A crate for stripping ANSI escape sequences from byte sequences.

This can be used to take output from a program that includes escape sequences and write it somewhere that does not easily support them, such as a log file.

Examples

The strip function accepts bytes and returns a Vec of bytes with ANSI escape sequences removed.

extern crate strip_ansi_escapes;

use std::io::{self, Write};

fn work() -> io::Result<()> {
  let bytes_with_colors = b"\x1b[32mfoo\x1b[m bar";
  let plain_bytes = strip_ansi_escapes::strip(&bytes_with_colors);
  io::stdout().write_all(&plain_bytes)?;
  Ok(())
}

fn main() {
    work().unwrap();
}

For writing directly to a writer, the Writer struct may be preferable.

extern crate strip_ansi_escapes;

use std::io::{self, Write};
use strip_ansi_escapes::Writer;

fn work() -> io::Result<()> {
  let bytes_with_colors = b"\x1b[32mfoo\x1b[m bar";
  let mut writer = Writer::new(io::stdout());
  // Only `foo bar` will be written to stdout
  writer.write_all(bytes_with_colors)?;
  Ok(())
}

fn main() {
    work().unwrap();
}
