New submission from Jay T <jayt...@gmail.com>:
I want to create a custom interactive shell where I continually do
parse_args. Like the following:
parser = argparse.ArgumentParser()
command = raw_input()
while(True):
args = parser.parse_args(shlex.split(command))
# Do some magic stuff
command = raw_input()
The problem is that if I give it invalid input, it errors and exits
with a help message.
I learned from argparse-users group that you can override the exit method like
the following:
class MyParser(ArgumentParser):
def exit(self, status=0, message=None):
# do whatever you want here
I would be nice to have this usage documented perhaps along with best practices
for doing help messages in this scenario.
