In General

You can get the built files from the release branch. If you have specific instructions for your editor, PR's are welcome.

Dynamic Injection

Thanks to content node of tree-sitter-embedded-template grammar, dynamic injections can be attached to template body.

File name pattern convention

To make it easier to understand which parser will be injected and which filetype is used in template body, the following pattern is recommended to implement this grammar:

<file-name>.(ext).hygen

Tree-sitter predicate/directive

To implement dynamic injection, is recommended to create a predicate/directive with the following name:

#inject-hygen-tmpl!

[!NOTE] The creation of this predicate/directive varies for each editor
