report lots of problems and syntax errors which are not of
3286 interest when only a small snippet is being formatted (such as missing
3287 modules and unknown bare words). Perltidy will always report all
3288 significant syntax errors that it finds, such as unbalanced braces,
3289 unless the -q (quiet) flag is set.
3291 -Merged modifications created by Hugh Myers into perltidy.
3292 These include a 'streamhandle' routine which allows perltidy
3293 as a module to operate on input and output arrays and strings
3294 in addition to files. Documentation and new packaging as a
3295 module should be ready early next year; This is an elegant,
3296 powerful update; many thanks to Hugh for contributing it.
3301 <pre><code>-added a tentative patch which tries to keep any existing breakpoints
3302 at lines with leading keywords map,sort,eval,grep. The idea is to
3303 improve formatting of sequences of list operations, as in a schwartzian
3307 my @sorted = map { $_->[0] }
3308 sort { $a->[1] <=> $b->[1] }
3309 map { [ $_, rand ] } @list;
3313 map { $_->[0] } sort { $a->[1] <=> $b->[1] } map { [ $_, rand ] } @list;
3316 my @sorted = map { $_->[0] }
3317 sort { $a->[1] <=> $b->[1] }
3318 map { [ $_, rand ] } @list;
3320 The new alignment is not as nice as the input, but this is an improvement.
3321 Thanks to Yves Orton for this suggestion.
3323 -modified indentation logic so that a line with leading opening paren,
3324 brace, or square bracket will never have less indentation than the
3325 line with the corresponding opening token. Here's a simple example:
3329 -text => "New Document",
3330 -command => \&new_document
3332 -side => 'bottom',
3336 Note how the closing ');' is lined up with the first line, even
3337 though it closes a paren in the 'pack' line. That seems wrong.
3341 -text => "New Document",
3342 -command => \&new_document
3344 -side => 'bottom',
3348 This seems nicer: you can up-arrow with an editor and arrive at the
3349 opening 'pack' line.
3351 -corrected minor glitch in which cuddled else (-ce) did not get applied
3352 to an 'unless' block, which should look like this:
3360 Thanks to Jeremy Mates for reporting this.
3362 -The man page has been reorganized to parameters easier to find.
3364 -Added check for multiple definitions of same subroutine. It is easy
3365 to introduce this problem when cutting and pasting. Perl does not
3366 complain about it, but it can lead to disaster.
3368 -The command -pro=filename or -profile=filename may be used to specify a
3369 configuration file which will override the default name of .perltidyrc.
3370 There must not be a space on either side of the '=' sign. I needed
3371 this to be able to easily test perltidy with a variety of different
3372 configuration files.
3374 -Side comment alignment has been improved somewhat across frequent level
3375 changes, as in short if/else blocks. Thanks to Wolfgang Weisselberg
3376 for pointing out this problem. For example:
3379 if ( ref $self ) { # Called as a method
3382 else { # Regular procedure call
3388 if ( ref $self ) { # Called as a method
3391 else { # Regular procedure call
3396 -New command -ssc (--static-side-comment) and related command allows
3397 side comments to be spaced close to preceding character. This is
3398 useful for displaying commented code as side comments.
3400 -New command -csc (--closing-side-comment) and several related
3401 commands allow comments to be added to (and deleted from) any or all
3402 closing block braces. This can be useful if you have to maintain large
3403 programs, especially those that you didn't write. See updated man page.
3404 Thanks to Peter Masiar for this suggestion. For a simple example:
3409 if ( !defined( $_[0] ) ) {
3410 print("Hello, World\n");
3413 print( $_[0], "\n" );
3417 This added '## end sub foo' to the closing brace.
3418 To remove it, perltidy -ncsc.
3420 -New commands -ola, for outdenting labels, and -okw, for outdenting
3421 selected control keywords, were implemented. See the perltidy man
3422 page for details. Thanks to Peter Masiar for this suggestion.
3424 -Hanging side comment change: a comment will not be considered to be a
3425 hanging side comment if there is no leading whitespace on the line.
3426 This should improve the reliability of identifying hanging side comments.
3427 Thanks to Peter Masiar for this suggestion.
3429 -Two new commands for outdenting, -olq (outdent-long-quotes) and -olc
3430 (outdent-long-comments), have been added. The original -oll
3431 (outdent-long-lines) remains, and now is an abbreviation for -olq and -olc.
3432 The new default is just -olq. This was necessary to avoid inconsistency with
3433 the new static block comment option.
3435 -Static block comments: to provide a way to display commented code
3436 better, the convention is used that comments with a leading '##' should
3437 not be formatted as usual. Please see '-sbc' (or '--static-block-comment')
3438 for documentation. It can be deactivated with with -nsbc, but
3439 should not normally be necessary. Thanks to Peter Masiar for this
3442 -Two changes were made to help show structure of complex lists:
3443 (1) breakpoints are forced after every ',' in a list where any of
3444 the list items spans multiple lines, and
3445 (2) List items which span multiple lines now get continuation indentation.
