0.090_01 2025-09-27 T. R. Wyant Avoid "Possible attempt to escape whitespace" warning, which is emitted in perl-5.43.2 and forward. Thanks to James E. Keenan for the pull request. 0.090 2025-09-21 T. R. Wyant Explain s///eee... Perl commit 040a4d7 (perlop: properly document s///e modifier) by mauke, makes perlop explicitly state that more than 2 'e' modifiers are permitted, and cause the result of the expression to be eval-ed n-1 times, where n is the number of 'e' modifiers. Fix typo in comment. Thanks to Michal Josef Špaček for picking this up and providing the pull request. 0.089 2025-05-18 T. R. Wyant The /x modifier should not affect the parse of the replacement string in a substitution operator. That is, the '#' in s/x/#/x does NOT introdice a comment. Correct POD link in PPIx::Regexp::Token::Literal. Annotate sub class(), since with Perl 5.38 it is a built-in. 0.088 2023-02-28 T. R. Wyant Remove support for (**{ ... code ... }). This was introduced in Perl 5.37.8 along with a single-splat version. The double-splat version was removed without deprecation in Perl 5.37.9, so it is being removed without deprecation here as well, per my stated policy about development functionality. The single-splat version still exists (and is documented) in Perl 5.37.9, and in this package. 0.087 2023-01-28 T. R. Wyant Add support for code in optimized regex, a.k.a. (*{...}). This involved making the recognition of backtracking control more specific, since it also uses (?*...). If (*{...}) and (**{...}) are removed from Perl before Perl 5.38.0, support for them will be removed from this package. 0.086 2022-12-13 T. R. Wyant Add width(), which returns the number of characters matched. Note that an indefinite upper boumd is represented as IEEE 754 Inf if that appears to be supported; otherwise by a singleton object overloaded to allow stringification, numification, and numeric tests. Use width() to enhance the detection of variable-width look-behinds. Serious clean-up on accepts_perl() subsystem. 0.085 2022-04-16 T. R. Wyant Remove 'postderef' argument to PPIx::Regexp->new(). Postfix dereference is always recognized. 0.084 2022-04-02 T. R. Wyant Require PPI 1.238 for postfix deref support, and recode the postfix deref logic in terms of 1.238's functionality. Parse '@{[ ... ]}' as code, not interpolation. This is more in line with what it actually represents, and allows correct versioning of postfix dereferences. But is is an incompatible change. 0.083 2022-03-17 T. R. Wyant Correct and optimize the computation of logical column position (the one that takes account of tabs). 0.082 2021-11-29 T. R. Wyant Add --version to eg/predump, and document all options with double dashes. Silence 'uninitialized' warning generated by /(?<=.{35})/. Thanks to Brian Fraser for reporting this. Try to quell weird Win32 test failures which seem to occur only in tests where I am using 'use open' to put the standard handles into UTF-8 mode. The fix (I hope) is to do this to the Test::Harness handles at run time instead of to the standard handles at compile time. Add file CONTRIBUTING. 0.081 2021-10-22 T. R. Wyant Any use of the postderef argument is now fatal. Correct generation of 'provides' metadata. Thanks to Favio Poletti for blogging https://github.polettix.it/ETOOBUSY/2021/06/15/the-real-pause-workaround/, and ultimately to Joel Berger for the pointer to https://metacpan.org/pod/CPAN::Meta::Spec#no_index Add YAPE::Regex to SEE ALSO 0.080 2021-04-16 T. R. Wyant All uses of the postderef argument to new() now warn. 0.079 2021-03-26 T. R. Wyant Get prerequisites up to snuff, and add xt/author/prereq.t to ensure they stay that way. Add rt.cpan.org back to bug reporting methods. Long live RT! 0.078 2021-01-28 T. R. Wyant Allow CPAN to index Script_Run, Atomic_Script_Run, since they made it into a production release. Allow {,3} and { 0 , 3 } as quantifiers, requiring at least Perl 5.33.6. Previously these parsed as literals. This parse will be retracted if it does not make it into 5.34.0. 0.077 2021-01-14 T. R. Wyant Add Travis CI testing. Use GitHub as bug tracker. R.I.P. rt.cpan.org. 0.076 2020-11-28 T. R. Wyant Correct (I hope) detection of \K in nested assertions. Variable-length look-behind is version 5.029009. Look-behinds quantified longer than 255 characters are an error, and are made into unknown tokens or structures. I ended up refactoring the PPIx::Regexp::Token::GroupType class initialization for the latter two changes. 0.075 2020-10-08 T. R. Wyant Warn on first use of attribute 'postderef'. 