Typer - Typer
Typer is a library for building CLI applications that users will love using and developers will love creating. Based on Python type hints.
I just found out about Typer, which has made my CLI life much easier. How does everyone else keep current with key utilities and packages that are being released?

CLI package recommendations, Click or Typer
For your first CLI tool I would just use `argparse`. It's worth knowing how to use because it's always available and doesn't require any extra dependencies. It's also *significantly* faster than all of the alternatives. If you're launching a long process this may not matter, but if it's a CLI for short lived commands the import time alone of some of these libraries can be a significant chunk of your runtime.

I built a CLI tool with Typer & Rich, but I think I over-engineered it
def import_wallpapers( source: Path = typer.Option(LEGACY_PATH, help="Source directory to import from"), verbose: bool = False You're kind of using the old-style typer options (and the older type annotations too - eg List instead of list, Optional[int] instead of int | None etc). Possibly this is just to support older python/typer versions, but it's worth noting that the newer way to do this is with annotations. Ie you'd write it as: source: typing.Annotated[Path, typer.Option(help="Source directory to import from") = LEGACY_PATH, This has the advantage that it preserves the python meaning of default args (eg. the function is usable as a regular function as well as a CLI descriptor), consistent with the way you write args that don't take annotation, and it lets it be type checked correctly (Option basically fudges typing by just returning Any, meaning if you put the wrong type for LEGACY_PATH, it won't be caught, and won't pass stricter checks where you forbid Any) More on reddit.com

Cool! Tiangolo is kinda a one man show. I am not sure if he actually has chops or not. Food for thought, why should I use this or typer over just click? More on reddit.com

November 1, 2022 - Typer is great, I highly recommend using rich with it for things like progress bars, and colors in print statements. It looks really slick. Trying new things, and googling lots. ... Try this... ... IPython uses pygments and prompt-toolkit, you would have better luck using those to control colours on your prompt rather than adding a third library to the mix. ... I'd suggest following a couple of Python podcasts.

Typer - Probably The Simplest To Use Python Command-Line Interface Library | Towards Data Science
January 22, 2025 - Using Python Argparse To Develop A Command-Line Interfaced Program · The module is indeed easy to use but also has some drawbacks. Therefore, in this article, I’ll introduce a 3rd party library called Typer, which I believe is probably one of the best for developing a Python CLI program.
