clip

A command line parser that doesn't use std or alloc!

Why?

I mainly did this for educational purposes. I've never written a library that did not use the std or alloc crates, so I wanted to learn how.

I also think the portability of this crate will be useful in implementing Rusty-CI

Example

```rust extern crate clip;

use clip::App; use std::env::args;

fn main() { let strings = &args().collect::>()[..]; let values: Vec<&str> = strings.iter().map(|s| &**s).collect();

let mut app = App::new(&values[1..])
            .name("name")
            .flag("--input", 1)
            .flag("--output", 1)
            .flag("--link", -1)
            ;
app.parse();

println!(
    "name: {}\ninput: {}\noutput: {}\nlink: {:?}",
    app.get("name")[0],
    app.get("--input")[0],
    app.get("--output")[0],
    app.get("--link"),
)

} ```