0.074 2020-09-08 T. R. Wyant Remove PPIx::Regexp::StringTokenizer itself and all documentation referring to it or the 'parse' argument to PPIx::Regexp->new(). 0.073 2020-07-28 T. R. Wyant Remove prototypes from testing subroutines defined in t/*.t. 0.072 2020-05-20 T. R. Wyant Drop dependency on List::MoreUtils. Thanks to Graham Ollis (plicease) for bringing the issues with this module to my attention. 0.071 2020-03-28 T. R. Wyant Recognize wildcard Unicode names (Perl 5.31.10). Try to get correct line number in derived PPI. This is done by injecting "\n" as needed. The initial #line directive becomes "#line 2", but is suppressed if I need to generate line 1. Improve normalization of content for ppi(). This involves the un-bracketing of things like ${foo}. Deprecate new() argument postderef. At this stage it is only documented as deprecated. In the first release after October 1 2020 it will warn on the first use. Eventually it will be retracted, and postfix dereferences will always be recognized. This is the default behavior now. Add dump argument/option 'short' which, if true, causes leading 'PPIx::Regexp::' to be removed from class names. 0.070 2020-02-27 T. R. Wyant Add index_locations option to PPIx::Regexp->new(). This defaults to true if the regexp is specified as a PPI::Element object. The locations are consistent with the containing PPI::Document. Add methods location(), column_number(), line_number(), logical_filename(), logical_line_number(), and visual_column_number() to PPIx::Regexp::Element. All return undef if the locations could not be determined. Add method statement() to PPIx::Regexp::Element. This returns the PPI statement containing the regexp element, or nothing if none. Add method is_matcher() to PPIx::Regexp::Element. This classifies objects as to whether they actually match something in the target string. Possible returns are true (they do), false but defined (they do not) and undef (no clue). Add methods first_token() and last_token() to PPIx::Regexp::Node. Add methods next_token() and previous_token() to PPIx::Regexp::Element. 0.069 2020-02-07 T. R. Wyant The PPIx::Regexp->new() 'parse' option is now fatal. This selected either string or regex parse. I consider the string parse a failed experiment. This is the latest step in removing it in favor of the PPIx::QuoteLike package. 0.068 2020-01-21 T. R. Wyant Expose PPIx::Regexp::Util::is_ppi_regexp_element() explain() on [[=x=]] now calls it a Character Equivalence. It's still a PPIx::Regexp::Token::CharClass::POSIX::Unknown (and therefore an error), though. 0.067 2019-08-30 T. R. Wyant \K was retracted in Perl 5.31.3, but only inside look-around assertions. 0.066 2019-08-16 T. R. Wyant Fix broken POD, and add tests to ensure it remains fixed. 0.065 2019-05-25 T. R. Wyant Quash undef error in __is_ppi_regexp_element() when passed a PPI::Token::Regexp::Transliterate Support proper version for qr'\N{name}'. Until 5.29.10 this construction failed to parse because it did not interpolate. But PPIx::Regexp blithely ignored this detail. As of 5.29.10, something like m'\N{LATIN CAPITAL LETTER L}' matches identically to m'L'. So I implemented introduction as of that version. Have explain() recognize Unicode property wildcards. 0.064 2019-04-01 T. R. Wyant Empty \p{} should be an error. \x{} and \x{ non-hex } should be errors under "use re 'strict'" \o{} should be an error \o{ non-octal } should be an error under "use re 'strict'" Support wildcard Unicode property values. These were added in 5.29.9. Add eg/find-variable-length-lookarounds Add convenience method extract_regexps(). This is a static method on PPIx::Regexp that takes as its argument a PPI::Document and manufactures PPIx::Regexp objects out of anything that parses to a regexp of some sort. Don't run illegal character tests before Perl 5.18 unless we're author testing, because they are noisy. I think the issue is not the Perl version per se, but the version of Unicode; Perl5180delta says it shipped with Unicode 6.2. 0.063 2018-11-08 T. R. Wyant Silence weird-character parse tests and make them no longer author-only. Further deprecate 'parse' argument to new(). You now get a warning on each use. 0.062 2018-08-12 T. R. Wyant Remove tokenizer method prior(). This is the last step in its deprecation. 