Changes for version 0.043 - 2015-11-18
- No changes since 0.042_05.
Changes for version 0.042_05 - 2015-11-11
- 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.
Changes for version 0.042_04 - 2015-11-10
- 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}'
Changes for version 0.042_03 - 2015-11-05
- 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.
Changes for version 0.042_02 - 2015-10-31
- 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.
Changes for version 0.042_01 - 2015-10-29
- 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.
