doc.kak now behaves as a basic asciidoc renderer. Asciidoc is unfortunately still a dependency to generate the manpage of the `kak` command.

== Description
|
|
|
|
Kakoune can store named and typed values that can be used both to customize
|
|
the core editor behaviour, and to store data used by extension scripts.
|
|
|
|
Options can be modified using the *set-option* command:
|
|
|
|
---------------------------------
|
|
set-option <scope> <name> <value>
|
|
---------------------------------
|
|
|
|
<scope> can be *global*, *buffer* or *window* (See <<scopes#,`:doc scopes`>>)
|
|
|
|
New options can be declared using the *declare-option* command:
|
|
|
|
------------------------------------------------
|
|
declare-option [-hidden] <type> <name> [<value>]
|
|
------------------------------------------------
|
|
|
|
If `-hidden` is specified, the option will not be displayed in completion
|
|
suggestions.
|
|
|
|
== Types
|
|
|
|
All options have a type, which defines how they are translated to/from text
|
|
and their set of valid values.
|
|
|
|
Some types are usable for user defined options while some other types
|
|
are exclusively available to built-in options.
|
|
|
|
*int*::
|
|
an integer number
|
|
*bool*::
|
|
a boolean value, yes/true or no/false
|
|
*str*::
|
|
a string, some freeform text
|
|
*regex*::
|
|
as a string but the set commands will complain if the entered text
|
|
is not a valid regex
|
|
*coord*::
|
|
a line, column pair (separated by comma)
|
|
*<type>-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-specs*::
|
|
a `:` separated list of a pair of a buffer range (`<begin
|
|
line>.<begin column>,<end line>.<end column>` or `<begin
|
|
line>.<begin column>+<length>`) and a string (separated by `|`),
|
|
except for the first element which is just the timestamp of
|
|
the buffer. When the `update-option` is used on an option of
|
|
this type, its ranges gets updated according to all the buffer
|
|
modifications that happened since its timestamp.
|
|
*line-specs*::
|
|
a `:` separated list of a line number and a corresponding flag
|
|
(`<line>|<flag text>`), except for the first element which is
|
|
just the timestamp of the buffer. When the `update-option` is
|
|
used on an option of this type, its lines gets updated according
|
|
to all the buffer modifications that happened since its timestamp.
|
|
*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. Markup can be used in the menu text.
|
|
*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
