experimental

Headless editor intelligence for chartlang: diagnostics, completions, hover docs, signature help, definitions, and interval-aware suggestions.

Install

pnpm add @invinite-org/chartlang-language-service

Public surface

| Export | Purpose | |---|---| | createLanguageService(opts?) | Builds a capability-aware service instance. | | compileToDiagnostics(source) | Converts compiler diagnostics to LSP-style ranges. In browsers, inject opts.compileToDiagnostics so compilation runs outside the bundle. | | getCompletions(document, position) | Returns core symbols and interval completions. | | getHoverDoc(document, position) | Looks up generated hover docs from core JSDoc. | | getSignatureHelp(document, position) | Returns call signatures for known symbols. | | getDefinition(document, position) | Resolves generated source-location metadata. | | getAvailableIntervals() | Reads intervals from target capabilities. | | HOVER_REGISTRY | Checked-in generated hover-doc table. |

Dep-aware surfaces (Phase 0.7 indicator composition): hovers + completions for <binding>.output(...) and <binding>.withInputs({...}) resolve same-file producer titles and input schemas. The new dep-* compile diagnostics surface inline via compileToDiagnostics. Go-to-definition on .output("title") jumps to the producer's matching plot(value, { title }) call.

Minimum-viable API call

import { createLanguageService } from "@invinite-org/chartlang-language-service";

const service = createLanguageService({ targetCapabilities: capabilities });
const diagnostics = await service.compileToDiagnostics(source);
