1. Filetypes *filetypes* *file-types*
Vim can detect the type of file that is edited. This is done by checking the
file name and sometimes by inspecting the contents of the file for specific
text.
*:filetype* *:filet*
To enable file type detection, use this command in your vimrc: >
:filetype on
Each time a new or existing file is edited, Vim will try to recognize the type
of the file and set the 'filetype' option. This will trigger the FileType
event, which can be used to set the syntax highlighting, set options, etc.
Detail: The ":filetype on" command will load these files:
$VIMRUNTIME/filetype.lua
$VIMRUNTIME/filetype.vim
filetype.lua creates an autocommand that fires for all BufNewFile and
BufRead events. It tries to detect the filetype based off of the
file's extension or name.
filetype.vim is a Vim script that defines autocommands for the
BufNewFile and BufRead events. In contrast to filetype.lua, this
file creates separate BufNewFile and BufRead events for each filetype
pattern.
If the file type is not found by the name, the file
$VIMRUNTIME/scripts.vim is used to detect it from the contents of the
file.
When the GUI is running or will start soon, the |menu.vim| script is
also sourced.
To add your own file types, see |new-filetype| below. To search for help on a
filetype prepend "ft-" and optionally append "-syntax", "-indent" or
"-plugin". For example: >
:help ft-vim-indent
:help ft-vim-syntax
:help ft-man-plugin
If the file type is not detected automatically, or it finds the wrong type,
you can either set the 'filetype' option manually, or add a modeline to your
file. Example, for an IDL file use the command: >
:set filetype=idl
or add this |modeline| to the file: >
/* vim: set filetype=idl : */
<
*:filetype-plugin-on*
You can enable loading the plugin files for specific file types with: >
:filetype plugin on
If filetype detection was not switched on yet, it will be as well.
This actually loads the file "ftplugin.vim" in 'runtimepath'.
The result is that when a file is edited its plugin file is loaded (if there
is one for the detected filetype). |filetype-plugin|
*:filetype-plugin-off*
You can disable it again with: >
:filetype plugin off
The filetype detection is not switched off then. But if you do switch off
filetype detection, the plugins will not be loaded either.
This actually loads the file "ftplugof.vim" in 'runtimepath'.
*:filetype-indent-on*
You can enable loading the indent file for specific file types with: >
:filetype indent on
If filetype detection was not switched on yet, it will be as well.
This actually loads the file "indent.vim" in 'runtimepath'.
The result is that when a file is edited its indent file is loaded (if there
is one for the detected filetype). |indent-expression|
*:filetype-indent-off*
You can disable it again with: >
:filetype indent off
The filetype detection is not switched off then. But if you do switch off
filetype detection, the indent files will not be loaded either.
This actually loads the file "indoff.vim" in 'runtimepath'.
This disables auto-indenting for files you will open. It will keep working in
already opened files. Reset 'autoindent', 'cindent', 'smartindent' and/or
'indentexpr' to disable indenting in an opened file.
*:filetype-off*
To disable file type detection, use this command: >
:filetype off
This will keep the flags for "plugin" and "indent", but since no file types
are being detected, they won't work until the next ":filetype on".
