Assume I have the collowing perl code

x(a , b , c)
x(abc , boo_bar , THIS_IS_A_LONG_VARIABLE);

How do I get align-regexp to align on all three commas?

x(a     , b          ,
c                                             );
x(abc , boo_bar , THIS_IS_A_LONG_VARIABLE);

The easiest solution to your problem is to use 'align-all-strings'
from the 'align-string'-package instead of 'align-regexp'. If the
package isn't loaded by default a simple (require 'align-string)
should do the job.

On the other hand, if you need the full power of "align-regexp" you
can call it with C-u prefix to get all the options.

You could put the following simple command in your initfile

   (defun align-repeat (start end regexp)
   "repeatedly align using a regexp as the field separator.
   Works on the current region"
     (interactive "r\nsAlign regexp: ")
     (if (equal start end)
        (message "no region !"))
     (align-regexp start end 
          (concat "\\(\\s-*\\)" regexp) 1 align-default-spacing t))
   
Then select your text, and type M-x align-repeat RET , RET
