Click makes python attractive for CLI's. It is far better than bash and perl for simple stuff. Fire looks useful for hacks but Click has been excellently intu

  The builtin argparse module is also really easy to use for simple stuff.

    It's ok but for some scripts it ends up being half of the code and you end up with a script that's dealing with an opaque args object. Here's a decent example of this https://github.com/pytorch/examples/blob/master/imagenet/main.py https://github.com/pytorch/examples/blob/master/imagenet/mai...

      Could you solve ghat with click much easier? This seems mostly related to various flags set up, which would need to exist in the code anyway.

        I'm saying that this should really be a function like def train( data: File, arch='resnet18', workers=4, epochs=90, start_epoch=0, batch_size=256, learning_rate=0.9, momentum=1e-4, ): ... that could be exposed as a cli if __name__ is main but otherwise can be imported in a notebook or another script.

  Perl6 has nice builtin cli construction from method definitions and doc comments cat > cli.pl6 #| Duplicates without frobnication multi sub MAIN( 'duplicate', Int $times, Str $text ) { say $text x $times; } #| Frobnicates up to a limit multi sub MAIN('frobnicate', Int :$length = 24, Bool :v(:$verbose)) { say 'Verbosity ', ($verbose ?? 'on' !! 'off'); } perl6 cli.pl Usage: cli.pl6 duplicate <times> <text> -- Duplicates without frobnication cli.pl6 [--length=<Int>] [-v|--verbose] frobnicate -- Frobnicates up to a limit perl6 cli.pl6 duplicate 3 blah... blah...blah...blah...
