@teacss/language-service

Transport-neutral TeaCSS editor intelligence.

Use it for an in-process editor, playground, or tool. It returns vscode-languageserver-types data and does not own an LSP connection.

import { TeacssLanguageService } from "@teacss/language-service";

const service = new TeacssLanguageService({ rootPath: process.cwd() });
await service.ready;

await service.getHover(document, { line: 0, character: 13 });
await service.getSemanticTokens(document);
await service.getClassNameEdits(document);

service.contextManager.releaseDocument(filePath);

The service provides completion, hover, colors, references, diagnostics, Quick Fixes, semantic tokens, and canonical class edits. References use the active entry's @source graph. Class edits preserve unknown classes.

DOM context attributes (lang, the seven data-css-<role> attributes, data-css-appearance, data-css-group, and data-css-peer) contain values, not class usages. Their values, including JSX and Vue bindings, are excluded from utility intelligence. Class tokens such as p:4@lang-zh retain completion, hover, references, and highlighting. Generic data-theme, data-mode, data-group, and data-peer have no special TeaCSS context handling.

Use contextManager.setRoots(roots) to replace workspace roots; [] unloads all contexts. Release a document or call reload() when a nearer entry becomes available after the document was cached.

@teacss/language-server adds LSP transport and watchers. @teacss/vscode provides the ready-made VS Code extension.

Pre-1.0. Results follow the active CSS entry.
