3 - RT #124469, #124494, perltidy often making empty files. The previous had
4 an index error causing it to fail, particularly in version 5.18 of Perl.
6 Please avoid version 20180219.
9 - RT #79947, cuddled-else generalization. A new flag -cb provides
10 'cuddled-else' type formatting for an arbitrary type of block chain. The
11 default is try-catch-finally, but this can be modified with the
14 - Fixed RT #124298: add space after ! operator without breaking !! secret
17 - RT #123749: numerous minor improvements to the -wn flag were made.
19 - Fixed a problem with convergence tests in which iterations were stopping
22 - Here doc targets for <<~ type here-docs may now have leading whitespace.
24 - Fixed RT #124354. The '-indent-only' flag was not working correctly in the
25 previous release. A bug in version 20180101 caused extra blank lines
28 - Issue RT #124114. Some improvements were made in vertical alignment
29 involving 'fat commas'.
32 - Added new flag -wn (--weld-nested-containers) which addresses these issues:
33 RT #123749: Problem with promises;
34 RT #119970: opening token stacking strange behavior;
35 RT #81853: Can't stack block braces
37 This option causes closely nested pairs of opening and closing containers
38 to be "welded" together and essentially be formatted as a single unit,
39 with just one level of indentation.
41 Since this is a new flag it is set to be "off" by default but it has given
42 excellent results in testing.
44 EXAMPLE 1, multiple blocks, default formatting:
47 next if $x == $y; # do something here
56 EXAMPLE 2, three levels of wrapped function calls, default formatting:
60 translate( param('verb') ), param('tense'),
68 translate( param('verb') ),
69 param('tense'), param('person')
72 # EXAMPLE 3, chained method calls, default formatting:
73 get('http://mojolicious.org')->then(
77 return get('http://metacpan.org');
87 warn "Something went wrong: $err";
92 get('http://mojolicious.org')->then( sub {
95 return get('http://metacpan.org');
101 warn "Something went wrong: $err";
105 - Fixed RT #114359: Missparsing of "print $x ** 0.5;
107 - Deactivated the --check-syntax flag for better security. It will be
110 - Corrected minimum perl version from 5.004 to 5.008 based on perlver
111 report. The change is required for coding involving wide characters.
113 - For certain severe errors, the source file will be copied directly to the
114 output without formatting. These include ending in a quote, ending in a
115 here doc, and encountering an unidentified character.
118 - RT #123749, partial fix. "Continuation indentation" is removed from lines
119 with leading closing parens which are part of a call chain.
120 For example, the call to pack() is is now outdented to the starting
121 indentation in the following experession:
125 -text => "New Document",
126 -command => \&new_document
134 -text => "New Document",
135 -command => \&new_document
141 This modification improves readability of complex expressions, especially
142 when the user uses the same value for continuation indentation (-ci=n) and
143 normal indentation (-i=n). Perltidy was already programmed to
144 do this but a minor bug was preventing it.
146 - RT #123774, added flag to control space between a backslash and a single or
147 double quote, requested by Robert Rothenberg. The issue is that lines like
152 confuse syntax highlighters unless a space is left between the backslash and
155 The new flag to control this is -sbq=n (--space-backslash-quote=n),
156 where n=0 means no space, n=1 means follow existing code, n=2 means always
157 space. The default is n=1, meaning that a space will be retained if there
158 is one in the source code.
160 - Fixed RT #123492, support added for indented here doc operator <<~ added
161 in v5.26. Thanks to Chris Weyl for the report.
163 - Fixed docs; --closing-side-comment-list-string should have been just
164 --closing-side-comment-list. Thanks to F.Li.
166 - Added patch RT #122030] Perl::Tidy sometimes does not call binmode.
167 Thanks to Irilis Aelae.
169 - Fixed RT #121959, PERLTIDY doesn't honor the 'three dot' notation for
170 locating a config file using environment variables. Thanks to John
173 - Minor improvements to formatting, in which some additional vertical
174 aligmnemt is done. Thanks to Keith Neargarder.
176 - RT #119588. Vertical alignment is no longer done for // operator.
179 - Fixed debian #862667: failure to check for perltidy.ERR deletion can lead
180 to overwriting abritrary files by symlink attack. Perltidy was continuing
181 to write files after an unlink failure. Thanks to Don Armstrong
184 - Fixed RT #116344, perltidy fails on certain anonymous hash references:
185 in the following code snippet the '?' was misparsed as a pattern
186 delimiter rather than a ternary operator.
187 return ref {} ? 1 : 0;
189 - Fixed RT #113792: misparsing of a fat comma (=>) right after
190 the __END__ or __DATA__ tokens. These keywords were getting
191 incorrectly quoted by the following => operator.
193 - Fixed RT #118558. Custom Getopt::Long configuration breaks parsing
194 of perltidyrc. Perltidy was resetting the users configuration too soon.
196 - Fixed RT #119140, failure to parse double diamond operator. Code to
197 handle this new operator has been added.
199 - Fixed RT #120968. Fixed problem where -enc=utf8 didn't work
200 with --backup-and-modify-in-place. Thanks to Heinz Knutzen for this patch.
202 - Fixed minor formatting issue where one-line blocks for subs with signatures
203 were unnecesarily broken
205 - RT #32905, patch to fix utf-8 error when output was STDOUT.
207 - RT #79947, improved spacing of try/catch/finally blocks. Thanks to qsimpleq
210 - Fixed #114909, Anonymous subs with signatures and prototypes misparsed as
211 broken ternaries, in which a statement such as this was not being parsed
213 return sub ( $fh, $out ) : prototype(*$) { ... }
215 - Implemented RT #113689, option to introduces spaces after an opening block
216 brace and before a closing block brace. Four new optional controls are
217 added. The first two define the minimum number of blank lines to be
220 -blao=i or --blank-lines-after-opening-block=i
221 -blbc=i or --blank-lines-before-closing-block=i
223 where i is an integer, the number of lines (the default is 0).
225 The second two define the types of blocks to which the first two apply
227 -blaol=s or --blank-lines-after-opening-block-list=s
228 -blbcl=s or --blank-lines-before-closing-block-list=s
230 where s is a string of possible block keywords (default is just 'sub',
231 meaning a named subroutine).
233 For more information please see the documentation.
235 - The method for specifying block types for certain input parameters has
236 been generalized to distinguish between normal named subroutines and
237 anonymous subs. The keyword for normal subroutines remains 'sub', and
238 the new keyword for anonymous subs is 'asub'.
240 - Minor documentation changes. The BUGS sections now have a link
241 to CPAN where most open bugs and issues can be reviewed and bug reports
242 can be submitted. The information in the AUTHOR and CREDITS sections of
243 the man pages have been removed from the man pages to streamline the
244 documentation. This information is still in the source code.
247 - RT #112534. Corrected a minor problem in which an unwanted newline
248 was placed before the closing brace of an anonymous sub with
249 a signature, if it was in a list. Thanks to Dmytro Zagashev.
251 - Corrected a minor problem in which occasional extra indentation was
252 given to the closing brace of an anonymous sub in a list when the -lp
256 - RT #104427. Added support for signatures.
258 - RT #111512. Changed global warning flag $^W = 1 to use warnings;
259 Thanks to Dmytro Zagashev.
261 - RT #110297, added support for new regexp modifier /n
262 Thanks to Dmytro Zagashev.
264 - RT #111519. The -io (--indent-only) and -dac (--delete-all-comments)
265 can now both be used in one pass. Thanks to Dmitry Veltishev.
267 - Patch to avoid error message with 'catch' used by TryCatch, as in
271 Thanks to Nick Tonkin.
273 - RT #32905, UTF-8 coding is now more robust. Thanks to qsimpleq
274 and Dmytro for patches.
276 - RT #106885. Added string bitwise operators ^. &. |. ~. ^.= &.= |.=
278 - Fixed RT #107832 and #106492, lack of vertical alignment of two lines
279 when -boc flag (break at old commas) is set. This bug was
280 inadvertantly introduced in previous bug fix RT #98902.
282 - Some common extensions to Perl syntax are handled better.
283 In particular, the following snippet is now foratted cleanly:
285 method deposit( Num $amount) {
286 $self->balance( $self->balance + $amount );
289 A new flag -xs (--extended-syntax) was added to enable this, and the default
292 In previous versions, and now only when -nxs is set, this snippet of code
293 generates the following error message:
295 "syntax error at ') {', didn't see one of: case elsif for foreach given if switch unless until when while"
298 - Fixed RT# 105484, Invalid warning about 'else' in 'switch' statement. The
299 warning happened if a 'case' statement did not use parens.
301 - Fixed RT# 101547, misparse of // caused error message. Also..
303 - Fixed RT# 102371, misparse of // caused unwated space in //=
305 - Fixed RT# 100871, "silent failure of HTML Output on Windows".
306 Changed calls to tempfile() from:
307 my ( $fh_tmp, $tmpfile ) = tempfile();
308 to have the full path name:
309 my ( $fh_tmp, $tmpfile ) = File::Temp::tempfile()
310 because of problems in the Windows version reported by Dean Pearce.
312 - Fixed RT# 99514, calling the perltidy module multiple times with
313 a .perltidyrc file containing the parameter --output-line-ending
314 caused a crash. This was a glitch in the memoization logic.
316 - Fixed RT#99961, multiple lines inside a cast block caused unwanted
317 continuation indentation.
319 - RT# 32905, broken handling of UTF-8 strings.
320 A new flag -utf8 causes perltidy assume UTF-8 encoding for input and
321 output of an io stream. Thanks to Sebastian Podjasek for a patch.
322 This feature may not work correctly in older versions of Perl.
323 It worked in a linux version 5.10.1 but not in a Windows version 5.8.3 (but
324 otherwise perltidy ran correctly).
326 - Warning files now report perltidy VERSION. Suggested by John Karr.
328 - Fixed long flag --nostack-closing-tokens (-nsct has always worked though).
329 This was due to a typo. This also fixed --nostack-opening-tokens to
330 behave correctly. Thanks to Rob Dixon.
333 - Fixed RT #94902: abbreviation parsing in .perltidyrc files was not
334 working for multi-line abbreviations. Thanks to Eric Fung for
337 - Fixed RT #95708, misparsing of a hash when the first key was a perl
338 keyword, causing a semicolon to be incorrectly added.
340 - Fixed RT #94338 for-loop in a parenthesized block-map. A code block within
341 parentheses of a map, sort, or grep function was being mistokenized. In
342 rare cases this could produce in an incorrect error message. The fix will
343 produce some minor formatting changes. Thanks to Daniel Trizen
344 discovering and documenting this.
346 - Fixed RT #94354, excess indentation for stacked tokens. Thanks to
347 Colin Williams for supplying a patch.
349 - Added support for experimental postfix dereferencing notation introduced in
350 perl 5.20. RT #96021.
352 - Updated documentation to clarify the behavior of the -io flag
353 in response to RT #95709. You can add -noll or -l=0 to prevent
354 long comments from being outdented when -io is used.
356 - Added a check to prevent a problem reported in RT #81866, where large
357 scripts which had been compressed to a single line could not be formatted
358 because of a check for VERSION for MakeMaker. The workaround was to
359 use -nvpl, but this shouldn't be necessary now.
361 - Fixed RT #96101; Closing brace of anonymous sub in a list was being
362 indented. For example, the closing brace of the anonymous sub below
363 will now be lined up with the word 'callback'. This problem
364 occured if there was no comma after the closing brace of the anonymous sub.
365 This update may cause minor changes to formatting of code with lists
366 of anonymous subs, especially TK code.
373 path => '/_Operate/Transcode and split',
375 return 1 if not $self->project_opened;
376 $self->comp('project')->transcode( split => 1 );
386 path => '/_Operate/Transcode and split',
388 return 1 if not $self->project_opened;
389 $self->comp('project')->transcode( split => 1 );
395 - Fixed RT #94190 and debian Bug #742004: perltidy.LOG file left behind.
396 Thanks to George Hartzell for debugging this. The problem was
397 caused by the memoization speedup patch in version 20121207. An
398 unwanted flag was being set which caused a LOG to be written if
399 perltidy was called multiple times.
401 - New default behavior for LOG files: If the source is from an array or
402 string (through a call to the perltidy module) then a LOG output is only
403 possible if a logfile stream is specified. This is to prevent
404 unexpected perltidy.LOG files.
406 - Fixed debian Bug #740670, insecure temporary file usage. File::Temp is now
407 used to get a temporary file. Thanks to Don Anderson for a patch.
409 - Any -b (--backup-and-modify-in-place) flag is silently ignored when a
410 source stream, destination stream, or standard output is used.
411 This is because the -b flag may have been in a .perltidyrc file and
412 warnings break Test::NoWarnings. Thanks to Marijn Brand.
415 - Fixed RT #88020. --converge was not working with wide characters.
417 - Fixed RT #78156. package NAMESPACE VERSION syntax not accepted.
419 - First attempt to fix RT #88588. INDEX END tag change in pod2html breaks
420 perltidy -html. I put in a patch which should work but I don't yet have
424 - Fixed RT #87107, spelling
427 - Fixed RT #87502, incorrect of parsing of smartmatch before hash brace
429 - Added feature request RT #87330, trim whitespace after POD.
