Can't get Syntax Highlighting to work for Ruby in Emacs #154

Closed leviartan closed 2 years ago

leviartan commented 3 years ago

When I open a ruby file, I can see that Tree-Sitter-Hl mode is active, but none of the syntax highlighting has changed. But if I manually turn off it via M-X and then turn on again it start works. What am I doing wrong? How to force syntax highlighting automatically?

can you share your configuration, please?

Please note that tree-sitter-hl-mode:

Enabling this automatically enables tree-sitter-mode in the buffer.

To enable this automatically whenever tree-sitter-mode is enabled:

 (add-hook 'tree-sitter-after-on-hook #'tree-sitter-hl-mode)

so you should modify the entire code block of your tree-sitter configuration to:

(use-package tree-sitter
  :ensure t
  :config
  (add-hook 'tree-sitter-after-on-hook #'tree-sitter-hl-mode)
  (add-hook 'ruby-mode-hook #'tree-sitter-mode))

I use Doom Emacs as my basis for my configuration and I have emacs-tree-sitter configure like this.

Please make changes and test if things work.

Tried both variants, but sadly it doesn't work.

keep the configuration with those corrections, further investigation on the rest of it may be necessary
