Syntax specific settings in sublime-project settings file

Question

A sublime-settings file enforces settings on a per-project basis:

{
    "folders": [ ... ]
    "settings":
    {
        "tab_size": 4
    }
}

How is it possible to use syntax specific settings in this file, for example to set a tab_size of 2 only for *.js files?

Answer 1

You could checkout .editorconfig.

Basically an .editorconfig file would look like,

# 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

# Matches multiple files with brace expansion notation
# Set default charset
[*.{js,py}]
charset = utf-8

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

# Tab indentation (no size specified)
[Makefile]
indent_style = tab

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

# Matches the exact files either package.json or .travis.yml
[{package.json,.travis.yml}]
indent_style = space
indent_size = 2

There's even a nice Sublime Text package that automatically reads and understands them. Just throw your .editorconfig in version control and you're ready to go.
