Reproduction steps
- Add these to Zed's
settings.json to use vscode-html-language-server instead of prettier for HTML formatting
{
"languages": {
"HTML": {
"formatter": "language_server",
"language_servers": ["vscode-html-language-server", "!prettier", "..."]
}
}
}
- You may need to restart Zed. Not sure.
- Open an html file having
<style> tags or style attributes. Sample code:
<!doctype html>
<html lang="en">
<body>
<input type="radio" name="" id="" style="" />
</body>
</html>
- Go to Language Servers(
Ctrl+Alt+L) in the bottom toolbar and ensure vscode-html-language-server is running. If it's not, saving the settings file seems to force it to load.
- Make some edits to the code
- In the command palette, run
dev: open language server logs and select vscode-html-language-server in the dropdown.
- Search for
Error
Current vs. Expected behavior
