Module: Munola::ProvidersConfig

Defined in:
lib/munola/providers_config.rb

Overview

Every munola project runs both Ruby providers by default: Prism through the script the enola gem carries, Rubydex built into the binary. The config is written once, never rewritten; the Rubydex library is fetched after the binary, and a fetch that fails is a named skip, never a silent absence.
