Module: SimpleCov::StaticCoverageExtractor::PrismCompat

Defined in:

Overview

The Prism 1.3 accessor renames for the trailing clause of conditional nodes, resolved once at load so the per-node hot paths stay branch-free. Ruby 3.3's stdlib Prism predates the renames; 3.4+ and any installed prism gem post-date them, and reaching for the modern name on the old one raised NoMethodError inside the extractor, which call swallowed, silently falling back to no simulated data.

This lives in its own file, required by every consumer, because the constants are referenced from several extractor files and defining them after those files were loaded worked only while the references happened at call time: a load-order trap for the next editor.

Instance Method Details

#else_clause(node) ⇒ Object

The rename hit UnlessNode, CaseNode, and CaseMatchNode together, so one constant probed off CaseNode covers all three.
