3 - added new flag -it=n or --iterations=n
4 This flag causes perltidy to do n complete iterations.
5 For most purposes the default of n=1 should be satisfactory. However n=2
6 can be useful when a major style change is being made, or when code is being
7 beautified on check-in to a source code control system. The run time will be
8 approximately proportional to n, and it should seldom be necessary to use a
9 value greater than n=2. Thanks to Jonathan Swartz
11 - A configuration file pathname begins with three dots, e.g.
12 ".../.perltidyrc", indicates that the file should be searched for starting
13 in the current directory and working upwards. This makes it easier to have
14 multiple projects each with their own .perltidyrc in their root directories.
15 Thanks to Jonathan Swartz for this patch.
17 - Added flag --notidy which disables all formatting and causes the input to be
18 copied unchanged. This can be useful in conjunction with hierarchical
19 F<.perltidyrc> files to prevent unwanted tidying.
20 Thanks to Jonathan Swartz for this patch.
22 - Added prefilters and postfilters in the call to the Tidy.pm module.
23 Prefilters and postfilters. The prefilter is a code reference that
24 will be applied to the source before tidying, and the postfilter
25 is a code reference to the result before outputting.
27 Thanks to Jonathan Swartz for this patch. He writes:
28 This is useful for all manner of customizations. For example, I use
29 it to convert the 'method' keyword to 'sub' so that perltidy will work for
30 Method::Signature::Simple code:
33 prefilter => sub { $_ = $_[0]; s/^method (.*)/sub $1 \#__METHOD/gm; return $_ },
34 postfilter => sub { $_ = $_[0]; s/^sub (.*?)\s* \#__METHOD/method $1/gm; return $_ }
37 - The starting indentation level of sections of code entabbed with -et=n
38 is correctly guessed if it was also produced with the same -et=n flag. This
39 keeps the indentation stable on repeated formatting passes within an editor.
40 Thanks to Sam Kington and Glenn.
42 - Functions with prototype '&' had a space between the function and opening
43 peren. This space now only occurs if the flag --space-function-paren (-sfp)
44 is set. Thanks to Zrajm Akfohg.
46 - Patch to never put spaces around a bare word in braces beginning with ^ as in:
47 my $before = ${^PREMATCH};
48 even if requested with the -bt=0 flag because any spaces cause a syntax error in perl.
49 Thanks to Fabrice Dulanoy.
52 - Allow configuration file to be 'perltidy.ini' for Windows systems.
53 i.e. C:\Documents and Settings\User\perltidy.ini
54 and added documentation for setting configuation file under Windows in man
55 page. Thanks to Stuart Clark.
57 - Corrected problem of unwanted semicolons in hash ref within given/when code.
58 Thanks to Nelo Onyiah.
60 - added new flag -cscb or --closing-side-comments-balanced
61 When using closing-side-comments, and the closing-side-comment-maximum-text
62 limit is exceeded, then the comment text must be truncated. Previous
63 versions of perltidy terminate with three dots, and this can still be
68 } ## end foreach my $foo (sort { $b cmp $a ...
70 However this causes a problem with older editors which cannot recognize
71 comments or are not configured to doso because they cannot "bounce" around in
72 the text correctly. The B<-cscb> flag tries to help them by
73 appending appropriate terminal balancing structure:
77 } ## end foreach my $foo (sort { $b cmp $a ... })
79 Since there is much to be gained and little to be lost by doing this,
80 the default is B<-cscb>. Use B<-ncscb> if you do not want this.
82 Thanks to Daniel Becker for suggesting this option.
84 - After an isolated closing eval block the continuation indentation will be
85 removed so that the braces line up more like other blocks. Thanks to Yves Orton.
104 -A new flag -asbl (or --opening-anonymous-sub-brace-on-new-line) has
105 been added to put the opening brace of anonymous sub's on a new line,
106 as in the following snippet:
114 This was not possible before because the -sbl flag only applies to named
115 subs. Thanks to Benjamin Krupp.
117 -Fix tokenization bug with the following snippet
118 print 'hi' if { x => 1, }->{x};
119 which resulted in a semicolon being added after the comma. The workaround
120 was to use -nasc, but this is no longer necessary. Thanks to Brian Duggan.
122 -Fixed problem in which an incorrect error message could be triggered
123 by the (unusual) combination of parameters -lp -i=0 -l=2 -ci=0 for
124 example. Thanks to Richard Jelinek.
126 -A new flag --keep-old-blank-lines=n has been added to
127 give more control over the treatment of old blank lines in
128 a script. The manual has been revised to discuss the new
129 flag and clarify the treatment of old blank lines. Thanks
133 -Improved support for perl 5.10: New quote modifier 'p', new block type UNITCHECK,
134 new keyword break, improved formatting of given/when.
136 -Corrected tokenization bug of something like $var{-q}.
138 -Numerous minor formatting improvements.
140 -Corrected list of operators controlled by -baao -bbao to include
141 . : ? && || and or err xor
143 -Corrected very minor error in log file involving incorrect comment
144 regarding need for upper case of labels.
146 -Fixed problem where perltidy could run for a very long time
147 when given certain non-perl text files.
149 -Line breaks in un-parenthesized lists now try to follow
150 line breaks in the input file rather than trying to fill
151 lines. This usually works better, but if this causes
152 trouble you can use -iob to ignore any old line breaks.
153 Example for the following input snippet:
156 "conformability (Not the same dimension)\n",
157 "\t", $have, " is ", text_unit($hu), "\n",
158 "\t", $want, " is ", text_unit($wu), "\n",
162 print "conformability (Not the same dimension)\n", "\t", $have, " is ",
163 text_unit($hu), "\n", "\t", $want, " is ", text_unit($wu), "\n",;
166 print "conformability (Not the same dimension)\n",
167 "\t", $have, " is ", text_unit($hu), "\n",
168 "\t", $want, " is ", text_unit($wu), "\n",
172 -Added -fpsc option (--fixed-position-side-comment). Thanks to Ueli Hugenschmidt.
173 For example -fpsc=40 tells perltidy to put side comments in column 40
176 -Added -bbao and -baao options (--break-before-all-operators and
177 --break-after-all-operators) to simplify command lines and configuration
178 files. These define an initial preference for breaking at operators which can
179 be modified with -wba and -wbb flags. For example to break before all operators
180 except an = one could use --bbao -wba='=' rather than listing every
181 single perl operator (except =) on a -wbb flag.
183 -Added -kis option (--keep-interior-semicolons). Use the B<-kis> flag
184 to prevent breaking at a semicolon if there was no break there in the
185 input file. To illustrate, consider the following input lines:
187 dbmclose(%verb_delim); undef %verb_delim;
188 dbmclose(%expanded); undef %expanded;
189 dbmclose(%global); undef %global;
191 Normally these would be broken into six lines, but
194 dbmclose(%verb_delim); undef %verb_delim;
195 dbmclose(%expanded); undef %expanded;
196 dbmclose(%global); undef %global;
198 -Improved formatting of complex ternary statements, with indentation
199 of nested statements.
201 return defined( $cw->{Selected} )
203 ? @{ $cw->{Selected} }
208 return defined( $cw->{Selected} )
210 ? @{ $cw->{Selected} }
214 -Text following un-parenthesized if/unless/while/until statements get a
215 full level of indentation. Suggested by Jeff Armstorng and others.
217 return $ship->chargeWeapons("phaser-canon")
218 if $encounter->description eq 'klingon'
219 and $ship->firepower >= $encounter->firepower
220 and $location->status ne 'neutral';
222 return $ship->chargeWeapons("phaser-canon")
223 if $encounter->description eq 'klingon'
224 and $ship->firepower >= $encounter->firepower
225 and $location->status ne 'neutral';
228 -Fixed bug where #line directives were being indented. Thanks to
232 -Fixed problem where an extra blank line was added after an =cut when either
233 (a) the =cut started (not stopped) a POD section, or (b) -mbl > 1.
234 Thanks to J. Robert Ray and Bill Moseley.
237 -ole (--output-line-ending) and -ple (--preserve-line-endings) should
238 now work on all systems rather than just unix systems. Thanks to Dan
241 -Fixed problem of a warning issued for multiple subs for BEGIN subs
242 and other control subs. Thanks to Heiko Eissfeldt.
244 -Fixed problem where no space was introduced between a keyword or
245 bareword and a colon, such as:
247 ( ref($result) eq 'HASH' && !%$result ) ? undef: $result;
251 -Added a utility program 'break_long_quotes.pl' to the examples directory of
252 the distribution. It breaks long quoted strings into a chain of concatenated
253 sub strings no longer than a selected length. Suggested by Michael Renner as
254 a perltidy feature but was judged to be best done in a separate program.
256 -Updated docs to remove extra < and >= from list of tokens
257 after which breaks are made by default. Thanks to Bob Kleemann.
259 -Removed improper uses of $_ to avoid conflicts with external calls, giving
260 error message similar to:
261 Modification of a read-only value attempted at
262 /usr/share/perl5/Perl/Tidy.pm line 6907.
263 Thanks to Michael Renner.
265 -Fixed problem when errorfile was not a plain filename or filehandle
266 in a call to Tidy.pm. The call
267 perltidy(source => \$input, destination => \$output, errorfile => \$err);
268 gave the following error message:
269 Not a GLOB reference at /usr/share/perl5/Perl/Tidy.pm line 3827.
270 Thanks to Michael Renner and Phillipe Bruhat.
272 -Fixed problem where -sot would not stack an opening token followed by
273 a side comment. Thanks to Jens Schicke.