3447 The following example illustrates both of these points. Many thanks to
3448 Wolfgang Weisselberg for this snippet and a discussion of it; this is a
3449 significant formatting improvement. Note how it is easier to see the call
3450 parameters in the NEW version:
3453 assert( __LINE__, ( not defined $check )
3456 or $check eq "old", "Error in parameters",
3457 defined $old_new ? ( ref $old_new ? ref $old_new : $old_new ) : "undef",
3458 defined $db_new ? ( ref $db_new ? ref $db_new : $db_new ) : "undef",
3459 defined $old_db ? ( ref $old_db ? ref $old_db : $old_db ) : "undef" );
3464 ( not defined $check )
3468 "Error in parameters",
3469 defined $old_new ? ( ref $old_new ? ref $old_new : $old_new ) : "undef",
3470 defined $db_new ? ( ref $db_new ? ref $db_new : $db_new ) : "undef",
3471 defined $old_db ? ( ref $old_db ? ref $old_db : $old_db ) : "undef"
3474 Another example shows how this helps displaying lists:
3477 %{ $self->{COMPONENTS} } = (
3479 { type => 'name', adj => 'yes', font => 'Helvetica', 'index' => 0 },
3481 { type => 'road', adj => 'yes', font => 'Helvetica', 'index' => 2 },
3484 The structure is clearer with the added indentation:
3487 %{ $self->{COMPONENTS} } = (
3489 { type => 'name', adj => 'yes', font => 'Helvetica', 'index' => 0 },
3491 { type => 'road', adj => 'yes', font => 'Helvetica', 'index' => 2 },
3494 -The structure of nested logical expressions is now displayed better.
3495 Thanks to Wolfgang Weisselberg for helpful discussions. For example,
3496 note how the status of the final 'or' is displayed in the following:
3500 and null( $op->sibling )
3501 and $op->ppaddr eq "pp_null"
3502 and class($op) eq "UNOP"
3503 and ( ( $op->first->ppaddr =~ /^pp_(and|or)$/
3504 and $op->first->first->sibling->ppaddr eq "pp_lineseq" )
3505 or ( $op->first->ppaddr eq "pp_lineseq"
3506 and not null $op->first->first->sibling
3507 and $op->first->first->sibling->ppaddr eq "pp_unstack" ) ) );
3512 and null( $op->sibling )
3513 and $op->ppaddr eq "pp_null"
3514 and class($op) eq "UNOP"
3517 $op->first->ppaddr =~ /^pp_(and|or)$/
3518 and $op->first->first->sibling->ppaddr eq "pp_lineseq"
3520 or ( $op->first->ppaddr eq "pp_lineseq"
3521 and not null $op->first->first->sibling
3522 and $op->first->first->sibling->ppaddr eq "pp_unstack" )
3526 -A break will always be put before a list item containing a comma-arrow.
3527 This will improve formatting of mixed lists of this form:
3531 'text', 225, 20, -text => 'A Simple Plot',
3539 -text => 'A Simple Plot',
3544 -For convenience, the command -dac (--delete-all-comments) now also
3545 deletes pod. Likewise, -tac (--tee-all-comments) now also sends pod
3546 to a '.TEE' file. Complete control over the treatment of pod and
3547 comments is still possible, as described in the updated help message
3550 -The logic which breaks open 'containers' has been rewritten to be completely
3551 symmetric in the following sense: if a line break is placed after an opening
3552 {, [, or (, then a break will be placed before the corresponding closing
3553 token. Thus, a container either remains closed or is completely cracked
3556 -Improved indentation of parenthesized lists. For example,
3561 atan2( $GPSTempCompLong - $GPSLongitude,
3562 $GPSLatitude - $GPSTempCompLat ) * 180 / 3.14159265 );
3565 $GPSCompCourse = int(
3567 $GPSTempCompLong - $GPSLongitude,
3568 $GPSLatitude - $GPSTempCompLat
3569 ) * 180 / 3.14159265
3572 Further improvements will be made in future releases.
3574 -Some improvements were made in formatting small lists.
3576 -Correspondence between Input and Output line numbers reported in a
3577 .LOG file should now be exact. They were sometimes off due to the size
3578 of intermediate buffers.
