Subject: [ruby-core:117494] [Ruby master Bug#20421] String#index and String#byteindex don't clear `$~` when offset > size (or bytesize)
Date: Thu, 11 Apr 2024 15:57:06 +0000 (UTC) [thread overview]
Message-ID: <redmine.issue-20421.20240411155705.13553@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-20421.20240411155705.13553@ruby-lang.org
Issue #20421 has been reported by andrykonchin (Andrew Konchin).
----------------------------------------
Bug #20421: String#index and String#byteindex don't clear `$~` when offset > size (or bytesize)
https://bugs.ruby-lang.org/issues/20421
* Author: andrykonchin (Andrew Konchin)
* Status: Open
* ruby -v: 3.2.2
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
When String#index and String#byteindex are called with Regexp and offset they clear `$~` (that contains result of the last Regexp matching) when offset < -size. But they don't clear `$~` when offset > size what seems not consistent:
```ruby
"a".index(/a/)
p $~ # => #<MatchData "a">
string = "blablabla"
string.index(/bla/, string.length + 1)
p $~ # => #<MatchData "a">
```
