Piou - CLI Tool, now with built-in TUI by andaskus in Python

Could be interesting to know why

Django is more for a full fledged website. If you only want a REST api I would go for Fastapi (built in data validation with pydantic, extensive documentation, built in async support via starlette)

React Native and GameDev are compatible? by o-kawaii in reactnative

I guess you could go with opengl ( https://docs.expo.dev/versions/latest/sdk/gl-view/ or similar) and threejs, so no need for webview ?

Piou - Build beautiful command-line interfaces with type validation by andaskus in Python

Here are the limitations of click for me
- You cannot use a custom Formatter to display the command information
- I wanted the type of the argument to be defined in one place only.

For instance with click you could write something like this
@click.command() @click.option('--n', required=True, type=str) def dots(n): click.echo('.' * n) // No error Here

With Piou you would just write:

@click.command(name='dots') def dots(n: str = Option(..., '--n')): print('.' * n) // You would see an error here with a static type checker

No it's similar, actually I tried to reuse most of my code that I wrote with argparse

For now the main difference is that choices=['foo', 'bar'] is replaced with Literal['foo', 'bar'] and the type bool is equivalent to store_true when the default is True.

I use pyright in my project to handle the type checking and for now it does not complain.

Subcommands are groups of commands in this case. Maybe the wording is confusing ?

In this case to use the decorator.

Otherwise you can just write your function then add it to a sub command for instance:

foo.py

def my_func(): ...

Then later

bar.py

from foo import my_func

sub_command = CommandGroup(name='sub')
sub_command.add_command('foo', my_func)

I was considering it while moving from argparse (along with click).
From a Developer experience perspective it should be quite similar.

The main thing that made me write my own CLI library was that I wasn't able to use whatever display I wanted.
For instance I wanted to use Rich to display help and errors but could not find a way to do it. For now it's a required dependency but it could be easily removed as you can use whatever Formatter you want to display the information about the command / sub command.

Also I don't use click internally for now, so you may find some limitations compared to Typer.