3580 -Corrected minor tokenization error in which a ';' in a foreach loop
3581 control was tokenized as a statement termination, which forced a
3594 foreach ( $i = 0 ; $i <= 10 ; $i += 2 ) {
3598 -Corrected a problem with reading config files, in which quote marks were not
3599 stripped. As a result, something like -wba="&& . || " would have the leading
3600 quote attached to the && and not work correctly. A workaround for older
3601 versions is to place a space around all tokens within the quotes, like this:
3602 -wba=" && . || "
3604 -Removed any existing space between a label and its ':'
3607 This was necessary because the label and its colon are a single token.
3609 -Corrected tokenization error for the following (highly non-recommended)
3611 $user = @vars[1] / 100;
3613 -Resolved cause of a difference between perltidy under perl v5.6.1 and
3614 5.005_03; the problem was different behavior of \G regex position
3620 <pre><code>-Corrected a bug in which a break was not being made after a full-line
3621 comment within a short eval/sort/map/grep block. A flag was not being
3622 zeroed. The syntax error check catches this. Here is a snippet which
3623 illustrates the bug:
3626 #open Socket to Dispatcher
3627 $sock = &OpenSocket;
3630 The formatter mistakenly thought that it had found the following
3633 eval {#open Socket to Dispatcher$sock = &OpenSocket; };
3635 The patch fixes this. Many thanks to Henry Story for reporting this bug.
3637 -Changes were made to help diagnose and resolve problems in a
3639 (1) processing of command parameters has been into two separate
3640 batches so that any errors in a .perltidyrc file can be localized.
3641 (2) commands --help, --version, and as many of the --dump-xxx
3642 commands are handled immediately, without any command line processing
3644 (3) Perltidy will ignore any commands in the .perltidyrc file which
3645 cause immediate exit. These are: -h -v -ddf -dln -dop -dsn -dtt
3646 -dwls -dwrs -ss. Thanks to Wolfgang Weisselberg for helpful
3647 suggestions regarding these updates.
3649 -Syntax check has been reinstated as default for MSWin32 systems. This
3650 way Windows 2000 users will get syntax check by default, which seems
3651 like a better idea, since the number of Win 95/98 systems will be
3652 decreasing over time. Documentation revised to warn Windows 95/98
3653 users about the problem with empty '&1'. Too bad these systems
3654 all report themselves as MSWin32.
3659 <pre><code>-Fixed tokenization error in which a method call of the form
3663 got a space before the '::' like this:
3665 Module ::->new();
3667 Thanks to David Holden for reporting this.
3669 -Added -html control over pod text, using a new abbreviation 'pd'. See
3670 updated perl2web man page. The default is to use the color of a comment,
3671 but italicized. Old .css style sheets will need a new line for
3672 .pd to use this. The old color was the color of a string, and there
3675 -.css lines are now printed in sorted order.
3677 -Fixed interpolation problem where html files had '$input_file' as title
3678 instead of actual input file name. Thanks to Simon Perreault for finding
3679 this and sending a patch, and also to Tobias Weber.
3681 -Breaks will now have the ':' placed at the start of a line,
3682 one per line by default because this shows logical structure
3683 more clearly. This coding has been completely redone. Some
3684 examples of new ?/: formatting:
3687 wantarray ? map( $dir::cwd->lookup($_)->path, @_ ) :
3688 $dir::cwd->lookup( $_[0] )->path;
3692 ? map( $dir::cwd->lookup($_)->path, @_ )
3693 : $dir::cwd->lookup( $_[0] )->path;
3696 $a = ( $b > 0 ) ? {
3699 } : { a => 6, b => 8 };
3707 : { a => 6, b => 8 };
3710 $self->note($self->{skip} ? "Hunk #$self->{hunk} ignored at 1.\n" :
3711 "Hunk #$self->{hunk} failed--$@");
3714 $self->note($self->{skip}
3715 ? "Hunk #$self->{hunk} ignored at 1.\n"
3716 : "Hunk #$self->{hunk} failed--$@");
3720 $opts{"t"} ? 'title' :
3721 $opts{"s"} ? 'subject' : $opts{"a"} ? 'author' : 'title';
3725 $opts{"t"} ? 'title'
3726 : $opts{"s"} ? 'subject'
3727 : $opts{"a"} ? 'author'
3730 You can use -wba=':' to recover the previous default which placed ':'
3731 at the end of a line. Thanks to Michael Cartmell for helpful
3732 discussions and examples.
