----------------------------------------
Bug #10891: /[[:punct:]]/ POSIX group broken (with string literals?)
https://bugs.ruby-lang.org/issues/10891#change-51615
* Author: Tom Lord
* Status: Open
* Priority: Normal
* Assignee: ruby-core
* ruby -v: ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-linux]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
The regular expression: `/[[:punct:]]/` should match the following characters:
! " # $ % & ' ( ) * + , - . / : ; < = > ? @ [ \ ] ^ _ ` { | } ~
However, it only works for these characters:
! " # % & ' ( ) * , - . / : ; ? @ [ \\ ] _ { }
And does not work for these characters:
$ + < = > ^ ` | ~
However, this is where it gets really weird... Consider the following:
60.chr == "<" # true
60.chr =~ /[[:punct:]]/ # => 0
"<" =~ /[[:punct:]]/ # => nil
So, it seems that the regular expression only fails for string literals!
