Get substring after the first = symbol in Ruby

Question

Purely out of curiosity, is there a more elegant way to simply get the substring after the first = symbol in a string? The following works to give back name=b

Answer 1

Use String#match

You can use a regular expression with positive lookbehind to find your match. For example:

string = "option=name=bob"
string.match /(?<==).*/
# => #

Use Match Variables to Access Result

Even if you haven't assigned the match data to a variable, Ruby will store it in special match variables for you.

$&
# => "name=bob"
