描述

Describe the Bug

When the lang attribute of the <style> tag is not on the same line as the style tag, the content may be incorrectly highlighted as CSS syntax.

Steps to Reproduce

  1. npm create astro@latest
  2. open the project in vscode
  3. install newest astro extension
  4. create anyname.astro with the contents
<style
  lang="sass"
  define:vars={{
    // any comment to avoid formatter collapse content into a single line
    foo: '#fff',
  }}
>
  .bar
    color: var(--foo)
</style>
  1. the content below .bar (include </style>) will be incorrectly highlighted as css syntax, not sass.

研究方向
The bug is in the Astro VSCode extension's TextMate grammar for style tags. The grammar currently assumes the lang attribute is on the same line as the opening <style tag. To fix, update the grammar to handle multiline attributes by using a pattern that allows newlines between <style and the attribute. Look at the syntaxes/astro.tmLanguage.json file in the withastro/language tools repository. Test the provided example to ensure SASS content is correctly highlighted.