275 -improved breakpoints in complex math and other long statements. Example:
278 log($n) + 0.577215664901532 + ( 1 / ( 2 * $n ) ) -
279 ( 1 / ( 12 * ( $n**2 ) ) ) + ( 1 / ( 120 * ( $n**4 ) ) );
282 log($n) + 0.577215664901532 +
284 ( 1 / ( 12 * ( $n**2 ) ) ) +
285 ( 1 / ( 120 * ( $n**4 ) ) );
287 -more robust vertical alignment of complex terminal else blocks and ternary
291 -Eliminated bug where a here-doc invoked through an 'e' modifier on a pattern
292 replacement text was not recognized. The tokenizer now recursively scans
293 replacement text (but does not reformat it).
295 -improved vertical alignment of terminal else blocks and ternary statements.
296 Thanks to Chris for the suggestion.
299 if ( IsBitmap() ) { return GetBitmap(); }
300 elsif ( IsFiles() ) { return GetFiles(); }
301 else { return GetText(); }
304 if ( IsBitmap() ) { return GetBitmap(); }
305 elsif ( IsFiles() ) { return GetFiles(); }
306 else { return GetText(); }
311 : $opts{"s"} ? 'subject'
312 : $opts{"a"} ? 'author'
318 : $opts{"s"} ? 'subject'
319 : $opts{"a"} ? 'author'
322 -improved indentation of try/catch blocks and other externally defined
323 functions accepting a block argument. Thanks to jae.
325 -Added support for Perl 5.10 features say and smartmatch.
327 -Added flag -pbp (--perl-best-practices) as an abbreviation for parameters
328 suggested in Damian Conway's "Perl Best Practices". -pbp is the same as:
330 -l=78 -i=4 -ci=4 -st -se -vt=2 -cti=0 -pt=1 -bt=1 -sbt=1 -bbt=1 -nsfs -nolq
331 -wbb="% + - * / x != == >= <= =~ !~ < > | & >= < =
332 **= += *= &= <<= &&= -= /= |= >>= ||= .= %= ^= x="
334 Please note that the -st here restricts input to standard input; use
335 -nst if necessary to override.
337 -Eliminated some needless breaks at equals signs in -lp indentation.
341 Math::Complex->make(LEFT + $x * (RIGHT - LEFT) / SIZE,
342 TOP + $y * (BOTTOM - TOP) / SIZE);
344 $c = Math::Complex->make(LEFT + $x * (RIGHT - LEFT) / SIZE,
345 TOP + $y * (BOTTOM - TOP) / SIZE);
347 A break at an equals is sometimes useful for preventing complex statements
348 from hitting the line length limit. The decision to do this was
349 over-eager in some cases and has been improved. Thanks to Royce Reece.
351 -qw quotes contained in braces, square brackets, and parens are being
352 treated more like those containers as far as stacking of tokens. Also
353 stack of closing tokens ending ');' will outdent to where the ');' would
354 have outdented if the closing stack is matched with a similar opening stack.
356 OLD: perltidy -soc -sct
357 __PACKAGE__->load_components(
363 NEW: perltidy -soc -sct
364 __PACKAGE__->load_components( qw(
368 Thanks to Aran Deltac
370 -Eliminated some undesirable or marginally desirable vertical alignments.
371 These include terminal colons, opening braces, and equals, and particularly
372 when just two lines would be aligned.
375 my $accurate_timestamps = $Stamps{lnk};
379 my $accurate_timestamps = $Stamps{lnk};
382 -Corrected a problem with -mangle in which a space would be removed
383 between a keyword and variable beginning with ::.
386 -Attribute argument lists are now correctly treated as quoted strings
387 and not formatted. This is the most important update in this version.
388 Thanks to Borris Zentner, Greg Ferguson, Steve Kirkup.
390 -Updated to recognize the defined or operator, //, to be released in Perl 10.
391 Thanks to Sebastien Aperghis-Tramoni.
393 -A useful utility perltidyrc_dump.pl is included in the examples section. It
394 will read any perltidyrc file and write it back out in a standard format
395 (though comments are lost).
397 -Added option to have perltidy read and return a hash with the contents of a
398 perltidyrc file. This may be used by Leif Eriksen's tidyview code. This
399 feature is used by the demonstration program 'perltidyrc_dump.pl' in the
402 -Improved error checking in perltidyrc files. Unknown bare words were not
405 -The --dump-options parameter now dumps parameters in the format required by a
408 -V-Strings with underscores are now recognized.
409 For example: $v = v1.2_3;
411 -cti=3 option added which gives one extra indentation level to closing
412 tokens always. This provides more predictable closing token placement
413 than cti=2. If you are using cti=2 you might want to try cti=3.
415 -To identify all left-adjusted comments as static block comments, use C<-sbcp='^#'>.
417 -New parameters -fs, -fsb, -fse added to allow sections of code between #<<<
418 and #>>> to be passed through verbatim. This is enabled by default and turned
419 off by -nfs. Flags -fsb and -fse allow other beginning and ending markers.
420 Thanks to Wolfgang Werner and Marion Berryman for suggesting this.
422 -added flag -skp to put a space between all Perl keywords and following paren.
423 The default is to only do this for certain keywords. Suggested by
426 -added flag -sfp to put a space between a function name and following paren.
427 The default is not to do this. Suggested by H.Merijn Brand.
429 -Added patch to avoid breaking GetOpt::Long::Configure set by calling program.
430 Thanks to Philippe Bruhat.
432 -An error was fixed in which certain parameters in a .perltidyrc file given
433 without the equals sign were not recognized. That is,
434 '--brace-tightness 0' gave an error but '--brace-tightness=0' worked
435 ok. Thanks to Zac Hansen.
437 -An error preventing the -nwrs flag from working was corrected. Thanks to
440 -Corrected some alignment problems with entab option.
442 -A bug with the combination of -lp and -extrude was fixed (though this
443 combination doesn't really make sense). The bug was that a line with
444 a single zero would be dropped. Thanks to Cameron Hayne.
446 -Updated Windows detection code to avoid an undefined variable.
447 Thanks to Joe Yates and Russ Jones.
449 -Improved formatting for short trailing statements following a closing paren.
450 Thanks to Joe Matarazzo.
452 -The handling of the -icb (indent closing block braces) flag has been changed
453 slightly to provide more consistent and predictable formatting of complex
454 structures. Instead of giving a closing block brace the indentation of the
455 previous line, it is now given one extra indentation level. The two methods
456 give the same result if the previous line was a complete statement, as in this
465 The change also fixes a problem with empty blocks such as:
475 -A problem with -icb was fixed in which a closing brace was misplaced when
476 it followed a quote which spanned multiple lines.
478 -Some improved breakpoints for -wba='&& || and or'
480 -Fixed problem with misaligned cuddled else in complex statements
481 when the -bar flag was also used. Thanks to Alex and Royce Reese.
483 -Corrected documentation to show that --outdent-long-comments is the default.
486 -New flag -otr (opening-token-right) is similar to -bar (braces-always-right)
487 but applies to non-structural opening tokens.
489 -new flags -sot (stack-opening-token), -sct (stack-closing-token).
493 -The default has been changed to not do syntax checking with perl.
494 Use -syn if you want it. Perltidy is very robust now, and the -syn
495 flag now causes more problems than it's worth because of BEGIN blocks
496 (which get executed with perl -c). For example, perltidy will never
497 return when trying to beautify this code if -syn is used:
499 BEGIN { 1 while { }; }
501 Although this is an obvious error, perltidy is often run on untested
502 code which is more likely to have this sort of problem. A more subtle
505 BEGIN { use FindBin; }
507 which may hang on some systems using -syn if a shared file system is
510 -Changed style -gnu to use -cti=1 instead of -cti=2 (see next item).
511 In most cases it looks better. To recover the previous format, use
514 -Added flags -cti=n for finer control of closing token indentation.
515 -cti = 0 no extra indentation (default; same as -nicp)
516 -cti = 1 enough indentation so that the closing token
517 aligns with its opening token.
518 -cti = 2 one extra indentation level if the line has the form
519 ); ]; or }; (same as -icp).
521 The new option -cti=1 works well with -lp:
525 # perltidy -lp -cti=1
527 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
528 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
531 # perltidy -lp -cti=2
533 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
534 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
536 This is backwards compatible with -icp. See revised manual for
537 details. Suggested by Mike Pennington.
539 -Added flag '--preserve-line-endings' or '-ple' to cause the output
540 line ending to be the same as in the input file, for unix, dos,
541 or mac line endings. Only works under unix. Suggested by
544 -Added flag '--output-line-ending=s' or '-ole=s' where s=dos or win,
545 unix, or mac. Only works under unix.
547 -Files with Mac line endings should now be handled properly under unix
548 and dos without being passed through a converter.
550 -You may now include 'and', 'or', and 'xor' in the list following
551 '--want-break-after' to get line breaks after those keywords rather than
552 before them. Suggested by Rainer Hochschild.
554 -Corrected problem with command line option for -vtc=n and -vt=n. The
555 equals sign was being eaten up by the Windows shell so perltidy didn't
559 -Corrected cause of warning message with recent versions of Perl:
560 "Possible precedence problem on bitwise & operator at ..."
563 -fixed bug with -html with '=for pod2html' sections, in which code/pod
564 output order was incorrect. Thanks to Tassilo von Parseval.
566 -fixed bug when the -html flag is used, in which the following error
567 message, plus others, appear:
568 did not see <body> in pod2html output
569 This was caused by a change in the format of html output by pod2html
570 VERSION 1.04 (included with perl 5.8). Thanks to Tassilo von Parseval.
572 -Fixed bug where an __END__ statement would be mistaken for a label
573 if it is immediately followed by a line with a leading colon. Thanks
576 -Implemented guessing logic for brace types when it is ambiguous. This
577 has been on the TODO list a long time. Thanks to Boris Zentner for
580 -Long options may now be negated either as '--nolong-option'
581 or '--no-long-option'. Thanks to Philip Newton for the suggestion.
