Justify Text (by UFO-Pu55y)

[Dave Brotherstone]

This script justifies the selected to the given width.  Written by UFO-Pu55y, posted here so people can find it.

'''
    Align text to  both  the  left
    and right margin of a  defined
    width,  adding   extra   space
    between words as necessary.

    Note: Only  makes  sense  when
    using    monospaced     fonts!

This looks really nice, but when I try to save the program to a text file (using either the clipboard or the File/Save menu of the browser), I get a single long line without breaks.  It looks as though the administrators of this forum have disabled attachments (I don't understand why they've done that).  Perhaps there is some other way of posting this that would circumvent this problem?

Thanks!

Either your browser isn't worth it, or the settings changed meanwhile. I had no problem with missing breaks.
