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

= Scopes
|
|
|
|
== Description
|
|
|
|
Scopes are groups in which a particular Kakoune object (a variable,
|
|
hook, alias etc) can have different values, depending on the group the
|
|
value was declared in.
|
|
|
|
== Names and hierarchy
|
|
|
|
Scopes are named as follows:
|
|
|
|
*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
|
|
|
|
The following order of priority applies to the above scopes:
|
|
|
|
--------------------------
|
|
window ]> buffer ]> global
|
|
--------------------------
|
|
|
|
The above priority line implies that objects can have individual values that
|
|
will be resolved first in the *window* scope (highest priority), then in
|
|
the *buffer* scope, and finally in the *global* scope (lowest priority).
|
|
|
|
== Uses
|
|
|
|
The scope paradigm is very useful as it allows the user to customize the
|
|
behavior of the editor without modifying the configuration globally, as
|
|
is the case with other editors who only have a single *global* scope by
|
|
default.
|
|
|
|
Examples:
|
|
|
|
*filetype*::
|
|
A single buffer opened in two separate windows can have different
|
|
filetypes declared in the *window* scope with 'set' (c.f. the 'options'
|
|
documentation page)
|
|
|
|
*status line*::
|
|
All the buffers of the current session can have the same information
|
|
displayed in the status line, except for a specific buffer (the
|
|
'modelinefmt' option can be declared in the *global* scope, and
|
|
customized in the *buffer* scope with 'set', c.f. the 'options'
|
|
documentation page)
|
|
|
|
== Execution context
|
|
|
|
Some commands work in a specific context that might exclude one or
|
|
several scopes altogether, consequently ignoring some values of a given
|
|
object.
|
|
|
|
Example: the *window* scope is never considered when resolving the
|
|
values of options when writing a buffer (e.g. 'BOM', 'eolformat').
