Re: CLI parsing—with `--help` text—`--foo bar`, how to give additional parameters to `bar`?

Yeah, but the risk with config files is you need a website—and/or full JSON schema output—to figure out what’s needed. (Although I should mention that with my doctrans project you can generate a config class—and class method—from/to your argparse parser; enabling the config file scenario rather

Re: Re: CLI parsing—with `--help` text—`--foo bar`, how to give additional parameters to `bar`?

Yeah I've played with custom actions before https://github.com/offscale/argparse-utils/tree/master/argparse_utils/actions But this would only help in one phase, the important phase of providing help text will need to be provided out-of-argparse and thrown in (like my trivial absl alternative,

Re: CLI parsing—with `--help` text—`--foo bar`, how to give additional parameters to `bar`?

Hi Dan, The feature that existing CLI parsers are missing is a clean syntax for specifying options on the second parameter (the "value"), where there may be different options available depending on which you choose. For example: https://www.tensorflow.org/api_docs/python/tf/keras/optimizers/Adam

Hi Sam, I’ve been using abseil python API. https://abseil.io/docs/python/guides/flags https://abseil.io/docs/python/quickstart It’s a distributed command line system with features that appear to support

Yes it’s my module, and I’ve been using argparse https://github.com/SamuelMarks/ml-params No library I’ve found provides a solution to CLI argument parsing for my use-case. So I’ll write one. But what should it look like, syntactically and semantically? On Fri, 16 Oct 2020 at 3:14 am, Dieter
