[Python-Dev] New Module: CommandLoop (original) (raw)

@cmdloop.aliases('goodbye') @cmdloop.shorthelp('say goodbye') @cmdloop.usage('goodbye TARGET')

to just: @cmdloop.addspec(aliases=['goodbye'], shorthelp ='say goodbye', usage='goodbye TARGET') leaving the possibility of multiple decorators when one line gets to long: @cmdloop.addspec(aliases=['goodbye'], shorthelp ='say goodbye') @cmdloop.addspec(usage='goodbye TARGET # where TARGET is a filename in the current directory')

Well, why not support both, and leave it up to the user?

Having only one method keeps the API simple. Also, the addspec() approach allows the user to choose between single and multiple lines.

BTW, addspec() could be made completely general by supporting all possible keywords at once:

def addspec(**kwds): def decorator(func): func.dict.update(kwds) return func return decorator

With an open definition like that, users can specify new attributes with less effort.
