sl-liner

A Rust library offering readline-like functionality.

This was forked from https://gitlab.redox-os.org/redox-os/liner. It has some changes to history (non-duplicating and context sensitive by default) and it supports Windows (10 with an ansi escape capable console).

In Cargo.toml:

sl_liner = "https://github.com/sl-sh-dev/sl-liner"
...

In src/main.rs:

extern crate liner;

use liner::{Context, Completer};

struct EmptyCompleter;

impl<W: std::io::Write> Completer<W> for EmptyCompleter {
    fn completions(&mut self, _start: &str) -> Vec<String> {
        Vec::new()
    }
}

fn main() {
    let mut con = Context::new();

    loop {
        let res = con.read_line("[prompt]$ ", &mut EmptyCompleter).unwrap();

        if res.is_empty() {
            break;
        }

        con.history.push(res.into());
    }
}

See src/main.rs for a more sophisticated example.
