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_scriptI 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.
