npm install @asterql/formatter

Deterministic formatting and canonical AST serialization for AsterQL.

import { canonicalize, format } from "@asterql/formatter";

format('*.posts[status="published"]|sort(-date)[:10] {id,title}');
// *.posts[status == "published"]
// | sort(-date)[:10] {id, title}

canonicalize('*.posts[status="published"]');
// Span-free JSON over the parsed AST.

API

format(queryOrAst, { printWidth?: number }): string
canonicalAst(queryOrAst): CanonicalAst
canonicalize(queryOrAst): string
serializeCanonicalAst(queryOrAst): string

Formatting is parse-backed and idempotent. Canonicalization is intentionally separate from formatting so future view hashes do not depend on whitespace or stylistic source text.
