What is slice-ansi?

The slice-ansi npm package is designed for slicing strings with ANSI escape codes without breaking the visual appearance. This is particularly useful for terminal applications where text styling (like colors, bold, underline) is applied through ANSI escape codes. It allows developers to extract or truncate portions of the styled text without losing or corrupting the intended styles.

What are slice-ansi's main functionalities?

Slicing styled strings

This feature allows you to slice a string that contains ANSI escape codes, ensuring that the visual styling is preserved in the sliced string. The code sample demonstrates how to slice a string that starts with red-colored text and then resets to default color. The sliced result contains only the portion of the string within the specified range, along with the necessary ANSI codes to maintain the original styling.

const sliceAnsi = require('slice-ansi');
const input = '\u001B[31mThis is red\u001B[39m and this is not.';
const sliced = sliceAnsi(input, 0, 10);
console.log(sliced);
