Troubleshooting

§1 Syntax Definition Parse Errors

Astro extends Sublime Text's HTML and Markdown syntax definitions.

If Astro syntax highlighting doesn't work and console displays syntax errors in HTML (Astro).sublime-syntax or Markdown (Astro).sublime-syntax, please make sure to remove any out-dated syntax override.

Steps:

1. call Menu > Preferences > Browse Packages..
2. Look for HTML and Markdown folders
3. Remove them or at least delete any syntax definition in them.

§2 Frontmatter or Components are not highlighted

Astro includes TypeScript (source.ts) and TSX (source.tsx) syntaxes to render Components.

Make sure to remove out-dated TypeScript or TSX syntax packages, which don't meet least compatibility requirements.

They can be identified by calling sublime.find_syntax_by_scope("source.ts") in ST's console.

Known candidates are:

• TypeScript
• TypeScript Syntax
