### Background Argh follows Argparse's grouping of arguments into two bunches: - "Positional" = determined by position and required (possibly optional with `nargs` set to `?` or `*`) - "Optional"...

### Example program ```python #!/usr/bin/python from time import sleep import argh def main(): for i in range(3): sleep(1) yield f'line {i}' argh.dispatch_command(main) ``` ### Case A: ``` $ ./app.py 0...

### Observation ``` $ timetra find -a sleep -f 'foooooooooooooooooooooooooooooooooooooooooooo' | head foooooooooooooooooooooooooooooooooooooooooooo foooooooooooooooooooooooooooooooooooooooooooo foooooooooooooooooooooooooooooooooooooooooooo foooooooooooooooooooooooooooooooooooooooooooo foooooooooooooooooooooooooooooooooooooooooooo foooooooooooooooooooooooooooooooooooooooooooo foooooooooooooooooooooooooooooooooooooooooooo foooooooooooooooooooooooooooooooooooooooooooo foooooooooooooooooooooooooooooooooooooooooooo foooooooooooooooooooooooooooooooooooooooooooo Traceback (most recent call last): File "/home/andy/src/timetra/bin/timetra", line...

Let's say we want to add a command to the parser with slightly different configuration: ``` python class Foo: def meth(self): pass foo = Foo() command = argh.named('another-name')(foo.meth) # WRONG!...

Typical case: ``` python class Controller: db = {1: 'foo', 2: 'bar'} def index(self): return self.db.keys() def detail(self, key): return self.db[key] c = Controller() # now parser.add_commands([c.index, c.detail]) # ideally...

Building the complete ArgumentParser tree in complex apps (with namespaced commands i.e. subparsers) can take considerable time (as it imports just about everything from the sub-apps). A "lazy" parsing tree...

Partial command names

..like in Mercurial: ``` #!bash $ hg sta $ hg status ``` This doesn't seem to be available in argparse in any form. **Note**: This issue has been automatically migrated...

Support more levels for nested commands

Currently "only" three levels are supported: prog, subparser and subsubparser. **Note**: This issue has been automatically migrated from Bitbucket Created by @neithere on 2010-11-13 00:34:12+00:00, last updated: 2012-12-18 15:34:21+00:00
