How to use it?

rust extern crate commander; use td_rlua::Commander;

Option parsing

Options with commander are defined with the .option(),.option_str(),.option_int(),.option_float(),.option_list() method. The example below parses args and options from std::env::args() or Vec<String>, leaving remaining args can get by func .get(), .get_str(), .get_int(), .get_float(), .get_list().

```rust extern crate commander; use commander::Commander;

fn main() { let command = Commander::new() .version(&env!("CARGOPKGVERSION").tostring()) .usage("test") .usagedesc("Copy SOURCE to DEST, or multiple SOURCE(s) to DIRECTORY.") .optionlist("-l, --list [value]", "list", Some(vec!["a".tostring(), "b".tostring(), "c".tostring()])) .optionint("--enum [value]", "enum", None) .optionint("-d, --debug [value]", "debug", Some(123)) .optionstr("-c, --copy [value]", "copy content", Some("source".tostring())) .option("-r", "enable recursive", None) .parseenvor_exit() ;

if let Some(s) = command.get_str("c") {
    println!("arg c = {}", s);
}

if let Some(s) = command.get_str("copy") {
    println!("arg copy = {}", s);
}

if let Some(d) = command.get_int("d") {
    println!("arg d = {}", d);
}

if let Some(e) = command.get_int("enum") {
    println!("arg enum = {}", e);
}

if let Some(l) = command.get_list("list") {
    println!("arg list = {}", l);
}

if let Some(r) = command.get("r") {
    println!("arg r = {}", r);
}

} ```

The output info if you build bin is test. follow examples show. 1. ./test -c xxxx -d arg c = xxxx arg copy = xxxx arg d = 123 //arg c and copy is the same arg, and we has d param but we not set the value, it read from default:123

1. ./test -h #it will show help then exit the program ``` Usage:./test test Copy SOURCE to DEST, or multiple SOURCE(s) to DIRECTORY.

Options: -v, --version Show the bin version and build time -h, --help Show this help message and exit -l, --list [value] list default:a, b, c --enum [value] enum -d, --debug [value] debug default:123 -c, --copy [value] 拷贝内容 default:aaa -r enable recursive ```

1. ./test -v #it will show version and show build time then exit the program Version:0.1.1 Build Time:2017-04-29T14:11:24+08:00

2. ./test --enum aa -r --list aa bb cc #we provide enum and list arg arg list = ["aa", "bb", "cc"] arg r = true // we has the arg enum, but the enum is not a vaild int, so convert failed, and we provide arg r, so r is true
