VSCode Ember Syntax

Syntax highlighting for Ember template files AND syntax highlighting for inline template definitions with tagged templates! The package currently includes patterns matching htmlbars syntax only, but patterns for the new Glimmer components are on the way.

Inline Templates

It is currently possible to define your component templates in the component files using the layout property and the htmlbars-inline-precompile tool. Welcome to single file component definitions!

Emmet

Emmet will not work with this extension without configuration (The handlebars language id used by this extension does not activate the Emmet extension tab completions).

The "emmet.syntaxProfiles" inside your preferences can be used to notify Emmet to include handlebars in the list of respected syntaxes:

// settings.json
{
  "emmet.syntaxProfiles": { "handlebars": "html" }
}

You can also configure Emmet to complete using single quotes:

// settings.json
{
  "emmet.syntaxProfiles": {
    "handlebars": "html",
    "html": {
      "attr_quotes": "single"
    }
  }
}

_See the Emmet syntaxProfiles docs for syntaxProfiles details. See the HTML Language docs for VSCode preferences details._

Contributing

Contributions are welcome! Notes below are intended to help contributers become familiar with the repo.

Grammar Sources: Grammar files are built in the glimmer-syntax-patterns repository, any updates or issues with the grammar patterns should be submitted there. All VSCode specific configurations are handled in this repository.

Embedded Language: VSCode must be notified when a language is embedded into another language. This is done in the package.json grammars configs. This is how the editor knows to insert Handlebars scoped comments and snippets inside tagged templates in JS files.
