From: andrew@... Date: 2017-10-20T00:56:03+00:00 Subject: [ruby-core:83403] [Ruby trunk Feature#14022] String#surround Issue #14022 has been updated by avit (Andrew Vit). An alternate (short but cryptic) way: ``` str = "one\ntwo" str.gsub(/^.*/m, '<\0>') ``` - gsub! can do it destructively - using `/m` can control if it wraps each line, or all (A similar usage for wrapping characters in a string is shown in the String#gsub documentation) Out of curiosity, can someone explain why the `^` is needed in my regex? ---------------------------------------- Feature #14022: String#surround https://bugs.ruby-lang.org/issues/14022#change-67367 * Author: sawa (Tsuyoshi Sawada) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- After joining the elements of an array into a string using `Array#join`, I frequently need to put substrings before and after the string. In such case, I would have to use either of the following: ```ruby [1, 2, 3].join(", ").prepend("<").concat(">") # => "<1, 2, 3>" "<#{[1, 2, 3].join(", ")}>" # => "<1, 2, 3>" "<" + [1, 2, 3].join(", ") + ">" # => "<1, 2, 3>" ``` but none of them is concise enough. I wish there were `String#surround` that works like this: ```ruby [1, 2, 3].join(", ").surround("<", ">") # => "<1, 2, 3>" ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