430 The flag -trp (--trim-pod) will trim trailing whitespace from lines of POD
433 - Fixed RT #86929, #86930, missing lhs of assignment.
435 - Fixed RT #84922, moved pod from Tidy.pm into Tidy.pod
438 - The flag -cab=n or --comma-arrow-breakpoints=n has been generalized
439 to give better control over breaking open short containers. The
440 possible values are now:
442 n=0 break at all commas after =>
443 n=1 stable: break at all commas after => if container is open,
444 EXCEPT FOR one-line containers
445 n=2 break at all commas after =>, BUT try to form the maximum
446 maximum one-line container lengths
447 n=3 do not treat commas after => specially at all
448 n=4 break everything: like n=0 but also break a short container with
449 a => not followed by a comma
450 n=5 stable: like n=1 but ALSO break at open one-line containers (default)
452 New values n=4 and n=5 have been added to allow short blocks to be
453 broken open. The new default is n=5, stable. It should more closely
454 follow the breaks in the input file, and previously formatted code
455 should remain unchanged. If this causes problems use -cab=1 to recover
456 the former behavior. Thanks to Tony Maszeroski for the suggestion.
458 To illustrate the need for the new options, if perltidy is given
459 the following code, then the old default (-cab=1) was to close up
460 the 'index' container even if it was open in the source. The new
461 default (-cab=5) will keep it open if it was open in the source.
476 - New debug flag --memoize (-mem). This version contains a
477 patch supplied by Jonathan Swartz which can significantly speed up
478 repeated calls to Perl::Tidy::perltidy in a single process by caching
479 the result of parsing the formatting parameters. A factor of up to 10
480 speedup was achieved for masontidy (https://metacpan.org/module/masontidy).
481 The memoization patch is on by default but can be deactivated for
482 testing with -nmem (or --no-memoize).
484 - New flag -tso (--tight-secret-operators) causes certain perl operator
485 sequences (secret operators) to be formatted "tightly" (without spaces).
486 The most common of these are 0 + and + 0 which become 0+ and +0. The
487 operators currently modified by this flag are:
488 =( )= 0+ +0 ()x!! ~~<> ,=>
489 Suggested by by Philippe Bruhat. See https://metacpan.org/module/perlsecret
490 This flag is off by default.
492 - New flag -vmll (--variable-maximum-line-length) makes the maximum
493 line length increase with the nesting depth of a line of code.
494 Basically, it causes the length of leading whitespace to be ignored when
495 setting line breaks, so the formatting of a block of code is independent
496 of its nesting depth. Try this option if you have deeply nested
497 code or data structures, perhaps in conjunction with the -wc flag
498 described next. The default is not todo this.
500 - New flag -wc=n (--whitespace-cycle=n) also addresses problems with
501 very deeply nested code and data structures. When this parameter is
502 used and the nesting depth exceeds the value n, the leading whitespace
503 will be reduced and start at 1 again. The result is that deeply
504 nested blocks of code will shift back to the left. This occurs cyclically
505 to any nesting depth. This flag may be used either with or without -vmll.
506 The default is not to use this (-wc=0).
508 - Fixed RT #78764, error parsing smartmatch operator followed by anonymous
509 hash or array and then a ternary operator; two examples:
511 qr/3/ ~~ ['1234'] ? 1 : 0;
512 map { $_ ~~ [ '0', '1' ] ? 'x' : 'o' } @a;
514 - Fixed problem with specifying spaces around arrows using -wls='->'
515 and -wrs='->'. Thanks to Alain Valleton for documenting this problem.
517 - Implemented RT #53183, wishlist, lines of code with the same indentation
518 level which are contained with multiple stacked opening and closing tokens
519 (requested with flags -sot -sct) now have reduced indentation.
530 # OLD: perltidy -sot -sct
537 # NEW: perltidy -sot -sct
544 - New flag -act=n (--all-containers-tightness=n) is an abbreviation for
545 -pt=n -sbt=n -bt=n -bbt=n, where n=0,1, or 2. It simplifies input when all
546 containers have the same tightness. Using the same example:
548 # NEW: perltidy -sot -sct -act=2
555 - New flag -sac (--stack-all-containers) is an abbreviation for -sot -sct
556 This is part of wishlist item RT #53183. Using the same example again:
558 # NEW: perltidy -sac -act=2
565 - new flag -scbb (--stack-closing-block-brace) causes isolated closing
566 block braces to stack as in the following example. (Wishlist item RT#73788)
573 push( @lines, "$w1 $w2 $w3 $w4\n" );
584 push( @lines, "$w1 $w2 $w3 $w4\n" );
587 There is, at present, no flag to place these closing braces at the end
588 of the previous line. It seems difficult to develop good rules for
589 doing this for a wide variety of code and data structures.
591 - Parameters defining block types may use a wildcard '*' to indicate
592 all block types. Previously it was not possible to include bare blocks.
594 - A flag -sobb (--stack-opening-block-brace) has been introduced as an
595 alias for -bbvt=2 -bbvtl='*'. So for example the following test code:
597 {{{{{{{ $testing }}}}}}}
599 cannot be formatted as above but can at least be kept vertically compact
600 using perltidy -sobb -scbb
602 { { { { { { { $testing
605 Or even, perltidy -sobb -scbb -i=1 -bbt=2
610 - Error message improved for conflicts due to -pbp; thanks to Djun Kim.
612 - Fixed RT #80645, error parsing special array name '@$' when used as
615 - Eliminated the -chk debug flag which was included in version 20010406 to
616 do a one-time check for a bug with multi-line quotes. It has not been
619 - Numerous other minor formatting improvements.
622 - Added flag -iscl (--ignore-side-comment-lengths) which causes perltidy
623 to ignore the length of side comments when setting line breaks,
624 RT #71848. The default is to include the length of side comments when
625 breaking lines to stay within the length prescribed by the -l=n
626 maximum line length parameter. For example,
628 Default behavior on a single line with long side comment:
629 $vmsfile =~ s/;[\d\-]*$//
630 ; # Clip off version number; we can use a newer version as well
632 perltidy -iscl leaves the line intact:
634 $vmsfile =~ s/;[\d\-]*$//; # Clip off version number; we can use a newer version as well
636 - Fixed RT #78182, side effects with STDERR. Error handling has been
637 revised and the documentation has been updated. STDERR can now be
638 redirected to a string reference, and perltidy now returns an
639 error flag instead of calling die when input errors are detected.
640 If the error flag is set then no tidied output was produced.
641 See man Perl::Tidy for an example.
643 - Fixed RT #78156, erroneous warning message for package VERSION syntax.
645 - Added abbreviations -conv (--converge) to simplify iteration control.
646 -conv is equivalent to -it=4 and will insure that the tidied code is
647 converged to its final state with the minimum number of iterations.
649 - Minor formatting modifications have been made to insure convergence.
651 - Simplified and hopefully improved the method for guessing the starting
652 indentation level of entabbed code. Added flag -dt=n (--default_tabsize=n)
653 which might be helpful if the guessing method does not work well for
656 - Added support for stacked labels, upper case X/B in hex and binary, and
659 - Eliminated warning messages for using keyword names as constants.
662 - Corrected problem introduced by using a chomp on scalar references, RT #77978
664 - Added support for Perl 5.14 package block syntax, RT #78114.
666 - A convergence test is made if three or more iterations are requested with
667 the -it=n parameter to avoid wasting computer time. Several hundred Mb of
668 code gleaned from the internet were searched with the results that:
669 - It is unusual for two iterations to be required unless a major
670 style change is being made.
671 - Only one case has been found where three iterations were required.
672 - No cases requiring four iterations have been found with this version.
673 For the previous version several cases where found the results could
674 oscillate between two semi-stable states. This version corrects this.
676 So if it is important that the code be converged it is okay to set -it=4
677 with this version and it will probably stop after the second iteration.
679 - Improved ability to identify and retain good line break points in the
680 input stream, such as at commas and equals. You can always tell
681 perltidy to ignore old breakpoints with -iob.
683 - Fixed glitch in which a terminal closing hash brace followed by semicolon
684 was not outdented back to the leading line depth like other closing
685 tokens. Thanks to Keith Neargarder for noting this.
688 my ( $pre, $post ) = @{
690 "pp_anonlist" => [ "[", "]" ],
691 "pp_anonhash" => [ "{", "}" ]
696 my ( $pre, $post ) = @{
698 "pp_anonlist" => [ "[", "]" ],
699 "pp_anonhash" => [ "{", "}" ]
703 - Removed extra indentation given to trailing 'if' and 'unless' clauses
704 without parentheses because this occasionally produced undesirable
705 results. This only applies where parens are not used after the if or
710 unless my ( $who, $actions ) =
711 $clause =~ /^($who_re)((?:$action_re)+)$/o;
715 unless my ( $who, $actions ) =
716 $clause =~ /^($who_re)((?:$action_re)+)$/o;
719 - Updated perltidy to handle all quote modifiers defined for perl 5 version 16.
721 - Side comment text in perltidyrc configuration files must now begin with
722 at least one space before the #. Thus:
725 -l=78 # Max line width is 78 cols
727 -l=78# Max line width is 78 cols
729 This is probably true of almost all existing perltidyrc files,
730 but if you get an error message about bad parameters
731 involving a '#' the first time you run this version, please check the side
732 comments in your perltidyrc file, and add a space before the # if necessary.
733 You can quickly see the contents your perltidyrc file, if any, with the
738 The reason for this change is that some parameters naturally involve
739 the # symbol, and this can get interpreted as a side comment unless the
740 parameter is quoted. For example, to define -sphb=# it used to be necessary
743 to keep the # from becoming part of a comment. This was causing
744 trouble for new users. Now it can also be written without quotes:
747 - Fixed bug in processing some .perltidyrc files containing parameters with
748 an opening brace character, '{'. For example the following was
749 incorrectly processed:
750 --static-block-comment-prefix="^#{2,}[^\s#]"
753 - Added flag -boa (--break-at-old-attribute-breakpoints) which retains
754 any existing line breaks at attribute separation ':'. This is now the
755 default, use -nboa to deactivate. Thanks to Daphne Phister for the patch.
756 For example, given the following code, the line breaks at the ':'s will be
762 : Get('Name' => 'foo') : Set('Name');
764 whereas the previous version would have output a single line. If
765 the attributes are on a single line then they will remain on a single line.
767 - Added new flags --blank-lines-before-subs=n (-blbs=n) and
768 --blank-lines-before-packages=n (-blbp=n) to put n blank lines before
769 subs and packages. The old flag -bbs is now equivalent to -blbs=1 -blbp=1.
770 and -nbbs is equivalent to -blbs=0 -blbp=0. Requested by M. Schwern and
773 - Added feature -nsak='*' meaning no space between any keyword and opening
774 paren. This avoids listing entering a long list of keywords. Requested
777 - Added option to delete a backup of original file with in-place-modify (-b)
778 if there were no errors. This can be requested with the flag -bext='/'.
779 See documentation for details. Requested by M. Schwern and others.
781 - Fixed bug where the module postfilter parameter was not applied when -b
782 flag was used. This was discovered during testing.
784 - Fixed in-place-modify (-b) to work with symbolic links to source files.
785 Thanks to Ted Johnson.
787 - Fixed bug where the Perl::Tidy module did not allow -b to be used
790 - No extra blank line is added before a comment which follows
791 a short line ending in an opening token, for example like this:
795 # unless we follow a blank or comment line
796 $last_line_leading_type !~ /^[#b]$/
801 # unless we follow a blank or comment line
802 $last_line_leading_type !~ /^[#b]$/
805 The blank is not needed for readability in these cases because there
806 already is already space above the comment. If a blank already
807 exists there it will not be removed, so this change should not
808 change code which has previously been formatted with perltidy.
809 Thanks to R.W.Stauner.
811 - Likewise, no extra blank line is added above a comment consisting of a
812 single #, since nothing is gained in readability.
814 - Fixed error in which a blank line was removed after a #>>> directive.
815 Thanks to Ricky Morse.
817 - Unnecessary semicolons after given/when/default blocks are now removed.
819 - Fixed bug where an unwanted blank line could be added before
820 pod text in __DATA__ or __END__ section. Thanks to jidani.
822 - Changed exit flags from 1 to 0 to indicate success for -help, -version,
823 and all -dump commands. Also added -? as another way to dump the help.
824 Requested by Keith Neargarder.
826 - Fixed bug where .ERR and .LOG files were not written except for -it=2 or more
828 - Fixed bug where trailing blank lines at the end of a file were dropped when
831 - Fixed bug where a line occasionally ended with an extra space. This reduces
832 rhe number of instances where a second iteration gives a result different
835 - Updated documentation to note that the Tidy.pm module <stderr> parameter may
836 not be a reference to SCALAR or ARRAY; it must be a file.
838 - Syntax check with perl now work when the Tidy.pm module is processing
839 references to arrays and strings. Thanks to Charles Alderman.
841 - Zero-length files are no longer processed due to concerns for data loss
842 due to side effects in some scenarios.
