Per-Project Whitespace with EditorConfig

By on  

Standards can change from project to project.  Single quotes or double quotes?  MooTools, Dojo, or micro-frameworks?  And then the question that has started wars:  spaces or tabs?  I'm a tab guy myself but the team that I work on has set a two-space standard.  It's not my preference but it was a team decision so I have to drink the Kool-Aid.  I still want to use my typical tab whitespace on other projects but just this one project should use spaces.  I thought this would be a nightmare but enter EditorConfig, a utility with plugins for several text editors which allows developers to specify settings per project.

Start by creating a .editorconfig and placing it at the root of the project which you'd like to create whitespace for:

touch .editorconfig

Once the file is in place, it's up to you to set the spacing settings per file type as you wish:

# EditorConfig is awesome: http://EditorConfig.org

# top-most EditorConfig file
root = true

# Unix-style newlines with a newline ending every file
[*]
end_of_line = lf
insert_final_newline = true

# 4 space indentation
[*.py]
indent_style = space
indent_size = 4

# Tab indentation (no size specified)
[*.js]
indent_style = tab

# Indentation override for all JS under lib directory
[lib/**.js]
indent_style = space
indent_size = 2

So not only can you set spacing per project but you can set them per file too.  I've found EditorConfig to be a lifesaver as I can code per usual without having to think about spaces or tabs.  EditorConfig made my day!

    In Notepad++ you can change the indent behaviour clicking on Preferences / Tab Settings and defining the tab width and characters as a general behaviour or on a per language basis.

  2. I recently started a repo of my editorconfig, lint config, and sublime text user preferences, this way I always have them and can keep several machines in sync.
