API Usage

Set line endings in file

import { setLineEndings } from 'crlf-es';

await setLineEndings('./my-file.txt', 'CRLF');

Set line endings in multiple files

import { setLineEndings } from 'crlf-es';

// Uses NodeJS fs.glob
await setLineEndings('./files/**/*.txt', 'LF');

// Also accepts array
await setLineEndings(['./files/**/*.txt', './other-files/**/*.txt'], 'CRLF');

Get line endings for file

import { getFileLineEndings } from 'crlf-es';

await getFileLineEndings('./my-file.txt', 'LF');

Get line endings for string

import { getStringLineEndings } from 'crlf-es';

const myString =
    'Aut adipisci sit qui.\r\nEnim quibusdam accusamus cum fugiat.\r\nOfficiis qui veritatis facilis sint tempora impedit';

const result = await getStringLineEndings(myString);
// result = CRLF
