Revision history for Perl extension Text::Balanced.
|
|
|
|
1.00 Mon Aug 11 12:42:56 1997
|
|
|
|
- original version
|
|
|
|
|
|
1.01 Mon Sep 8 18:09:18 EST 1997
|
|
|
|
- changed "quotemeta" to "quotemeta $_" to work
|
|
around bug in Perl 5.002 and 5.003
|
|
|
|
|
|
1.10 Tue Sep 30 17:23:23 EST 1997
|
|
|
|
- reworked extract_quotelike to correct handling of some obscure cases
|
|
|
|
|
|
1.21 Sat Oct 4 17:21:54 EST 1997
|
|
|
|
- synchronised with Parse::RecDescent distribution (version number
|
|
will now reflect that package)
|
|
|
|
1.23 Fri Oct 17 10:26:38 EST 1997
|
|
|
|
- changed behaviour in scalar and void contexts. Scalar contexts
|
|
now return only the extracted string. Void contexts now remove
|
|
the extracted string from the first argument (or $_).
|
|
|
|
1.24
|
|
|
|
- changed behaviour in scalar contexts. Scalar contexts
|
|
now return the extracted string _and_ remove it from the
|
|
first argument (or $_).
|
|
|
|
- changed return values on failure (all contexts return undef
|
|
for invalid return fields)
|
|
|
|
- fixed some lurking bugs with trailing modifier handling
|
|
|
|
- added :ALL tag to simplify wholesale importing of functions
|
|
|
|
- fixed serious bug with embedded division operators ("/")
|
|
This now also allows the ?...? form of pattern matching!
|
|
|
|
1.35 Wed Jun 24 09:53:31 1998
|
|
|
|
- fixed handling of :: quantifiers in extract_variable()
|
|
|
|
- numerous trivial lexical changes to make xemacs happy
|
|
|
|
|
|
1.36 Tue Jul 14 12:26:04 1998
|
|
|
|
- Reinstated POD file missing from previous distribution
|
|
|
|
- Added undocumented fourth parameter to extract_codeblock
|
|
so as to correctly handle (?) and (s?) modifiers in
|
|
RecDescent grammars.
|
|
|
|
|
|
1.40 Tue Aug 4 13:54:52 1998
|
|
|
|
- Added (optional) handling of embedded quoted text to
|
|
extract_delimited (see revised entry in Balanced.pod)
|
|
|
|
- Added extract_tagged which extracts text between arbitrary,
|
|
optionally nested start and end tags (see new entry in
|
|
Balanced.pod).
|
|
|
|
- Added delimited_pat which builds a pattern which matches a
|
|
string delimited by any of the delimiters specified (see new
|
|
entry in Balanced.pod).
|
|
|
|
- Added test.pl
|
|
|
|
|
|
1.41 Mon Aug 10 14:51:50 1998
|
|
|
|
- Reinstated change to extract_codeblock from 1.36 which were
|
|
mysteriously lost in 1.40
|
|
|
|
|
|
1.50 Thu Aug 27 09:20:19 1998
|
|
|
|
- Improved the structure of the regex generated by
|
|
delimited_pat (and used in extract_delimited). It's
|
|
considerably more complex, but also more robust and
|
|
much faster in the worst case.
|
|
|
|
- Altered extract_variable to accept whitespace in variables,
|
|
e.g. '$ a -> {'b'} -> [2]'
|
|
|
|
|
|
|
|
1.51 Sat Feb 13 10:31:55 1999
|
|
|
|
- Fixed bugs in prefix matching in extract_variable:
|
|
* incorrectly used default if '' specified
|
|
* now handles $#array correctly
|
|
|
|
- Fixed bugs in extract_codeblock:
|
|
* Now handles !~ properly
|
|
* Now handles embedded comments better.
|
|
* Now handles "raw" pattern matches better.
|
|
|
|
- Added support for single strings or qr's as
|
|
'reject' and 'ignore' args to extract_tagged()
|
|
|
|
- Added gen_extract_tagged() to "precompile"
|
|
a specific tag extractor for repeated use
|
|
(approximately 3 times faster!)
|
|
|
|
|
|
1.52 Thu Mar 4 12:43:38 1999
|
|
|
|
- Added CSV parsing example to documentation of extract_multiple.
|
|
|
|
- Fixed a bug with extract_codeblock in "RecDescent" mode
|
|
(it would accept "subrule(s?)" and "subrule(?)", but
|
|
not "subrule(s)"). Thanks, Jan.
|
|
|
|
|
|
1.66 Fri Jul 2 13:29:22 1999
|
|
|
|
- Added ability to use quotelike operators in extract_bracketed
|
|
|
|
- Fixed bug under 5.003 ('foreach my $func' not understood)
|
|
|
|
- Added escape specification as fourth arg to &extract_delimited
|
|
|
|
- Fixed handling of &delimited_pat and &extract_delimited
|
|
when delimiter is same as escape
|
|
|
|
- Fixed handling of ->, =>, and >> in &extract_code
|
|
when delimiters are "<>"
|
|
|
|
|
|
1.76 Fri Nov 19 06:51:54 1999
|
|
|
|
- IMPORTANT: Now requires 5.005 or better.
|
|
|
|
- IMPORTANT: Made extract methods sensitive to the pos()
|
|
value of the text they are parsing. In other words,
|
|
all extract subroutines now act like patterns of the form
|
|
/\G.../gc. See documentation for details.
|
|
|
|
- IMPORTANT: Changed semantics of extract_multiple, in line
|
|
with the above change, and to simplify the semantics to
|
|
something vaguely predictable. See documentation for details.
|
|
|
|
- Added ability to use qr/../'s and raw strings as extractors
|
|
in extract_multiple. See documentation.
|
|
|
|
- Added fourth argument to extract_codeblock to allow
|
|
outermost brackets to be separately specified. See
|
|
documentation for details.
|
|
|
|
- Reimplemented internals of all extraction subroutines
|
|
for significant speed-ups (between 100% and 2000%
|
|
improvement).
|
|
|
|
- Fixed nasty bug in extract_variable and extract_codeblock
|
|
(they were returning prefix as well in scalar context)
|
|
|
|
- Allowed read-only strings to be used as arguments in
|
|
scalar contexts.
|
|
|
|
- Renamed delimited_pat to gen-delimited pat (in line with
|
|
gen_extract_tagged). Old name still works, but is now deprecated.
|
|
|
|
- Tweaked all extraction subs so they correctly handle
|
|
zero-length prefix matches after another zero-length match.
|
|
|
|
|
|
1.77 Mon Nov 22 06:08:23 1999
|
|
|
|
- Fixed major bug in extract_codeblock (would not
|
|
terminate if there was trailing whitespace)
|
|
|
|
- Improved /.../ pattern parsing within codeblocks
|
|
|
|
|
|
1.81 Wed Sep 13 11:58:49 2000
|
|
|
|
- Fixed test count in extract_codeblock.t

|
|
|
|
- Added handling of globs and sub refs to extract_variable
|
|
|
|
- Pod tweak (thanks Abigail)
|
|
|
|
- Allowed right tags to be run-time evaluated, so
|
|
extract_tagged($text, '/([a-z]+)', '/end$1') works
|
|
as expected.
|
|
|
|
- Added optional blessing of matches via extract_multiple
|
|
|
|
- Fixed bug in autogeneration of closing tags in extract_tagged
|
|
(Thanks, Coke)
|
|
|
|
- Fixed bug in interaction between extract_multiple and
|
|
gen_extract_tagged (Thanks Anthony)

1.86 Mon Sep 3 06:57:08 2001
|