0.061 2018-07-09 T. R. Wyant Only standalone graphemes and non-characters allowed as delimiters starting with Perl 5.29.0. Non-ASCII delimiters started working in 5.8.3, so that is what perl_version_introduced() returns for them. Collateral with all this, accept word characters as delimiters, but only with at least one space between the operator and the expression -- that is, 'qr xyx' is OK, but 'qrxyx' is not. 0.060 2018-06-16 T. R. Wyant \N{} now parses as the unknown token, not NoOp, regardless of the setting of 'use re qw< strict >;'. \N{} became unconditionally fatal in 5.28.0 (5.27.1, actually). The policy when the parse changes is to use the most-modern parse. Hence this change. As a side effect of this, the unknown token's explain() method now returns something -- normally the associated error. Add method remove_insignificant(). If the invocant isa Node, this returns a clone of the invocant with non-significant elements removed. Otherwise it returns either the invocant or nothing. 0.059 2018-05-08 T. R. Wyant Install @CARP_NOT everywhere so that warnings and exceptions generated in the bowels of the system appear to come from the point where the system is entered. Further deprecate string (versus regexp) parsing. The first use of the 'parse' argument to new() will result in a warning. If the value of the argument is 'guess' or 'string', the warning refers to PPIx::QuoteLike. 0.058 2018-04-26 T. R. Wyant Prefer /[0-9]/ over /\d/ for numeric checks. The latter can match non-ASCII digits. Explain the negated POSIX character classes. Also tweak some of the asserted explanations -- mostly for readability and parallel construction with the negated explanations, but it turns out [[:digit:]] is NOT equivalent to [0-9]. 0.057 2018-04-17 T. R. Wyant Allow ->asserts( 'a*' ). This modification actually allows wild cards in asserts() on all match semantic modifiers, but it is probably only useful in the case of 'a*', because that is the only one that can be doubled. Explain grouping structure as 'Grouping', not 'Capture or grouping'. Caret modifier was not turning off /n. This was complicated by the fact that (?^) was introduced in 5.13.6, but (?n) was not introduced until 5.21.8. The solution was to include -n in the expansion of the caret if and only if /n had been seen in the scope of the caret. Recognize caret in /(?^)x/. Acknowledge Regexp::Parsertron in SEE ALSO 0.056 2018-03-07 T. R. Wyant Support removal of unescaped literal left curlys after left parens, which was deprecated in 5.27.8. No actual change in output yet, since deprecation is not tracked, but the perl_version_removed() logic is there. Add next_element() and kin. These are analogous to next_sibling() and kin, but will cross over from content proper into structure (beginning and end delimiters, etc) and vice versa. Correct requirements_for_perl() for impossible regular expression. It now returns '! $]' when the components of the regexp are valid, but none are valid under any specific version of Perl. It used to think all Perls were OK when this happened. Add the alpha_assertions introduced in 5.27.9. Handle 5.27.9's change from +script_run to *script_run, and support *sr as a synonym. 0.055 2018-02-08 T. R. Wyant Tokenizer method prior() is now fatal. This was documented as package-private, but as it WAS documented, I am putting it through a deprecation cycle anyway. Six months from now it will be removed. Add Script_Run classes as subclasses to their superclass docs. This was missed in the last update. 0.054 2018-01-29 T. R. Wyant Add support for (+script_run:...). This is an experimental feature added in Perl 5.27.8. It imposes on any matches it contains the additional restriction that everything matched has to belong to the same Unicode script. This support will be retracted if the functionality does not make it into Perl 5.28. Add method scontent(). This returns significant content only. That is, if called on the parse of '/ f u b a r /x', it returns '/fubar/x'. 0.053 2017-10-30 T. R. Wyant Recognize \px as Unicode char class. At least, when the x is C, L, M, N, P, S or Z. The 'parse' argument to new() is now deprecated. 0.052 2017-09-07 T. R. Wyant RT 122715: Clarify Node->find_parents() documentation. Thanks to Salvatore Bonaccorso for letting me know about this problem. Further deprecate tokenizer method prior() in favor of prior_significant_token(). Add requirements_for_perl(). This is analogous to the CPAN::Meta::Requirements method requirements_for_module(), though the output is formatted differently. Also put in the actual requirements for an un-escaped literal left curly after a constant, which was removed in 5.25.1 and reinstated in 5.27.1. Add accepts_perl(). This is analogous to CPAN::Meta::Requirements->accepts_module(). I decided that CPAN::Meta;:Requirements was overkill, but this may turn out to be the wrong decision, so I will be careful what I expose. Document behavior of perl_version_introduced() and perl_version_removed() when a feature is re-introduced after removal, or re-removed after re-introduction. \N{} (empty curlys) removed in 5.27.1. 