583 -added flag --html-entities or -hent which controls the use of
584 Html::Entities for html formatting. Use --nohtml-entities or -nhent to
585 prevent the use of Html::Entities to encode special symbols. The
586 default is -hent. Html::Entities when formatting perl text to escape
587 special symbols. This may or may not be the right thing to do,
588 depending on browser/language combinations. Thanks to Burak Gursoy for
591 -Bareword strings with leading '-', like, '-foo' now count as 1 token
592 for horizontal tightness. This way $a{'-foo'}, $a{foo}, and $a{-foo}
593 are now all treated similarly. Thus, by default, OLD: $a{ -foo } will
594 now be NEW: $a{-foo}. Suggested by Mark Olesen.
596 -added 2 new flags to control spaces between keywords and opening parens:
597 -sak=s or --space-after-keyword=s, and
598 -nsak=s or --nospace-after-keyword=s, where 's' is a list of keywords.
600 The new default list of keywords which get a space is:
602 "my local our and or eq ne if else elsif until unless while for foreach
603 return switch case given when"
605 Use -sak=s and -nsak=s to add and remove keywords from this list,
608 Explanation: Stephen Hildrey noted that perltidy was being inconsistent
609 in placing spaces between keywords and opening parens, and sent a patch
610 to give user control over this. The above list was selected as being
611 a reasonable default keyword list. Previously, perltidy
612 had a hardwired list which also included these keywords:
614 push pop shift unshift join split die
616 but did not have 'our'. Example: if you prefer to make perltidy behave
617 exactly as before, you can include the following two lines in your
620 -sak="push pop local shift unshift join split die"
623 -Corrected html error in .toc file when -frm -html is used (extra ");
624 browsers were tolerant of it.
626 -Improved alignment of chains of binary and ?/: operators. Example:
640 -improved breakpoint choices involving '->'
642 -Corrected tokenization of things like ${#} or ${©}. For example,
643 ${©} is valid, but ${© } is a syntax error.
645 -Corrected minor tokenization errors with indirect object notation.
646 For example, 'new A::()' works now.
648 -Minor tokenization improvements; all perl code distributed with perl 5.8
649 seems to be parsed correctly except for one instance (lextest.t)
653 -Implemented scalar attributes. Thanks to Sean Tobin for noting this.
655 -Fixed glitch introduced in previous release where -pre option
656 was not outputting a leading html <pre> tag.
658 -Numerous minor improvements in vertical alignment, including the following:
660 -Improved alignment of opening braces in many cases. Needed for improved
661 switch/case formatting, and also suggested by Mark Olesen for sort/map/grep
662 formatting. For example:
667 sort { $a->[1] <=> $b->[1] }
668 map { [ $_, -M ] } @filenames;
673 sort { $a->[1] <=> $b->[1] }
674 map { [ $_, -M ] } @filenames;
676 -Eliminated alignments across unrelated statements. Example:
678 $borrowerinfo->configure( -state => 'disabled' );
679 $borrowerinfo->grid( -col => 1, -row => 0, -sticky => 'w' );
682 $borrowerinfo->configure( -state => 'disabled' );
683 $borrowerinfo->grid( -col => 1, -row => 0, -sticky => 'w' );
685 Thanks to Mark Olesen for suggesting this.
687 -Improved alignement of '='s in certain cases.
688 Thanks to Norbert Gruener for sending an example.
690 -Outdent-long-comments (-olc) has been re-instated as a default, since
691 it works much better now. Use -nolc if you want to prevent it.
693 -Added check for 'perltidy file.pl -o file.pl', which causes file.pl
694 to be lost. (The -b option should be used instead). Thanks to mreister
695 for reporting this problem.
698 -Switch/case or given/when syntax is now recognized. Its vertical alignment
699 is not great yet, but it parses ok. The words 'switch', 'case', 'given',
700 and 'when' are now treated as keywords. If this causes trouble with older
701 code, we could introduce a switch to deactivate it. Thanks to Stan Brown
702 and Jochen Schneider for recommending this.
704 -Corrected error parsing sub attributes with call parameters.
705 Thanks to Marc Kerr for catching this.
707 -Sub prototypes no longer need to be on the same line as sub names.
709 -a new flag -frm or --frames will cause html output to be in a
710 frame, with table of contents in the left panel and formatted source
711 in the right panel. Try 'perltidy -html -frm somemodule.pm' for example.
713 -The new default for -html formatting is to pass the pod through Pod::Html.
714 The result is syntax colored code within your pod documents. This can be
715 deactivated with -npod. Thanks to those who have written to discuss this,
716 particularly Mark Olesen and Hugh Myers.
718 -the -olc (--outdent-long-comments) option works much better. It now outdents
719 groups of consecutive comments together, and by just the amount needed to
720 avoid having any one line exceeding the maximum line length.
722 -block comments are now trimmed of trailing whitespace.
724 -if a directory specified with -opath does not exist, it will be created.
726 -a table of contents to packages and subs is output when -html is used.
727 Use -ntoc to prevent this.
729 -fixed an unusual bug in which a 'for' statement following a 'format'
730 statement was not correctly tokenized. Thanks to Boris Zentner for
733 -Tidy.pm is no longer dependent on modules IO::Scalar and IO::ScalarArray.
734 There were some speed issues. Suggested by Joerg Walter.
736 -The treatment of quoted wildcards (file globs) is now system-independent.
741 would match box.pl, box.pm, brinx.pm under any operating system. Of
742 course, anything unquoted will be subject to expansion by any shell.
744 -default color for keywords under -html changed from
745 SaddleBrown (#8B4513) to magenta4 (#8B008B).
747 -fixed an arg parsing glitch in which something like:
749 would trigger the help message and exit, rather than operate on the
753 -New option '-b' or '--backup-and-modify-in-place' will cause perltidy to
754 overwrite the original file with the tidied output file. The original
755 file will be saved with a '.bak' extension (which can be changed with
756 -bext=s). Thanks to Rudi Farkas for the suggestion.
758 -An index to all subs is included at the top of -html output, unless
759 only the <pre> section is written.
761 -Anchor lines of the form <a name="mysub"></a> are now inserted at key points
762 in html output, such as before sub definitions, for the convenience of
763 postprocessing scripts. Suggested by Howard Owen.
765 -The cuddled-else (-ce) flag now also makes cuddled continues, like
768 while ( ( $pack, $file, $line ) = caller( $i++ ) ) {
774 Suggested by Simon Perreault.
776 -Fixed bug in which an extra blank line was added before an =head or
777 similar pod line after an __END__ or __DATA__ line each time
778 perltidy was run. Also, an extra blank was being added after
779 a terminal =cut. Thanks to Mike Birdsall for reporting this.
782 -Fixed bug in which space was inserted in a hyphenated hash key:
783 my $val = $myhash{USER-NAME};
785 my $val = $myhash{USER -NAME};
786 Thanks to an anonymous bug reporter at sourceforge.
788 -Fixed problem with the '-io' ('--indent-only') where all lines
789 were double spaced. Thanks to Nick Andrew for reporting this bug.
791 -Fixed tokenization error in which something like '-e1' was
794 -Corrected a rare problem involving older perl versions, in which
795 a line break before a bareword caused problems with 'use strict'.
796 Thanks to Wolfgang Weisselberg for noting this.
798 -More syntax error checking added.
800 -Outdenting labels (-ola) has been made the default, in order to follow the
801 perlstyle guidelines better. It's probably a good idea in general, but
802 if you do not want this, use -nola in your .perltidyrc file.
804 -Updated rules for padding logical expressions to include more cases.
805 Thanks to Wolfgang Weisselberg for helpful discussions.
807 -Added new flag -osbc (--outdent-static-block-comments) which will
808 outdent static block comments by 2 spaces (or whatever -ci equals).
809 Requested by Jon Robison.
812 -Corrected a bug, introduced in the previous release, in which some
813 closing side comments (-csc) could have incorrect text. This is
814 annoying but will be correct the next time perltidy is run with -csc.
816 -Implemented XHTML patch submitted by Ville Skyttä.
818 -Fixed bug where whitespace was being removed between 'Bar' and '()'
819 in a use statement like:
823 Thanks to Ville Skyttä for reporting this.
825 -Whenever possible, if a logical expression is broken with leading
826 '&&', '||', 'and', or 'or', then the leading line will be padded
827 with additional space to produce alignment. This has been on the
828 todo list for a long time; thanks to Frank Steinhauer for reminding
829 me to do it. Notice the first line after the open parens here:
833 !param("rules.to.$linecount")
834 && !param("rules.from.$linecount")
835 && !param("rules.subject.$linecount")
837 param("rules.fieldname.$linecount")
838 && param("rules.fieldval.$linecount")
840 && !param("rules.size.$linecount")
841 && !param("rules.custom.$linecount")
846 !param("rules.to.$linecount")
847 && !param("rules.from.$linecount")
848 && !param("rules.subject.$linecount")
850 param("rules.fieldname.$linecount")
851 && param("rules.fieldval.$linecount")
853 && !param("rules.size.$linecount")
854 && !param("rules.custom.$linecount")
858 -Corrected a mistokenization of variables for a package with a name
859 equal to a perl keyword. For example:
863 sub qx{print "Hello from my::qx\n";}
865 In this case, the leading 'my' was mistokenized as a keyword, and a
866 space was being place between 'my' and '::'. This has been
867 corrected. Thanks to Martin Sluka for discovering this.
869 -A new flag -bol (--break-at-old-logic-breakpoints)
870 has been added to control whether containers with logical expressions
871 should be broken open. This is the default.
873 -A new flag -bok (--break-at-old-keyword-breakpoints)
874 has been added to follow breaks at old keywords which return lists,
875 such as sort and map. This is the default.
877 -A new flag -bot (--break-at-old-trinary-breakpoints) has been added to
878 follow breaks at trinary (conditional) operators. This is the default.
