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

November 1, 2022CLI 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.

r/learnpython on Reddit: I built a CLI tool with Typer & Rich, but I think I over-engineered it
January 22, 2026 -
Hi everyone, I've been trying to level up my Python structure skills, so instead of writing a simple bash script to manage my wallpapers, I decided to build a full Python CLI tool.
The Project: It's called Scenery. It indexes local images, extracts dominant colors (using Pillow and Colorgram), prevents duplicates via MD5 hashing, and displays a TUI table with previews using Rich.
My Concern: It works great, but I feel like I might have over-engineered the architecture for what is essentially a file manager. I split the logic into core, cli, and config modules and used a YAML-based manifest.
I'm looking for feedback on: Is the project structure logical for a CLI this size? Am I using Typer patterns correctly? General code quality/readability.
Repo: https://github.com/Doble-2/scenery-wallpapers
Be as harsh as you want! I want to learn "Production-Ready" standards. Thanks!

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.

r/learnpython on Reddit: CLI package recommendations, Click or Typer
March 1, 2025 -
Anyone have recommendations on using Click or Typer for my first CLI tool? Click looks good and claims to solve some problems of argpase and typer. I am leaning towards using it but wanted to see how people view using that as opposed to just argpase. I hope it will be a good project with collaborators so I want to start the project off with something that works well and has good base for other collaborators.
