unfrustrating python CLI

Project description

Sometimes I just want to execute a python callback and pass args/kwargs on the CLI, and not have to define any custom CLI entry point of any sort, nor change any code, typically when automating stuff, cli2 unfrustrates me:

cli2 yourmodule.yourcallback somearg somekwarg=foo

Sometimes I just want to define a new command and expose all callables in a module and I can’t just do it with a one-liner. cli2 unfrustrates me again:

console_script = cli2.ConsoleScript(__doc__).add_module('mymodule')
# then i add console_script entrypoint as such: mycmd = mycmd.console_script

I also like when readonly commands are in green, writing commands in yellow and destructive commands in red, I find the commands list in the help output more readable, and directive for new users of the CLI:

@cli2.config(color=cli2.RED)
def challenge(dir):
   '''The challenge command dares you to run it.'''
   os.exec('rm -rf ' + dir)

Of course then there’s all this code I need to have coverage for and I’m still so lazy that I still don’t write most of my test code myself, so I throwed an autotest function in cli2 (“ala” dbunit with a personal touch) that I can use as such:

@pytest.mark.parametrize('name,command', [
    ('cli2', ''),
    ('help', 'help'),
    ('help_debug', 'help debug'),
    # ... bunch of other commands
    ('debug', 'debug cli2.run to see=how -it --parses=me'),
])
def test_cli2(name, command):
    cli2.autotest(
        f'tests/{name}.txt',
        'cli2 ' + command,
    )

You should be able tho pip install cli2 and start using the cli2 command, or cli2.ConsoleScript to make your own commands.
