Get string between two strings

/ Published in: Ruby

If you're using Rails and want to make this a global function, drop this into your application_controller and call it as a function.

Example:
# get_string_between("hellomyfriendmoto", 'o', 'm')
# > myfriend

Expand | Embed | Plain Text

Copy this code and paste it in your HTML

def get_string_between(my_string, start_at, end_at)
    my_string = " #{my_string}"
    ini = my_string.index(start_at)
    return my_string if ini == 0
    ini += start_at.length
    length = my_string.index(end_at, ini).to_i - ini
    my_string[ini,length]
end
