Does Ruby have a method similar to Emacs align-regexp?

Looking for a Ruby method to operate on an array of strings and align them according to a regex given as as an argument. Emacs has a defun called align-regexp that does this interactively when operating on a region of a buffer.

Here is a portion of the emacs doc string for align-regexp.

For example, let's say you had a list of phone numbers, and wanted to align them so that the opening parentheses would line up:

Fred [phone]Alice [phone]Mary-Anne [phone]Joe [phone]

There is no predefined rule to handle this, but you could easily do it using a REGEXP like "(". All you would have to do is to mark the region, call `align-regexp' and type in that regular expression. Here is the result:

Fred      [phone]Alice     [phone]Mary-Anne [phone]Joe       [phone]

lines = [  'Fred [phone]',  'Alice [phone]',  'Mary-Anne [phone]',  'Joe [phone]',]rows = lines.map { |line| line.partition('(') }pos = rows.map { |row| row[0].size }.maxputs rows.map { |row| row[0] = row[0].ljust(pos); row.join }
output:
Fred      [phone]Alice     [phone]Mary-Anne [phone]Joe       [phone]