0.051 2017-01-29 T. R. Wyant Support whitespace inside [] if /xx in effect. Starting with Perl 5.25.9, a space or tab appearing inside a bracketed character class is not significant if /xx is asserted. Further deprecate tokenizer method prior() Add 'provides' data to ExtUtils::MakeMaker output SOME unescaped litaral '{' removed in 5.025001. After '.', Unicode classes, and bracketed classes (including extended) they are still legal. Make /\b{/ an error Perl fails to parse the above, because once it sees the '\b{' it wants to find one of the extended boundary assertions (like \b{wb}), and declares an error when it does not. So we check for this and rebless the curly into an unknown token, not a literal. 0.050 2016-05-06 T. R. Wyant Parse bracketed substitution with embedded comment. This is something like s{foo}\n#{bar}\n{baz} which is equivalent to s/foo/baz/. PPI gets this wrong, and we're not smart enough to fix up the PPI parse, but if given this as text, we now parse it correctly. We now recognize postfix dereferences by default, since Perl does beginning with 5.24. In other words, default new() argument 'postderef' to true. Unterminated substitutions (i.e. 's//') should no longer cause an exception. Instead they parse as an unknown token. 0.049 2016-04-19 T. R. Wyant Robustify PPIx::Regexp->perl_version_removed() The problem here was that if the expression being parsed was sufficiently badly-formed, $self->delimiters() would be undef, throwing a warning. Correct dump of embedded modifiers (eg: (?i:...)) 0.048 2016-02-29 T. R. Wyant Add option 'strict', like 'use re "strict"' In the presence of strict(), I opted to set perl_version_introduced to the version of Perl where the construct became an error. Parse '\N{}' as no-op. The previous parse was a character class ('\N') followed by two literals ('{' and '}'). But perl5238delta said that it had been ignored up to that time. Starting with 5.23.8 it is an error if 'use re strict' is in effect. Quash 'NOT a POSIX class ...' warning under 5.23.8 Add Makefile targets authortest and testcover. 0.047 2016-01-29 T. R. Wyant Recognize \b{lb}, introduced in 5.23.7. If this is retracted before 5.24, it will be removed outright. 0.046 2016-01-08 T. R. Wyant Add GitHub repository to mmetadata. 0.045 2015-12-31 T. R. Wyant Deprecate tokenizer method prior() in favor of prior_significant_token(). This is not part of the public interface, so I suppose I could have just slam-dunked it, but ... Add ability to parse strings as well as regexes The new functionality is controlled by the new new() argument 'parse', whose permitted values are 'regex' (the default), 'string', or 'guess'. String parsing, and the 'string' and 'guess' values of 'parse', are experimental. 0.044 2015-12-08 T. R. Wyant Allow nesting of \Q with \U, \L, and \F The perlop docs say these nest with each other. Playing with Perl suggests that \U, \L and \F supersede each other, but thet they as a group nest with \Q in either order, so that if you specify \Q and one of the \U, \L, \F group you need two \Es to turn them all back off. Restrict recognition of back references in replacement strings to \number form, since Perl itself does not recognize \g{...} or \k{...} there. Recognize postfix dereference if desired. This is controlled by the Boolean argument 'postderef' passed to PPIx::Regexp->new(). The default is false, but will become true if postfix dereference becomes mainstream Perl 5. Add explain() and supporting methods main_structure() and in_regex_set(). The explain() method returns a brief explanation of what the element does. 0.043 2015-11-18 T. R. Wyant Do not end regex set prematurely on finding '])' The problem is that '])' can occur within an extended bracketed character class if it contains grouping parentheses and the last item in a group is a regular bracketed character class and there is no white space between the end of the character class and the end of the group. Record parse failure if switch condition is unknown The structure was being reblessed to PPIx::Regexp::Structure::Unknown, but the number of parse failures was not being incremented. Parse \U and friends as meta-characters inside \Q...