Module: RuboCop::Cop::ProjectIndexHelp

Included in:
Lint::ConstantReassignment
Defined in:
lib/rubocop/cop/mixin/project_index_help.rb

Overview

Common helpers for cops that consult the project-wide static-analysis index via ‘Cop::Base#project_index`.

Mixed-in cops gain the ‘external_dependency_checksum` override that invalidates the `ResultCache` whenever the indexed project files change on disk. To run index-backed analysis, cops should simply check whether `project_index` is non-nil; the runner only exposes a non-nil index when the user opted in via `AllCops/UseProjectIndex` and the underlying gem is available.