3734 -Tokenizer updated to do syntax checking for matched ?/: pairs. Also,
3735 the tokenizer now outputs a unique serial number for every balanced
3736 pair of brace types and ?/: pairs. This greatly simplifies the
3739 -Long lines with repeated 'and', 'or', '&&', '||' will now have
3740 one such item per line. For example:
3743 if ( $opt_d || $opt_m || $opt_p || $opt_t || $opt_x
3744 || ( -e $archive && $opt_r ) )
3746 ( $pAr, $pNames ) = readAr($archive);
3755 || ( -e $archive && $opt_r ) )
3757 ( $pAr, $pNames ) = readAr($archive);
3761 if ( $vp->{X0} + 4 <= $x && $vp->{X0} + $vp->{W} - 4 >= $x
3762 && $vp->{Y0} + 4 <= $y && $vp->{Y0} + $vp->{H} - 4 >= $y )
3765 if ( $vp->{X0} + 4 <= $x
3766 && $vp->{X0} + $vp->{W} - 4 >= $x
3767 && $vp->{Y0} + 4 <= $y
3768 && $vp->{Y0} + $vp->{H} - 4 >= $y )
3770 -Long lines with multiple concatenated tokens will have concatenated
3771 terms (see below) placed one per line, except for short items. For
3776 "Device type:" . $ib->family . " ID:" . $ib->serial . " CRC:"
3777 . $ib->crc . ": " . $ib->model() . "\n";
3780 $report .= "Device type:"
3781 . $ib->family . " ID:"
3782 . $ib->serial . " CRC:"
3784 . $ib->crc . ": " . "\n";
3786 NOTE: at present 'short' means 8 characters or less. There is a
3787 tentative flag to change this (-scl), but it is undocumented and
3788 is likely to be changed or removed later, so only use it for testing.
3789 In the above example, the tokens " ID:", " CRC:", and "\n" are below
3792 -If a line which is short enough to fit on a single line was
3793 nevertheless broken in the input file at a 'good' location (see below),
3794 perltidy will try to retain a break. For example, the following line
3795 will be formatted as:
3797 open SUM, "<$file"
3798 or die "Cannot open $file ($!)";
3800 if it was broken in the input file, and like this if not:
3802 open SUM, "<$file" or die "Cannot open $file ($!)";
3804 GOOD: 'good' location means before 'and','or','if','unless','&&','||'
3806 The reason perltidy does not just always break at these points is that if
3807 there are multiple, similar statements, this would preclude alignment. So
3808 rather than check for this, perltidy just tries to follow the input style,
3809 in the hopes that the author made a good choice. Here is an example where
3810 we might not want to break before each 'if':
3812 ($Locale, @Locale) = ($English, @English) if (@English > @Locale);
3813 ($Locale, @Locale) = ($German, @German) if (@German > @Locale);
3814 ($Locale, @Locale) = ($French, @French) if (@French > @Locale);
3815 ($Locale, @Locale) = ($Spanish, @Spanish) if (@Spanish > @Locale);
3817 -Added wildcard file expansion for systems with shells which lack this.
3818 Now 'perltidy *.pl' should work under MSDOS/Windows. Thanks to Hugh Myers
3819 for suggesting this. This uses builtin glob() for now; I may change that.
3821 -Added new flag -sbl which, if specified, overrides the value of -bl
3822 for opening sub braces. This allows formatting of this type:
3828 if (!defined($_[0])) {
3829 print("Hello, World\n");
3835 Requested by Don Alexander.
3837 -Fixed minor parsing error which prevented a space after a $$ variable
3838 (pid) in some cases. Thanks to Michael Cartmell for noting this.
3843 -Improved line break choices 'and' and 'or' to display logic better.
3847 exists $self->{'build_dir'} and push @e,
3848 "Unwrapped into directory $self->{'build_dir'}";
3851 exists $self->{'build_dir'}
3852 and push @e, "Unwrapped into directory $self->{'build_dir'}";
3854 -Fixed error of multiple use of abbreviatioin '-dsc'. -dsc remains
3855 abbreviation for delete-side-comments; -dsm is new abbreviation for
3858 -Corrected and updated 'usage' help routine. Thanks to Slaven Rezic for
3861 -The default for Windows is, for now, not to do a 'perl -c' syntax
3862 check (but -syn will activate it). This is because of problems with
3863 command.com. James Freeman sent me a patch which tries to get around
3864 the problems, and it works in many cases, but testing revealed several
3865 issues that still need to be resolved. So for now, the default is no
3866 syntax check for Windows.
3868 -I added a -T flag when doing perl -c syntax check.
3869 This is because I test it on a large number of scripts from sources
3870 unknown, and who knows what might be hidden in initialization blocks?
3871 Also, deactivated the syntax check if perltidy is run as root. As a
3872 benign example, running the previous version of perltidy on the
3873 following file would cause it to disappear:
3876 print "Bye, bye baby!\n";
3880 The new version will not let that happen.
3882 -I am contemplating (but have not yet implemented) making '-lp' the
3883 default indentation, because it is stable now and may be closer to how
3884 perl is commonly formatted. This could be in the next release. The
3885 reason that '-lp' was not the original default is that the coding for
3886 it was complex and not ready for the initial release of perltidy. If
3887 anyone has any strong feelings about this, I'd like to hear. The
3888 current default could always be recovered with the '-nlp' flag.
3893 <pre><code>-html updates:
3894 - sub definition names are now specially colored, red by default.