\E This turns out to be what Perl itself does, as shown by $ perl -E 'say qr{\Q\Ufoo}' Clear error when lexer identifies unknown token. Those who peruse the changes in this release will see that a bunch of refactoring was done as part of this. Parse white space inside bracketed character classes inside extended bracketed character classes (whew!) as literals, except for the space character itself and the horizontal tab. This tracks the corresponding change in Perl 5.23.4. This will be reverted if the corresponding Perl change does not make it into 5.24.0. Beginning with version 0.035, PPIx::Regexp was incorrectly reporting the sense of modifiers when the same token both asserted and negated modifiers (e.g. '(?x-i:...)'). This release should correct the problem. Document policy when Perl changes in such a way that the proper parse for a regular expression changes. In this case the more modern parse is preferred. 0.042 2015-10-09 T. R. Wyant Report error rather than failing when parsing a string consisting wholly of white space. Group types were not being recognized if they contained the delimiter character for the regexp (e.g. in qr<(?\ the look-behind assertion was not recognized as such). Correct mis-parse of ' s///'. Leading white space is supposed to be acceptable, but the leading whitespace token caused PPIx::Regexp::Lexer not to recognize the substitution as such. Tokenizer was failing when the string to be parsed was so bad it was trying to return the whole thing as a single PPIx::Regexp::Token::Unknown. PPIx::Regexp::Dumper now displays a message if a structure is missing its end delimiter. RT 107331 Produce parse error in the presence of trailing cruft. Thanks to Klaus Rindfrey for catching this. The tokenizer now does a preliminary scan for delimiting brackets and modifiers. Anything after the modifiers except for white space is now made into a PPIx::Regexp::Token::Unknown, resulting in a parse failure being reported. The previous implementation simply assumed a valid expression, and in the case of the expression in the ticket blithely mismatched the delimiters and returned a parse without failures, but which was manifestly bogus. Tweak documentation in PPIx::Regexp. 0.041 2015-07-02 T. R. Wyant Report \C (match octet) as removed in 5.23.0. Accept non-ASCII whitespace under /x. The Whitespace object can be multiple characters; the perl_version_introduced() becomes '5.021001' if any of them is a code point above 127. The perl_version_removed() method now returns '5.021001' when called on a PPIx::Regexp object produced by parsing '?foo?' (match once without explicit 'm'). The object produced by parsing 'm?foo?' still returns the minimum Perl version. 0.040 2015-05-31 T. R. Wyant Do not parse unadorned parentheses as capture groups when /n is in effect. Instead, they are parsed as PPIx::Regexp::Structure. Named captures appear to be unaffected by /n. Made a verbose dump a little more so. Specifically, dump max_capture_group where relevant, and display dumped values a bit more informatively. Report /n (no captures) as having been added in 5.21.8. 0.039 2015-04-02 T. R. Wyant Recognize nested subscripts in interpolation. Thanks to Andy Lester for finding this, which actually manifested in Perl-Critic-Policy-Variables-ProhibitUnusedVarsStricter. The problem is that the actual heuristics for finding the end of an interpolation are undocumented, and I missed this rather-obvious case. Add \b{g} (= \b{gcb}) 0.038 2015-03-09 T. R. Wyant Make \b{foo} into an unknown token (and therefore an error. This applies to \b{anything}, where 'anything' is anything bur 'gcb', 'wb', or 'sb'. Handle the boundary assertions introduced in Perl 5.21.9: '\b{gcb}' (grapheme cluster boundary), '\b{wb}' (word boundary), '\b{sb}' (sentence boundary), and the corresponding '\B{...}' constructions. Similar-looking things like '\b{foo}' are not recognized as assertions, and end up being literals. This is less general than I usually make things, but was done against the possibility that (e.g.) '\b{foo}' might be introduced later, requiring perl_version_released() to return a different number. Any of these retracted prior to Perl 5.22.0 will simply be removed from PPIx::Regexp. 0.037 2014-11-12 T. R. Wyant Have PPIx::Regexp::Structure::RegexSet POD recognize that the Perl docs (specifically perlrecharclass) now call this construction Extended Bracketed Character Classes, not sets. Correctly mark the replacement portion of s///ee as code. Prior to this release it was parsed as though no /e were present. Make available the number of times a given modifier is asserted (except for the match semantics modifiers which get handled differently). See PPIx::Regexp::Token::Modifier->asserted() and PPIx::Regexp::Tokenizer->modifier() for details. 