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

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

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

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.

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.

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

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.

Prefer /[0-9]/ over /\d/ for numeric checks. The latter can match

Allow ->asserts( 'a*' ). This modification actually allows wild

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.

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.

which was removed in 5.25.1 and reinstated in 5.27.1.
Add accepts_perl(). This is analogous to

CPAN::Meta;:Requirements was overkill, but this may turn out to be
the wrong decision, so I will be careful what I expose.

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.

Add option 'strict', like 'use re "strict"'
In the presence of strict(), I opted to set perl_version_introduced

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.

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<(?\<foo)> 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.

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.

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.

Ditch PPIx::Regexp::Token::GroupType method __expect_after_match() in

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.

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.

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.

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.

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/.

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.

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.

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().
