Overview

Computes the set of line ranges that should be excluded from a SourceFile's coverage for each criterion. Two sources contribute:

  • The deprecated # :nocov: block toggle (lines wrapped between even-numbered pairs of nocov markers are excluded from line and branch coverage).
  • # simplecov:disable / # simplecov:enable block directives, which can be scoped per-criterion (# simplecov:disable branch, etc.) — see SimpleCov::Directive.

#for(criterion) ⇒ Object

Every criterion honors the deprecated all-criteria # :nocov: chunks plus its own per-criterion directive ranges. Methods included: they carry a source range, and nocov has always meant "exclude everything here".

  nocov_chunks + directive_chunks.fetch(criterion)
end

#nocov_chunks ⇒ Object

Ranges of 1-based line numbers (see with_index(1) below); consumers subtract 1 to index into the zero-based lines array.
