Click-rs

基于click的Rust克隆版本，构建在structopt crate之上。

文档

在Docs.rs上找到。

示例

遗憾的是，目前还需要安装structopt。重新实现structopt的示例，将clickrs添加到你的Cargo.toml的依赖中

[dependencies]
clickrs = "0.1"
structopt = "0.3"

然后，在你的rust文件中

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);
}

使用此示例

$ ./basic
error: The following required arguments were not provided:
    --output <output>

USAGE:
    clickrs --output <output> --speed <speed>

For more information try --help

$ ./basic --help

USAGE:
    clickrs [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]
