==========

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
*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

*complete_prefix* 'bool'::
	when completing in command line, and multiple candidates exist, enable completion with common prefix

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

*aligntab* 'bool'::
	use tabs for alignement 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 'str-list' option. The first element of the list should follow the format:

			<line>.<column>[+<length>]@<timestamp>

		to define where the completion apply in the buffer, and the other strings are the candidates

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

*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