3895 The letter 'm' is used to identify them.
3896 - keyword 'sub' now has color of other keywords.
3897 - restored html keyword color to __END__ and __DATA__, which was
3898 accidentally removed in the previous version.
3900 -A new -se (--standard-error-output) flag has been implemented and
3901 documented which causes all errors to be written to standard output
3902 instead of a .ERR file.
3904 -A new -w (--warning-output) flag has been implemented and documented
3905 which causes perltidy to output certain non-critical messages to the
3906 error output file, .ERR. These include complaints about pod usage,
3907 for example. The default is to not include these.
3909 NOTE: This replaces an undocumented -w=0 or --warning-level flag
3910 which was tentatively introduced in the previous version to avoid some
3911 unwanted messages. The new default is the same as the old -w=0, so
3912 that is no longer needed.
3914 -Improved syntax checking and corrected tokenization of functions such
3915 as rand, srand, sqrt, ... These can accept either an operator or a term
3916 to their right. This has been corrected.
3918 -Corrected tokenization of semicolon: testing of the previous update showed
3919 that the semicolon in the following statement was being mis-tokenized. That
3920 did no harm, other than adding an extra blank space, but has been corrected.
3922 for (sort {strcoll($a,$b);} keys %investments) {
3926 -New syntax check: after wasting 5 minutes trying to resolve a syntax
3927 error in which I had an extra terminal ';' in a complex for (;;) statement,
3928 I spent a few more minutes adding a check for this in perltidy so it won't
3931 -The behavior of --break-before-subs (-bbs) and --break-before-blocks
3932 (-bbb) has been modified. Also, a new control parameter,
3933 --long-block-line-count=n (-lbl=n) has been introduced to give more
3934 control on -bbb. This was previously a hardwired value. The reason
3935 for the change is to reduce the number of unwanted blank lines that
3936 perltidy introduces, and make it less erratic. It's annoying to remove
3937 an unwanted blank line and have perltidy put it back. The goal is to
3938 be able to sprinkle a few blank lines in that dense script you
3939 inherited from Bubba. I did a lot of experimenting with different
3940 schemes for introducing blank lines before and after code blocks, and
3941 decided that there is no really good way to do it. But I think the new
3942 scheme is an improvement. You can always deactivate this with -nbbb.
3943 I've been meaning to work on this; thanks to Erik Thaysen for bringing
3946 -The .LOG file is seldom needed, and I get tired of deleting them, so
3947 they will now only be automatically saved if perltidy thinks that it
3948 made an error, which is almost never. You can still force the logfile
3949 to be saved with -log or -g.
3951 -Improved method for computing number of columns in a table. The old
3952 method always tried for an even number. The new method allows odd
3953 numbers when it is obvious that a list is not a hash initialization
3957 $name, $xsargs, $parobjs, $optypes,
3958 $hasp2child, $pmcode, $hdrcode, $inplacecode,
3959 $globalnew, $callcopy
3964 $name, $xsargs, $parobjs, $optypes, $hasp2child,
3965 $pmcode, $hdrcode, $inplacecode, $globalnew, $callcopy
3969 -I fiddled with the list threshold adjustment, and some small lists
3970 look better now. Here is the change for one of the lists in test file
3974 ("in", "in", "pt", "pt", "pc", "pi", "mm", "mm", "cm", "cm", "\\hsize", "%",
3975 "\\vsize", "%", "\\textwidth", "%", "\\textheight", "%");
3979 "in", "in", "pt", "pt", "pc", "pi",
3980 "mm", "mm", "cm", "cm", "\\hsize", "%",
3981 "\\vsize", "%", "\\textwidth", "%", "\\textheight", "%"
3984 -Improved -lp formatting at '=' sign. A break was always being added after
3985 the '=' sign in a statement such as this, (to be sure there was enough room
3986 for the parameters):
3991 $biblionumber, $constraint,
3995 The updated version doesn't do this unless the space is really needed:
3997 new: my $fee = CalcReserveFee(
3999 $biblionumber, $constraint,
4003 -I updated the tokenizer to allow $#+ and $#-, which seem to be new to
4004 Perl 5.6. Some experimenting with a recent version of Perl indicated
4005 that it allows these non-alphanumeric '$#' array maximum index
4006 variables: $#: $#- $#+ so I updated the parser accordingly. Only $#:
4007 seems to be valid in older versions of Perl.
4009 -Fixed a rare formatting problem with -lp (and -gnu) which caused
4010 excessive indentation.
4012 -Many additional syntax checks have been added.
4014 -Revised method for testing here-doc target strings; the following
4015 was causing trouble with a regex test because of the '*' characters:
4016 print <<"*EOF*";
4019 Perl seems to allow almost anything to be a here doc target, so an
4020 exact string comparison is now used.