880 -A new flag -cab=n has been added to control breaks at commas after
881 '=>' tokens. The default is n=1, meaning break unless this breaks
882 open an existing on-line container.
884 -A new flag -boc has been added to allow existing list formatting
885 to be retained. (--break-at-old-comma-breakpoints). See updated manual.
887 -A new flag -iob (--ignore-old-breakpoints) has been added to
888 prevent the locations of old breakpoints from influencing the output
891 -Corrected problem where nested parentheses were not getting full
892 indentation. This has been on the todo list for some time; thanks
893 to Axel Rose for a snippet demonstrating this issue.
895 OLD: inner list is not indented
899 $ret->name, $user->username, $user->host,
900 $user->server->name, $user->nick, "H"
908 $ret->name, $user->username, $user->host,
909 $user->server->name, $user->nick, "H"
913 -Code cleaned up by removing the following unused, undocumented flags.
914 They should not be in any .perltidyrc files because they were just
915 experimental flags which were never documented. Most of them placed
916 artificial limits on spaces, and Wolfgang Weisselberg convinced me that
917 most of them they do more harm than good by causing unexpected results.
919 --maximum-continuation-indentation (-mci)
920 --maximum-whitespace-columns
921 --maximum-space-to-comment (-xsc)
922 --big-space-jump (-bsj)
924 -Pod file 'perltidy.pod' has been appended to the script 'perltidy', and
925 Tidy.pod has been append to the module 'Tidy.pm'. Older MakeMaker's
928 -A new flag -isbc has been added for more control on comments. This flag
929 has the effect that if there is no leading space on the line, then the
930 comment will not be indented, and otherwise it may be. If both -ibc and
931 -isbc are set, then -isbc takes priority. Thanks to Frank Steinhauer
934 -A new document 'stylekey.pod' has been created to quickly guide new users
935 through the maze of perltidy style parameters. An html version is
936 on the perltidy web page. Take a look! It should be very helpful.
938 -Parameters for controlling 'vertical tightness' have been added:
939 -vt and -vtc are the main controls, but finer control is provided
940 with -pvt, -pcvt, -bvt, -bcvt, -sbvt, -sbcvt. Block brace vertical
941 tightness controls have also been added.
942 See updated manual and also see 'stylekey.pod'. Simple examples:
944 # perltidy -lp -vt=1 -vtc=1
945 @month_of_year = ( 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
946 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec' );
948 # perltidy -lp -vt=1 -vtc=0
949 @month_of_year = ( 'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
950 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'
953 -Lists which do not format well in uniform columns are now better
954 identified and formated.
957 return $c->create( 'polygon', $x, $y, $x + $ruler_info{'size'},
958 $y + $ruler_info{'size'}, $x - $ruler_info{'size'},
959 $y + $ruler_info{'size'} );
964 $x + $ruler_info{'size'},
965 $y + $ruler_info{'size'},
966 $x - $ruler_info{'size'},
967 $y + $ruler_info{'size'}
971 radlablist($f1, pad('Initial', $p), $b->{Init}->get_panel_ref, 'None ',
972 'None', 'Default', 'Default', 'Simple', 'Simple');
976 $b->{Init}->get_panel_ref,
977 'None ', 'None', 'Default', 'Default', 'Simple', 'Simple');
979 -Corrected problem where an incorrect html filename was generated for
980 external calls to Tidy.pm module. Fixed incorrect html title when
981 Tidy.pm is called with IO::Scalar or IO::Array source.
983 -Output file permissons are now set as follows. An output script file
984 gets the same permission as the input file, except that owner
985 read/write permission is added (otherwise, perltidy could not be
986 rerun). Html output files use system defaults. Previously chmod 0755
987 was used in all cases. Thanks to Mark Olesen for bringing this up.
989 -Missing semicolons will not be added in multi-line blocks of type
990 sort, map, or grep. This brings perltidy into closer agreement
991 with common practice. Of course, you can still put semicolons
992 there if you like. Thanks to Simon Perreault for a discussion of this.
994 -Most instances of extra semicolons are now deleted. This is
995 particularly important if the -csc option is used. Thanks to Wolfgang
996 Weisselberg for noting this. For example, the following line
997 (produced by 'h2xs' :) has an extra semicolon which will now be
1000 BEGIN { plan tests => 1 };
1002 -New parameter -csce (--closing-side-comment-else-flag) can be used
1003 to control what text is appended to 'else' and 'elsif' blocks.
1004 Default is to just add leading 'if' text to an 'else'. See manual.
1006 -The -csc option now labels 'else' blocks with additinal information
1007 from the opening if statement and elsif statements, if space.
1008 Thanks to Wolfgang Weisselberg for suggesting this.
1010 -The -csc option will now remove any old closing side comments
1011 below the line interval threshold. Thanks to Wolfgang Weisselberg for
1014 -The abbreviation feature, which was broken in the previous version,
1015 is now fixed. Thanks to Michael Cartmell for noting this.
1017 -Vertical alignment is now done for '||=' .. somehow this was
1021 -This version uses modules for the first time, and a standard perl
1022 Makefile.PL has been supplied. However, perltidy may still be
1023 installed as a single script, without modules. See INSTALL for
1026 -The man page 'perl2web' has been merged back into the main 'perltidy'
1027 man page to simplify installation. So you may remove that man page
1028 if you have an older installation.
1030 -Added patch from Axel Rose for MacPerl. The patch prompts the user
1031 for command line arguments before calling the module
1032 Perl::Tidy::perltidy.
1034 -Corrected bug with '-bar' which was introduced in the previous
1035 version. A closing block brace was being indented. Thanks to
1036 Alexandros M Manoussakis for reporting this.
1038 -New parameter '--entab-leading-whitespace=n', or '-et=n', has been
1039 added for those who prefer tabs. This behaves different from the
1040 existing '-t' parameter; see updated man page. Suggested by Mark
1043 -New parameter '--perl-syntax-check-flags=s' or '-pcsf=s' can be
1044 used to change the flags passed to perltidy in a syntax check.
1045 See updated man page. Suggested by Mark Olesen.
1047 -New parameter '--output-path=s' or '-opath=s' will cause output
1048 files to be placed in directory s. See updated man page. Thanks for
1049 Mark Olesen for suggesting this.
1051 -New parameter --dump-profile (or -dpro) will dump to
1052 standard output information about the search for a
1053 configuration file, the name of whatever configuration file
1054 is selected, and its contents. This should help debugging
1055 config files, especially on different Windows systems.
1057 -The -w parameter now notes possible errors of the form:
1059 $comment = s/^\s*(\S+)\..*/$1/; # trim whitespace
1061 -Corrections added for a leading ':' and for leaving a leading 'tcsh'
1062 line untouched. Mark Olesen reported that lines of this form were
1063 accepted by perl but not by perltidy:
1065 : # use -*- perl -*-
1066 eval 'exec perl -wS $0 "$@"' # shell should exec 'perl'
1067 unless 1; # but Perl should skip this one
1069 Perl will silently swallow a leading colon on line 1 of a
1070 script, and now perltidy will do likewise. For example,
1071 this is a valid script, provided that it is the first line,
1074 : print "Hello World\n";
1076 Also, perltidy will now mark a first line with leading ':' followed by
1077 '#' as type SYSTEM (just as a #! line), not to be formatted.
1079 -List formatting improved for certain lists with special
1080 initial terms, such as occur with 'printf', 'sprintf',
1081 'push', 'pack', 'join', 'chmod'. The special initial term is
1082 now placed on a line by itself. For example, perltidy -gnu
1086 "C4", hex($SourceAddr[0]),
1087 hex($SourceAddr[1]), hex($SourceAddr[2]),
1093 hex($SourceAddr[0]), hex($SourceAddr[1]),
1094 hex($SourceAddr[2]), hex($SourceAddr[3]));
1098 @{$$self{states}}, '64', '66', '68',
1099 '70', '72', '74', '76',
1100 '78', '80', '82', '84',
1101 '86', '88', '90', '92',
1102 '94', '96', '98', '100',
1109 '64', '66', '68', '70', '72', '74', '76',
1110 '78', '80', '82', '84', '86', '88', '90',
1111 '92', '94', '96', '98', '100', '102', '104'
1114 -Lists of complex items, such as matricies, are now detected
1115 and displayed with just one item per row:
1118 $this->{'CURRENT'}{'gfx'}{'MatrixSkew'} = Text::PDF::API::Matrix->new(
1119 [ 1, tan( deg2rad($a) ), 0 ], [ tan( deg2rad($b) ), 1, 0 ],
1124 $this->{'CURRENT'}{'gfx'}{'MatrixSkew'} = Text::PDF::API::Matrix->new(
1125 [ 1, tan( deg2rad($a) ), 0 ],
1126 [ tan( deg2rad($b) ), 1, 0 ],
1130 -The perl syntax check will be turned off for now when input is from
1131 standard input or standard output. The reason is that this requires
1132 temporary files, which has produced far too many problems during
1133 Windows testing. For example, the POSIX module under Windows XP/2000
1134 creates temporary names in the root directory, to which only the
1135 administrator should have permission to write.
1137 -Merged patch sent by Yves Orton to handle appropriate
1138 configuration file locations for different Windows varieties
1139 (2000, NT, Me, XP, 95, 98).
1141 -Added patch to properly handle a for/foreach loop without
1142 parens around a list represented as a qw. I didn't know this
1143 was possible until Wolfgang Weisselberg pointed it out:
1145 foreach my $key qw\Uno Due Tres Quadro\ {
1149 But Perl will give a syntax error without the $ variable; ie this will
1152 foreach qw\Uno Due Tres Quadro\ {
1156 -Merged Windows version detection code sent by Yves Orton. Perltidy
1157 now automatically turns off syntax checking for Win 9x/ME versions,
1158 and this has solved a lot of robustness problems. These systems
1159 cannot reliably handle backtick operators. See man page for
1162 -Merged VMS filename handling patch sent by Michael Cartmell. (Invalid
1163 output filenames were being created in some cases).
