crlf

Detect and change line endings

Usage

The cli is probably the one you're looking for, first npm install -g crlf.
Usage is something like this:

 $ crlf index.js
index.js CRLF
$ crlf *.js
index.js CRLF
test.js LF
$ crlf --set=LF *.js
index.js CRLF -> LF
test.js LF -> LF
$ crlf index.js
LF

Here's the API usage

 var crlf = require('crlf');

crlf.get(__dirname + '/package.json', null, function(err, endingType) {
  console.log(endingType); // LF
});
crlf.set(__dirname + '/package.json', 'CRLF', function(err, endingType) {
  console.log(endingType); // LF
  // file was using LF and now uses CRLF
});
