@ -103,6 +103,36 @@ collections of snippets automatically apply to the new Tree-Sitter modes.
Note that those modes still do not inherit from the non-TS mode, so
configuration settings installed via mode hooks are not affected.
Loading a Tree-Sitter mode (such as by using 'M-x load-library' or with
'M-x load-file') by default causes the corresponding non-Tree-Sitter
mode be remapped to the Tree-Sitter mode. This remapping affects
visiting files for which 'auto-mode-alist' specifies a non-Tree-Sitter
mode, and also affects mode-specification cookies on the first line of a
file and mode specifications in file- and directory-local variables. To
revert to using a non-Tree-Sitter mode, reload the corresponding mode
file anew. To prevent file loading from turning on Tree-Sitter mode
when 'auto-mode-alist' or the file/directory-local variables specify a
non-Tree-Sitter mode, customize the user option 'major-mode-remap-alist'
to specify that a non-Tree-Sitter mode is "remapped" to itself. For
example:
(add-to-list 'major-mode-remap-alist '(c-mode))
specifies that C Mode should not be remapped to 'c-ts-mode' even if and
when 'c-ts-mode' is loaded. Conversely,
(add-to-list 'major-mode-remap-alist '(c-mode . c-ts-mode))
tells Emacs to always invoke 'c-ts-mode' whenever 'c-mode' is
requested, either by 'auto-mode-alist' or by file/directory-local
variables.
We recommend using 'major-mode-remap-alist' to express your preferences
for using Tree-Sitter or non-Tree-Sitter modes for files for which both
variants of major modes are available, because that variable overrides
the remapping Emacs might decide to perform as result of loading Lisp
files and features.
