https://github.com/google/argh is another minimal library for CLI argument parsing that could be in the list

Rust Web Framework Comparison
My go-to is argh[1], as it's more lightweight while still providing a nice derive-based API.

Immediately off the top of your head what is the best Rust CLI library.
It'll panic if the path contains non-UTF8-able bytes.

fncmd: Command line interface as a function.
Yes clap needs a lot of boilerplate that small programs don't always need, but if you're going to simplify it, I don't think having a bunch of arguments given to the main function is better than having an option struct as in argh. Such an option struct can be given to other functions from the main, can have dedicated consistency check or completion methods, etc.

Newbie frustration: can we KISS more?
Typically programs are configured through a config object. People like to use things like clap, structopt, or argh for passing in arguments through the CLI https://github.com/google/argh. You can also use the env! macro for embedding values in at compile time, or by going through the std::env::var infrastructure for runtime env vars.

Darkroom: A VCR contract testing tool built in Rust
Until the argh crate bumps their version I cannot updater the version on crates.io so the install command currently is: cargo install --git https://github.com/mkatychev/darkroom

Announcement: xflags, fast-to-compile proc macro for cli args
Ahh. The secondary reason I discounted Argh as "unsuitable for purpose" after "Doesn't support using OsString under the hood".

CLI Contexts
I recently came across this question (and associated answer) on the clap repository. The answer given is a good one. But I wanted to expand with my own findings and practices, which spurred the motivation for this post.

Getting Started with CLI tools in Rust using Clap
We can also use tuple-like struct syntax and named-field struct syntax for enum variants within our enum; this is because unlike in other OOP languages, Rust enums are actually sum types. You can read more about how powerful Rust enums are in another article we wrote here. You can have optional arguments by simply wrapping the types in Option, but if you want to add a flag to a command you can use bool, since clap recognises that flags are either there or not there. Let's have a look at what this might look like:

Flow Updater JSON Creator
I began by developing a wrapper for the CurseForge API, which turned out to be a lengthy and challenging process but constituted the bulk of the work. Next, I coded the CLI, which was relatively straightforward. Instead of using the clap crate, a Rust tool for generating CLIs, I opted for the following line of code:
-
netcrab: a networking tool
By this time I had already gotten tired of parsing arguments by myself and had looked for something to help with that. I found a really dang good argument parsing library called clap. What makes it so cool is it's largely declarative for common uses. You simply mark up a struct with attributes, and the parser automatically generates the usage and all the argument parsing code.

I made an alternative --help renderer for clap based applications
Is this just referring to wrapping based on the terminal width? That is supported with the wrap_help feature though I have been considering making it a default feature.

Looking for advice around project direction using artix-web
CLI, use Clap. If you want to get fancy, use Tui.

Build a HTTP server with Rust and tokio - Part 1: serving static files
As our CLI is getting more complex, we'll use the clap crate to parse the command line arguments.
