This is an EditorConfig plugin for Emacs.
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.
If you use use-package, add the following to your
init.el
file:
(use-package editorconfig
:ensure t
:config
(editorconfig-mode 1))
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)
Current Emacs plugin coverage for EditorConfig's properties:
indent_style
indent_size
tab_width
end_of_line
charset
trim_trailing_whitespace
insert_final_newline = true
is supportedis not enforced (as in trailing newlines actually being removed automagically), we just buffer-locally override any preferences that would auto-add them to filesinsert_final_newline = false

Not yet covered properties marked with over-strike

Typically, you will want to tie these to native functionality,
or the configuration of existing packages handling the feature.
As several packages have their own handling of, say, indentation, we might not yet cover some mode you use, but we try to add the ones that show up on our radar.
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.
editorconfig-emacs
provides some customize variables.
Here are some of these variables: for the full list of available variables, type M-x customize-group [RET] editorconfig [RET].
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)
(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)))
Enabling editorconfig-mode
should be enough for normal cases.
When EditorConfig properties are not effective for unknown reason, we recommend
first trying M-x editorconfig-display-current-properties
.
This command will open a new buffer and display the EditorConfig properties loaded for current buffer. You can check if EditorConfig properties were not read for buffers at all, or they were loaded but did not take effect for some other reasons.
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
.
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!
By default, lsp-mode configures indent-region-function so that Emacs uses
language servers' textDocument/rangeFormatting
request to format text in
buffers.
So EditorConfig settings are ignored unless language servers
themselves support loading configs from .editorconfig
.
To avoid this behavior ad-hocly, set lsp-enable-indentation
to nil.
Bugs, feature requests, and other issues should be submitted to the issue tracker: https://github.com/editorconfig/editorconfig-emacs/issues
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
