Editor support

Language server

Masque ships a language server that speaks LSP over stdio. Any LSP-capable editor can use it.

cargo install --git https://github.com/fian-team/masque masque-lsp

It currently provides:

• Diagnostics from the scanner, the parser, and typed-binding validation
• Hover
• Go to definition
• Document symbols
• Semantic tokens

Completion, find references and rename are not implemented yet.

VS Code

The extension in the repository's editors/vscode folder adds syntax highlighting and connects to the language server. Set masque.lspPath if masque-lsp is not on your PATH.

TODO: publish the extension to the VS Code Marketplace and Open VSX.

Vocabulary scanner

masque-vocab scans documents for style keys and values that Masque would silently ignore:

masque-vocab ui/*.masque

Run it in CI, or assert on widget::vocabulary::scan_source from a test.