844 - block labels, if any, are now included in closing side comment text
845 when the -csc flag is used. Suggested by Aaron. For example,
846 the label L102 in the following block is now included in the -csc text:
848 L102: for my $i ( 1 .. 10 ) {
850 } ## end L102: for my $i ( 1 .. 10 )
853 - added new flag -it=n or --iterations=n
854 This flag causes perltidy to do n complete iterations.
855 For most purposes the default of n=1 should be satisfactory. However n=2
856 can be useful when a major style change is being made, or when code is being
857 beautified on check-in to a source code control system. The run time will be
858 approximately proportional to n, and it should seldom be necessary to use a
859 value greater than n=2. Thanks to Jonathan Swartz
861 - A configuration file pathname begins with three dots, e.g.
862 ".../.perltidyrc", indicates that the file should be searched for starting
863 in the current directory and working upwards. This makes it easier to have
864 multiple projects each with their own .perltidyrc in their root directories.
865 Thanks to Jonathan Swartz for this patch.
867 - Added flag --notidy which disables all formatting and causes the input to be
868 copied unchanged. This can be useful in conjunction with hierarchical
869 F<.perltidyrc> files to prevent unwanted tidying.
870 Thanks to Jonathan Swartz for this patch.
872 - Added prefilters and postfilters in the call to the Tidy.pm module.
873 Prefilters and postfilters. The prefilter is a code reference that
874 will be applied to the source before tidying, and the postfilter
875 is a code reference to the result before outputting.
877 Thanks to Jonathan Swartz for this patch. He writes:
878 This is useful for all manner of customizations. For example, I use
879 it to convert the 'method' keyword to 'sub' so that perltidy will work for
880 Method::Signature::Simple code:
882 Perl::Tidy::perltidy(
883 prefilter => sub { $_ = $_[0]; s/^method (.*)/sub $1 \#__METHOD/gm; return $_ },
884 postfilter => sub { $_ = $_[0]; s/^sub (.*?)\s* \#__METHOD/method $1/gm; return $_ }
887 - The starting indentation level of sections of code entabbed with -et=n
888 is correctly guessed if it was also produced with the same -et=n flag. This
889 keeps the indentation stable on repeated formatting passes within an editor.
890 Thanks to Sam Kington and Glenn.
892 - Functions with prototype '&' had a space between the function and opening
893 peren. This space now only occurs if the flag --space-function-paren (-sfp)
894 is set. Thanks to Zrajm Akfohg.
896 - Patch to never put spaces around a bare word in braces beginning with ^ as in:
897 my $before = ${^PREMATCH};
898 even if requested with the -bt=0 flag because any spaces cause a syntax error in perl.
899 Thanks to Fabrice Dulanoy.
902 - Allow configuration file to be 'perltidy.ini' for Windows systems.
903 i.e. C:\Documents and Settings\User\perltidy.ini
904 and added documentation for setting configuation file under Windows in man
905 page. Thanks to Stuart Clark.
907 - Corrected problem of unwanted semicolons in hash ref within given/when code.
908 Thanks to Nelo Onyiah.
910 - added new flag -cscb or --closing-side-comments-balanced
911 When using closing-side-comments, and the closing-side-comment-maximum-text
912 limit is exceeded, then the comment text must be truncated. Previous
913 versions of perltidy terminate with three dots, and this can still be
914 achieved with -ncscb:
918 } ## end foreach my $foo (sort { $b cmp $a ...
920 However this causes a problem with older editors which cannot recognize
921 comments or are not configured to doso because they cannot "bounce" around in
922 the text correctly. The B<-cscb> flag tries to help them by
923 appending appropriate terminal balancing structure:
927 } ## end foreach my $foo (sort { $b cmp $a ... })
929 Since there is much to be gained and little to be lost by doing this,
930 the default is B<-cscb>. Use B<-ncscb> if you do not want this.
932 Thanks to Daniel Becker for suggesting this option.
934 - After an isolated closing eval block the continuation indentation will be
935 removed so that the braces line up more like other blocks. Thanks to Yves Orton.
954 -A new flag -asbl (or --opening-anonymous-sub-brace-on-new-line) has
955 been added to put the opening brace of anonymous sub's on a new line,
956 as in the following snippet:
964 This was not possible before because the -sbl flag only applies to named
965 subs. Thanks to Benjamin Krupp.
967 -Fix tokenization bug with the following snippet
968 print 'hi' if { x => 1, }->{x};
969 which resulted in a semicolon being added after the comma. The workaround
970 was to use -nasc, but this is no longer necessary. Thanks to Brian Duggan.
972 -Fixed problem in which an incorrect error message could be triggered
973 by the (unusual) combination of parameters -lp -i=0 -l=2 -ci=0 for
974 example. Thanks to Richard Jelinek.
976 -A new flag --keep-old-blank-lines=n has been added to
977 give more control over the treatment of old blank lines in
978 a script. The manual has been revised to discuss the new
979 flag and clarify the treatment of old blank lines. Thanks
983 -Improved support for perl 5.10: New quote modifier 'p', new block type UNITCHECK,
984 new keyword break, improved formatting of given/when.
986 -Corrected tokenization bug of something like $var{-q}.
988 -Numerous minor formatting improvements.
990 -Corrected list of operators controlled by -baao -bbao to include
991 . : ? && || and or err xor
993 -Corrected very minor error in log file involving incorrect comment
994 regarding need for upper case of labels.
996 -Fixed problem where perltidy could run for a very long time
997 when given certain non-perl text files.
999 -Line breaks in un-parenthesized lists now try to follow
1000 line breaks in the input file rather than trying to fill
1001 lines. This usually works better, but if this causes
1002 trouble you can use -iob to ignore any old line breaks.
1003 Example for the following input snippet:
1006 "conformability (Not the same dimension)\n",
1007 "\t", $have, " is ", text_unit($hu), "\n",
1008 "\t", $want, " is ", text_unit($wu), "\n",
1012 print "conformability (Not the same dimension)\n", "\t", $have, " is ",
1013 text_unit($hu), "\n", "\t", $want, " is ", text_unit($wu), "\n",;
1016 print "conformability (Not the same dimension)\n",
1017 "\t", $have, " is ", text_unit($hu), "\n",
1018 "\t", $want, " is ", text_unit($wu), "\n",
1022 -Added -fpsc option (--fixed-position-side-comment). Thanks to Ueli Hugenschmidt.
1023 For example -fpsc=40 tells perltidy to put side comments in column 40
1026 -Added -bbao and -baao options (--break-before-all-operators and
1027 --break-after-all-operators) to simplify command lines and configuration
1028 files. These define an initial preference for breaking at operators which can
1029 be modified with -wba and -wbb flags. For example to break before all operators
1030 except an = one could use --bbao -wba='=' rather than listing every
1031 single perl operator (except =) on a -wbb flag.
1033 -Added -kis option (--keep-interior-semicolons). Use the B<-kis> flag
1034 to prevent breaking at a semicolon if there was no break there in the
1035 input file. To illustrate, consider the following input lines:
1037 dbmclose(%verb_delim); undef %verb_delim;
1038 dbmclose(%expanded); undef %expanded;
1039 dbmclose(%global); undef %global;
1041 Normally these would be broken into six lines, but
1042 perltidy -kis gives:
1044 dbmclose(%verb_delim); undef %verb_delim;
1045 dbmclose(%expanded); undef %expanded;
1046 dbmclose(%global); undef %global;
1048 -Improved formatting of complex ternary statements, with indentation
1049 of nested statements.
1051 return defined( $cw->{Selected} )
1053 ? @{ $cw->{Selected} }
1054 : $cw->{Selected}[0]
1058 return defined( $cw->{Selected} )
1060 ? @{ $cw->{Selected} }
1061 : $cw->{Selected}[0]
1064 -Text following un-parenthesized if/unless/while/until statements get a
1065 full level of indentation. Suggested by Jeff Armstorng and others.
1067 return $ship->chargeWeapons("phaser-canon")
1068 if $encounter->description eq 'klingon'
1069 and $ship->firepower >= $encounter->firepower
1070 and $location->status ne 'neutral';
1072 return $ship->chargeWeapons("phaser-canon")
1073 if $encounter->description eq 'klingon'
1074 and $ship->firepower >= $encounter->firepower
1075 and $location->status ne 'neutral';
1078 -Fixed bug where #line directives were being indented. Thanks to
1082 -Fixed problem where an extra blank line was added after an =cut when either
1083 (a) the =cut started (not stopped) a POD section, or (b) -mbl > 1.
1084 Thanks to J. Robert Ray and Bill Moseley.
1087 -ole (--output-line-ending) and -ple (--preserve-line-endings) should
1088 now work on all systems rather than just unix systems. Thanks to Dan
1091 -Fixed problem of a warning issued for multiple subs for BEGIN subs
1092 and other control subs. Thanks to Heiko Eissfeldt.
1094 -Fixed problem where no space was introduced between a keyword or
1095 bareword and a colon, such as:
1097 ( ref($result) eq 'HASH' && !%$result ) ? undef: $result;
1101 -Added a utility program 'break_long_quotes.pl' to the examples directory of
1102 the distribution. It breaks long quoted strings into a chain of concatenated
1103 sub strings no longer than a selected length. Suggested by Michael Renner as
1104 a perltidy feature but was judged to be best done in a separate program.
1106 -Updated docs to remove extra < and >= from list of tokens
1107 after which breaks are made by default. Thanks to Bob Kleemann.
1109 -Removed improper uses of $_ to avoid conflicts with external calls, giving
1110 error message similar to:
1111 Modification of a read-only value attempted at
1112 /usr/share/perl5/Perl/Tidy.pm line 6907.
1113 Thanks to Michael Renner.
1115 -Fixed problem when errorfile was not a plain filename or filehandle
1116 in a call to Tidy.pm. The call
1117 perltidy(source => \$input, destination => \$output, errorfile => \$err);
1118 gave the following error message:
1119 Not a GLOB reference at /usr/share/perl5/Perl/Tidy.pm line 3827.
1120 Thanks to Michael Renner and Phillipe Bruhat.
1122 -Fixed problem where -sot would not stack an opening token followed by
1123 a side comment. Thanks to Jens Schicke.
1125 -improved breakpoints in complex math and other long statements. Example:
1128 log($n) + 0.577215664901532 + ( 1 / ( 2 * $n ) ) -
1129 ( 1 / ( 12 * ( $n**2 ) ) ) + ( 1 / ( 120 * ( $n**4 ) ) );
1132 log($n) + 0.577215664901532 +
1133 ( 1 / ( 2 * $n ) ) -
1134 ( 1 / ( 12 * ( $n**2 ) ) ) +
1135 ( 1 / ( 120 * ( $n**4 ) ) );
1137 -more robust vertical alignment of complex terminal else blocks and ternary
1141 -Eliminated bug where a here-doc invoked through an 'e' modifier on a pattern
1142 replacement text was not recognized. The tokenizer now recursively scans
1143 replacement text (but does not reformat it).
1145 -improved vertical alignment of terminal else blocks and ternary statements.
1146 Thanks to Chris for the suggestion.
1149 if ( IsBitmap() ) { return GetBitmap(); }
1150 elsif ( IsFiles() ) { return GetFiles(); }
1151 else { return GetText(); }
1154 if ( IsBitmap() ) { return GetBitmap(); }
1155 elsif ( IsFiles() ) { return GetFiles(); }
1156 else { return GetText(); }
1160 $opts{"t"} ? 'title'
1161 : $opts{"s"} ? 'subject'
1162 : $opts{"a"} ? 'author'
1167 $opts{"t"} ? 'title'
1168 : $opts{"s"} ? 'subject'
1169 : $opts{"a"} ? 'author'
1172 -improved indentation of try/catch blocks and other externally defined
1173 functions accepting a block argument. Thanks to jae.
1175 -Added support for Perl 5.10 features say and smartmatch.
1177 -Added flag -pbp (--perl-best-practices) as an abbreviation for parameters
1178 suggested in Damian Conway's "Perl Best Practices". -pbp is the same as:
1180 -l=78 -i=4 -ci=4 -st -se -vt=2 -cti=0 -pt=1 -bt=1 -sbt=1 -bbt=1 -nsfs -nolq
1181 -wbb="% + - * / x != == >= <= =~ !~ < > | & >= < =
1182 **= += *= &= <<= &&= -= /= |= >>= ||= .= %= ^= x="
1184 Please note that the -st here restricts input to standard input; use
1185 -nst if necessary to override.
1187 -Eliminated some needless breaks at equals signs in -lp indentation.
1191 Math::Complex->make(LEFT + $x * (RIGHT - LEFT) / SIZE,
1192 TOP + $y * (BOTTOM - TOP) / SIZE);
1194 $c = Math::Complex->make(LEFT + $x * (RIGHT - LEFT) / SIZE,
1195 TOP + $y * (BOTTOM - TOP) / SIZE);
1197 A break at an equals is sometimes useful for preventing complex statements
1198 from hitting the line length limit. The decision to do this was
1199 over-eager in some cases and has been improved. Thanks to Royce Reece.
1201 -qw quotes contained in braces, square brackets, and parens are being
1202 treated more like those containers as far as stacking of tokens. Also
1203 stack of closing tokens ending ');' will outdent to where the ');' would
1204 have outdented if the closing stack is matched with a similar opening stack.
1206 OLD: perltidy -soc -sct
1207 __PACKAGE__->load_components(
1213 NEW: perltidy -soc -sct
1214 __PACKAGE__->load_components( qw(
1218 Thanks to Aran Deltac
1220 -Eliminated some undesirable or marginally desirable vertical alignments.
