LF stands for "line feed," but you're probably more familiar with the term newline (the escape sequence \n). Then, we'll look at how this affects the typical developer experience on a multi-OS codebase. Their history dates back to the era of the typewriter, so we'll briefly look at how that works so you understand why we have two different control characters rather than just one. LF and CR are two such control characters, and they're both related to line endings in files. They aren't used to render visible characters rather, they're used to perform unique actions, like deleting the previous character or inserting a newline. A certain subset are control characters, also known as non-printing characters. Interestingly, the ASCII standard isn't just for visible characters like letters and numbers. The ASCII standard is that system-it maps characters like A and z to numbers, bridging the gap between human languages and the language of computers. Since the files on your computer consist of strings of human-readable characters, we need a system that allows us to convert back and forth between these two formats. It's how you're reading this post right now! But computers can only understand and work with numbers. People use letters, numbers, and symbols to communicate with one another. LF line endings, we need to brush up on a bit of typesetting history. To really understand the problem of CRLF vs.

However, I do encourage reading the full post to understand how these things work under the hood-you'll (hopefully) never have to Google line endings again!ĬRLF vs.
History can be boring, though, so if you stumbled upon this post after hours of frustrated research, you can skip straight to A Simple.

Before we look at how that's done, we'll briefly review the history behind line endings on Windows and Unix so we can understand why this issue exists in the first place. gitattributes file to your repo so you can enforce line endings consistently in your codebase regardless of what operating systems your developers are using. If just one person forgets to configure their line endings correctly, you'll need to re-normalize your line endings and recommit your files every time a change is made.Ī better solution is to add a. For the sake of comprehensiveness, we'll look at how that can be done in this article, but it isn't ideal if you're on a large team of developers. The typical advice is to configure your local Git to handle line ending conversions for you.

LF line endings is actually fairly popular-you'll find tons of questions on StackOverflow about how to configure software like Git to play nicely with different operating systems. If you've ever worked on a project where developers use different operating systems, you know that line endings can be a peculiar source of frustration.