1165 -Numerous minor improvements have been made for -lp style indentation.
1167 -Long C-style 'for' expressions will be broken after each ';'.
1169 'perltidy -gnu' gives:
1172 for ($status = $db->seq($key, $value, R_CURSOR()) ; $status == 0
1173 and $key eq $origkey ; $status = $db->seq($key, $value, R_NEXT()))
1176 for ($status = $db->seq($key, $value, R_CURSOR()) ;
1177 $status == 0 and $key eq $origkey ;
1178 $status = $db->seq($key, $value, R_NEXT()))
1180 -For the -lp option, a single long term within parens
1181 (without commas) now has better alignment. For example,
1185 $self->throw("Must specify a known host, not $location,"
1186 . " possible values ("
1187 . join (",", sort keys %hosts) . ")");
1190 $self->throw("Must specify a known host, not $location,"
1191 . " possible values ("
1192 . join (",", sort keys %hosts) . ")");
1195 -This version is about 20 percent faster than the previous
1196 version as a result of optimization work. The largest gain
1197 came from switching to a dispatch hash table in the
1200 -perltidy -html will check to see if HTML::Entities is
1201 installed, and if so, it will use it to encode unsafe
1204 -Added flag -oext=ext to change the output file extension to
1205 be different from the default ('tdy' or 'html'). For
1208 perltidy -html -oext=htm filename
1210 will produce filename.htm
1212 -Added flag -cscw to issue warnings if a closing side comment would replace
1213 an existing, different side comments. See the man page for details.
1214 Thanks to Peter Masiar for helpful discussions.
1216 -Corrected tokenization error of signed hex/octal/binary numbers. For
1217 example, the first hex number below would have been parsed correctly
1218 but the second one was not:
1219 if ( ( $tmp >= 0x80_00_00 ) || ( $tmp < -0x80_00_00 ) ) { }
1221 -'**=' was incorrectly tokenized as '**' and '='. This only
1222 caused a problem with the -extrude opton.
1224 -Corrected a divide by zero when -extrude option is used
1226 -The flag -w will now contain all errors reported by 'perl -c' on the
1227 input file, but otherwise they are not reported. The reason is that
1228 perl will report lots of problems and syntax errors which are not of
1229 interest when only a small snippet is being formatted (such as missing
1230 modules and unknown bare words). Perltidy will always report all
1231 significant syntax errors that it finds, such as unbalanced braces,
1232 unless the -q (quiet) flag is set.
1234 -Merged modifications created by Hugh Myers into perltidy.
1235 These include a 'streamhandle' routine which allows perltidy
1236 as a module to operate on input and output arrays and strings
1237 in addition to files. Documentation and new packaging as a
1238 module should be ready early next year; This is an elegant,
1239 powerful update; many thanks to Hugh for contributing it.
1242 -added a tentative patch which tries to keep any existing breakpoints
1243 at lines with leading keywords map,sort,eval,grep. The idea is to
1244 improve formatting of sequences of list operations, as in a schwartzian
1248 my @sorted = map { $_->[0] }
1249 sort { $a->[1] <=> $b->[1] }
1250 map { [ $_, rand ] } @list;
1254 map { $_->[0] } sort { $a->[1] <=> $b->[1] } map { [ $_, rand ] } @list;
1257 my @sorted = map { $_->[0] }
1258 sort { $a->[1] <=> $b->[1] }
1259 map { [ $_, rand ] } @list;
1261 The new alignment is not as nice as the input, but this is an improvement.
1262 Thanks to Yves Orton for this suggestion.
1264 -modified indentation logic so that a line with leading opening paren,
1265 brace, or square bracket will never have less indentation than the
1266 line with the corresponding opening token. Here's a simple example:
1270 -text => "New Document",
1271 -command => \&new_document
1277 Note how the closing ');' is lined up with the first line, even
1278 though it closes a paren in the 'pack' line. That seems wrong.
1282 -text => "New Document",
1283 -command => \&new_document
1289 This seems nicer: you can up-arrow with an editor and arrive at the
1290 opening 'pack' line.
1292 -corrected minor glitch in which cuddled else (-ce) did not get applied
1293 to an 'unless' block, which should look like this:
1301 Thanks to Jeremy Mates for reporting this.
1303 -The man page has been reorganized to parameters easier to find.
1305 -Added check for multiple definitions of same subroutine. It is easy
1306 to introduce this problem when cutting and pasting. Perl does not
1307 complain about it, but it can lead to disaster.
1309 -The command -pro=filename or -profile=filename may be used to specify a
1310 configuration file which will override the default name of .perltidyrc.
1311 There must not be a space on either side of the '=' sign. I needed
1312 this to be able to easily test perltidy with a variety of different
1313 configuration files.
1315 -Side comment alignment has been improved somewhat across frequent level
1316 changes, as in short if/else blocks. Thanks to Wolfgang Weisselberg
1317 for pointing out this problem. For example:
1320 if ( ref $self ) { # Called as a method
1323 else { # Regular procedure call
1329 if ( ref $self ) { # Called as a method
1332 else { # Regular procedure call
1337 -New command -ssc (--static-side-comment) and related command allows
1338 side comments to be spaced close to preceding character. This is
1339 useful for displaying commented code as side comments.
1341 -New command -csc (--closing-side-comment) and several related
1342 commands allow comments to be added to (and deleted from) any or all
1343 closing block braces. This can be useful if you have to maintain large
1344 programs, especially those that you didn't write. See updated man page.
1345 Thanks to Peter Masiar for this suggestion. For a simple example:
1350 if ( !defined( $_[0] ) ) {
1351 print("Hello, World\n");
1354 print( $_[0], "\n" );
1358 This added '## end sub foo' to the closing brace.
1359 To remove it, perltidy -ncsc.
1361 -New commands -ola, for outdenting labels, and -okw, for outdenting
1362 selected control keywords, were implemented. See the perltidy man
1363 page for details. Thanks to Peter Masiar for this suggestion.
1365 -Hanging side comment change: a comment will not be considered to be a
1366 hanging side comment if there is no leading whitespace on the line.
1367 This should improve the reliability of identifying hanging side comments.
1368 Thanks to Peter Masiar for this suggestion.
1370 -Two new commands for outdenting, -olq (outdent-long-quotes) and -olc
1371 (outdent-long-comments), have been added. The original -oll
1372 (outdent-long-lines) remains, and now is an abbreviation for -olq and -olc.
1373 The new default is just -olq. This was necessary to avoid inconsistency with
1374 the new static block comment option.
1376 -Static block comments: to provide a way to display commented code
1377 better, the convention is used that comments with a leading '##' should
1378 not be formatted as usual. Please see '-sbc' (or '--static-block-comment')
1379 for documentation. It can be deactivated with with -nsbc, but
1380 should not normally be necessary. Thanks to Peter Masiar for this
1383 -Two changes were made to help show structure of complex lists:
1384 (1) breakpoints are forced after every ',' in a list where any of
1385 the list items spans multiple lines, and
1386 (2) List items which span multiple lines now get continuation indentation.
1388 The following example illustrates both of these points. Many thanks to
1389 Wolfgang Weisselberg for this snippet and a discussion of it; this is a
1390 significant formatting improvement. Note how it is easier to see the call
1391 parameters in the NEW version:
1394 assert( __LINE__, ( not defined $check )
1397 or $check eq "old", "Error in parameters",
1398 defined $old_new ? ( ref $old_new ? ref $old_new : $old_new ) : "undef",
1399 defined $db_new ? ( ref $db_new ? ref $db_new : $db_new ) : "undef",
1400 defined $old_db ? ( ref $old_db ? ref $old_db : $old_db ) : "undef" );
1405 ( not defined $check )
1409 "Error in parameters",
1410 defined $old_new ? ( ref $old_new ? ref $old_new : $old_new ) : "undef",
1411 defined $db_new ? ( ref $db_new ? ref $db_new : $db_new ) : "undef",
1412 defined $old_db ? ( ref $old_db ? ref $old_db : $old_db ) : "undef"
1415 Another example shows how this helps displaying lists:
1418 %{ $self->{COMPONENTS} } = (
1420 { type => 'name', adj => 'yes', font => 'Helvetica', 'index' => 0 },
1422 { type => 'road', adj => 'yes', font => 'Helvetica', 'index' => 2 },
1425 The structure is clearer with the added indentation:
1428 %{ $self->{COMPONENTS} } = (
1430 { type => 'name', adj => 'yes', font => 'Helvetica', 'index' => 0 },
1432 { type => 'road', adj => 'yes', font => 'Helvetica', 'index' => 2 },
1435 -The structure of nested logical expressions is now displayed better.
1436 Thanks to Wolfgang Weisselberg for helpful discussions. For example,
1437 note how the status of the final 'or' is displayed in the following:
1441 and null( $op->sibling )
1442 and $op->ppaddr eq "pp_null"
1443 and class($op) eq "UNOP"
1444 and ( ( $op->first->ppaddr =~ /^pp_(and|or)$/
1445 and $op->first->first->sibling->ppaddr eq "pp_lineseq" )
1446 or ( $op->first->ppaddr eq "pp_lineseq"
1447 and not null $op->first->first->sibling
1448 and $op->first->first->sibling->ppaddr eq "pp_unstack" ) ) );
1453 and null( $op->sibling )
1454 and $op->ppaddr eq "pp_null"
1455 and class($op) eq "UNOP"
1458 $op->first->ppaddr =~ /^pp_(and|or)$/
1459 and $op->first->first->sibling->ppaddr eq "pp_lineseq"
1461 or ( $op->first->ppaddr eq "pp_lineseq"
1462 and not null $op->first->first->sibling
1463 and $op->first->first->sibling->ppaddr eq "pp_unstack" )
1467 -A break will always be put before a list item containing a comma-arrow.