1221 These include terminal colons, opening braces, and equals, and particularly
1222 when just two lines would be aligned.
1225 my $accurate_timestamps = $Stamps{lnk};
1229 my $accurate_timestamps = $Stamps{lnk};
1232 -Corrected a problem with -mangle in which a space would be removed
1233 between a keyword and variable beginning with ::.
1236 -Attribute argument lists are now correctly treated as quoted strings
1237 and not formatted. This is the most important update in this version.
1238 Thanks to Borris Zentner, Greg Ferguson, Steve Kirkup.
1240 -Updated to recognize the defined or operator, //, to be released in Perl 10.
1241 Thanks to Sebastien Aperghis-Tramoni.
1243 -A useful utility perltidyrc_dump.pl is included in the examples section. It
1244 will read any perltidyrc file and write it back out in a standard format
1245 (though comments are lost).
1247 -Added option to have perltidy read and return a hash with the contents of a
1248 perltidyrc file. This may be used by Leif Eriksen's tidyview code. This
1249 feature is used by the demonstration program 'perltidyrc_dump.pl' in the
1252 -Improved error checking in perltidyrc files. Unknown bare words were not
1255 -The --dump-options parameter now dumps parameters in the format required by a
1258 -V-Strings with underscores are now recognized.
1259 For example: $v = v1.2_3;
1261 -cti=3 option added which gives one extra indentation level to closing
1262 tokens always. This provides more predictable closing token placement
1263 than cti=2. If you are using cti=2 you might want to try cti=3.
1265 -To identify all left-adjusted comments as static block comments, use C<-sbcp='^#'>.
1267 -New parameters -fs, -fsb, -fse added to allow sections of code between #<<<
1268 and #>>> to be passed through verbatim. This is enabled by default and turned
1269 off by -nfs. Flags -fsb and -fse allow other beginning and ending markers.
1270 Thanks to Wolfgang Werner and Marion Berryman for suggesting this.
1272 -added flag -skp to put a space between all Perl keywords and following paren.
1273 The default is to only do this for certain keywords. Suggested by
1276 -added flag -sfp to put a space between a function name and following paren.
1277 The default is not to do this. Suggested by H.Merijn Brand.
1279 -Added patch to avoid breaking GetOpt::Long::Configure set by calling program.
1280 Thanks to Philippe Bruhat.
1282 -An error was fixed in which certain parameters in a .perltidyrc file given
1283 without the equals sign were not recognized. That is,
1284 '--brace-tightness 0' gave an error but '--brace-tightness=0' worked
1285 ok. Thanks to Zac Hansen.
1287 -An error preventing the -nwrs flag from working was corrected. Thanks to
1290 -Corrected some alignment problems with entab option.
1292 -A bug with the combination of -lp and -extrude was fixed (though this
1293 combination doesn't really make sense). The bug was that a line with
1294 a single zero would be dropped. Thanks to Cameron Hayne.
1296 -Updated Windows detection code to avoid an undefined variable.
1297 Thanks to Joe Yates and Russ Jones.
1299 -Improved formatting for short trailing statements following a closing paren.
1300 Thanks to Joe Matarazzo.
1302 -The handling of the -icb (indent closing block braces) flag has been changed
1303 slightly to provide more consistent and predictable formatting of complex
1304 structures. Instead of giving a closing block brace the indentation of the
1305 previous line, it is now given one extra indentation level. The two methods
1306 give the same result if the previous line was a complete statement, as in this
1315 The change also fixes a problem with empty blocks such as:
1325 -A problem with -icb was fixed in which a closing brace was misplaced when
1326 it followed a quote which spanned multiple lines.
1328 -Some improved breakpoints for -wba='&& || and or'
1330 -Fixed problem with misaligned cuddled else in complex statements
1331 when the -bar flag was also used. Thanks to Alex and Royce Reese.
1333 -Corrected documentation to show that --outdent-long-comments is the default.
1334 Thanks to Mario Lia.
1336 -New flag -otr (opening-token-right) is similar to -bar (braces-always-right)
1337 but applies to non-structural opening tokens.
1339 -new flags -sot (stack-opening-token), -sct (stack-closing-token).
1343 -The default has been changed to not do syntax checking with perl.
1344 Use -syn if you want it. Perltidy is very robust now, and the -syn
1345 flag now causes more problems than it's worth because of BEGIN blocks
1346 (which get executed with perl -c). For example, perltidy will never
1347 return when trying to beautify this code if -syn is used:
1349 BEGIN { 1 while { }; }
1351 Although this is an obvious error, perltidy is often run on untested
1352 code which is more likely to have this sort of problem. A more subtle
1355 BEGIN { use FindBin; }
1357 which may hang on some systems using -syn if a shared file system is
1360 -Changed style -gnu to use -cti=1 instead of -cti=2 (see next item).
1361 In most cases it looks better. To recover the previous format, use
1364 -Added flags -cti=n for finer control of closing token indentation.
1365 -cti = 0 no extra indentation (default; same as -nicp)
1366 -cti = 1 enough indentation so that the closing token
1367 aligns with its opening token.
1368 -cti = 2 one extra indentation level if the line has the form
1369 ); ]; or }; (same as -icp).
1371 The new option -cti=1 works well with -lp:
1375 # perltidy -lp -cti=1
1377 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
1378 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
1381 # perltidy -lp -cti=2
1383 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
1384 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
1386 This is backwards compatible with -icp. See revised manual for
1387 details. Suggested by Mike Pennington.
1389 -Added flag '--preserve-line-endings' or '-ple' to cause the output
1390 line ending to be the same as in the input file, for unix, dos,
1391 or mac line endings. Only works under unix. Suggested by
1394 -Added flag '--output-line-ending=s' or '-ole=s' where s=dos or win,
1395 unix, or mac. Only works under unix.
1397 -Files with Mac line endings should now be handled properly under unix
1398 and dos without being passed through a converter.
1400 -You may now include 'and', 'or', and 'xor' in the list following
1401 '--want-break-after' to get line breaks after those keywords rather than
1402 before them. Suggested by Rainer Hochschild.
1404 -Corrected problem with command line option for -vtc=n and -vt=n. The
1405 equals sign was being eaten up by the Windows shell so perltidy didn't
1409 -Corrected cause of warning message with recent versions of Perl:
1410 "Possible precedence problem on bitwise & operator at ..."
1411 Thanks to Jim Files.
1413 -fixed bug with -html with '=for pod2html' sections, in which code/pod
1414 output order was incorrect. Thanks to Tassilo von Parseval.
1416 -fixed bug when the -html flag is used, in which the following error
1417 message, plus others, appear:
1418 did not see <body> in pod2html output
1419 This was caused by a change in the format of html output by pod2html
1420 VERSION 1.04 (included with perl 5.8). Thanks to Tassilo von Parseval.
1422 -Fixed bug where an __END__ statement would be mistaken for a label
1423 if it is immediately followed by a line with a leading colon. Thanks
1426 -Implemented guessing logic for brace types when it is ambiguous. This
1427 has been on the TODO list a long time. Thanks to Boris Zentner for
1430 -Long options may now be negated either as '--nolong-option'
1431 or '--no-long-option'. Thanks to Philip Newton for the suggestion.
1433 -added flag --html-entities or -hent which controls the use of
1434 Html::Entities for html formatting. Use --nohtml-entities or -nhent to
1435 prevent the use of Html::Entities to encode special symbols. The
1436 default is -hent. Html::Entities when formatting perl text to escape
1437 special symbols. This may or may not be the right thing to do,
1438 depending on browser/language combinations. Thanks to Burak Gursoy for
1441 -Bareword strings with leading '-', like, '-foo' now count as 1 token
1442 for horizontal tightness. This way $a{'-foo'}, $a{foo}, and $a{-foo}
1443 are now all treated similarly. Thus, by default, OLD: $a{ -foo } will
1444 now be NEW: $a{-foo}. Suggested by Mark Olesen.
1446 -added 2 new flags to control spaces between keywords and opening parens:
1447 -sak=s or --space-after-keyword=s, and
1448 -nsak=s or --nospace-after-keyword=s, where 's' is a list of keywords.
1450 The new default list of keywords which get a space is:
1452 "my local our and or eq ne if else elsif until unless while for foreach
1453 return switch case given when"
1455 Use -sak=s and -nsak=s to add and remove keywords from this list,
1458 Explanation: Stephen Hildrey noted that perltidy was being inconsistent
1459 in placing spaces between keywords and opening parens, and sent a patch
1460 to give user control over this. The above list was selected as being
1461 a reasonable default keyword list. Previously, perltidy
1462 had a hardwired list which also included these keywords:
1464 push pop shift unshift join split die
1466 but did not have 'our'. Example: if you prefer to make perltidy behave
1467 exactly as before, you can include the following two lines in your
1470 -sak="push pop local shift unshift join split die"
1473 -Corrected html error in .toc file when -frm -html is used (extra ");
1474 browsers were tolerant of it.
1476 -Improved alignment of chains of binary and ?/: operators. Example:
1490 -improved breakpoint choices involving '->'
1492 -Corrected tokenization of things like ${#}. For example,
1493 ${#} is valid, but ${# } is a syntax error.
1495 -Corrected minor tokenization errors with indirect object notation.
1496 For example, 'new A::()' works now.
1498 -Minor tokenization improvements; all perl code distributed with perl 5.8
1499 seems to be parsed correctly except for one instance (lextest.t)
1503 -Implemented scalar attributes. Thanks to Sean Tobin for noting this.
1505 -Fixed glitch introduced in previous release where -pre option
1506 was not outputting a leading html <pre> tag.
1508 -Numerous minor improvements in vertical alignment, including the following:
1510 -Improved alignment of opening braces in many cases. Needed for improved
1511 switch/case formatting, and also suggested by Mark Olesen for sort/map/grep
1512 formatting. For example:
1517 sort { $a->[1] <=> $b->[1] }
1518 map { [ $_, -M ] } @filenames;
1523 sort { $a->[1] <=> $b->[1] }
1524 map { [ $_, -M ] } @filenames;
1526 -Eliminated alignments across unrelated statements. Example:
1528 $borrowerinfo->configure( -state => 'disabled' );
1529 $borrowerinfo->grid( -col => 1, -row => 0, -sticky => 'w' );
1532 $borrowerinfo->configure( -state => 'disabled' );
1533 $borrowerinfo->grid( -col => 1, -row => 0, -sticky => 'w' );
1535 Thanks to Mark Olesen for suggesting this.
1537 -Improved alignement of '='s in certain cases.
1538 Thanks to Norbert Gruener for sending an example.
1540 -Outdent-long-comments (-olc) has been re-instated as a default, since
1541 it works much better now. Use -nolc if you want to prevent it.
1543 -Added check for 'perltidy file.pl -o file.pl', which causes file.pl
1544 to be lost. (The -b option should be used instead). Thanks to mreister
1545 for reporting this problem.
1548 -Switch/case or given/when syntax is now recognized. Its vertical alignment
1549 is not great yet, but it parses ok. The words 'switch', 'case', 'given',
1550 and 'when' are now treated as keywords. If this causes trouble with older
1551 code, we could introduce a switch to deactivate it. Thanks to Stan Brown
1552 and Jochen Schneider for recommending this.
1554 -Corrected error parsing sub attributes with call parameters.
1555 Thanks to Marc Kerr for catching this.
1557 -Sub prototypes no longer need to be on the same line as sub names.
1559 -a new flag -frm or --frames will cause html output to be in a
1560 frame, with table of contents in the left panel and formatted source
1561 in the right panel. Try 'perltidy -html -frm somemodule.pm' for example.
1563 -The new default for -html formatting is to pass the pod through Pod::Html.
1564 The result is syntax colored code within your pod documents. This can be
1565 deactivated with -npod. Thanks to those who have written to discuss this,
1566 particularly Mark Olesen and Hugh Myers.
1568 -the -olc (--outdent-long-comments) option works much better. It now outdents
1569 groups of consecutive comments together, and by just the amount needed to
1570 avoid having any one line exceeding the maximum line length.
1572 -block comments are now trimmed of trailing whitespace.
1574 -if a directory specified with -opath does not exist, it will be created.
1576 -a table of contents to packages and subs is output when -html is used.
1577 Use -ntoc to prevent this.
1579 -fixed an unusual bug in which a 'for' statement following a 'format'
1580 statement was not correctly tokenized. Thanks to Boris Zentner for
1583 -Tidy.pm is no longer dependent on modules IO::Scalar and IO::ScalarArray.
1584 There were some speed issues. Suggested by Joerg Walter.
1586 -The treatment of quoted wildcards (file globs) is now system-independent.
1589 perltidy 'b*x.p[lm]'
1591 would match box.pl, box.pm, brinx.pm under any operating system. Of
1592 course, anything unquoted will be subject to expansion by any shell.
1594 -default color for keywords under -html changed from
1595 SaddleBrown (#8B4513) to magenta4 (#8B008B).
1597 -fixed an arg parsing glitch in which something like:
1599 would trigger the help message and exit, rather than operate on the
1603 -New option '-b' or '--backup-and-modify-in-place' will cause perltidy to
1604 overwrite the original file with the tidied output file. The original
1605 file will be saved with a '.bak' extension (which can be changed with
1606 -bext=s). Thanks to Rudi Farkas for the suggestion.
