Ensuring editing consistency with .editorconfig

 
Today I updated my recently created GitHub repo configs to include my .editorconfig file. EditorConfig is one of those incredibly simple ideas that I initially hesitated to install (“is that all it does?”) but now find invaluable. By defining a few properties in a file that you store in your repo, usually in the root, you can go some way to ensuring that everyone that works on your source uses the same basic whitespace settings; indent style, indent size, line terminator, and so on.

Nowadays, many (most?) editors allow for settings at both the user and project level, but often a project repo doesn’t include a settings file for the project or, if it does, it’s for an editor that you don’t use. If you work on multiple projects with differing conventions or even just in a team where everyone uses their own favourite editor, EditorConfig can ensure consistency of layout and less time wasted in reformatting.

EditorConfig consists of two parts; a simple configuration file, .editorconfig, and an editor/IDE plugin. Once you have selected and installed the plugin for your preferred editor (at the time of writing there were over twenty available) you can set your preferences and you’re ready to go. As it’s a simple text file it can be checked into your repo to ensure that everyone working on your project shares the same settings.

The config file allows eight properties to be set with seven of them allowing you to control the appearance of your code.

EditorConfig is one of those things, like Markdown formatted ReadMe’s, that has become ubiquitous in open source projects. Even a cursory browse through GitHub or BitBucket will reveal that many projects make use of it.

My own .editorconfig can be found in my configs repo, a small collection of my most-used config files on GitHub.
