Write colored strings with ANSI escape code into a termcolor terminal.

This package provides a single function, write_ansi, which parses ANSI escape codes in the provided byte string and transforms them into the corresponding termcolor commands. The colors will be supported even on a Windows console.

The main purpose of this package is to forward colored output from a child process.

extern crate termcolor;
extern crate fwdansi;

use termcolor::*;
use std::io;
use std::process::Command;
use fwdansi::write_ansi;

fn main() -> io::Result<()> {
    let output = Command::new("rustc").args(&["--color", "always"]).output()?;

    let mut stderr = StandardStream::stderr(ColorChoice::Always);
    write_ansi(&mut stderr, &output.stderr)?;
    //^ should print "error: no input filename given" with appropriate color everywhere.

    Ok(())
