line-ending-corrector

Line Ending Corrector - A utility that makes sure your files have consistent line endings.

It converts all those pesky \r\n (a.k.a CRLF) line endings in Microsoft Windows operating systems into the more commonly used and recognized \n (a.k.a LF). Though it lets you do the opposite as well ( converting LF to CRLF ). It supports \r (a.k.a CR) as well for the sake of completion.

You should definitely have this in your build process especially if someone in your team works from a non UNIX system.

Features

• Supports recusive mode for all files in a directory

• Has a gulp module
• Exposes a programmatic API.