1608 -An index to all subs is included at the top of -html output, unless
1609 only the <pre> section is written.
1611 -Anchor lines of the form <a name="mysub"></a> are now inserted at key points
1612 in html output, such as before sub definitions, for the convenience of
1613 postprocessing scripts. Suggested by Howard Owen.
1615 -The cuddled-else (-ce) flag now also makes cuddled continues, like
1618 while ( ( $pack, $file, $line ) = caller( $i++ ) ) {
1624 Suggested by Simon Perreault.
1626 -Fixed bug in which an extra blank line was added before an =head or
1627 similar pod line after an __END__ or __DATA__ line each time
1628 perltidy was run. Also, an extra blank was being added after
1629 a terminal =cut. Thanks to Mike Birdsall for reporting this.
1632 -Fixed bug in which space was inserted in a hyphenated hash key:
1633 my $val = $myhash{USER-NAME};
1635 my $val = $myhash{USER -NAME};
1636 Thanks to an anonymous bug reporter at sourceforge.
1638 -Fixed problem with the '-io' ('--indent-only') where all lines
1639 were double spaced. Thanks to Nick Andrew for reporting this bug.
1641 -Fixed tokenization error in which something like '-e1' was
1644 -Corrected a rare problem involving older perl versions, in which
1645 a line break before a bareword caused problems with 'use strict'.
1646 Thanks to Wolfgang Weisselberg for noting this.
1648 -More syntax error checking added.
1650 -Outdenting labels (-ola) has been made the default, in order to follow the
1651 perlstyle guidelines better. It's probably a good idea in general, but
1652 if you do not want this, use -nola in your .perltidyrc file.
1654 -Updated rules for padding logical expressions to include more cases.
1655 Thanks to Wolfgang Weisselberg for helpful discussions.
1657 -Added new flag -osbc (--outdent-static-block-comments) which will
1658 outdent static block comments by 2 spaces (or whatever -ci equals).
1659 Requested by Jon Robison.
1662 -Corrected a bug, introduced in the previous release, in which some
1663 closing side comments (-csc) could have incorrect text. This is
1664 annoying but will be correct the next time perltidy is run with -csc.
1666 -Implemented XHTML patch submitted by Ville Skyttä.
1668 -Fixed bug where whitespace was being removed between 'Bar' and '()'
1669 in a use statement like:
1673 Thanks to Ville Skyttä for reporting this.
1675 -Whenever possible, if a logical expression is broken with leading
1676 '&&', '||', 'and', or 'or', then the leading line will be padded
1677 with additional space to produce alignment. This has been on the
1678 todo list for a long time; thanks to Frank Steinhauer for reminding
1679 me to do it. Notice the first line after the open parens here:
1683 !param("rules.to.$linecount")
1684 && !param("rules.from.$linecount")
1685 && !param("rules.subject.$linecount")
1687 param("rules.fieldname.$linecount")
1688 && param("rules.fieldval.$linecount")
1690 && !param("rules.size.$linecount")
1691 && !param("rules.custom.$linecount")
1696 !param("rules.to.$linecount")
1697 && !param("rules.from.$linecount")
1698 && !param("rules.subject.$linecount")
1700 param("rules.fieldname.$linecount")
1701 && param("rules.fieldval.$linecount")
1703 && !param("rules.size.$linecount")
1704 && !param("rules.custom.$linecount")
1708 -Corrected a mistokenization of variables for a package with a name
1709 equal to a perl keyword. For example:
1713 sub qx{print "Hello from my::qx\n";}
1715 In this case, the leading 'my' was mistokenized as a keyword, and a
1716 space was being place between 'my' and '::'. This has been
1717 corrected. Thanks to Martin Sluka for discovering this.
1719 -A new flag -bol (--break-at-old-logic-breakpoints)
1720 has been added to control whether containers with logical expressions
1721 should be broken open. This is the default.
1723 -A new flag -bok (--break-at-old-keyword-breakpoints)
1724 has been added to follow breaks at old keywords which return lists,
1725 such as sort and map. This is the default.
1727 -A new flag -bot (--break-at-old-trinary-breakpoints) has been added to
1728 follow breaks at trinary (conditional) operators. This is the default.
1730 -A new flag -cab=n has been added to control breaks at commas after
1731 '=>' tokens. The default is n=1, meaning break unless this breaks
1732 open an existing on-line container.
1734 -A new flag -boc has been added to allow existing list formatting
1735 to be retained. (--break-at-old-comma-breakpoints). See updated manual.
1737 -A new flag -iob (--ignore-old-breakpoints) has been added to
1738 prevent the locations of old breakpoints from influencing the output
1741 -Corrected problem where nested parentheses were not getting full
1742 indentation. This has been on the todo list for some time; thanks
1743 to Axel Rose for a snippet demonstrating this issue.
1745 OLD: inner list is not indented
1749 $ret->name, $user->username, $user->host,
1750 $user->server->name, $user->nick, "H"
1758 $ret->name, $user->username, $user->host,
1759 $user->server->name, $user->nick, "H"
1763 -Code cleaned up by removing the following unused, undocumented flags.
1764 They should not be in any .perltidyrc files because they were just
1765 experimental flags which were never documented. Most of them placed
1766 artificial limits on spaces, and Wolfgang Weisselberg convinced me that
1767 most of them they do more harm than good by causing unexpected results.
1769 --maximum-continuation-indentation (-mci)
1770 --maximum-whitespace-columns
1771 --maximum-space-to-comment (-xsc)
1772 --big-space-jump (-bsj)
1774 -Pod file 'perltidy.pod' has been appended to the script 'perltidy', and
1775 Tidy.pod has been append to the module 'Tidy.pm'. Older MakeMaker's
1776 were having trouble.
1778 -A new flag -isbc has been added for more control on comments. This flag
1779 has the effect that if there is no leading space on the line, then the
1780 comment will not be indented, and otherwise it may be. If both -ibc and
1781 -isbc are set, then -isbc takes priority. Thanks to Frank Steinhauer
1782 for suggesting this.
1784 -A new document 'stylekey.pod' has been created to quickly guide new users
1785 through the maze of perltidy style parameters. An html version is
1786 on the perltidy web page. Take a look! It should be very helpful.
1788 -Parameters for controlling 'vertical tightness' have been added:
1789 -vt and -vtc are the main controls, but finer control is provided
1790 with -pvt, -pcvt, -bvt, -bcvt, -sbvt, -sbcvt. Block brace vertical
1791 tightness controls have also been added.
1792 See updated manual and also see 'stylekey.pod'. Simple examples:
1794 # perltidy -lp -vt=1 -vtc=1
1795 @month_of_year = ( 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
1796 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec' );
1798 # perltidy -lp -vt=1 -vtc=0
1799 @month_of_year = ( 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
1800 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
1803 -Lists which do not format well in uniform columns are now better
1804 identified and formated.
1807 return $c->create( 'polygon', $x, $y, $x + $ruler_info{'size'},
1808 $y + $ruler_info{'size'}, $x - $ruler_info{'size'},
1809 $y + $ruler_info{'size'} );
1814 $x + $ruler_info{'size'},
1815 $y + $ruler_info{'size'},
1816 $x - $ruler_info{'size'},
1817 $y + $ruler_info{'size'}
1821 radlablist($f1, pad('Initial', $p), $b->{Init}->get_panel_ref, 'None ',
1822 'None', 'Default', 'Default', 'Simple', 'Simple');
1826 $b->{Init}->get_panel_ref,
1827 'None ', 'None', 'Default', 'Default', 'Simple', 'Simple');
1829 -Corrected problem where an incorrect html filename was generated for
1830 external calls to Tidy.pm module. Fixed incorrect html title when
1831 Tidy.pm is called with IO::Scalar or IO::Array source.
1833 -Output file permissons are now set as follows. An output script file
1834 gets the same permission as the input file, except that owner
1835 read/write permission is added (otherwise, perltidy could not be
1836 rerun). Html output files use system defaults. Previously chmod 0755
1837 was used in all cases. Thanks to Mark Olesen for bringing this up.
1839 -Missing semicolons will not be added in multi-line blocks of type
1840 sort, map, or grep. This brings perltidy into closer agreement
1841 with common practice. Of course, you can still put semicolons
1842 there if you like. Thanks to Simon Perreault for a discussion of this.
1844 -Most instances of extra semicolons are now deleted. This is
1845 particularly important if the -csc option is used. Thanks to Wolfgang
1846 Weisselberg for noting this. For example, the following line
1847 (produced by 'h2xs' :) has an extra semicolon which will now be
1850 BEGIN { plan tests => 1 };
1852 -New parameter -csce (--closing-side-comment-else-flag) can be used
1853 to control what text is appended to 'else' and 'elsif' blocks.
1854 Default is to just add leading 'if' text to an 'else'. See manual.
1856 -The -csc option now labels 'else' blocks with additinal information
1857 from the opening if statement and elsif statements, if space.
1858 Thanks to Wolfgang Weisselberg for suggesting this.
1860 -The -csc option will now remove any old closing side comments
1861 below the line interval threshold. Thanks to Wolfgang Weisselberg for
1864 -The abbreviation feature, which was broken in the previous version,
1865 is now fixed. Thanks to Michael Cartmell for noting this.
1867 -Vertical alignment is now done for '||=' .. somehow this was
1871 -This version uses modules for the first time, and a standard perl
1872 Makefile.PL has been supplied. However, perltidy may still be
1873 installed as a single script, without modules. See INSTALL for
1876 -The man page 'perl2web' has been merged back into the main 'perltidy'
1877 man page to simplify installation. So you may remove that man page
1878 if you have an older installation.
1880 -Added patch from Axel Rose for MacPerl. The patch prompts the user
1881 for command line arguments before calling the module
1882 Perl::Tidy::perltidy.
1884 -Corrected bug with '-bar' which was introduced in the previous
1885 version. A closing block brace was being indented. Thanks to
1886 Alexandros M Manoussakis for reporting this.
1888 -New parameter '--entab-leading-whitespace=n', or '-et=n', has been
1889 added for those who prefer tabs. This behaves different from the
1890 existing '-t' parameter; see updated man page. Suggested by Mark
1893 -New parameter '--perl-syntax-check-flags=s' or '-pcsf=s' can be
1894 used to change the flags passed to perltidy in a syntax check.
1895 See updated man page. Suggested by Mark Olesen.
1897 -New parameter '--output-path=s' or '-opath=s' will cause output
1898 files to be placed in directory s. See updated man page. Thanks for
1899 Mark Olesen for suggesting this.
1901 -New parameter --dump-profile (or -dpro) will dump to
1902 standard output information about the search for a
1903 configuration file, the name of whatever configuration file
1904 is selected, and its contents. This should help debugging
1905 config files, especially on different Windows systems.
1907 -The -w parameter now notes possible errors of the form:
1909 $comment = s/^\s*(\S+)\..*/$1/; # trim whitespace
1911 -Corrections added for a leading ':' and for leaving a leading 'tcsh'
1912 line untouched. Mark Olesen reported that lines of this form were
1913 accepted by perl but not by perltidy:
1915 : # use -*- perl -*-
1916 eval 'exec perl -wS $0 "$@"' # shell should exec 'perl'
1917 unless 1; # but Perl should skip this one
1919 Perl will silently swallow a leading colon on line 1 of a
1920 script, and now perltidy will do likewise. For example,
1921 this is a valid script, provided that it is the first line,
1924 : print "Hello World\n";
1926 Also, perltidy will now mark a first line with leading ':' followed by
1927 '#' as type SYSTEM (just as a #! line), not to be formatted.
1929 -List formatting improved for certain lists with special
1930 initial terms, such as occur with 'printf', 'sprintf',
1931 'push', 'pack', 'join', 'chmod'. The special initial term is
1932 now placed on a line by itself. For example, perltidy -gnu
1936 "C4", hex($SourceAddr[0]),
1937 hex($SourceAddr[1]), hex($SourceAddr[2]),
1943 hex($SourceAddr[0]), hex($SourceAddr[1]),
1944 hex($SourceAddr[2]), hex($SourceAddr[3]));
1948 @{$$self{states}}, '64', '66', '68',
1949 '70', '72', '74', '76',
1950 '78', '80', '82', '84',
1951 '86', '88', '90', '92',
1952 '94', '96', '98', '100',
1959 '64', '66', '68', '70', '72', '74', '76',
1960 '78', '80', '82', '84', '86', '88', '90',
1961 '92', '94', '96', '98', '100', '102', '104'
1964 -Lists of complex items, such as matricies, are now detected
1965 and displayed with just one item per row:
1968 $this->{'CURRENT'}{'gfx'}{'MatrixSkew'} = Text::PDF::API::Matrix->new(
1969 [ 1, tan( deg2rad($a) ), 0 ], [ tan( deg2rad($b) ), 1, 0 ],
1974 $this->{'CURRENT'}{'gfx'}{'MatrixSkew'} = Text::PDF::API::Matrix->new(
1975 [ 1, tan( deg2rad($a) ), 0 ],
1976 [ tan( deg2rad($b) ), 1, 0 ],
1980 -The perl syntax check will be turned off for now when input is from
1981 standard input or standard output. The reason is that this requires
1982 temporary files, which has produced far too many problems during
1983 Windows testing. For example, the POSIX module under Windows XP/2000
1984 creates temporary names in the root directory, to which only the
1985 administrator should have permission to write.
