[issue9653] New default argparse output to be added
Steven Bethard steven.beth...@gmail.com added the comment: I see. When there are no arguments you basically want to replace the standard argparse help entirely with your own message, with your own capitalization, etc. What you're doing now looks like a pretty good approach for this, so I guess I'm still not clear what you're asking for. Could you suggest a concrete API for argparse that would make it easier to do what you want to do? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9653 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Of course that works, but I want to be able to customize the parser so
it shows something like:
Usage: program name [options]
Use option '-h' for help.
Two problems for me with current behavior:
1. usage and optional = not capitalized
2. usage: temp.py [-h] [--foo FOO] = gets very lengthy and mind
numbing for programs with lots of options

Steven Bethard steven.beth...@gmail.com added the comment:
Sorry, typo. Should have been len(sys.argv) == 1. Full script:
import argparse
import sys
parser = argparse.ArgumentParser()
parser.add_argument('--foo')
if len(sys.argv) == 1:
parser.print_help()
else:
print(parser.parse_args())
With that script, I see:
$ ./python.exe temp.py
usage: temp.py [-h] [--foo FOO]
optional arguments:
-h, --help show this help message and exit
--foo FOO

[issue9653] New default argparse output to be added
New submission from Tom Browder tom.brow...@gmail.com:
When I use the argparse module, and I enter my program name with NO arguments
or options, I would like the argparser to output something like:
Usage: program name [options]
Use option '-h' for help.
I haven't yet found how to do that in the argparse module source code, but I do
that now in my programs by adding this code near the beginning of the program:
# give rudimentary help if nothing but prog name is entered
import os
# get program name as it is called
pnam = os.path.basename(sys.argv[0])
Use = Usage: {0} [options].format(pnam)
if len(sys.argv) == 1:
print(Use)
print(Use option '-h' for help.)
sys.exit()
