Click-rs
A Rust clone of Python's click, built on the structopt crate.
Documentation
Find it on Docs.rs.
Example
Unfortunately, for the time being, structopt
must also be installed.
Re-implementing the example from structopt
, add clickrs
and structopt
to your dependencies of your Cargo.toml
:
[dependencies]
clickrs = "0.1"
structopt = "0.3"
And then, in your rust file:
use clickrs::command;
use std::path::PathBuf;
#[command(name = "basic")]
#[argument("debug", short, long)]
#[argument("verbose", short, long, parse(from_occurrences))]
#[argument("speed", short, long, default_value = "42")]
#[argument("output", short, long, parse(from_os_str))]
#[argument("nb_cars", short = "c", long)]
#[argument("level", short, long)]
#[argument("files", name = "FILE", parse(from_os_str))]
fn main(
debug: bool,
verbose: u8,
speed: f64,
output: PathBuf,
nb_cars: Option<i32>,
level: Vec<String>,
files: Vec<PathBuf>,
) {
println!("{:?}", speed);
}
Using this example:
$ ./basic
error: The following required arguments were not provided:
--output <output>
USAGE:
basic --output <output> --speed <speed>
For more information try --help
$ ./basic --help
basic 0.1.0
USAGE:
basic [FLAGS] [OPTIONS] --output <output> [--] [FILE]...
FLAGS:
-d, --debug
-h, --help Prints help information
-V, --version Prints version information
-v, --verbose
OPTIONS:
-l, --level <level>...
-c, --nb-cars <nb-cars>
-o, --output <output>
-s, --speed <speed> [default: 42]
ARGS:
