[SOLVED] Reflowing comment blocks with vim

Reflowing comment blocks with vim

I'm cleaning up someone else's code and working with vim. I'd like to reflow the comments so that they're formatted consistently.

For example:

    # one two three four five six seven
    # eight nine
    # ten eleven twelve thirteen fourteen
    # fifteen sixteen seventeen 
    # eighteen
    # nineteen

Would become:

    # one two three four five six seven eight nine ten eleven 
    # twelve thirteen fourteen fifteen sixteen seventeen
    # eighteen nineteen

So, a workflow that would easily uncomment the code, reflow the paragraph and then re-comment the code with the indentation preserved. If there is an existing plugin which does exactly this, that would be great.

Solution

The gq command takes comments and indentation into account. I normally use V to visually select the lines (with k and j) and then press gq. The textwidth option is used to format the lines at the appropriate length. See :help gq for more information.