0.036 2014-01-04 T. R. Wyant Retract the "Allow non-ASCII white space under /x" change introduced in version 0.033. I misread perl5170delta, and implemented early. Change to explicit character class to recognize white space under /x. I was previously using \s, which matched too much. Thanks to Nobuo Kumagai for finding and reporting this. 0.035 2013-11-15 T. R. Wyant Properly handle multi-character modifiers like /ee. We now handle /eie as being the same as /eei. Thanks to Anonymous Monk for finding this. Properly handle \g and \k back references that do not correspond to an actual capture group. They are now reblessed into the unknown token, and counted as errors. Thanks to Anonymous Monk for finding this. Add method error() to PPIx::Regexp::Element. This should return an error message when the element is in error -- normally when it has been blessed into the unknown token or structure. Add method modifier_asserted() to PPIx::Regexp::Element. This walks the parse tree backward to determine if the given modifier is in effect for the element. 0.034 2013-05-11 T. R. Wyant Correct spelling and grammar errors in POD and comments. RT #85050. Thanks David Steinbrunner for catching these. Allow interpolation in regex sets. It implies Perl 5.17.9 or higher. Allow non-ASCII white space under /x. It implies Perl 5.17.9 or higher. Fix problems with Regex Set functionality under Perl 5.6.2. CPAN testers RULE! 0.031 2013-01-31 T. R. Wyant Have PPIx::Regexp::Token::Code (and offspring) become PPIx::Regexp::Token::Unknown inside a regex set. 0.030 2013-01-22 T. R. Wyant Add Regex Sets, which were added to Perl as an experimental feature in 5.17.8. This is experimental in Perl, therefore the parse may change. Ditch PPIx::Regexp::Token::GroupType method __expect_after_match() in favor of the more general __match_setup(). This is done without deprecation because __expect_after_match() was documeted as package-private, but noted in the change log because it _was_ documented. 0.029 2013-01-14 T. R. Wyant Add method unescaped_content() to PPIx::Regexp::Element(). Rewrite the tokenizing code in PPIx::Regexp::Token::GroupType and offspring to use regular expressions specific to the regexp delimiter, and escaping only that delimiter. Thanks again to Alexandr Ciornii for finding more of these. Fix mis-parse of /(\?|I)/ as a branch reset (it's really an alternation). There may be more of these lurking. Thanks to Alexandr Ciornii for finding this one. Add options -files and -objectify to eg/predump. 0.028 2012-06-06 T. R. Wyant Replace all uses of YAML::Any with YAML, since they come in the same distro, and YAML does not suffer from deprecation warnings. 0.027 2012-05-28 T. R. Wyant Eliminate unescaped literal "{" characters in regexps in PPIx::Regexp::Token::Backreference and PPIx::Regexp::Token::CharClass::Simple. These are deprecated in 5.17.0. 0.026 2012-02-24 T. R. Wyant Add support for \F (fold case), added in 5.15.8. 0.025 2012-01-04 T. R. Wyant Tolerate leading and trailing white space around the regular expression. These are still round-trip safe, since the white space is tokenized. Make Changes file conform to CPAN::Changes, and add xt/author/changes.t to ensure continued compliance. 0.024 2011-12-17 T. R. Wyant Reinstate author test xt/author/manifest.t, which was clobbered shortly before the release of 0.021_10. 0.023 2011-12-08 T. R. Wyant Correct address of FSF in the version of the GPL distributed in LICENSES/Copying. Thanks to Petr Pisar for picking this up. 0.022 2011-11-24 T. R. Wyant Correct various documentation errors. Don't initialize effective modifiers with '^', since that wrongly asserts that /d has been seen somewhere along the line. Implement negation of match-semantic modifiers (e.g. 'no re /u;') by setting the relevant datum to undef. Support for default modifiers. This includes: * default_modifiers argument to new() in PPIx::Regexp, PPIx::Regexp::Tokenizer, and PPIx::Regexp::Dumper * Public method modifier_asserted() on PPIx::Regexp, to return whether a given modifier is actually in effect. The results of the modifier() method are unchanged. Require Test::More 0.88 for installation. Eliminate all the 'eval { require ... }' logic in favor of 'use Test::More 0.88'. Have Makefile.PL make use of {BUILD_REQUIRES} if it is available. Fix PPIx::Regexp::Token::Whitespace->can_be_quantified() to return false. 