@cssdoc/index

A queryable semantic index over the @cssdoc/core model — the shared data layer every cssdoc linter and the language server query. It adds the two cross-cutting concerns those tools need:

• a host-agnostic Usage abstraction (ClassUsage, PropertyUsage) so HTML, JSX, template literals, and CSS selectors all feed the same providers; and
• optional source spans, built in a dedicated PostCSS pass (so @cssdoc/core stays position-free), powering diagnostics locations, hover ranges, and go-to-definition.

Usage

import { createIndex } from "@cssdoc/index";

const index = createIndex(css, { file: "components.css" });
index.componentForClass(".button"); // → the button record
index.isModifier(".button", "-color-x"); // → boolean
index.deprecationOf(".button", "-old"); // → { canonical } | undefined
index.location("button", "modifier:-color-secondary"); // → { file, span } | undefined

createIndex(css) includes spans; indexFromEntries(entries) builds a lookup-only index from a model snapshot (index.toManifest()), without spans.