4022 -Made update to allow underscores in binary numbers, like '0b1100_0000'.
4024 -Corrected problem with scanning certain module names; a blank space was
4025 being inserted after 'warnings' in the following:
4026 use warnings::register;
4027 The problem was that warnings (and a couple of other key modules) were
4028 being tokenized as keywords. They should have just been identifiers.
4030 -Corrected tokenization of indirect objects after sort, system, and exec,
4031 after testing produced an incorrect error message for the following
4033 print sort $sortsubref @list;
4035 -Corrected minor problem where a line after a format had unwanted
4036 extra continuation indentation.
4038 -Delete-block-comments (and -dac) now retain any leading hash-bang line
4040 -Update for -lp (and -gnu) to not align the leading '=' of a list
4041 with a previous '=', since this interferes with alignment of parameters.
4043 old: my $hireDay = new Date;
4045 firstName => undef,
4046 lastName => undef,
4047 hireDay => $hireDay
4050 new: my $hireDay = new Date;
4052 firstName => undef,
4053 lastName => undef,
4054 hireDay => $hireDay
4057 -Modifications made to display tables more compactly when possible,
4058 without adding lines. For example,
4060 '1', "I", '2', "II", '3', "III", '4', "IV",
4061 '5', "V", '6', "VI", '7', "VII", '8', "VIII",
4064 '1', "I", '2', "II", '3', "III",
4065 '4', "IV", '5', "V", '6', "VI",
4066 '7', "VII", '8', "VIII", '9', "IX"
4068 -Corrected minor bug in which -pt=2 did not keep the right paren tight
4069 around a '++' or '--' token, like this:
4071 for ($i = 0 ; $i < length $key ; $i++ )
4073 The formatting for this should be, and now is:
4075 for ($i = 0 ; $i < length $key ; $i++)
4077 Thanks to Erik Thaysen for noting this.
4079 -Discovered a new bug involving here-docs during testing! See BUGS.html.
4081 -Finally fixed parsing of subroutine attributes (A Perl 5.6 feature).
4082 However, the attributes and prototypes must still be on the same line
4088 <pre><code>-Corrected minor, uncommon bug found during routine testing, in which a
4089 blank got inserted between a function name and its opening paren after
4090 a file test operator, but only in the case that the function had not
4091 been previously seen. Perl uses the existence (or lack thereof) of
4092 the blank to guess if it is a function call. That is,
4093 if (-l pid_filename()) {
4095 if (-l pid_filename ()) {
4096 which is a syntax error if pid_filename has not been seen by perl.
4098 -If the AutoLoader module is used, perltidy will continue formatting
4099 code after seeing an __END__ line. Use -nlal to deactivate this feature.
4100 Likewise, if the SelfLoader module is used, perltidy will continue
4101 formatting code after seeing a __DATA__ line. Use -nlsl to
4102 deactivate this feature. Thanks to Slaven Rezic for this suggestion.
4104 -pod text after __END__ and __DATA__ is now identified by perltidy
4105 so that -dp works correctly. Thanks to Slaven Rezic for this suggestion.
4107 -The first $VERSION line which might be eval'd by MakeMaker
4108 is now passed through unchanged. Use -npvl to deactivate this feature.
4109 Thanks to Manfred Winter for this suggestion.
4111 -Improved indentation of nested parenthesized expressions. Tests have
4112 given favorable results. Thanks to Wolfgang Weisselberg for helpful
4118 <pre><code>-Fixed a very rare problem in which an unwanted semicolon was inserted
4119 due to misidentification of anonymous hash reference curly as a code
4120 block curly. (No instances of this have been reported; I discovered it
4121 during testing). A workaround for older versions of perltidy is to use
4124 -Added -icb (-indent-closing-brace) parameter to indent a brace which
4125 terminates a code block to the same level as the previous line.
4126 Suggested by Andrew Cutler. For example,
4135 -Rewrote error message triggered by an unknown bareword in a print or
4136 printf filehandle position, and added flag -w=0 to prevent issuing this
4137 error message. Suggested by Byron Jones.
4139 -Added modification to align a one-line 'if' block with similar
4140 following 'elsif' one-line blocks, like this:
4141 if ( $something eq "simple" ) { &handle_simple }
4142 elsif ( $something eq "hard" ) { &handle_hard }
4143 (Suggested by Wolfgang Weisselberg).
4148 <pre><code>-Eliminated all constants with leading underscores because perl 5.005_03
4149 does not support that. For example, _SPACES changed to XX_SPACES.
4150 Thanks to kromJx for this update.
4155 <pre><code>-the directory of test files has been moved to a separate distribution
4156 file because it is getting large but is of little interest to most users.
4157 For the current distribution:
4158 perltidy-20010701.tgz contains the source and docs for perltidy
4159 perltidy-20010701-test.tgz contains the test files
4161 -fixed bug where temporary file perltidy.TMPI was not being deleted
4162 when input was from stdin.