0.021 2011-07-22 T. R. Wyant Modified tokenizer to correctly handle a back slash used as a delimiter. I believe. PPIx::Regexp::Dumper now dumps the results of ppi() if that method is present and -verbose is asserted. 0.020 2011-04-02 T. R. Wyant Corrected perl_version_introduced(): * \R is now 5.009005 (was 5.000). 0.019 2011-03-01 T. R. Wyant Various corrections to perl_version_introduced(): * \X is now 5.006 (was 5.000); * \N{name} is now 5.006001 (was 5.006); * \N{U+xxxx} is now 5.008 (was 5.006). The \C is now parsed as a PPIx::Regexp::Token::CharClass::Simple. It was previously considered a PPIx::Regexp::Token::Literal. Ensure that \N{$foo} parses as a Unicode literal, not a quantified \N. The ordinal() method returns undef for this. Understand the /aa modifier, introduced with 5.13.10. Report perl_version_introduced() of 5.013010 for the new semantic modifiers when modifying the entire expression. Correct handling of interpolations like ${^foo} and $#{foo}. 0.018 2011-02-16 T. R. Wyant Override ppi() in PPIx::Regexp::Token::Interpolation to provide the proper PPI when variable names are bracketed. Properly parse bracketed variable names (I hope!), which may not be subscripted. Take account of possible '$' or '@' casts before a symbol in an interpolation (e.g. $$foo{bar}, which is equivalent to $foo->{bar}). Add the /a modifier to PPI::Regexp::Token::Modifiers, legal only in the (?:...) construction. This was introduced in Perl 5.13.9. When parsing an interpolation from a replacement string (rather than a regular expression), take subscripts at face value rather than trying to disambiguate them from quantifiers and character classes, which they can't be in this context. 0.016 2011-01-05 T. R. Wyant The PPIx::Regexp::Token::Code perl_version_introduced() method now returns the minimum Perl version (currently set to 5.000) if it is used to represent the substitution portion of s///e. 0.015 2010-10-25 T. R. Wyant Documented intent to revoke support for features introduced in a development Perl which do not make it to a production release. This is necessary because in this case the syntax could be reused with different semantics. Added support for Perl 5.13.6 (?^...) construction. Added support for Perl 5.13.6 d, l, and u modifiers. Fixed inconsistency in perl_version_introduced() results between PPIx::Regexp::Token::Modifier and PPIx::Regexp::Token::GroupType::Modifier. Corrected PPIx::Regexp::Constant RE_CAPTURE_NAME docs, somehow missed back at 0.010_01. 0.014 2010-10-14 T. R. Wyant Recognize \o{...} as a PPIx::Regexp::Token::Literal, with perl_version_introduced() of 5.0013003. Terminate \0.. through \7.. after three characters, as Perl does. These two were brought to my attention by Brian D. Foy's "The Effective Perler" for October 11 2010, http://www.effectiveperlprogramming.com/blog/697 Correct the PPIx::Regexp::Token::Literal ordinal() method for '\b'. As a literal, this is a back space. 0.013 2010-10-10 T. R. Wyant Declare a parse failure if characters are found between the '}' and the ')' of (?{...}) and (??{...}), and rebless the tokens to ::Unknown. Perl does not accept anything here, so I think I should not either. Whitespace tweak in the PPIx::Regexp::Dumper test output for the failures test. Replace the PPI logic in PPIx::Regexp::Token::Code with a call to $tokenizer->find_matching_delimiter(). This is actually the way Perl works, as a look at toke.c and regcomp.c makes clear. Push the perl_version_introduced() back to 5.0 at the request of Alexandr Ciornii, for the potential benefit of Perl::MinimumVersion. This was done mostly by reading the various perlre, perldelta, and perlop documents, so these should be taken with a HUGE grain of salt. 0.012 2010-09-26 T. R. Wyant Track all the features reported as introduced (or removed) in Perl 5.010 back to Perl 5.009005, and report them as such. Report modifier /r as having been introduced in Perl 5.013002, rather than the default of 5.006. 0.011 2010-09-16 T. R. Wyant Remove dependencies on Params::Util and Readonly. The latter was requested by ADAMK for the benefit of Padre. It involved changing the symbols exported from PPIx::Regexp::Constant, but these were documented as private, so ... Parse POSIX character classes [=a=] and [.a.] as PPIx::Regexp::Token::CharClass::POSIX::Unknown, which counts as a parse failure since these are not supported by Perl. Make the PPI::Document created by PPIx::Regexp::Token::Code->ppi() be read only. This means we need PPI 1.116. Cache the document, and ensure the cached result is returned on subsequent calls. 