1468 This will improve formatting of mixed lists of this form:
1472 'text', 225, 20, -text => 'A Simple Plot',
1480 -text => 'A Simple Plot',
1485 -For convenience, the command -dac (--delete-all-comments) now also
1486 deletes pod. Likewise, -tac (--tee-all-comments) now also sends pod
1487 to a '.TEE' file. Complete control over the treatment of pod and
1488 comments is still possible, as described in the updated help message
1491 -The logic which breaks open 'containers' has been rewritten to be completely
1492 symmetric in the following sense: if a line break is placed after an opening
1493 {, [, or (, then a break will be placed before the corresponding closing
1494 token. Thus, a container either remains closed or is completely cracked
1497 -Improved indentation of parenthesized lists. For example,
1502 atan2( $GPSTempCompLong - $GPSLongitude,
1503 $GPSLatitude - $GPSTempCompLat ) * 180 / 3.14159265 );
1506 $GPSCompCourse = int(
1508 $GPSTempCompLong - $GPSLongitude,
1509 $GPSLatitude - $GPSTempCompLat
1510 ) * 180 / 3.14159265
1513 Further improvements will be made in future releases.
1515 -Some improvements were made in formatting small lists.
1517 -Correspondence between Input and Output line numbers reported in a
1518 .LOG file should now be exact. They were sometimes off due to the size
1519 of intermediate buffers.
1521 -Corrected minor tokenization error in which a ';' in a foreach loop
1522 control was tokenized as a statement termination, which forced a
1535 foreach ( $i = 0 ; $i <= 10 ; $i += 2 ) {
1539 -Corrected a problem with reading config files, in which quote marks were not
1540 stripped. As a result, something like -wba="&& . || " would have the leading
1541 quote attached to the && and not work correctly. A workaround for older
1542 versions is to place a space around all tokens within the quotes, like this:
1545 -Removed any existing space between a label and its ':'
1548 This was necessary because the label and its colon are a single token.
1550 -Corrected tokenization error for the following (highly non-recommended)
1552 $user = @vars[1] / 100;
1554 -Resolved cause of a difference between perltidy under perl v5.6.1 and
1555 5.005_03; the problem was different behavior of \G regex position
1559 -Corrected a bug in which a break was not being made after a full-line
1560 comment within a short eval/sort/map/grep block. A flag was not being
1561 zeroed. The syntax error check catches this. Here is a snippet which
1562 illustrates the bug:
1565 #open Socket to Dispatcher
1566 $sock = &OpenSocket;
1569 The formatter mistakenly thought that it had found the following
1572 eval {#open Socket to Dispatcher$sock = &OpenSocket; };
1574 The patch fixes this. Many thanks to Henry Story for reporting this bug.
1576 -Changes were made to help diagnose and resolve problems in a
1578 (1) processing of command parameters has been into two separate
1579 batches so that any errors in a .perltidyrc file can be localized.
1580 (2) commands --help, --version, and as many of the --dump-xxx
1581 commands are handled immediately, without any command line processing
1583 (3) Perltidy will ignore any commands in the .perltidyrc file which
1584 cause immediate exit. These are: -h -v -ddf -dln -dop -dsn -dtt
1585 -dwls -dwrs -ss. Thanks to Wolfgang Weisselberg for helpful
1586 suggestions regarding these updates.
1588 -Syntax check has been reinstated as default for MSWin32 systems. This
1589 way Windows 2000 users will get syntax check by default, which seems
1590 like a better idea, since the number of Win 95/98 systems will be
1591 decreasing over time. Documentation revised to warn Windows 95/98
1592 users about the problem with empty '&1'. Too bad these systems
1593 all report themselves as MSWin32.
1596 -Fixed tokenization error in which a method call of the form
1600 got a space before the '::' like this:
1604 Thanks to David Holden for reporting this.
1606 -Added -html control over pod text, using a new abbreviation 'pd'. See
1607 updated perl2web man page. The default is to use the color of a comment,
1608 but italicized. Old .css style sheets will need a new line for
1609 .pd to use this. The old color was the color of a string, and there
1612 -.css lines are now printed in sorted order.
1614 -Fixed interpolation problem where html files had '$input_file' as title
1615 instead of actual input file name. Thanks to Simon Perreault for finding
1616 this and sending a patch, and also to Tobias Weber.
1618 -Breaks will now have the ':' placed at the start of a line,
1619 one per line by default because this shows logical structure
1620 more clearly. This coding has been completely redone. Some
1621 examples of new ?/: formatting:
1624 wantarray ? map( $dir::cwd->lookup($_)->path, @_ ) :
1625 $dir::cwd->lookup( $_[0] )->path;
1629 ? map( $dir::cwd->lookup($_)->path, @_ )
1630 : $dir::cwd->lookup( $_[0] )->path;
1636 } : { a => 6, b => 8 };
1644 : { a => 6, b => 8 };
1647 $self->note($self->{skip} ? "Hunk #$self->{hunk} ignored at 1.\n" :
1648 "Hunk #$self->{hunk} failed--$@");
1651 $self->note($self->{skip}
1652 ? "Hunk #$self->{hunk} ignored at 1.\n"
1653 : "Hunk #$self->{hunk} failed--$@");
1657 $opts{"t"} ? 'title' :
1658 $opts{"s"} ? 'subject' : $opts{"a"} ? 'author' : 'title';
1662 $opts{"t"} ? 'title'
1663 : $opts{"s"} ? 'subject'
1664 : $opts{"a"} ? 'author'
1667 You can use -wba=':' to recover the previous default which placed ':'
1668 at the end of a line. Thanks to Michael Cartmell for helpful
1669 discussions and examples.
1671 -Tokenizer updated to do syntax checking for matched ?/: pairs. Also,
1672 the tokenizer now outputs a unique serial number for every balanced
1673 pair of brace types and ?/: pairs. This greatly simplifies the
1676 -Long lines with repeated 'and', 'or', '&&', '||' will now have
1677 one such item per line. For example:
1680 if ( $opt_d || $opt_m || $opt_p || $opt_t || $opt_x
1681 || ( -e $archive && $opt_r ) )
1683 ( $pAr, $pNames ) = readAr($archive);
1692 || ( -e $archive && $opt_r ) )
1694 ( $pAr, $pNames ) = readAr($archive);
1698 if ( $vp->{X0} + 4 <= $x && $vp->{X0} + $vp->{W} - 4 >= $x
1699 && $vp->{Y0} + 4 <= $y && $vp->{Y0} + $vp->{H} - 4 >= $y )
1702 if ( $vp->{X0} + 4 <= $x
1703 && $vp->{X0} + $vp->{W} - 4 >= $x
1704 && $vp->{Y0} + 4 <= $y
1705 && $vp->{Y0} + $vp->{H} - 4 >= $y )
1707 -Long lines with multiple concatenated tokens will have concatenated
1708 terms (see below) placed one per line, except for short items. For
1713 "Device type:" . $ib->family . " ID:" . $ib->serial . " CRC:"
1714 . $ib->crc . ": " . $ib->model() . "\n";
1717 $report .= "Device type:"
1718 . $ib->family . " ID:"
1719 . $ib->serial . " CRC:"
1721 . $ib->crc . ": " . "\n";
1723 NOTE: at present 'short' means 8 characters or less. There is a
1724 tentative flag to change this (-scl), but it is undocumented and
1725 is likely to be changed or removed later, so only use it for testing.
1726 In the above example, the tokens " ID:", " CRC:", and "\n" are below
1729 -If a line which is short enough to fit on a single line was
1730 nevertheless broken in the input file at a 'good' location (see below),
1731 perltidy will try to retain a break. For example, the following line
1732 will be formatted as:
1735 or die "Cannot open $file ($!)";
1737 if it was broken in the input file, and like this if not:
1739 open SUM, "<$file" or die "Cannot open $file ($!)";
1741 GOOD: 'good' location means before 'and','or','if','unless','&&','||'
1743 The reason perltidy does not just always break at these points is that if
1744 there are multiple, similar statements, this would preclude alignment. So
1745 rather than check for this, perltidy just tries to follow the input style,
1746 in the hopes that the author made a good choice. Here is an example where
1747 we might not want to break before each 'if':
1749 ($Locale, @Locale) = ($English, @English) if (@English > @Locale);
1750 ($Locale, @Locale) = ($German, @German) if (@German > @Locale);
1751 ($Locale, @Locale) = ($French, @French) if (@French > @Locale);
1752 ($Locale, @Locale) = ($Spanish, @Spanish) if (@Spanish > @Locale);
1754 -Added wildcard file expansion for systems with shells which lack this.
1755 Now 'perltidy *.pl' should work under MSDOS/Windows. Thanks to Hugh Myers
1756 for suggesting this. This uses builtin glob() for now; I may change that.
1758 -Added new flag -sbl which, if specified, overrides the value of -bl
1759 for opening sub braces. This allows formatting of this type:
1765 if (!defined($_[0])) {
1766 print("Hello, World\n");
1772 Requested by Don Alexander.
1774 -Fixed minor parsing error which prevented a space after a $$ variable
1775 (pid) in some cases. Thanks to Michael Cartmell for noting this.
1780 -Improved line break choices 'and' and 'or' to display logic better.
