python callables from CLI too !

cli2: python callables from CLI too !

Install cli2 ie.:

$ pip3 install --user cli2

Cli2 can be used as a generic command line to execute callbacks and print docstrings:

$ cli2 --debug your.callback
$ cli2 your.callback arg0 kwarg0=aoeu

, or as a CLI framework: first give it a name in the console_scripts entry point like yourapp and point it to cli2:console_script, example using setupmeta’s entry_points.ini:

[console_scripts]
yourapp = cli2:console_script

Then register your commands easily, ie:

[yourapp]
# bind yourapp help to cli2.help
yourapp help = cli2.help
# bind yourapp run to yourapp.cli.run
yourapp run = yourapp.cli.run
# bind yourapp * to callbacks in yourapp.cli
yourapp * = yourapp.cli

Help:

Clitoo makes your python callbacks work on CLI too !

This CLI can execute python callbacks with parameters.

Clitoo recognizes 4 types of command line arguments:

- lone arguments are passed as args
- arguments with = are passed as kwargs
- dashed arguments like -f arrive in context.args
- dashed arguments like -foo=bar arrive in context.kwargs

It doesn't matter how many dashes you put in the front, they are all
removed.

To use the context in your callback just import the clitoo context::

    from clitoo import context
    print(context.args, context.kwargs)

Clitoo provides 2 builtin commands: help and debug. Any other first
argument will be considered as the dotted path to the callback to import
and execute.

Examples:

clitoo help your.mod.funcname
    Print out the function docstring.

clitoo debug your.func -a --b --something='to see' how it=parses
    Dry run of your.mod with arguments, dump out actual calls.

clitoo your.mod.funcname with your=args
    Call your.mod.funcname('with', your='args').

Demo:

$ clitoo debug your.func -a --b --something='to see' how it=parses
Could not import your.func nor clitoo.your.func
Args: ('how',)
Kwargs: {'it': 'parses'}
Context args: ['a', 'b']
Context kwargs: {'something': 'to see'}

Fallbacks

Clitoo will attempt to fallback on packages of its own. If it doesn’t find the git.clone callback from the git package, or doesn’t find the git package itself, it will find clitoo.git.clone which is a builtin command that we use in CI.

Making your own command

See the djcli repository for an example of command that is packaged as standalone, but it looks like:

# Declare the following as CLI entry_point
def cli():
    clitoo.context.default_module = __name__
    return clitoo.main()
