== 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.
|
|
|
|
[[set-option]]
|
|
Options can be modified using the `set-option` command:
|
|
|
|
--------------------------------------------
|
|
set-option [-add] <scope> <name> <values>...
|
|
--------------------------------------------
|
|
|
|
<scope> can be *global*, *buffer*, *window* or *current* (See
|
|
<<scopes#,`:doc scopes`>>). *current* relates to the narrowest scope in
|
|
which the option is already set.
|
|
|
|
Multiple <values> can be given as separate arguments when the option is a
|
|
list or map.
|
|
|
|
If `-add` is specified, the new value is *added* to the current one
|
|
instead of replacing it (the exact outcome depends on the type, see below).
|
|
|
|
[[unset-option]]
|
|
Options values can be unset in a specific scope with the `unset-option`
|
|
command:
|
|
|
|
---------------------------
|
|
unset-option <scope> <name>
|
|
---------------------------
|
|
|
|
Unsetting an option will make it fallback to the value of its parent mode,
|
|
hence options cannot be unset from the *global* scope.
|
|
|
|
[[declare-option]]
|
|
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.
|
|
|
|
[[update-option]]
|
|
Certain option type can be *updated*, usually to match potential changes
|
|
in the buffer they relate to. This can be triggered by the `update-option`
|
|
command:
|
|
|
|
----------------------------
|
|
update-option <scope> <name>
|
|
----------------------------
|
|
|
|
== 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.
|
|
`set -add` performs a math addition
|
|
|
|
*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 a comma)
|
|
|
|
*<type>-list*::
|
|
a list, elements are specified as separate arguments to the command.
|
|
`set -add` appends the new element to the list
|
|
|
|
*range-specs*::
|
|
a 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.
|
|
See <<highlighters#specs-highlighters,`:doc highlighters specs-highlighters`>>)
|
|
`set -add` appends the new pair to the list
|
|
|
|
*line-specs*::
|
|
a 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.
|
|
See <<highlighters#specs-highlighters,`:doc highlighters specs-highlighters`>>)
|
|
`set -add` appends the new spec to the list
|
|
|
|
*completions*::
|
|
a 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.
|
|
`set -add` adds a new completion to the list
|
|
|
|
*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.
|
|
`set -add` adds the new flag to the combination
|
|
|
|
*<type>-to-<type>-map*::
|
|
a list of `key=value` pairs.
|
|
`set -add` adds the new pair to the hashmap or replace an already
|
|
existing key.
|
|
|
|