0.010 2010-08-06 T. R. Wyant Fix fatal error in PPIx::Regexp::Token::Code->ppi(). Move author tests from xt/ to xt/author/. 0.009 2010-08-03 T. R. Wyant Recognize s/.../.../ee as being different from s/.../.../e. In particular, the replacement portion of the former is _not_ a Perl expression: it's an interpolatble string, which later gets eval{}'ed. 0.008 2010-07-01 T. R. Wyant Promote methods can_be_quantified() and is_quantifier() from PPIx::Regexp::Token to PPIx::Regexp::Element, so all classes inherit them. They still return true and false respectively. Override can_be_quantified() to return false on PPIx::Regexp, PPIx::Regexp::Structure::Quantifier, PPIx::Regexp::Structure::Regexp, and PPIx::Regexp::Structure::Replacement. Override is_quantifier() to return true on PPIx::Regexp::Structure::Quantifier. Modify PPIx::Regexp::Dumper to be able to display can_be_quantified and is_quantifier for PPIx::Regexp::Node objects when dumping verbosely. Convert internal data to Readonly in PPIx::Regexp::Lexer, PPIx::Regexp::Token::CharClass::Simple, PPIx::Regexp::Token::Structure, and PPIx::Regexp::Tokenizer. Remove leftover boilerplate in PPIx::Regexp::Token::CharClass::Simple. Explicitly require a minimum Perl of 5.006. Centralized dependencies in inc/PPIx/Regexp/Meta.pm. Removed claim that PPIx::Regexp is alpha code. Docs still say that the interface can be changed, but now it will go through a deprecation cycle. 0.007 2010-04-28 T. R. Wyant PPIx::Regexp::Lexer no longer fails when encountering expressions like m{)}. Instead, it marks the right parenthesis as an unmatched delimiter. Fixed RT 56864 - PPIx::Regexp::Lexer fails in Perl::Critic under Perl 5.13.0. This was due to the value of a returned $+[0] getting transmogrified before the caller saw it. I never did isolate what triggered the bug. You can now get a tokenizer trace by setting environment value PPIX_REGEXP_TOKENIZER_TRACE to a non-zero numeric value. This is unsupported, though. 0.006 2010-02-26 T. R. Wyant Parse \N{...} in accordance with perl5115delta. The curlys must contain an alpha followed by alphanumerics, spaces, parens, colons, or dashes. \N{ without a matching } is a character class (if legal) followed by a literal '{'. Parse \N inside a character class as PPI::Regexp::Token::Unknown, since Perl 5.11.5 considers this a compile error. A \N{...} inside a character class is still OK. Add method match() to PPIx::Regexp::Tokenizer. This is analogous to capture(), but returns the entire matched string. 0.005 2009-12-26 T. R. Wyant Recognize \N (without curlys), back-ported from Perl 6 into 5.11. Recognize unicode characters as \N{[[:alpha:]] ... rather than \N{[\w\s:] ... This is per the 5.11 documentation, but I think Perl always worked this way. Recognize loose matching of Unicode character classes, and allow '=' in lieu of a single ':' in a Unicode character class (this from Perl 5.11.3). PPIx::Regexp::Dumper now produces the proper output when called with perl_version => 1, test => 1. Describe the typical content of the object in the documentation for PPIx::Regexp::Structure::NamedCapture and PPIx::Regexp::Token::GroupType::NamedCapture. 0.004 2009-11-09 T. R. Wyant Have PPIx::Regexp::Token::Literal correctly recognize when charnames::vianame() is unavailable, and decouple this from the handling of \N{U+hhhh}. Add dependency on Task::Weaken, since depending on Scalar::Util appears not to cut it. Correct the assignment of the license type in Makefile.PL. 0.003 2009-11-05 T. R. Wyant Have PPIx::Regexp::Token::Literal recognize \N{U+hhhh} (where hhhh represents hex digits), and provide its ordinal (hhhh). Remove recognition of \N. (. = any character), which Perl does not do. Fix $re->flush_cache() so that it actually removes $re and only $re from the cache. Add delimiters() method to PPIx::Regexp::Main and PPIx::Regexp. Support this in eg/prenav. Increase test coverage and remove dead code. Count tests in t/parse.t and t/unit.t 0.002 2009-10-28 T. R. Wyant In verbose mode, have PPIx::Regexp::Dumper dump the absolute capture number referred to by a numbered reference. Have eg/preslurp pass its -verbose option to PPIx::Regexp::Dumper Don't use Test::More::isa_ok for the t/basic.t class heritage tests, since some versions of Test::More require a reference for the first argument of isa_ok(). 0.001 2009-10-21 T.