1784 exists $self->{'build_dir'} and push @e,
1785 "Unwrapped into directory $self->{'build_dir'}";
1788 exists $self->{'build_dir'}
1789 and push @e, "Unwrapped into directory $self->{'build_dir'}";
1791 -Fixed error of multiple use of abbreviatioin '-dsc'. -dsc remains
1792 abbreviation for delete-side-comments; -dsm is new abbreviation for
1795 -Corrected and updated 'usage' help routine. Thanks to Slaven Rezic for
1798 -The default for Windows is, for now, not to do a 'perl -c' syntax
1799 check (but -syn will activate it). This is because of problems with
1800 command.com. James Freeman sent me a patch which tries to get around
1801 the problems, and it works in many cases, but testing revealed several
1802 issues that still need to be resolved. So for now, the default is no
1803 syntax check for Windows.
1805 -I added a -T flag when doing perl -c syntax check.
1806 This is because I test it on a large number of scripts from sources
1807 unknown, and who knows what might be hidden in initialization blocks?
1808 Also, deactivated the syntax check if perltidy is run as root. As a
1809 benign example, running the previous version of perltidy on the
1810 following file would cause it to disappear:
1813 print "Bye, bye baby!\n";
1817 The new version will not let that happen.
1819 -I am contemplating (but have not yet implemented) making '-lp' the
1820 default indentation, because it is stable now and may be closer to how
1821 perl is commonly formatted. This could be in the next release. The
1822 reason that '-lp' was not the original default is that the coding for
1823 it was complex and not ready for the initial release of perltidy. If
1824 anyone has any strong feelings about this, I'd like to hear. The
1825 current default could always be recovered with the '-nlp' flag.
1829 - sub definition names are now specially colored, red by default.
1830 The letter 'm' is used to identify them.
1831 - keyword 'sub' now has color of other keywords.
1832 - restored html keyword color to __END__ and __DATA__, which was
1833 accidentally removed in the previous version.
1835 -A new -se (--standard-error-output) flag has been implemented and
1836 documented which causes all errors to be written to standard output
1837 instead of a .ERR file.
1839 -A new -w (--warning-output) flag has been implemented and documented
1840 which causes perltidy to output certain non-critical messages to the
1841 error output file, .ERR. These include complaints about pod usage,
1842 for example. The default is to not include these.
1844 NOTE: This replaces an undocumented -w=0 or --warning-level flag
1845 which was tentatively introduced in the previous version to avoid some
1846 unwanted messages. The new default is the same as the old -w=0, so
1847 that is no longer needed.
1849 -Improved syntax checking and corrected tokenization of functions such
1850 as rand, srand, sqrt, ... These can accept either an operator or a term
1851 to their right. This has been corrected.
1853 -Corrected tokenization of semicolon: testing of the previous update showed
1854 that the semicolon in the following statement was being mis-tokenized. That
1855 did no harm, other than adding an extra blank space, but has been corrected.
1857 for (sort {strcoll($a,$b);} keys %investments) {
1861 -New syntax check: after wasting 5 minutes trying to resolve a syntax
1862 error in which I had an extra terminal ';' in a complex for (;;) statement,
1863 I spent a few more minutes adding a check for this in perltidy so it won't
1866 -The behavior of --break-before-subs (-bbs) and --break-before-blocks
1867 (-bbb) has been modified. Also, a new control parameter,
1868 --long-block-line-count=n (-lbl=n) has been introduced to give more
1869 control on -bbb. This was previously a hardwired value. The reason
1870 for the change is to reduce the number of unwanted blank lines that
1871 perltidy introduces, and make it less erratic. It's annoying to remove
1872 an unwanted blank line and have perltidy put it back. The goal is to
1873 be able to sprinkle a few blank lines in that dense script you
1874 inherited from Bubba. I did a lot of experimenting with different
1875 schemes for introducing blank lines before and after code blocks, and
1876 decided that there is no really good way to do it. But I think the new
1877 scheme is an improvement. You can always deactivate this with -nbbb.
1878 I've been meaning to work on this; thanks to Erik Thaysen for bringing
1881 -The .LOG file is seldom needed, and I get tired of deleting them, so
1882 they will now only be automatically saved if perltidy thinks that it
1883 made an error, which is almost never. You can still force the logfile
1884 to be saved with -log or -g.
1886 -Improved method for computing number of columns in a table. The old
1887 method always tried for an even number. The new method allows odd
1888 numbers when it is obvious that a list is not a hash initialization
1892 $name, $xsargs, $parobjs, $optypes,
1893 $hasp2child, $pmcode, $hdrcode, $inplacecode,
1894 $globalnew, $callcopy
1899 $name, $xsargs, $parobjs, $optypes, $hasp2child,
1900 $pmcode, $hdrcode, $inplacecode, $globalnew, $callcopy
1904 -I fiddled with the list threshold adjustment, and some small lists
1905 look better now. Here is the change for one of the lists in test file
1909 ("in", "in", "pt", "pt", "pc", "pi", "mm", "mm", "cm", "cm", "\\hsize", "%",
1910 "\\vsize", "%", "\\textwidth", "%", "\\textheight", "%");
1914 "in", "in", "pt", "pt", "pc", "pi",
1915 "mm", "mm", "cm", "cm", "\\hsize", "%",
1916 "\\vsize", "%", "\\textwidth", "%", "\\textheight", "%"
1919 -Improved -lp formatting at '=' sign. A break was always being added after
1920 the '=' sign in a statement such as this, (to be sure there was enough room
1921 for the parameters):
1926 $biblionumber, $constraint,
1930 The updated version doesn't do this unless the space is really needed:
1932 new: my $fee = CalcReserveFee(
1934 $biblionumber, $constraint,
1938 -I updated the tokenizer to allow $#+ and $#-, which seem to be new to
1939 Perl 5.6. Some experimenting with a recent version of Perl indicated
1940 that it allows these non-alphanumeric '$#' array maximum index
1941 varaibles: $#: $#- $#+ so I updated the parser accordingly. Only $#:
1942 seems to be valid in older versions of Perl.
1944 -Fixed a rare formatting problem with -lp (and -gnu) which caused
1945 excessive indentation.
1947 -Many additional syntax checks have been added.
1949 -Revised method for testing here-doc target strings; the following
1950 was causing trouble with a regex test because of the '*' characters:
1954 Perl seems to allow almost anything to be a here doc target, so an
1955 exact string comparison is now used.
1957 -Made update to allow underscores in binary numbers, like '0b1100_0000'.
1959 -Corrected problem with scanning certain module names; a blank space was
1960 being inserted after 'warnings' in the following:
1961 use warnings::register;
1962 The problem was that warnings (and a couple of other key modules) were
1963 being tokenized as keywords. They should have just been identifiers.
1965 -Corrected tokenization of indirect objects after sort, system, and exec,
1966 after testing produced an incorrect error message for the following
1968 print sort $sortsubref @list;
1970 -Corrected minor problem where a line after a format had unwanted
1971 extra continuation indentation.
1973 -Delete-block-comments (and -dac) now retain any leading hash-bang line
1975 -Update for -lp (and -gnu) to not align the leading '=' of a list
1976 with a previous '=', since this interferes with alignment of parameters.
1978 old: my $hireDay = new Date;
1985 new: my $hireDay = new Date;
1992 -Modifications made to display tables more compactly when possible,
1993 without adding lines. For example,
1995 '1', "I", '2', "II", '3', "III", '4', "IV",
1996 '5', "V", '6', "VI", '7', "VII", '8', "VIII",
1999 '1', "I", '2', "II", '3', "III",
2000 '4', "IV", '5', "V", '6', "VI",
2001 '7', "VII", '8', "VIII", '9', "IX"
2003 -Corrected minor bug in which -pt=2 did not keep the right paren tight
2004 around a '++' or '--' token, like this:
2006 for ($i = 0 ; $i < length $key ; $i++ )
2008 The formatting for this should be, and now is:
2010 for ($i = 0 ; $i < length $key ; $i++)
2012 Thanks to Erik Thaysen for noting this.
2014 -Discovered a new bug involving here-docs during testing! See BUGS.html.
2016 -Finally fixed parsing of subroutine attributes (A Perl 5.6 feature).
2017 However, the attributes and prototypes must still be on the same line
2021 -Corrected minor, uncommon bug found during routine testing, in which a
2022 blank got inserted between a function name and its opening paren after
2023 a file test operator, but only in the case that the function had not
2024 been previously seen. Perl uses the existance (or lack thereof) of
2025 the blank to guess if it is a function call. That is,
2026 if (-l pid_filename()) {
2028 if (-l pid_filename ()) {
2029 which is a syntax error if pid_filename has not been seen by perl.
2031 -If the AutoLoader module is used, perltidy will continue formatting
2032 code after seeing an __END__ line. Use -nlal to deactivate this feature.
2033 Likewise, if the SelfLoader module is used, perltidy will continue
2034 formatting code after seeing a __DATA__ line. Use -nlsl to
2035 deactivate this feature. Thanks to Slaven Rezic for this suggestion.
2037 -pod text after __END__ and __DATA__ is now identified by perltidy
2038 so that -dp works correctly. Thanks to Slaven Rezic for this suggestion.
2040 -The first $VERSION line which might be eval'd by MakeMaker
2041 is now passed through unchanged. Use -npvl to deactivate this feature.
2042 Thanks to Manfred Winter for this suggestion.
2044 -Improved indentation of nested parenthesized expressions. Tests have
2045 given favorable results. Thanks to Wolfgang Weisselberg for helpful
2049 -Fixed a very rare problem in which an unwanted semicolon was inserted
2050 due to misidentification of anonymous hash reference curly as a code
2051 block curly. (No instances of this have been reported; I discovered it
2052 during testing). A workaround for older versions of perltidy is to use
2055 -Added -icb (-indent-closing-brace) parameter to indent a brace which
2056 terminates a code block to the same level as the previous line.
2057 Suggested by Andrew Cutler. For example,
2066 -Rewrote error message triggered by an unknown bareword in a print or
2067 printf filehandle position, and added flag -w=0 to prevent issuing this
2068 error message. Suggested by Byron Jones.
