v0.1.2

This release aligns the extension with the approach used by Antlers Toolbox: .antlers.html is treated as HTML instead of a separate language, so you get full HTML behavior (validation, IntelliSense, Emmet) by default. It also makes this extension the single source of CSS validation for HTML when the built-in validator is off.

Highlights

• Extend HTML instead of a separate language — Contributes .antlers.html and .antlers.htm to the built-in HTML language and registers a grammar for html that adds Antlers syntax. No files.associations needed; .antlers.html is HTML with Antlers highlighting.
• No duplicate CSS errors — Sets the default html.validate.styles to false so the built-in validator doesn’t report false “identifier expected” / “} expected” on #{{ 'module-' + id }} and similar. This extension then validates <style> for all HTML.
• Style validation for all HTML — Validates CSS inside <style> in every HTML document: Antlers-aware for .antlers.html (strips {{ ... }} then validates), standard for plain .html / .htm (validates as-is). One extension handles both.
• Coexistence with Antlers Toolbox — Safe to use alongside Stillat’s extension; both contribute to the same HTML language. Only one grammar applies (by load order).

Breaking change

• .antlers.html is now HTML — The previous “Antlers” language id is no longer used. If you had "files.associations": { "**/*.antlers.html": "antlers" }, you can remove it.

Upgrade

After installing v0.1.2, reload the window. If you still see duplicate CSS diagnostics in .antlers.html, ensure html.validate.styles is not overridden to true in your settings.
