Module: Herb::Embedded::ResultEnvelope

Defined in:
lib/herb/embedded/result_envelope.rb

Overview

Herb::ParseResult#to_json returns an inspect string, not the wire format @herb-tools/core's ParseResult.from() expects. This builds that envelope by hand from the pieces that do serialize correctly.

FORWARDABLE_OPTIONS =

Allowlist of Herb::ParserOptions keys safe to forward from caller-supplied options. Deliberately excludes prism_nodes, prism_nodes_deep, and prism_program: asking Herb.parse itself to embed prism_node populates it with a raw ASCII-8BIT String, and forwarding that through raises JSON::GeneratorError. Both are instead handled below by computing JSON-safe byte arrays ourselves. Also excludes timeout and max_errors (timing/error-cap options, not shape).
