Subject: [ruby-core:68675] [Ruby trunk - Bug #11014] [Open] String#partition doesn't return correct result on zero-width match
Date: Sun, 29 Mar 2015 14:51:57 +0000 [thread overview]
Message-ID: <redmine.issue-11014.20150329145156.83c85d356af35f8f@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-11014.20150329145156@ruby-lang.org
Issue #11014 has been reported by Janko Marohnić.
----------------------------------------
Bug #11014: String#partition doesn't return correct result on zero-width match
https://bugs.ruby-lang.org/issues/11014
* Author: Janko Marohnić
* Status: Open
* Priority: Normal
* Assignee:
* ruby -v: ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin14]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
First, to see how String#match works on my example:
~~~
match = "foo".match(/^=*/)
match.pre_match #=> ""
match[0] #=> ""
match.post_match #=> "foo"
~~~
Now, if I used String#partition instead of match, I'd expect to get `["", "", "foo"]` (pre_match, match, post_match). However
~~~
"foo".partition(/^=*/) #=> ["foo", "", ""]
~~~
String#rpartition returns the correct result (with the same regex).
