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.
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(); }
