Module: SimpleCov::SourceFile::BuilderContext

Included in:

SimpleCov::SourceFile

Defined in:

lib/simplecov/source_file/builder_context.rb

Overview

Helpers shared by the per-criterion builders (LineBuilder / BranchBuilder / MethodBuilder). Mixed into SourceFile so each builder can ask the file for its skip-chunk ranges and Prism-derived real source positions without duplicating the memoization.

Instance Method Summary

• #real_source_positions ⇒ Object

  Memoized set of real source positions (branch start lines, method name+line pairs) extracted via Prism.

• #skip_chunks_for(criterion) ⇒ Object

  Skip-chunk lookup for the named criterion (‘:line`, `:branch`, `:method`).

Instance Method Details

#real_source_positions ⇒ Object

Memoized set of real source positions (branch start lines, method name+line pairs) extracted via Prism. Returns nil when Prism is unavailable or parsing fails, signaling callers to keep every Coverage entry (no false drops). The ‘defined?` guard preserves a nil memoization across calls.

# File 'lib/simplecov/source_file/builder_context.rb', line 21

def real_source_positions
  return @real_source_positions if defined?(@real_source_positions)

  @real_source_positions = StaticCoverageExtractor.real_source_positions(src.join)
end

#skip_chunks_for(criterion) ⇒ Object

Skip-chunk lookup for the named criterion (‘:line`, `:branch`, `:method`).
