** Disable syntax highlighting for certain modes
To disable syntax highlighting across the board you can do:
** Configuring Tree sitter highlighting
Highlighting is controlled by the variable =+tree-sitter-hl-enabled-modes=
This list allows you to whitelist, blacklist, fully enable or fully disable
tree-sitter highlighting for all major modes
To use highlighting in select modes add major-modes to
~+tree-sitter-hl-enabled-modes~. This disables highlighting in all other modes.
The symbol that should be used is the major mode symbol, *not the package
symbol*.
#+begin_src emacs-lisp
(remove-hook 'tree-sitter-after-on-hook #'tree-sitter-hl-mode)
(setq +tree-sitter-hl-enabled-modes '(python-mode go-mode))
#+end_src
Then it can be enabled for specific major modes:
If you want to disallow highlighting in certain modes then the car of
~+tree-sitter-hl-enabled-modes~ should be =not=. This enables highlighting in
all modes except the ones disallowed.
#+begin_src emacs-lisp
(add-hook 'MAJOR-MODE-hook #'tree-sitter-hl-mode)
(setq +tree-sitter-hl-enabled-modes '(not web-mode typescript-tsx-mode))
#+end_src
If ~+tree-sitter-hl-enabled-modes~ is set to ~nil~ or ~t~ it will fully disable
or fully enable highlighting in every tree sitter enabled language respectively.
