Crate List - Blessed.rs
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".

Need a new args parser
That's because the maintainer does not consider it an issue but an implementation detail: https://github.com/RazrFalcon/pico-args/issues/15
-
An alternative to clap but with a stable API?
Maybe pico-args then?
-
Immediately off the top of your head what is the best Rust CLI library.
If I forget to get around to it, would you mind poking RazrFalcon/pico-args about adding it to the comparison chart? I really like using that thing as something I can link people to with just a quick explanation of that particular trade-off.

Best CLI arg parser for use in Rust to port from Perl with Getopt::Long?
If fewer dependencies is better, you can't get much fewer than pico-args, which has zero dependencies.
- What is the current proper way to get command line args ?

Creating an Argparse library [feedback would be appreciated]
You might also want to check out pico-args, Gumdrop, and lexopt to see if any of them meet your needs.

New:`cargo-fuzzcheck` 0.5.0 and a series of decent, fast-to-compile crates to replace `syn`, `quote`, `serde-json`, and `toml-rs`
For example, I'd love to go from StructOpt to Gumdrop for parsing command-line arguments and cut my compile times and output size by an order of magnitude, but Gumdrop uses String internally, which means it'll panic if it encounters a Windows path with un-paired surrogates or a mojibake'd posix path... some of which I actually have.
What are some alternatives?
