@ -848,25 +848,14 @@ The value of this variable is a regexp matching the node type of defun
nodes. (For ``node'' and ``node type'', @pxref{Parsing Program Source}.)
For example, @code{python-mode} sets this variable to a regexp that
matches either @code{function_definition} or @code{class_definition}.
matches either @code{"function_definition"} or @code{"class_definition"}.
@end defvar
@defvar treesit-defun-prefer-top-level
If this variable is non-@code{nil}, Emacs skips nested defuns, when it
looks for beginning and end of a defun, and prefers to go to the
top-level defun instead.
In some languages, a defun could be nested in another one. By default,
Emacs stops at the first defun it encounters. But if this variable's
value is @code{t}, whenever Emacs finds a defun node, it tries to go
up the parse tree until it finds the top-level defun.
This variable can also be a list of cons cells of the form
@w{@code{(@var{from} . @var{to}))}}, where @var{from} and @var{to} are
regexps matching tree-sitter node types. When Emacs finds a defun
node whose type matches any of the @var{from} regexps in the list, it
then tries to go up the parse tree until it finds a higher-level node
matching the corresponding @var{to} regexp.
@defvar treesit-defun-tactic
This variable determines how does Emacs treat nested defuns. If the
value is @code{top-level}, navigation functions only move across
top-level defuns, if the value is @code{nested}, navigation functions
recognize nested defuns.