1987 -Merged patch sent by Yves Orton to handle appropriate
1988 configuration file locations for different Windows varieties
1989 (2000, NT, Me, XP, 95, 98).
1991 -Added patch to properly handle a for/foreach loop without
1992 parens around a list represented as a qw. I didn't know this
1993 was possible until Wolfgang Weisselberg pointed it out:
1995 foreach my $key qw\Uno Due Tres Quadro\ {
1999 But Perl will give a syntax error without the $ variable; ie this will
2002 foreach qw\Uno Due Tres Quadro\ {
2006 -Merged Windows version detection code sent by Yves Orton. Perltidy
2007 now automatically turns off syntax checking for Win 9x/ME versions,
2008 and this has solved a lot of robustness problems. These systems
2009 cannot reliably handle backtick operators. See man page for
2012 -Merged VMS filename handling patch sent by Michael Cartmell. (Invalid
2013 output filenames were being created in some cases).
2015 -Numerous minor improvements have been made for -lp style indentation.
2017 -Long C-style 'for' expressions will be broken after each ';'.
2019 'perltidy -gnu' gives:
2022 for ($status = $db->seq($key, $value, R_CURSOR()) ; $status == 0
2023 and $key eq $origkey ; $status = $db->seq($key, $value, R_NEXT()))
2026 for ($status = $db->seq($key, $value, R_CURSOR()) ;
2027 $status == 0 and $key eq $origkey ;
2028 $status = $db->seq($key, $value, R_NEXT()))
2030 -For the -lp option, a single long term within parens
2031 (without commas) now has better alignment. For example,
2035 $self->throw("Must specify a known host, not $location,"
2036 . " possible values ("
2037 . join (",", sort keys %hosts) . ")");
2040 $self->throw("Must specify a known host, not $location,"
2041 . " possible values ("
2042 . join (",", sort keys %hosts) . ")");
2045 -This version is about 20 percent faster than the previous
2046 version as a result of optimization work. The largest gain
2047 came from switching to a dispatch hash table in the
2050 -perltidy -html will check to see if HTML::Entities is
2051 installed, and if so, it will use it to encode unsafe
2054 -Added flag -oext=ext to change the output file extension to
2055 be different from the default ('tdy' or 'html'). For
2058 perltidy -html -oext=htm filename
2060 will produce filename.htm
2062 -Added flag -cscw to issue warnings if a closing side comment would replace
2063 an existing, different side comments. See the man page for details.
2064 Thanks to Peter Masiar for helpful discussions.
2066 -Corrected tokenization error of signed hex/octal/binary numbers. For
2067 example, the first hex number below would have been parsed correctly
2068 but the second one was not:
2069 if ( ( $tmp >= 0x80_00_00 ) || ( $tmp < -0x80_00_00 ) ) { }
2071 -'**=' was incorrectly tokenized as '**' and '='. This only
2072 caused a problem with the -extrude opton.
2074 -Corrected a divide by zero when -extrude option is used
2076 -The flag -w will now contain all errors reported by 'perl -c' on the
2077 input file, but otherwise they are not reported. The reason is that
2078 perl will report lots of problems and syntax errors which are not of
2079 interest when only a small snippet is being formatted (such as missing
2080 modules and unknown bare words). Perltidy will always report all
2081 significant syntax errors that it finds, such as unbalanced braces,
2082 unless the -q (quiet) flag is set.
2084 -Merged modifications created by Hugh Myers into perltidy.
2085 These include a 'streamhandle' routine which allows perltidy
2086 as a module to operate on input and output arrays and strings
2087 in addition to files. Documentation and new packaging as a
2088 module should be ready early next year; This is an elegant,
2089 powerful update; many thanks to Hugh for contributing it.
2092 -added a tentative patch which tries to keep any existing breakpoints
2093 at lines with leading keywords map,sort,eval,grep. The idea is to
2094 improve formatting of sequences of list operations, as in a schwartzian
2098 my @sorted = map { $_->[0] }
2099 sort { $a->[1] <=> $b->[1] }
2100 map { [ $_, rand ] } @list;
2104 map { $_->[0] } sort { $a->[1] <=> $b->[1] } map { [ $_, rand ] } @list;
2107 my @sorted = map { $_->[0] }
2108 sort { $a->[1] <=> $b->[1] }
2109 map { [ $_, rand ] } @list;
2111 The new alignment is not as nice as the input, but this is an improvement.
2112 Thanks to Yves Orton for this suggestion.
2114 -modified indentation logic so that a line with leading opening paren,
2115 brace, or square bracket will never have less indentation than the
2116 line with the corresponding opening token. Here's a simple example:
2120 -text => "New Document",
2121 -command => \&new_document
2127 Note how the closing ');' is lined up with the first line, even
2128 though it closes a paren in the 'pack' line. That seems wrong.
2132 -text => "New Document",
2133 -command => \&new_document
2139 This seems nicer: you can up-arrow with an editor and arrive at the
2140 opening 'pack' line.
2142 -corrected minor glitch in which cuddled else (-ce) did not get applied
2143 to an 'unless' block, which should look like this:
2151 Thanks to Jeremy Mates for reporting this.
2153 -The man page has been reorganized to parameters easier to find.
2155 -Added check for multiple definitions of same subroutine. It is easy
2156 to introduce this problem when cutting and pasting. Perl does not
2157 complain about it, but it can lead to disaster.
2159 -The command -pro=filename or -profile=filename may be used to specify a
2160 configuration file which will override the default name of .perltidyrc.
2161 There must not be a space on either side of the '=' sign. I needed
2162 this to be able to easily test perltidy with a variety of different
2163 configuration files.
2165 -Side comment alignment has been improved somewhat across frequent level
2166 changes, as in short if/else blocks. Thanks to Wolfgang Weisselberg
2167 for pointing out this problem. For example:
2170 if ( ref $self ) { # Called as a method
2173 else { # Regular procedure call
2179 if ( ref $self ) { # Called as a method
2182 else { # Regular procedure call
2187 -New command -ssc (--static-side-comment) and related command allows
2188 side comments to be spaced close to preceding character. This is
2189 useful for displaying commented code as side comments.
2191 -New command -csc (--closing-side-comment) and several related
2192 commands allow comments to be added to (and deleted from) any or all
2193 closing block braces. This can be useful if you have to maintain large
2194 programs, especially those that you didn't write. See updated man page.
2195 Thanks to Peter Masiar for this suggestion. For a simple example:
2200 if ( !defined( $_[0] ) ) {
2201 print("Hello, World\n");
2204 print( $_[0], "\n" );
2208 This added '## end sub foo' to the closing brace.
2209 To remove it, perltidy -ncsc.
2211 -New commands -ola, for outdenting labels, and -okw, for outdenting
2212 selected control keywords, were implemented. See the perltidy man
2213 page for details. Thanks to Peter Masiar for this suggestion.
2215 -Hanging side comment change: a comment will not be considered to be a
2216 hanging side comment if there is no leading whitespace on the line.
2217 This should improve the reliability of identifying hanging side comments.
2218 Thanks to Peter Masiar for this suggestion.
2220 -Two new commands for outdenting, -olq (outdent-long-quotes) and -olc
2221 (outdent-long-comments), have been added. The original -oll
2222 (outdent-long-lines) remains, and now is an abbreviation for -olq and -olc.
2223 The new default is just -olq. This was necessary to avoid inconsistency with
2224 the new static block comment option.
2226 -Static block comments: to provide a way to display commented code
2227 better, the convention is used that comments with a leading '##' should
2228 not be formatted as usual. Please see '-sbc' (or '--static-block-comment')
2229 for documentation. It can be deactivated with with -nsbc, but
2230 should not normally be necessary. Thanks to Peter Masiar for this
2233 -Two changes were made to help show structure of complex lists:
2234 (1) breakpoints are forced after every ',' in a list where any of
2235 the list items spans multiple lines, and
2236 (2) List items which span multiple lines now get continuation indentation.
2238 The following example illustrates both of these points. Many thanks to
2239 Wolfgang Weisselberg for this snippet and a discussion of it; this is a
2240 significant formatting improvement. Note how it is easier to see the call
2241 parameters in the NEW version:
2244 assert( __LINE__, ( not defined $check )
2247 or $check eq "old", "Error in parameters",
2248 defined $old_new ? ( ref $old_new ? ref $old_new : $old_new ) : "undef",
2249 defined $db_new ? ( ref $db_new ? ref $db_new : $db_new ) : "undef",
2250 defined $old_db ? ( ref $old_db ? ref $old_db : $old_db ) : "undef" );
2255 ( not defined $check )
2259 "Error in parameters",
2260 defined $old_new ? ( ref $old_new ? ref $old_new : $old_new ) : "undef",
2261 defined $db_new ? ( ref $db_new ? ref $db_new : $db_new ) : "undef",
2262 defined $old_db ? ( ref $old_db ? ref $old_db : $old_db ) : "undef"
2265 Another example shows how this helps displaying lists:
2268 %{ $self->{COMPONENTS} } = (
2270 { type => 'name', adj => 'yes', font => 'Helvetica', 'index' => 0 },
2272 { type => 'road', adj => 'yes', font => 'Helvetica', 'index' => 2 },
2275 The structure is clearer with the added indentation:
2278 %{ $self->{COMPONENTS} } = (
2280 { type => 'name', adj => 'yes', font => 'Helvetica', 'index' => 0 },
2282 { type => 'road', adj => 'yes', font => 'Helvetica', 'index' => 2 },
2285 -The structure of nested logical expressions is now displayed better.
2286 Thanks to Wolfgang Weisselberg for helpful discussions. For example,
2287 note how the status of the final 'or' is displayed in the following:
2291 and null( $op->sibling )
2292 and $op->ppaddr eq "pp_null"
2293 and class($op) eq "UNOP"
2294 and ( ( $op->first->ppaddr =~ /^pp_(and|or)$/
2295 and $op->first->first->sibling->ppaddr eq "pp_lineseq" )
2296 or ( $op->first->ppaddr eq "pp_lineseq"
2297 and not null $op->first->first->sibling
2298 and $op->first->first->sibling->ppaddr eq "pp_unstack" ) ) );
2303 and null( $op->sibling )
2304 and $op->ppaddr eq "pp_null"
2305 and class($op) eq "UNOP"
2308 $op->first->ppaddr =~ /^pp_(and|or)$/
2309 and $op->first->first->sibling->ppaddr eq "pp_lineseq"
2311 or ( $op->first->ppaddr eq "pp_lineseq"
2312 and not null $op->first->first->sibling
2313 and $op->first->first->sibling->ppaddr eq "pp_unstack" )
2317 -A break will always be put before a list item containing a comma-arrow.
2318 This will improve formatting of mixed lists of this form:
2322 'text', 225, 20, -text => 'A Simple Plot',
2330 -text => 'A Simple Plot',
2335 -For convenience, the command -dac (--delete-all-comments) now also
2336 deletes pod. Likewise, -tac (--tee-all-comments) now also sends pod
2337 to a '.TEE' file. Complete control over the treatment of pod and
2338 comments is still possible, as described in the updated help message
2341 -The logic which breaks open 'containers' has been rewritten to be completely
2342 symmetric in the following sense: if a line break is placed after an opening
2343 {, [, or (, then a break will be placed before the corresponding closing
2344 token. Thus, a container either remains closed or is completely cracked
2347 -Improved indentation of parenthesized lists. For example,
2352 atan2( $GPSTempCompLong - $GPSLongitude,
2353 $GPSLatitude - $GPSTempCompLat ) * 180 / 3.14159265 );
2356 $GPSCompCourse = int(
2358 $GPSTempCompLong - $GPSLongitude,
2359 $GPSLatitude - $GPSTempCompLat
2360 ) * 180 / 3.14159265
2363 Further improvements will be made in future releases.
2365 -Some improvements were made in formatting small lists.
2367 -Correspondence between Input and Output line numbers reported in a
2368 .LOG file should now be exact. They were sometimes off due to the size
2369 of intermediate buffers.
2371 -Corrected minor tokenization error in which a ';' in a foreach loop
2372 control was tokenized as a statement termination, which forced a
2385 foreach ( $i = 0 ; $i <= 10 ; $i += 2 ) {
2389 -Corrected a problem with reading config files, in which quote marks were not
2390 stripped. As a result, something like -wba="&& . || " would have the leading
2391 quote attached to the && and not work correctly. A workaround for older
2392 versions is to place a space around all tokens within the quotes, like this:
2395 -Removed any existing space between a label and its ':'
2398 This was necessary because the label and its colon are a single token.
2400 -Corrected tokenization error for the following (highly non-recommended)
2402 $user = @vars[1] / 100;
2404 -Resolved cause of a difference between perltidy under perl v5.6.1 and
2405 5.005_03; the problem was different behavior of \G regex position
2409 -Corrected a bug in which a break was not being made after a full-line
2410 comment within a short eval/sort/map/grep block. A flag was not being
2411 zeroed. The syntax error check catches this. Here is a snippet which
2412 illustrates the bug:
2415 #open Socket to Dispatcher
2416 $sock = &OpenSocket;
2419 The formatter mistakenly thought that it had found the following
2422 eval {#open Socket to Dispatcher$sock = &OpenSocket; };
2424 The patch fixes this. Many thanks to Henry Story for reporting this bug.
2426 -Changes were made to help diagnose and resolve problems in a
2428 (1) processing of command parameters has been into two separate
2429 batches so that any errors in a .perltidyrc file can be localized.
