Subject: [ruby-core:111193] [Ruby master Feature#19177] optional offset for Array#index
Date: Sun, 04 Dec 2022 00:26:39 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-100477.20221204002638.11019@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-19177.20221203165050.11019@ruby-lang.org
Issue #19177 has been updated by Dan0042 (Daniel DeLorme).
Oops, duplicate of #17056, which has a PR and was accepted but... never merged?
----------------------------------------
Feature #19177: optional offset for Array#index
https://bugs.ruby-lang.org/issues/19177#change-100477
* Author: Dan0042 (Daniel DeLorme)
* Status: Open
* Priority: Normal
----------------------------------------
String#index allows an optional offset:
```ruby
"the quick brown fox jumps over the lazy dog".index("the") #=> 0
"the quick brown fox jumps over the lazy dog".index("the",1) #=> 31
```
I was a bit surprised that Array doesn't support this and I feel it would be a very natural addition:
```ruby
%w[the quick brown fox jumps over the lazy dog].index("the") #=> 0
%w[the quick brown fox jumps over the lazy dog].index("the",1) #=> 6 instead of ArgumentError
```
