Date: Wed, 09 Dec 2015 05:33:58 +0000 [thread overview]
Message-ID: <redmine.journal-55387.20151209053358.ff5c5dda9535d96c@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-11793.20151209053122@ruby-lang.org
Issue #11793 has been updated by William Burnson.
Description updated
----------------------------------------
Bug #11793: puts 'ab'.gsub('a', '\\+') - unexpected output
https://bugs.ruby-lang.org/issues/11793#change-55387
* Author: William Burnson
* Status: Open
* Priority: Normal
* Assignee:
* ruby -v: ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-darwin15]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
Test case:
puts 'ab'.gsub('a', '\\\\+')
Expected output:
\\+b
Actual output:
b
The way I understand gsub(pattern, replacement) when used with two string arguments is that it will perform a literal replacement, so it is quite unexpected that substituting with \+ removes the pattern entirely.
