I’ve just installed a new Discourse [theme component](https://github.com/discourse/discourse-highlightjs-glimmer) here which enables syntax highlighting for gjs (template-tag) files. To use it, tag your code fences with `gjs` like this:

````
```gjs
/* Code goes here */
```

````

For example:

```gjs
import WeatherSummary from './weather-summary.js';

const Greeting = <template>
  <p>Hello, {{@name}}!</p>
</template>;

function isBirthday(dateOfBirth) {
  const now = new Date();
  return (
    dateOfBirth.getDate() === now.getDate() &&
    dateOfBirth.getMonth() === now.getMonth()
  );
}

<template>
  <div>
    <Greeting @name="Chris" />
    {{#if (isBirthday @user.dateOfBirth)}}
      <Celebration type='birthday' />
    {{/if}}
    <WeatherSummary />
  </div>
</template>

```

Thanks to @NullVoxPopuli for the [highlightjs-glimmer package](https://github.com/NullVoxPopuli/highlightjs-glimmer) which we’re leaning on for this 🤩

I have some bugfixes to land in there that I’ve found while making a documentation system over at [https://ember-primitives.pages.dev/](https://ember-primitives.pages.dev/) 😅
