fill-paragraph in programming

Question

Is it possible, or does some function exists, to get the equivalent of the alt-q command, but in programming?

Suppose I've just written this in python:

group_parser.add_argument('-n',nargs=1, default=5,
help='specifies how many missing entries in a row are allowed before the whole row gets omitted.')

The following is a rather long line. Is it possible to have some sort of automation for getting the following output?

parser.add_argument('-n',nargs=1, default=5, 
                    help='specifies how many ' +
                    'missing entries in a row ' +
                    'are allowed before the whole row gets ' +
                    'omitted.')

In other words, a function that detects long input strings, and splits them up across multiple lines.

Answer 1

You should try multi-line. Out of the box it works sanely for many languages. You can cycle through many different indentation strategies.