2070 -Added modification to align a one-line 'if' block with similar
2071 following 'elsif' one-line blocks, like this:
2072 if ( $something eq "simple" ) { &handle_simple }
2073 elsif ( $something eq "hard" ) { &handle_hard }
2074 (Suggested by Wolfgang Weisselberg).
2077 -Eliminated all constants with leading underscores because perl 5.005_03
2078 does not support that. For example, _SPACES changed to XX_SPACES.
2079 Thanks to kromJx for this update.
2082 -the directory of test files has been moved to a separate distribution
2083 file because it is getting large but is of little interest to most users.
2084 For the current distribution:
2085 perltidy-20010701.tgz contains the source and docs for perltidy
2086 perltidy-20010701-test.tgz contains the test files
2088 -fixed bug where temporary file perltidy.TMPI was not being deleted
2089 when input was from stdin.
2091 -adjusted line break logic to not break after closing brace of an
2092 eval block (suggested by Boris Zentner).
2094 -added flag -gnu (--gnu-style) to give an approximation to the GNU
2095 style as sometimes applied to perl. The programming style in GNU
2096 'automake' was used as a guide in setting the parameters; these
2097 parameters will probably be adjusted over time.
2099 -an empty code block now has one space for emphasis:
2100 if ( $cmd eq "bg_untested" ) {} # old
2101 if ( $cmd eq "bg_untested" ) { } # new
2102 If this bothers anyone, we could create a parameter.
2104 -the -bt (--brace-tightness) parameter has been split into two
2105 parameters to give more control. -bt now applies only to non-BLOCK
2106 braces, while a new parameter -bbt (block-brace-tightness) applies to
2107 curly braces which contain code BLOCKS. The default value is -bbt=0.
2109 -added flag -icp (--indent-closing-paren) which leaves a statment
2110 termination of the form );, };, or ]; indented with the same
2111 indentation as the previous line. For example,
2113 @month_of_year = ( # default, or -nicp

2123 -Vertical alignment updated to synchronize with tokens &&, ||,
2124 and, or, if, unless. Allowable space before forcing
2125 resynchronization has been increased. (Suggested by Wolfgang
2128 -html corrected to use -nohtml-bold-xxxxxxx or -nhbx to negate bold,
2129 and likewise -nohtml-italic-xxxxxxx or -nhbi to negate italic. There
2130 was no way to negate these previously. html documentation updated and
2131 corrected. (Suggested by Wolfgang Weisselberg).
2133 -Some modifications have been made which improve the -lp formatting in
2136 -Perltidy now retains or creates a blank line after an =cut to keep
2137 podchecker happy (Suggested by Manfred H. Winter). This appears to be
2138 a glitch in podchecker, but it was annoying.
2141 -Added -bli flag to give continuation indentation to braces, like this
2145 extra_indentation();
2148 -Corrected an error with the tab (-t) option which caused the last line
2149 of a multi-line quote to receive a leading tab. This error was in
2150 version 2001 06 08 but not 2001 04 06. If you formatted a script
2151 with -t with this version, please check it by running once with the
2152 -chk flag and perltidy will scan for this possible error.
2154 -Corrected an invalid pattern (\R should have been just R), changed
2155 $^W =1 to BEGIN {$^W=1} to use warnings in compile phase, and corrected
2156 several unnecessary 'my' declarations. Many thanks to Wolfgang Weisselberg,
2157 2001-06-12, for catching these errors.
2159 -A '-bar' flag has been added to require braces to always be on the
2160 right, even for multi-line if and foreach statements. For example,
2161 the default formatting of a long if statement would be:
2163 if ($bigwasteofspace1 && $bigwasteofspace2
2164 || $bigwasteofspace3 && $bigwasteofspace4)
2169 With -bar, the formatting is:
2171 if ($bigwasteofspace1 && $bigwasteofspace2
2172 || $bigwasteofspace3 && $bigwasteofspace4) {
2175 Suggested by Eli Fidler 2001-06-11.
2177 -Uploaded perltidy to sourceforge cvs 2001-06-10.
2179 -An '-lp' flag (--line-up-parentheses) has been added which causes lists
2180 to be indented with extra indentation in the manner sometimes
2181 associated with emacs or the GNU suggestions. Thanks to Ian Stuart for
2182 this suggestion and for extensive help in testing it.
2184 -Subroutine call parameter lists are now formatted as other lists.
2185 This should improve formatting of tables being passed via subroutine
2186 calls. This will also cause full indentation ('-i=n, default n= 4) of
2187 continued parameter list lines rather than just the number of spaces
2188 given with -ci=n, default n=2.
2190 -Added support for hanging side comments. Perltidy identifies a hanging
2191 side comment as a comment immediately following a line with a side
2192 comment or another hanging side comment. This should work in most
2193 cases. It can be deactivated with --no-hanging-side-comments (-nhsc).
2194 The manual has been updated to discuss this. Suggested by Brad
2195 Eisenberg some time ago, and finally implemented.
2198 -fixed problem with parsing command parameters containing quoted
2199 strings in .perltidyrc files. (Reported by Roger Espel Llima 2001-06-07).
2201 -added two command line flags, --want-break-after and
2202 --want-break-before, which allow changing whether perltidy
2203 breaks lines before or after any operators. Please see the revised
2204 man pages for details.
2206 -added system-wide configuration file capability.
2207 If perltidy does not find a .perltidyrc command line file in
2208 the current directory, nor in the home directory, it now looks
2209 for '/usr/local/etc/perltidyrc' and then for '/etc/perltidyrc'.
2210 (Suggested by Roger Espel Llima 2001-05-31).
2212 -fixed problem in which spaces were trimmed from lines of a multi-line
2213 quote. (Reported by Roger Espel Llima 2001-05-30). This is an
2214 uncommon situation, but serious, because it could conceivably change
2215 the proper function of a script.
2217 -fixed problem in which a semicolon was incorrectly added within
2218 an anonymous hash. (Reported by A.C. Yardley, 2001-5-23).
2219 (You would know if this happened, because perl would give a syntax
2220 error for the resulting script).
2222 -fixed problem in which an incorrect error message was produced
2223 after a version number on a 'use' line, like this ( Reported
2224 by Andres Kroonmaa, 2001-5-14):
2226 use CGI 2.42 qw(fatalsToBrowser);
2228 Other than the extraneous error message, this bug was harmless.
2231 -fixed serious bug in which the last line of some multi-line quotes or
2232 patterns was given continuation indentation spaces. This may make
2233 a pattern incorrect unless it uses the /x modifier. To find
2234 instances of this error in scripts which have been formatted with
2235 earlier versions of perltidy, run with the -chk flag, which has
2236 been added for this purpose (SLH, 2001-04-05).
2238 ** So, please check previously formatted scripts by running with -chk
2241 -continuation indentation has been reprogrammed to be hierarchical,
2242 which improves deeply nested structures.
2244 -fixed problem with undefined value in list formatting (reported by Michael
2247 -Switched to graphical display of nesting in .LOG files. If an
2248 old format string was "(1 [0 {2", the new string is "{{(". This
2249 is easier to read and also shows the order of nesting.
2251 -added outdenting of cuddled paren structures, like ")->pack(".
2253 -added line break and outdenting of ')->' so that instead of
2256 -text => "perltidy",
2257 -relief => 'ridge')->pack;
2259 the current default is:
2262 -text => "perltidy",
2266 (requested by Michael Langner 2001-03-31; in the future this could
2267 be controlled by a command-line parameter).
2269 -revised list indentation logic, so that lists following an assignment
2270 operator get one full indentation level, rather than just continuation
2271 indentation. Also corrected some minor glitches in the continuation
2274 -Fixed problem with unwanted continuation indentation after a blank line
2275 (reported by Erik Thaysen 2001-03-28):
2277 -minor update to avoid stranding a single '(' on one line
2280 -corrected serious error tokenizing filehandles, in which a sub call
2281 after a print or printf, like this:
2282 print usage() and exit;
2284 print usage () and exit;
2285 Unfortunately, this converts 'usage' to a filehandle. To fix this, rerun
2286 perltidy; it will look for this situation and issue a warning.
2288 -fixed another cuddled-else formatting bug (Reported by Craig Bourne)
2290 -added several diagnostic --dump routines
2292 -added token-level whitespace controls (suggested by Hans Ecke)
2295 -added support for special variables of the form ${^WANT_BITS}
2297 -space added between scalar and left paren in 'for' and 'foreach' loops,
2298 (suggestion by Michael Cartmell):
2300 for $i( 1 .. 20 ) # old
2301 for $i ( 1 .. 20 ) # new
2303 -html now outputs cascading style sheets (thanks to suggestion from
2306 -flags -o and -st now work with -html
2308 -added missing -html documentation for comments (noted by Alex Izvorski)
2310 -support for VMS added (thanks to Michael Cartmell for code patches and
2313 -v-strings implemented (noted by Hans Ecke and Michael Cartmell; extensive
2314 testing by Michael Cartmell)
2316 -fixed problem where operand may be empty at line 3970
2317 (\b should be just b in lines 3970, 3973) (Thanks to Erik Thaysen,
2318 Keith Marshall for bug reports)
2320 -fixed -ce bug (cuddled else), where lines like '} else {' were indented
2321 (Thanks to Shawn Stepper and Rick Measham for reporting this)
2324 -fixed undefined value in line 153 (only worked with -I set)
2325 (Thanks to Mike Stok, Phantom of the Opcodes, Ian Ehrenwald, and others)
2327 -fixed undefined value in line 1069 (filehandle problem with perl versions <
2328 5.6) (Thanks to Yuri Leikind, Mike Stok, Michael Holve, Jeff Kolber)
2331 -Initial announcement at freshmeat.net; started Change Log
2332 (Unfortunately this version was DOA, but it was fixed the next day)
