- (args:width [default: 25])parameter
Width of the left (option) column. We don't automatically format this column based on the length of the longest option, but you can set its width manually.
The formatter maintains at least 2 spaces between the option keys and the option docstrings. If there is not enough space, the docstring will start on the next line. The 2 spaces of padding are included in args:width. The indent does not get counted in args:width. So the docstrings always begin at column args:indent + args:width.
