Push function name and meta of sub-command into function

[TomFreudenberg]

Hi, I wanted to re-use especially the given help information from @ex decorator in some log infos of command:

@ex(help="This is the helpline")
def mycommand(self):
    print(...myhelp...)

As I checked the code, all is already prepared at the lines:

cement/cement/ext/ext_argparse.py

Lines 808 to 810 in ea32057

	elif hasattr(contr, func_name):
	func = getattr(contr, func_name)
	return func()

but the information not pushed forward to the function.

810      return func(func_name, func.__cement_meta__)

That would make things much easier.

Actually, I solved that by:

@ex(help="This is the helpline")
def mycommand(self):
    func = getattr(self, self.app.pargs.__dispatch__.split('.')[1])
    print(func.__cement_meta__['parser_options']['help'])

This is a bit anoying, would prefer:

@ex(help="This is the helpline")
def mycommand(self, func_name, func_meta):
    print(func_meta['parser_options']['help'])

What do you think about that?

By the way - let me say that I am totally impressed about Cement. Very well done and great Interfaces and Abstracts. I used it some years ago and now for a new project again. I am very happy that I have choose it again. Thanks for your work!

I created a lambda which works as well

subcmdmeta = lambda a : getattr(a, a.app.pargs.__dispatch__.split('.')[1]).__cement_meta__
