Recommendations on file/dir/module structure, common dependencies, and/or anti-patterns for writing CLI tool in Rust

1. starship

   1 329 57,928 9.7 Rust

   ☄🌌️ The minimal, blazing-fast, and infinitely customizable prompt for any shell!

   

   I'm quite new to Rust, and have been trying to learn more by working on some real solution I could see myself benefitting from, which happens to be a CLI tool at this time. I know there are some great tools written in Rust which I use day to day (such as Starship, bat, exa, etc.), but I wanted to hear experts' suggestions / recommendations on any project I should check out for clean, clear, and extensible structure (or lack thereof), and any dependencies I should start with / avoid.

3. bat

   A cat(1) clone with wings.

4. tokio

   3 235 32,208 9.6 Rust

   A runtime for writing reliable asynchronous applications with Rust. Provides I/O, networking, scheduling, timers, ...

   

   The main focus of the CLI tool would be around working on filesystem, and also making several network requests simultaneously. Although some may argue it would be easier/faster writing in other languages, this is more for my own learning to write in Rust. It will be a simple toy project at first, but I'd like to prepare for more complex Rust programming in the future with it. For instance, I see different directory / file / module structures used, Rust version / edition differences here and there, some common dependencies such as Tokio, etc.

5. exa

   4 132 24,411 3.0 Rust

   A modern replacement for ‘ls’.

6. flux2

   5 119 8,164 9.1 Go

   Open and extensible continuous delivery solution for Kubernetes. Powered by GitOps Toolkit.

   

   Flux CLI (for Flux, GitOps) for Cobra based implementation with a clean and extensible setup

7. cobra

   6 151 44,062 7.2 Go

   A Commander for modern Go CLI interactions

8. cli

   7 318 44,736 9.9 Go

   GitHub’s official command line tool

   

   I personally prefer GitHub CLI implementation over Flux's, as the most of the implementation details are handled in separate, "internal" packages, making their responsibilities clear

9. mkcert

   8 149 58,813 1.9 Go

   A simple zero-config tool to make locally trusted development certificates with any names you'd like.

   

   mkcert for small dependency footprint - a bit more lengthy implementation but the code base is easy enough to follow

10. kubectl

    9 13 3,293 9.5 Go

    Issue tracker and mirror of kubectl code

    

    kubectl is for sure battle tested, but it involves very Kubernetes specific implementations and is going to be too complicated for the first pointer

11. glow

    10 85 25,590 7.2 Go

    Render markdown on the CLI, with pizzazz! 💅🏻

    

    Charm's Glow is a joy to use, a good example of having the Charm's Bubbletea usage - but from the code perspective, it's a bit difficult to navigate as many code paths are put in the same package

12. bubbletea

    11 163 42,853 9.6 Go

    A powerful little TUI framework 🏗
