Bug #5126

Unicode character classes interpolated into regex throws exception

ruby 1.9.3dev (2011-07-31 revision 32789) [x86_64-darwin10.7.0]
Backport:
[ruby-core:38635]

Description

The following script runs under 1.9.2-p290:

# encoding: UTF-8
letter = '\p{L}'
atext = "[#{letter}]"
/#{atext}/

Under 1.9.3-preview1 it raises an exception:

test.rb:6:in `<main>': invalid character property name {L}: /[\p{L}]/ (RegexpError)

The interpolation is necessary to reproduce this bug, unicode character classes work fine when entered directly into the regex.

JRuby has a similar bug: http://jira.codehaus.org/browse/JRUBY-5622

This technique is used in datamapper to build a regex for matching emails:
