説明

Vimが認識できるファイルフォーマットのリスト。

例：

set fileformats=unix,dos
	This gives the end-of-line (<EOL>) formats that will be tried when
	starting to edit a new buffer and when reading a file into an existing
	buffer:
	- When empty, the format defined with 'fileformat' will be used
	  always.  It is not set automatically.
	- When set to one name, that format will be used whenever a new buffer
	  is opened.  'fileformat' is set accordingly for that buffer.  The
	  'fileformats' name will be used when a file is read into an existing
	  buffer, no matter what 'fileformat' for that buffer is set to.
	- When more than one name is present, separated by commas, automatic
	  <EOL> detection will be done when reading a file.  When starting to
	  edit a file, a check is done for the <EOL>:
	  1. If all lines end in <CR><NL>, and 'fileformats' includes "dos",
	     'fileformat' is set to "dos".
	  2. If a <NL> is found and 'fileformats' includes "unix", 'fileformat'
	     is set to "unix".  Note that when a <NL> is found without a
	     preceding <CR>, "unix" is preferred over "dos".
	  3. If 'fileformats' includes "mac", 'fileformat' is set to "mac".
	     This means that "mac" is only chosen when "unix" is not present,
	     or when no <NL> is found in the file, and when "dos" is not
	     present, or no <CR><NL> is present in the file.
	     Also if "unix" was first chosen, but the first <CR> is before
	     the first <NL> and there appears to be more <CR>'s than <NL>'s in
	     the file, then 'fileformat' is set to "mac".
	  4. If 'fileformat' is still not set, the first name from
	     'fileformats' is used.
	  When reading a file into an existing buffer, the same is done, but
	  this happens like 'fileformat' has been set appropriately for that
	  file only, the option is not changed.
	When 'binary' is set, the value of 'fileformats' is not used.

	For systems with a Dos-like <EOL> (<CR><NL>), when reading files that
	are ":source"ed and for vimrc files, automatic <EOL> detection may be
	done:
	- When 'fileformats' is empty, there is no automatic detection.  Dos
	  format will be used.
	- When 'fileformats' is set to one or more names, automatic detection
	  is done.  This is based on the first <NL> in the file: If there is a
	  <CR> in front of it, Dos format is used, otherwise Unix format is
	  used.
	Also see |file-formats|.
	For backwards compatibility: When this option is set to an empty
	string or one format (no comma is included), 'textauto' is reset,
	otherwise 'textauto' is set.
	NOTE: This option is set to the Vi default value when 'compatible' is
	set and to the Vim default value when 'compatible' is reset.
