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.

[self-made] havn - fast lightweight port scanner
I’m not sure why I decided to create it, I think I tried to use RustScan for a simple task last week, but it was too convoluted for my needs, as well as the fact that it requires nmap to be installed. Thus havn was born, nothing else needed, and only directly using two dependencies, Tokio and Clap, although I think If I really wanted to, I could remove the Clap dependency, but it’s just so handy and easy to use.

What's the coolest Rust project you've seen that made you go, 'Wow, I didn't know Rust could do that!'?
Hope you are aware that structopt is in maintenance mode and is merged into clap as of v3.

Task manager for Linux using rust
As I understood you need to implement a command line argument parser for that you can use clap https://github.com/clap-rs/clap or structopt https://github.com/TeXitoi/structopt.

clap 3.1: A step towards 4.0
Something I've been giving thought to is how to help structopt users discover that clap3 is their upgrade path. We've put notices in the structopt repo but cargo upgrade and docs.rs won't say anything. See https://github.com/TeXitoi/structopt/issues/525 for more ideas we're considering.

ANN: clap 3.0.0-rc.0!
For myself, I have found serde.rs really useful for undertanding their derives while I've always been frustrated with finding anything in structopt's documentation, so I modeled it more off of serde. This ended up both being in structure and not being in docs.rs. I think it really was the structure that was the frustration point for me but there was interest elsewhere in moving stuff out of docs.rs.
Not too sure, actually. I've started a conversation about this.
To add, StructOpt had an example for this case.

fncmd: Command line interface as a function.
I think it would be nice to have a comparison to clap-derive and/or structopt in the README, as that is what I expect most users would compare this to. The subcommand handling looks especially cumbersome compared to deriving on structs and enums.

It is written in Rust using the structopt and swayipc crates. It is published on crates.io. The repository is hosted on GitLab. The repository is mirrored on GitHub.