4164 -adjusted line break logic to not break after closing brace of an
4165 eval block (suggested by Boris Zentner).
4167 -added flag -gnu (--gnu-style) to give an approximation to the GNU
4168 style as sometimes applied to perl. The programming style in GNU
4169 'automake' was used as a guide in setting the parameters; these
4170 parameters will probably be adjusted over time.
4172 -an empty code block now has one space for emphasis:
4173 if ( $cmd eq "bg_untested" ) {} # old
4174 if ( $cmd eq "bg_untested" ) { } # new
4175 If this bothers anyone, we could create a parameter.
4177 -the -bt (--brace-tightness) parameter has been split into two
4178 parameters to give more control. -bt now applies only to non-BLOCK
4179 braces, while a new parameter -bbt (block-brace-tightness) applies to
4180 curly braces which contain code BLOCKS. The default value is -bbt=0.
4182 -added flag -icp (--indent-closing-paren) which leaves a statement
4183 termination of the form );, };, or ]; indented with the same
4184 indentation as the previous line. For example,
4186 @month_of_year = ( # default, or -nicp
4187 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct',
4191 @month_of_year = ( # -icp
4192 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct',
4196 -Vertical alignment updated to synchronize with tokens &&, ||,
4197 and, or, if, unless. Allowable space before forcing
4198 resynchronization has been increased. (Suggested by Wolfgang
4201 -html corrected to use -nohtml-bold-xxxxxxx or -nhbx to negate bold,
4202 and likewise -nohtml-italic-xxxxxxx or -nhbi to negate italic. There
4203 was no way to negate these previously. html documentation updated and
4204 corrected. (Suggested by Wolfgang Weisselberg).
4206 -Some modifications have been made which improve the -lp formatting in
4209 -Perltidy now retains or creates a blank line after an =cut to keep
4210 podchecker happy (Suggested by Manfred H. Winter). This appears to be
4211 a glitch in podchecker, but it was annoying.
4216 <pre><code>-Added -bli flag to give continuation indentation to braces, like this
4220 extra_indentation();
4223 -Corrected an error with the tab (-t) option which caused the last line
4224 of a multi-line quote to receive a leading tab. This error was in
4225 version 2001 06 08 but not 2001 04 06. If you formatted a script
4226 with -t with this version, please check it by running once with the
4227 -chk flag and perltidy will scan for this possible error.
4229 -Corrected an invalid pattern (\R should have been just R), changed
4230 $^W =1 to BEGIN {$^W=1} to use warnings in compile phase, and corrected
4231 several unnecessary 'my' declarations. Many thanks to Wolfgang Weisselberg,
4232 2001-06-12, for catching these errors.
4234 -A '-bar' flag has been added to require braces to always be on the
4235 right, even for multi-line if and foreach statements. For example,
4236 the default formatting of a long if statement would be:
4238 if ($bigwasteofspace1 && $bigwasteofspace2
4239 || $bigwasteofspace3 && $bigwasteofspace4)
4244 With -bar, the formatting is:
4246 if ($bigwasteofspace1 && $bigwasteofspace2
4247 || $bigwasteofspace3 && $bigwasteofspace4) {
4250 Suggested by Eli Fidler 2001-06-11.
4252 -Uploaded perltidy to sourceforge cvs 2001-06-10.
4254 -An '-lp' flag (--line-up-parentheses) has been added which causes lists
4255 to be indented with extra indentation in the manner sometimes
4256 associated with emacs or the GNU suggestions. Thanks to Ian Stuart for
4257 this suggestion and for extensive help in testing it.
4259 -Subroutine call parameter lists are now formatted as other lists.
4260 This should improve formatting of tables being passed via subroutine
4261 calls. This will also cause full indentation ('-i=n, default n= 4) of
4262 continued parameter list lines rather than just the number of spaces
4263 given with -ci=n, default n=2.
4265 -Added support for hanging side comments. Perltidy identifies a hanging
4266 side comment as a comment immediately following a line with a side
4267 comment or another hanging side comment. This should work in most
4268 cases. It can be deactivated with --no-hanging-side-comments (-nhsc).
4269 The manual has been updated to discuss this. Suggested by Brad
4270 Eisenberg some time ago, and finally implemented.
4275 <pre><code>-fixed problem with parsing command parameters containing quoted
4276 strings in .perltidyrc files. (Reported by Roger Espel Llima 2001-06-07).
4278 -added two command line flags, --want-break-after and
4279 --want-break-before, which allow changing whether perltidy
4280 breaks lines before or after any operators. Please see the revised
4281 man pages for details.
4283 -added system-wide configuration file capability.
