From: "dgutov (Dmitry Gutov)" Date: 2012-09-06T09:33:10+09:00 Subject: [ruby-core:47441] [ruby-trunk - Bug #5024] ruby-mode.el syntax highlighting breaks on regular expression with quotes Issue #5024 has been updated by dgutov (Dmitry Gutov). This is kinda-fixed in the Emacs trunk, provided that "method" is one of the names in the list `ruby-syntax-methods-before-regexp`. Otherwise, the whole regexp literal isn't recognized in the first example. It should be obvious, the string-like highlighting would only start after the " character. ---------------------------------------- Bug #5024: ruby-mode.el syntax highlighting breaks on regular expression with quotes https://bugs.ruby-lang.org/issues/5024#change-29202 Author: slickrobert (Robert Smith) Status: Assigned Priority: Normal Assignee: nobu (Nobuyoshi Nakada) Category: Target version: 1.9.2 ruby -v: 1.9.2-p180 revision 30909 I am using 1.9.2-p160 revision 29036 If there are an odd number of quotation marks inside a regular expression, the syntax highlighting breaks, continuing the regular expression color until another quotation mark is found. method /^"([^"]*)"$/ do |arg| # continues regular expression syntax color until quotation is matched Syntax continues to work correctly with parentheses around the method, such as method(/^"([^"]*)"$/) do |arg| Searching led me to a related bug that was fixed: http://redmine.ruby-lang.org/issues/show/4242 -- http://bugs.ruby-lang.org/
