1.1.1 package.el

This package is available from MELPA, MELPA Stable and NonGNU ELPA. Install from these repositories and enable global minor-mode editorconfig-mode:

(editorconfig-mode 1)

Normally, enabling editorconfig-mode should be enough for this plugin to work: all other configurations are optional. This mode sets up hooks so that EditorConfig properties will be loaded and applied to the new buffers automatically when visiting files.

1.1.2 use-package

If you use use-package, add the following to your init.el file:

(use-package editorconfig
  :ensure t
  :config
  (editorconfig-mode 1))

1.1.3 Manual installation

Copy all .el files in this repository to ~/.emacs.d/lisp and add the following:

(add-to-list 'load-path "~/.emacs.d/lisp")
(require 'editorconfig)
(editorconfig-mode 1)

1.2.1 File Type (file_type_ext, file_type_emacs)

File-type feature is currently disabled, because this package is now undergoing big internal refactoring. For those who want this functionality, please consider using editorconfig-custom-majormode.

1.3.1 editorconfig-trim-whitespaces-mode

Buffer local minor-mode to use to trim trailing whitespaces.

If set, editorconfig will enable/disable this mode in accord with trim_trailing_whitespace property in .editorconfig. Otherwise, use Emacs built-in delete-trailing-whitespace function.

One possible value is ws-butler-mode, with which only lines touched get trimmed. To use it, add following to your init.el:

(setq editorconfig-trim-whitespaces-mode
      'ws-butler-mode)

1.3.2 editorconfig-after-apply-functions

(Formerly editorconfig-custom-hooks)

A list of functions which will be called after loading common EditorConfig settings, when you can set some custom variables.

For example, web-mode has several variables for indentation offset size and EditorConfig sets them at once by indent_size. You can stop indenting only blocks of web-mode by adding following to your init.el:

(add-hook 'editorconfig-after-apply-functions
  (lambda (props) (setq web-mode-block-padding 0)))

1.3.3 editorconfig-hack-properties-functions

A list of functions to alter property values before applying them.

These functions will be run after loading ".editorconfig" files and before applying them to current buffer, so that you can alter some properties from ".editorconfig" before they take effect.

For example, Makefile files always use tab characters for indentation: you can overwrite "indent_style" property when current major-mode is makefile-mode:

(add-hook 'editorconfig-hack-properties-functions
          '(lambda (props)
             (when (derived-mode-p 'makefile-mode)
               (puthash 'indent_style "tab" props))))

1.4.1 Indentation for new major-modes

Because most Emacs major-modes have their own indentation settings, this plugin requires explicit support for each major-mode for indent_size property.

By default this plugin ships with settings for many major-modes, but, sorry to say, it cannot be perfect. Especially it is difficult to support brand-new major-modes. Please feel free to submit issue or pull-request for such major-mode!

Supported major-modes and their indentation configs are defined in the variable editorconfig-indentation-alist.

1.4.2 Not work at all for FOO-mode!

Most cases properties are loaded just after visiting files when editorconfig-mode is enabled. But it is known that there are major-modes that this mechanism does not work for and require explicit call of editorconfig-apply.

Typically it will occur when the major-mode is not defined using define-derived-mode (rpm-spec-mode is an example for this). Please feel free to submit issues if you find such modes!

1.5.1 Development

Make and CMake must be installed to run the tests locally:

$ make check

To start a new Emacs process with current *.el and without loading user init file, run:

$ make sandbox
