The EditorConfig standard is an alternative to the .dir-locals.el files, which can control only a very small number of variables, but has the advantage of being editor-neutral, not specific to Emacs. Those settings are stored in files named .editorconfig, and affect the files in that directory and its subdirectories.
If you want Emacs to obey the settings from .editorconfig files, you
need to enable the editorconfig-mode
global minor mode. This is
usually all that is needed: when the mode is activated, whenever a file is
visited, Emacs will look for .editorconfig in the file’s directory
and its parent directories, just as it does for .dir-locals.el. When
both .editorconfig and .dir-locals.el files are found, their
settings are combined, and in case of a conflict, the setting coming from
the file closest in the directory hierarchy takes precedence. If they are
equally close, .dir-locals.el takes precedence. In terms of
security, the .editorconfig settings are subject to the same checks
as those coming from .dir-locals.el and from file-local variables
(and also honor enable-local-variables
). See 安全なファイル変数.
The indent_size
setting of the EditorConfig standard does not
correspond to a fixed variable in Emacs, but instead needs to set different
variables depending on the major mode. Ideally all major modes should set
the corresponding editorconfig-indent-size-vars
, but if you use a
major mode in which indent_size
does not take effect because the
major mode does not yet support it, you can customize the
editorconfig-indentation-alist
variable to tell Emacs which variables
need to be set in that major mode.
Similarly, there are several different ways to trim whitespace at the end of
lines. When the EditorConfig trim_trailing_whitespace
setting is
used, by default editorconfig-mode
simply calls
delete-trailing-whitespace
(see 不要なスペース) every time
you save your file. If you prefer some other behavior, you can customize
editorconfig-trim-whitespaces-mode
to the minor mode of your
preference, such as ws-butler-mode
.
