From: shevegen@... Date: 2018-05-24T13:18:49+00:00 Subject: [ruby-core:87252] [Ruby trunk Feature#14783] String#chars_at / String#bytes_at Issue #14783 has been updated by shevegen (Robert A. Heiler). Is the frequency of #bytes_at common? I understand the use case stated by Stefan (extract multiple indices via one method call on a String) but #bytes_at may seem to be quite rare. As for returning a String or Array, I personally expect #chars on a String object to return an Array, so intuitively I would assume #chars_at to also return an Array. ---------------------------------------- Feature #14783: String#chars_at / String#bytes_at https://bugs.ruby-lang.org/issues/14783#change-72242 * Author: sos4nt (Stefan Sch����ler) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- I just wanted to extract characters at certain indices from a string and noticed that there's no `values_at` counterpart for `String`. I'd therefore like to propose two new `String` methods: * `chars_at(selector, ...) ��� new_str` * `bytes_at(selector, ...) ��� new_str` which work basically like [`Array#values_at`](http://ruby-doc.org/core/Array.html#method-i-values_at), e.g.: ```ruby string = 'hello, world!' string.chars_at(0, 5, 7, 12) #=> "h,w!" string.chars_at(0..4, 7..11) #=> "helloworld" ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