2430 (2) commands --help, --version, and as many of the --dump-xxx
2431 commands are handled immediately, without any command line processing
2433 (3) Perltidy will ignore any commands in the .perltidyrc file which
2434 cause immediate exit. These are: -h -v -ddf -dln -dop -dsn -dtt
2435 -dwls -dwrs -ss. Thanks to Wolfgang Weisselberg for helpful
2436 suggestions regarding these updates.
2438 -Syntax check has been reinstated as default for MSWin32 systems. This
2439 way Windows 2000 users will get syntax check by default, which seems
2440 like a better idea, since the number of Win 95/98 systems will be
2441 decreasing over time. Documentation revised to warn Windows 95/98
2442 users about the problem with empty '&1'. Too bad these systems
2443 all report themselves as MSWin32.
2446 -Fixed tokenization error in which a method call of the form
2450 got a space before the '::' like this:
2454 Thanks to David Holden for reporting this.
2456 -Added -html control over pod text, using a new abbreviation 'pd'. See
2457 updated perl2web man page. The default is to use the color of a comment,
2458 but italicized. Old .css style sheets will need a new line for
2459 .pd to use this. The old color was the color of a string, and there
2462 -.css lines are now printed in sorted order.
2464 -Fixed interpolation problem where html files had '$input_file' as title
2465 instead of actual input file name. Thanks to Simon Perreault for finding
2466 this and sending a patch, and also to Tobias Weber.
2468 -Breaks will now have the ':' placed at the start of a line,
2469 one per line by default because this shows logical structure
2470 more clearly. This coding has been completely redone. Some
2471 examples of new ?/: formatting:
2474 wantarray ? map( $dir::cwd->lookup($_)->path, @_ ) :
2475 $dir::cwd->lookup( $_[0] )->path;
2479 ? map( $dir::cwd->lookup($_)->path, @_ )
2480 : $dir::cwd->lookup( $_[0] )->path;
2486 } : { a => 6, b => 8 };
2494 : { a => 6, b => 8 };
2497 $self->note($self->{skip} ? "Hunk #$self->{hunk} ignored at 1.\n" :
2498 "Hunk #$self->{hunk} failed--$@");
2501 $self->note($self->{skip}
2502 ? "Hunk #$self->{hunk} ignored at 1.\n"
2503 : "Hunk #$self->{hunk} failed--$@");
2507 $opts{"t"} ? 'title' :
2508 $opts{"s"} ? 'subject' : $opts{"a"} ? 'author' : 'title';
2512 $opts{"t"} ? 'title'
2513 : $opts{"s"} ? 'subject'
2514 : $opts{"a"} ? 'author'
2517 You can use -wba=':' to recover the previous default which placed ':'
2518 at the end of a line. Thanks to Michael Cartmell for helpful
2519 discussions and examples.
2521 -Tokenizer updated to do syntax checking for matched ?/: pairs. Also,
2522 the tokenizer now outputs a unique serial number for every balanced
2523 pair of brace types and ?/: pairs. This greatly simplifies the
2526 -Long lines with repeated 'and', 'or', '&&', '||' will now have
2527 one such item per line. For example:
2530 if ( $opt_d || $opt_m || $opt_p || $opt_t || $opt_x
2531 || ( -e $archive && $opt_r ) )
2533 ( $pAr, $pNames ) = readAr($archive);
2542 || ( -e $archive && $opt_r ) )
2544 ( $pAr, $pNames ) = readAr($archive);
2548 if ( $vp->{X0} + 4 <= $x && $vp->{X0} + $vp->{W} - 4 >= $x
2549 && $vp->{Y0} + 4 <= $y && $vp->{Y0} + $vp->{H} - 4 >= $y )
2552 if ( $vp->{X0} + 4 <= $x
2553 && $vp->{X0} + $vp->{W} - 4 >= $x
2554 && $vp->{Y0} + 4 <= $y
2555 && $vp->{Y0} + $vp->{H} - 4 >= $y )
2557 -Long lines with multiple concatenated tokens will have concatenated
2558 terms (see below) placed one per line, except for short items. For
2563 "Device type:" . $ib->family . " ID:" . $ib->serial . " CRC:"
2564 . $ib->crc . ": " . $ib->model() . "\n";
2567 $report .= "Device type:"
2568 . $ib->family . " ID:"
2569 . $ib->serial . " CRC:"
2571 . $ib->crc . ": " . "\n";
2573 NOTE: at present 'short' means 8 characters or less. There is a
2574 tentative flag to change this (-scl), but it is undocumented and
2575 is likely to be changed or removed later, so only use it for testing.
2576 In the above example, the tokens " ID:", " CRC:", and "\n" are below
2579 -If a line which is short enough to fit on a single line was
2580 nevertheless broken in the input file at a 'good' location (see below),
2581 perltidy will try to retain a break. For example, the following line
2582 will be formatted as:
2585 or die "Cannot open $file ($!)";
2587 if it was broken in the input file, and like this if not:
2589 open SUM, "<$file" or die "Cannot open $file ($!)";
2591 GOOD: 'good' location means before 'and','or','if','unless','&&','||'
2593 The reason perltidy does not just always break at these points is that if
2594 there are multiple, similar statements, this would preclude alignment. So
2595 rather than check for this, perltidy just tries to follow the input style,
2596 in the hopes that the author made a good choice. Here is an example where
2597 we might not want to break before each 'if':
2599 ($Locale, @Locale) = ($English, @English) if (@English > @Locale);
2600 ($Locale, @Locale) = ($German, @German) if (@German > @Locale);
2601 ($Locale, @Locale) = ($French, @French) if (@French > @Locale);
2602 ($Locale, @Locale) = ($Spanish, @Spanish) if (@Spanish > @Locale);
2604 -Added wildcard file expansion for systems with shells which lack this.
2605 Now 'perltidy *.pl' should work under MSDOS/Windows. Thanks to Hugh Myers
2606 for suggesting this. This uses builtin glob() for now; I may change that.
2608 -Added new flag -sbl which, if specified, overrides the value of -bl
2609 for opening sub braces. This allows formatting of this type:
2615 if (!defined($_[0])) {
2616 print("Hello, World\n");
2622 Requested by Don Alexander.
2624 -Fixed minor parsing error which prevented a space after a $$ variable
2625 (pid) in some cases. Thanks to Michael Cartmell for noting this.
2630 -Improved line break choices 'and' and 'or' to display logic better.
2634 exists $self->{'build_dir'} and push @e,
2635 "Unwrapped into directory $self->{'build_dir'}";
2638 exists $self->{'build_dir'}
2639 and push @e, "Unwrapped into directory $self->{'build_dir'}";
2641 -Fixed error of multiple use of abbreviatioin '-dsc'. -dsc remains
2642 abbreviation for delete-side-comments; -dsm is new abbreviation for
2645 -Corrected and updated 'usage' help routine. Thanks to Slaven Rezic for
2648 -The default for Windows is, for now, not to do a 'perl -c' syntax
2649 check (but -syn will activate it). This is because of problems with
2650 command.com. James Freeman sent me a patch which tries to get around
2651 the problems, and it works in many cases, but testing revealed several
2652 issues that still need to be resolved. So for now, the default is no
2653 syntax check for Windows.
2655 -I added a -T flag when doing perl -c syntax check.
2656 This is because I test it on a large number of scripts from sources
2657 unknown, and who knows what might be hidden in initialization blocks?
2658 Also, deactivated the syntax check if perltidy is run as root. As a
2659 benign example, running the previous version of perltidy on the
2660 following file would cause it to disappear:
2663 print "Bye, bye baby!\n";
2667 The new version will not let that happen.
2669 -I am contemplating (but have not yet implemented) making '-lp' the
2670 default indentation, because it is stable now and may be closer to how
2671 perl is commonly formatted. This could be in the next release. The
2672 reason that '-lp' was not the original default is that the coding for
2673 it was complex and not ready for the initial release of perltidy. If
2674 anyone has any strong feelings about this, I'd like to hear. The
2675 current default could always be recovered with the '-nlp' flag.
2679 - sub definition names are now specially colored, red by default.
2680 The letter 'm' is used to identify them.
2681 - keyword 'sub' now has color of other keywords.
2682 - restored html keyword color to __END__ and __DATA__, which was
2683 accidentally removed in the previous version.
2685 -A new -se (--standard-error-output) flag has been implemented and
2686 documented which causes all errors to be written to standard output
2687 instead of a .ERR file.
2689 -A new -w (--warning-output) flag has been implemented and documented
2690 which causes perltidy to output certain non-critical messages to the
2691 error output file, .ERR. These include complaints about pod usage,
2692 for example. The default is to not include these.
2694 NOTE: This replaces an undocumented -w=0 or --warning-level flag
2695 which was tentatively introduced in the previous version to avoid some
2696 unwanted messages. The new default is the same as the old -w=0, so
2697 that is no longer needed.
2699 -Improved syntax checking and corrected tokenization of functions such
2700 as rand, srand, sqrt, ... These can accept either an operator or a term
2701 to their right. This has been corrected.
2703 -Corrected tokenization of semicolon: testing of the previous update showed
2704 that the semicolon in the following statement was being mis-tokenized. That
2705 did no harm, other than adding an extra blank space, but has been corrected.
2707 for (sort {strcoll($a,$b);} keys %investments) {
2711 -New syntax check: after wasting 5 minutes trying to resolve a syntax
2712 error in which I had an extra terminal ';' in a complex for (;;) statement,
2713 I spent a few more minutes adding a check for this in perltidy so it won't
2716 -The behavior of --break-before-subs (-bbs) and --break-before-blocks
2717 (-bbb) has been modified. Also, a new control parameter,
2718 --long-block-line-count=n (-lbl=n) has been introduced to give more
2719 control on -bbb. This was previously a hardwired value. The reason
2720 for the change is to reduce the number of unwanted blank lines that
2721 perltidy introduces, and make it less erratic. It's annoying to remove
2722 an unwanted blank line and have perltidy put it back. The goal is to
2723 be able to sprinkle a few blank lines in that dense script you
2724 inherited from Bubba. I did a lot of experimenting with different
2725 schemes for introducing blank lines before and after code blocks, and
2726 decided that there is no really good way to do it. But I think the new
2727 scheme is an improvement. You can always deactivate this with -nbbb.
2728 I've been meaning to work on this; thanks to Erik Thaysen for bringing
2731 -The .LOG file is seldom needed, and I get tired of deleting them, so
2732 they will now only be automatically saved if perltidy thinks that it
2733 made an error, which is almost never. You can still force the logfile
2734 to be saved with -log or -g.
2736 -Improved method for computing number of columns in a table. The old
2737 method always tried for an even number. The new method allows odd
2738 numbers when it is obvious that a list is not a hash initialization
2742 $name, $xsargs, $parobjs, $optypes,
2743 $hasp2child, $pmcode, $hdrcode, $inplacecode,
2744 $globalnew, $callcopy
2749 $name, $xsargs, $parobjs, $optypes, $hasp2child,
2750 $pmcode, $hdrcode, $inplacecode, $globalnew, $callcopy
2754 -I fiddled with the list threshold adjustment, and some small lists
2755 look better now. Here is the change for one of the lists in test file
2759 ("in", "in", "pt", "pt", "pc", "pi", "mm", "mm", "cm", "cm", "\\hsize", "%",
2760 "\\vsize", "%", "\\textwidth", "%", "\\textheight", "%");
2764 "in", "in", "pt", "pt", "pc", "pi",
2765 "mm", "mm", "cm", "cm", "\\hsize", "%",
2766 "\\vsize", "%", "\\textwidth", "%", "\\textheight", "%"
2769 -Improved -lp formatting at '=' sign. A break was always being added after
2770 the '=' sign in a statement such as this, (to be sure there was enough room
2771 for the parameters):
2776 $biblionumber, $constraint,
2780 The updated version doesn't do this unless the space is really needed:
2782 new: my $fee = CalcReserveFee(
2784 $biblionumber, $constraint,
2788 -I updated the tokenizer to allow $#+ and $#-, which seem to be new to
2789 Perl 5.6. Some experimenting with a recent version of Perl indicated
2790 that it allows these non-alphanumeric '$#' array maximum index
2791 varaibles: $#: $#- $#+ so I updated the parser accordingly. Only $#:
2792 seems to be valid in older versions of Perl.
2794 -Fixed a rare formatting problem with -lp (and -gnu) which caused
2795 excessive indentation.
2797 -Many additional syntax checks have been added.
2799 -Revised method for testing here-doc target strings; the following
2800 was causing trouble with a regex test because of the '*' characters:
2804 Perl seems to allow almost anything to be a here doc target, so an
2805 exact string comparison is now used.
2807 -Made update to allow underscores in binary numbers, like '0b1100_0000'.
2809 -Corrected problem with scanning certain module names; a blank space was
2810 being inserted after 'warnings' in the following:
2811 use warnings::register;
2812 The problem was that warnings (and a couple of other key modules) were
2813 being tokenized as keywords. They should have just been identifiers.
