RegExp Is Intraline

A function that tells you whether a RegExp is confined to the line it's executed on or not.

Essentially if the RegExp cannot possibly match a newline character, either \r or \n, then it's "intraline".

All features up to ES2025 are supported.

Install

npm install regexp-is-intraline

Usage

import isIntraline from 'regexp-is-intraline';

// Let's check if some regexes are intraline or not

isIntraline ( /hello/ ); // => true
isIntraline ( /hello\nworld/ ); // => false
