.hbs) templates
Up-to-date sample highlighting can be found on the web page for this project here.
This package is already available as part of nvim-treesitter as the glimmer parser.
You can also follow these instructions to allow nvim-treesitter to use a locally-cloned version of this parser, which can be useful for development or trying out the most up-to-date highlighting.
