fast-slice-ansi

A fast String#slice which supports ANSI escape sequences.

Inspired by slice-ansi, this comes with various performance improvements.

Install

npm i -S fast-slice-ansi

Usage

import {sliceAnsi} from 'fast-slice-ansi';
import {styleText} from 'node:util';

const input = `Hello ${styleText('blue', 'blue')} world`;

const result = sliceAnsi(input, 6);
// result: '\u001b[34mblue\u001b[39m world'

Options

An options object can be passed which has the following properties:

• visual: If true (default), slices operate against the visual representation of the string (e.g. a surrogate pair is counted as one character)

Example:

sliceAnsi(input, 0, 3, {visual: false});
