module Analyzer::Specification::GraphqlTypedefs

Overview

Shared extractor for inline typeDefs template literals, used by the Apollo Server and GraphQL Yoga analyzers. Returns (SDL, line_offset) pairs — the SDL string carried by each typeDefs backtick template and the 0-based source line where it begins.

The whole scan runs over an Array(Char) rather than indexing the String directly. String#[](Int) is O(n) whenever the source is not single-byte-optimizable, so a single multi-byte char (an emoji in a JS comment or a """description""") would otherwise make the per-char template walk quadratic — ~6 s on a 120 KB file vs ~0.2 ms here.

Instance Method Summary

• #extract(content : String, skip_js_comments : Bool = false) : Array(Tuple(String, Int32))

  skip_js_comments skips /* GraphQL */ / // ... between the assignment and the value — Yoga idiomatically annotates the literal that way; Apollo does not, so it opts out.