4284 If perltidy does not find a .perltidyrc command line file in
4285 the current directory, nor in the home directory, it now looks
4286 for '/usr/local/etc/perltidyrc' and then for '/etc/perltidyrc'.
4287 (Suggested by Roger Espel Llima 2001-05-31).
4289 -fixed problem in which spaces were trimmed from lines of a multi-line
4290 quote. (Reported by Roger Espel Llima 2001-05-30). This is an
4291 uncommon situation, but serious, because it could conceivably change
4292 the proper function of a script.
4294 -fixed problem in which a semicolon was incorrectly added within
4295 an anonymous hash. (Reported by A.C. Yardley, 2001-5-23).
4296 (You would know if this happened, because perl would give a syntax
4297 error for the resulting script).
4299 -fixed problem in which an incorrect error message was produced
4300 after a version number on a 'use' line, like this ( Reported
4301 by Andres Kroonmaa, 2001-5-14):
4303 use CGI 2.42 qw(fatalsToBrowser);
4305 Other than the extraneous error message, this bug was harmless.
4310 <pre><code>-fixed serious bug in which the last line of some multi-line quotes or
4311 patterns was given continuation indentation spaces. This may make
4312 a pattern incorrect unless it uses the /x modifier. To find
4313 instances of this error in scripts which have been formatted with
4314 earlier versions of perltidy, run with the -chk flag, which has
4315 been added for this purpose (SLH, 2001-04-05).
4317 ** So, please check previously formatted scripts by running with -chk
4320 -continuation indentation has been reprogrammed to be hierarchical,
4321 which improves deeply nested structures.
4323 -fixed problem with undefined value in list formatting (reported by Michael
4326 -Switched to graphical display of nesting in .LOG files. If an
4327 old format string was "(1 [0 {2", the new string is "{{(". This
4328 is easier to read and also shows the order of nesting.
4330 -added outdenting of cuddled paren structures, like ")->pack(".
4332 -added line break and outdenting of ')->' so that instead of
4335 -text => "perltidy",
4336 -relief => 'ridge')->pack;
4338 the current default is:
4341 -text => "perltidy",
4342 -relief => 'ridge'
4345 (requested by Michael Langner 2001-03-31; in the future this could
4346 be controlled by a command-line parameter).
4348 -revised list indentation logic, so that lists following an assignment
4349 operator get one full indentation level, rather than just continuation
4350 indentation. Also corrected some minor glitches in the continuation
4353 -Fixed problem with unwanted continuation indentation after a blank line
4354 (reported by Erik Thaysen 2001-03-28):
4356 -minor update to avoid stranding a single '(' on one line
4359 <h2>2001 03 28:</h2>
4361 <pre><code>-corrected serious error tokenizing filehandles, in which a sub call
4362 after a print or printf, like this:
4363 print usage() and exit;
4365 print usage () and exit;
4366 Unfortunately, this converts 'usage' to a filehandle. To fix this, rerun
4367 perltidy; it will look for this situation and issue a warning.
4369 -fixed another cuddled-else formatting bug (Reported by Craig Bourne)
4371 -added several diagnostic --dump routines
4373 -added token-level whitespace controls (suggested by Hans Ecke)
4376 <h2>2001 03 23:</h2>
4378 <pre><code>-added support for special variables of the form ${^WANT_BITS}
4380 -space added between scalar and left paren in 'for' and 'foreach' loops,
4381 (suggestion by Michael Cartmell):
4383 for $i( 1 .. 20 ) # old
4384 for $i ( 1 .. 20 ) # new
4386 -html now outputs cascading style sheets (thanks to suggestion from
4389 -flags -o and -st now work with -html
4391 -added missing -html documentation for comments (noted by Alex Izvorski)
4393 -support for VMS added (thanks to Michael Cartmell for code patches and
4396 -v-strings implemented (noted by Hans Ecke and Michael Cartmell; extensive
4397 testing by Michael Cartmell)
4399 -fixed problem where operand may be empty at line 3970
4400 (\b should be just b in lines 3970, 3973) (Thanks to Erik Thaysen,
4401 Keith Marshall for bug reports)
4403 -fixed -ce bug (cuddled else), where lines like '} else {' were indented
4404 (Thanks to Shawn Stepper and Rick Measham for reporting this)
4407 <h2>2001 03 04:</h2>
4409 <pre><code>-fixed undefined value in line 153 (only worked with -I set)
4410 (Thanks to Mike Stok, Phantom of the Opcodes, Ian Ehrenwald, and others)
4412 -fixed undefined value in line 1069 (filehandle problem with perl versions <
4413 5.6) (Thanks to Yuri Leikind, Mike Stok, Michael Holve, Jeff Kolber)
4416 <h2>2001 03 03:</h2>
4418 <pre><code>-Initial announcement at freshmeat.net; started Change Log
