| | | | | | | | According to the C99 specification section 7.20.3.2 paragraph 2: > If ptr is a null pointer, no action occurs. So we do not need to check that the pointer is a null pointer.

* Regexp supports Unicoe 9.0.0's \Xnaruse2016-11-301-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | * meta character \X matches Unicode 9.0.0 characters with some workarounds for UTR #51 Unicode Emoji, Version 4.0 emoji zwj sequences. [Feature #12831] [ruby-core:77586] The term "character" can have many meanings bytes, codepoints, combined characters, and so on. "grapheme cluster" is highest one of such words, which means user-perceived characters. Unicode Standard Annex #29 UNICODE TEXT SEGMENTATION specifies how to handle grapheme clusters (extended grapheme cluster). But some specs aren't updated to current situation because Unicode Emoji is rapidly extended without well definition. It breaks the precondition of UTR#29 "Grapheme cluster boundaries can be easily tested by looking at immediately adjacent characters". (the sentence will be removed in the next version) Though some of its detail are described in Unicode Technical Report #51 UNICODE EMOJI but it is not merged into UTR#29 yet. http://unicode.org/reports/tr29/ http://unicode.org/reports/tr51/ http://unicode.org/Public/emoji/4.0/ git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@56949 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | Ruby's Regexp doesn't allow normal numbered groups if the regexp has named groups. On such case it optimizes out related NT_ENCLOSE. But even on the case it can use \g<0>. This fix not to remove NT_ENCLOSE whose regnum is 0. [ruby-core:75828] [Bug #12454] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@55562 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
