NAME
----
options - a

Types
-----
*int*::
	an integer number
*bool*::
	a boolean value, yes/true or no/false
*str*::
	a string, some freeform text
*coord*::
	a line, column pair (separated by comma)
*regex*::
	as a string but the set commands will complain if the entered text
	is not a valid regex
*int-list*, *str-list*::
	a list, elements are separated by a colon (:) if an element needs
	to contain a colon, it can be escaped
	with a backslash
*range-faces*::
	a `:` separated list of a pairs of a buffer range
	(`<begin line>.<begin column>,<end line>.<end column>`) and  a face
	(separated by `|`), except for the first element which is just the
	timestamp of the buffer.
*completions*::
	a `:` separated list of `<text>|<docstring>|<menu text>`
	candidates, except for the first element which follows the
	`<line>.<column>[+<length>]@<timestamp>` format to define where the
	completion apply in the buffer.
*enum(value1|value2|...)*::
	an enum, taking one of the given values
*flags(value1|value2|...)*::
	a set of flags, taking a combination of the given values joined by a
	'|' character

Scopes
------
*window*::
	context linked to the window displaying a buffer
*buffer*::
	context linked directly to the buffer
*global*::
	global context linked to the instance of Kakoune

Options can have individual values that change from one scope to the other,
which will be considered one after another in the following order: *window*
→  *buffer* →  *global*.  That means that two windows on the same buffer
can use different options (e.g. different *filetype*).  However some options
might end up being ignored if their scope is not in the command context.
For example, writing a file never uses the *window* scope when considering
options, so any option related to writing won't be taken into account if
set in the *window* scope (e.g. *BOM*, *eolformat*).

Builtin options
---------------

*tabstop* 'int'::
	width of a tab character

*indentwidth* 'int'::
	width (in spaces) used for indentation, 0 means a tab character

*scrolloff* 'coord'::
	number of lines, columns to keep visible around the cursor when
	scrolling

*eolformat* 'enum(lf|crlf)'::
	the format of end of lines when writing a buffer, this is autodetected
	on load

*BOM* 'enum(none|utf8)'::
	define if the file should be written with an unicode byte order mark

*readonly* 'bool'::
	prevent modifications from being saved to disk, all
	buffers if set to `true` in the `global` scope, or current buffer if set in
	the `buffer` scope.

*incsearch* 'bool'::
	execute search as it is typed

*aligntab* 'bool'::
	use tabs for alignment command

*autoinfo* 'flags(command|onkey|normal)'::
	display automatic information box in the enabled contexts

*autoshowcompl* 'bool'::
	automatically display possible completions when editing a prompt

*ignored_files* 'regex'::
	filenames matching this regex wont be considered as candidates on
	filename completion (except if the text being completed already
	matches it)

*disabled_hooks* 'regex'::
	hooks whose group matches this regex wont be executed. For example
	indentation hooks can be disabled with '.*-indent'

*filetype* 'str'::
	arbitrary string defining the type of the file filetype dependant
	actions should hook on this option changing for activation/deactivation

*path* 'str-list'::
	directories to search for gf command

*completers* 'str-list'::
	completion engines to use for insert mode completion (they are tried
	in order until one generates candidates). Existing completers are:

	*word=all*, *word=buffer*:::
		which complete using words in all buffers (*word=all*)
		or only the current one (*word=buffer*)

	*filename*:::
		which tries to detect when a filename is being entered and
		provides completion based on local filesystem

	*option=<opt-name>*:::
		where *opt-name* is a 'completions' option.

*static_words* 'str-list'::
	list of words that are always added to completion candidates
	when completing words in insert mode

*completions_extra_word_chars* 'str'::
	a string containing all additional character that should be considered
	as word character for the purpose of insert mode completion.

*autoreload* 'enum(yes|no|ask)'::
	auto reload the buffers when an external modification is detected

*debug* 'flags(hooks|shell|profile)'::
	dump various debug information in the '\*debug*' buffer

*modelinefmt* 'string'::
	A format string used to generate the mode line, that string is first
	expanded as a command line would be (expanding '%...{...}' strings),
	then markup tags are applied (c.f. the 'Expansions' documentation page)

*ui_options*::
	colon separated list of key=value pairs that are forwarded to the user
	interface implementation. The NCurses UI support the following options:

		*ncurses_set_title*:::
			if *yes* or *true*, the terminal emulator title will
			be changed

		*ncurses_status_on_top*:::
			if *yes*, or *true* the status line will be placed
			at the top of the terminal rather than at the bottom

		*ncurses_assistant*:::
			specify the nice assistant you get in info boxes,
			can be *clippy* (the default), *cat* or *none*

		*ncurses_wheel_down_button*, *ncurses_wheel_up_button*:::
			specify which button send for wheel down/up events