2815 -Corrected tokenization of indirect objects after sort, system, and exec,
2816 after testing produced an incorrect error message for the following
2818 print sort $sortsubref @list;
2820 -Corrected minor problem where a line after a format had unwanted
2821 extra continuation indentation.
2823 -Delete-block-comments (and -dac) now retain any leading hash-bang line
2825 -Update for -lp (and -gnu) to not align the leading '=' of a list
2826 with a previous '=', since this interferes with alignment of parameters.
2828 old: my $hireDay = new Date;
2835 new: my $hireDay = new Date;
2842 -Modifications made to display tables more compactly when possible,
2843 without adding lines. For example,
2845 '1', "I", '2', "II", '3', "III", '4', "IV",
2846 '5', "V", '6', "VI", '7', "VII", '8', "VIII",
2849 '1', "I", '2', "II", '3', "III",
2850 '4', "IV", '5', "V", '6', "VI",
2851 '7', "VII", '8', "VIII", '9', "IX"
2853 -Corrected minor bug in which -pt=2 did not keep the right paren tight
2854 around a '++' or '--' token, like this:
2856 for ($i = 0 ; $i < length $key ; $i++ )
2858 The formatting for this should be, and now is:
2860 for ($i = 0 ; $i < length $key ; $i++)
2862 Thanks to Erik Thaysen for noting this.
2864 -Discovered a new bug involving here-docs during testing! See BUGS.html.
2866 -Finally fixed parsing of subroutine attributes (A Perl 5.6 feature).
2867 However, the attributes and prototypes must still be on the same line
2871 -Corrected minor, uncommon bug found during routine testing, in which a
2872 blank got inserted between a function name and its opening paren after
2873 a file test operator, but only in the case that the function had not
2874 been previously seen. Perl uses the existence (or lack thereof) of
2875 the blank to guess if it is a function call. That is,
2876 if (-l pid_filename()) {
2878 if (-l pid_filename ()) {
2879 which is a syntax error if pid_filename has not been seen by perl.
2881 -If the AutoLoader module is used, perltidy will continue formatting
2882 code after seeing an __END__ line. Use -nlal to deactivate this feature.
2883 Likewise, if the SelfLoader module is used, perltidy will continue
2884 formatting code after seeing a __DATA__ line. Use -nlsl to
2885 deactivate this feature. Thanks to Slaven Rezic for this suggestion.
2887 -pod text after __END__ and __DATA__ is now identified by perltidy
2888 so that -dp works correctly. Thanks to Slaven Rezic for this suggestion.
2890 -The first $VERSION line which might be eval'd by MakeMaker
2891 is now passed through unchanged. Use -npvl to deactivate this feature.
2892 Thanks to Manfred Winter for this suggestion.
2894 -Improved indentation of nested parenthesized expressions. Tests have
2895 given favorable results. Thanks to Wolfgang Weisselberg for helpful
2899 -Fixed a very rare problem in which an unwanted semicolon was inserted
2900 due to misidentification of anonymous hash reference curly as a code
2901 block curly. (No instances of this have been reported; I discovered it
2902 during testing). A workaround for older versions of perltidy is to use
2905 -Added -icb (-indent-closing-brace) parameter to indent a brace which
2906 terminates a code block to the same level as the previous line.
2907 Suggested by Andrew Cutler. For example,
2916 -Rewrote error message triggered by an unknown bareword in a print or
2917 printf filehandle position, and added flag -w=0 to prevent issuing this
2918 error message. Suggested by Byron Jones.
2920 -Added modification to align a one-line 'if' block with similar
2921 following 'elsif' one-line blocks, like this:
2922 if ( $something eq "simple" ) { &handle_simple }
2923 elsif ( $something eq "hard" ) { &handle_hard }
2924 (Suggested by Wolfgang Weisselberg).
2927 -Eliminated all constants with leading underscores because perl 5.005_03
2928 does not support that. For example, _SPACES changed to XX_SPACES.
2929 Thanks to kromJx for this update.
2932 -the directory of test files has been moved to a separate distribution
2933 file because it is getting large but is of little interest to most users.
2934 For the current distribution:
2935 perltidy-20010701.tgz contains the source and docs for perltidy
2936 perltidy-20010701-test.tgz contains the test files
2938 -fixed bug where temporary file perltidy.TMPI was not being deleted
2939 when input was from stdin.
2941 -adjusted line break logic to not break after closing brace of an
2942 eval block (suggested by Boris Zentner).
2944 -added flag -gnu (--gnu-style) to give an approximation to the GNU
2945 style as sometimes applied to perl. The programming style in GNU
2946 'automake' was used as a guide in setting the parameters; these
2947 parameters will probably be adjusted over time.
2949 -an empty code block now has one space for emphasis:
2950 if ( $cmd eq "bg_untested" ) {} # old
2951 if ( $cmd eq "bg_untested" ) { } # new
2952 If this bothers anyone, we could create a parameter.
2954 -the -bt (--brace-tightness) parameter has been split into two
2955 parameters to give more control. -bt now applies only to non-BLOCK
2956 braces, while a new parameter -bbt (block-brace-tightness) applies to
2957 curly braces which contain code BLOCKS. The default value is -bbt=0.
2959 -added flag -icp (--indent-closing-paren) which leaves a statement
2960 termination of the form );, };, or ]; indented with the same
2961 indentation as the previous line. For example,
2963 @month_of_year = ( # default, or -nicp
2964 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct',
2968 @month_of_year = ( # -icp
2969 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct',
2973 -Vertical alignment updated to synchronize with tokens &&, ||,
2974 and, or, if, unless. Allowable space before forcing
2975 resynchronization has been increased. (Suggested by Wolfgang
2978 -html corrected to use -nohtml-bold-xxxxxxx or -nhbx to negate bold,
2979 and likewise -nohtml-italic-xxxxxxx or -nhbi to negate italic. There
2980 was no way to negate these previously. html documentation updated and
2981 corrected. (Suggested by Wolfgang Weisselberg).
2983 -Some modifications have been made which improve the -lp formatting in
2986 -Perltidy now retains or creates a blank line after an =cut to keep
2987 podchecker happy (Suggested by Manfred H. Winter). This appears to be
2988 a glitch in podchecker, but it was annoying.
2991 -Added -bli flag to give continuation indentation to braces, like this
2995 extra_indentation();
2998 -Corrected an error with the tab (-t) option which caused the last line
2999 of a multi-line quote to receive a leading tab. This error was in
3000 version 2001 06 08 but not 2001 04 06. If you formatted a script
3001 with -t with this version, please check it by running once with the
3002 -chk flag and perltidy will scan for this possible error.
3004 -Corrected an invalid pattern (\R should have been just R), changed
3005 $^W =1 to BEGIN {$^W=1} to use warnings in compile phase, and corrected
3006 several unnecessary 'my' declarations. Many thanks to Wolfgang Weisselberg,
3007 2001-06-12, for catching these errors.
3009 -A '-bar' flag has been added to require braces to always be on the
3010 right, even for multi-line if and foreach statements. For example,
3011 the default formatting of a long if statement would be:
3013 if ($bigwasteofspace1 && $bigwasteofspace2
3014 || $bigwasteofspace3 && $bigwasteofspace4)
3019 With -bar, the formatting is:
3021 if ($bigwasteofspace1 && $bigwasteofspace2
3022 || $bigwasteofspace3 && $bigwasteofspace4) {
3025 Suggested by Eli Fidler 2001-06-11.
3027 -Uploaded perltidy to sourceforge cvs 2001-06-10.
3029 -An '-lp' flag (--line-up-parentheses) has been added which causes lists
3030 to be indented with extra indentation in the manner sometimes
3031 associated with emacs or the GNU suggestions. Thanks to Ian Stuart for
3032 this suggestion and for extensive help in testing it.
3034 -Subroutine call parameter lists are now formatted as other lists.
3035 This should improve formatting of tables being passed via subroutine
3036 calls. This will also cause full indentation ('-i=n, default n= 4) of
3037 continued parameter list lines rather than just the number of spaces
3038 given with -ci=n, default n=2.
3040 -Added support for hanging side comments. Perltidy identifies a hanging
3041 side comment as a comment immediately following a line with a side
3042 comment or another hanging side comment. This should work in most
3043 cases. It can be deactivated with --no-hanging-side-comments (-nhsc).
3044 The manual has been updated to discuss this. Suggested by Brad
3045 Eisenberg some time ago, and finally implemented.
3048 -fixed problem with parsing command parameters containing quoted
3049 strings in .perltidyrc files. (Reported by Roger Espel Llima 2001-06-07).
3051 -added two command line flags, --want-break-after and
3052 --want-break-before, which allow changing whether perltidy
3053 breaks lines before or after any operators. Please see the revised
3054 man pages for details.
3056 -added system-wide configuration file capability.
3057 If perltidy does not find a .perltidyrc command line file in
3058 the current directory, nor in the home directory, it now looks
3059 for '/usr/local/etc/perltidyrc' and then for '/etc/perltidyrc'.
3060 (Suggested by Roger Espel Llima 2001-05-31).
3062 -fixed problem in which spaces were trimmed from lines of a multi-line
3063 quote. (Reported by Roger Espel Llima 2001-05-30). This is an
3064 uncommon situation, but serious, because it could conceivably change
3065 the proper function of a script.
3067 -fixed problem in which a semicolon was incorrectly added within
3068 an anonymous hash. (Reported by A.C. Yardley, 2001-5-23).
3069 (You would know if this happened, because perl would give a syntax
3070 error for the resulting script).
3072 -fixed problem in which an incorrect error message was produced
3073 after a version number on a 'use' line, like this ( Reported
3074 by Andres Kroonmaa, 2001-5-14):
3076 use CGI 2.42 qw(fatalsToBrowser);
3078 Other than the extraneous error message, this bug was harmless.
3081 -fixed serious bug in which the last line of some multi-line quotes or
3082 patterns was given continuation indentation spaces. This may make
3083 a pattern incorrect unless it uses the /x modifier. To find
3084 instances of this error in scripts which have been formatted with
3085 earlier versions of perltidy, run with the -chk flag, which has
3086 been added for this purpose (SLH, 2001-04-05).
3088 ** So, please check previously formatted scripts by running with -chk
3091 -continuation indentation has been reprogrammed to be hierarchical,
3092 which improves deeply nested structures.
3094 -fixed problem with undefined value in list formatting (reported by Michael
3097 -Switched to graphical display of nesting in .LOG files. If an
3098 old format string was "(1 [0 {2", the new string is "{{(". This
3099 is easier to read and also shows the order of nesting.
3101 -added outdenting of cuddled paren structures, like ")->pack(".
3103 -added line break and outdenting of ')->' so that instead of
3106 -text => "perltidy",
3107 -relief => 'ridge')->pack;
3109 the current default is:
3112 -text => "perltidy",
3116 (requested by Michael Langner 2001-03-31; in the future this could
3117 be controlled by a command-line parameter).
3119 -revised list indentation logic, so that lists following an assignment
3120 operator get one full indentation level, rather than just continuation
3121 indentation. Also corrected some minor glitches in the continuation
3124 -Fixed problem with unwanted continuation indentation after a blank line
3125 (reported by Erik Thaysen 2001-03-28):
3127 -minor update to avoid stranding a single '(' on one line
3130 -corrected serious error tokenizing filehandles, in which a sub call
3131 after a print or printf, like this:
3132 print usage() and exit;
3134 print usage () and exit;
3135 Unfortunately, this converts 'usage' to a filehandle. To fix this, rerun
3136 perltidy; it will look for this situation and issue a warning.
3138 -fixed another cuddled-else formatting bug (Reported by Craig Bourne)
3140 -added several diagnostic --dump routines
3142 -added token-level whitespace controls (suggested by Hans Ecke)
3145 -added support for special variables of the form ${^WANT_BITS}
3147 -space added between scalar and left paren in 'for' and 'foreach' loops,
3148 (suggestion by Michael Cartmell):
3150 for $i( 1 .. 20 ) # old
3151 for $i ( 1 .. 20 ) # new
3153 -html now outputs cascading style sheets (thanks to suggestion from
3156 -flags -o and -st now work with -html
3158 -added missing -html documentation for comments (noted by Alex Izvorski)
3160 -support for VMS added (thanks to Michael Cartmell for code patches and
3163 -v-strings implemented (noted by Hans Ecke and Michael Cartmell; extensive
3164 testing by Michael Cartmell)
3166 -fixed problem where operand may be empty at line 3970
3167 (\b should be just b in lines 3970, 3973) (Thanks to Erik Thaysen,
3168 Keith Marshall for bug reports)
3170 -fixed -ce bug (cuddled else), where lines like '} else {' were indented
3171 (Thanks to Shawn Stepper and Rick Measham for reporting this)
3174 -fixed undefined value in line 153 (only worked with -I set)
3175 (Thanks to Mike Stok, Phantom of the Opcodes, Ian Ehrenwald, and others)
3177 -fixed undefined value in line 1069 (filehandle problem with perl versions <
3178 5.6) (Thanks to Yuri Leikind, Mike Stok, Michael Holve, Jeff Kolber)
3181 -Initial announcement at freshmeat.net; started Change Log
3182 (Unfortunately this version was DOA, but it was fixed the next day)
