regex_ansi

High‑fidelity Rust port of the popular JavaScript ansi-regex pattern. Supplies a battle‑tested regular expression that matches ANSI escape sequences (CSI, OSC, etc.).

Example

use regex_ansi::ansi_regex;

fn main() {
    let text = "\x1b[31mError:\x1b[0m something failed";
    let cleaned = ansi_regex().replace_all(text, "");
    assert_eq!(cleaned, "Error: something failed");
}

Features

• Constant, pre‑audited pattern identical in semantics to ansi-regex@6 (JS).
• Two ready regex constructors: global style (ansi_regex) and first match style (ansi_regex_first).
• No unsafe code.

API

• pub fn ansi_regex() -> &'static regex::Regex
• pub fn ansi_regex_first() -> &'static regex::Regex
• pub fn pattern() -> &'static str – raw pattern string.

Performance Notes

• The OSC portion is implemented using a negated character class for linear behavior.
