New submission from Dennis Malcorps <dennis.malco...@googlemail.com>:
Currently argparse has a 'version' action which can be triggered by user
defined options which prints out a custom string.
parser.add_argument("--version", action="version", version="test 1.2.3")
Since the 'version' action can be added multiple times, it can be used to
output different kinds of information, like the program's license.
parser.add_argument("--license", action="version", version="This file is
licensed under GPL.... [a huge amount of text]")
The only drawback is that linebreaks are substituted with a normal space. So I
propose a 'print' action (perhaps as a replacement for 'version'?) which
respects whitespace characters.
parser.add_argument("--version", action="print", message="test 1.2.3")
parser.add_argument("--license", action="print", message="This file is licensed
under GPL.... [a huge amount of text, now properly formatted!]")
parser.add_argument("--insult-me", action="print", message="You sick *peep* ,
*peep* yourself in *peep*")
Currently, the only solution is to create a custom action which is IMHO a bit
overkill for just printing a simple string to stdout.
