Automatically add commands to JS/Python packages

[syrusakbary]

NPM and Python packages should automatically add the available commands and

Similarly to Zig in Python, where people can do:

python -m ziglang {YOURCOMMANDTOZIG}

Or similarly to cowasm

~$ npx python-wasm@latest

How this should work?

If the package has an entrypoint command, that should be run by default relying the args.

JS

In JS, we should add all the runnable webc commands inside of the bin:

package.json

{
  ...
  "bin": { "COMMAND_NAME": "./bin/COMMAND_NAME" },
}

Python

In Python, we can rely on the

setup.py

setup(
    ...
    entry_points={'console_scripts': [
        'COMMAND_NAME = PACKAGE_NAME.commands:FUNCTION_COMMAND',
    ]},
)
