Class: RuboCop::Cop::Lint::ConstantResolution
- Defined in:
- lib/rubocop/cop/lint/constant_resolution.rb
Overview
Check that certain constants are fully qualified.
This is not enabled by default because it would mark a lot of offenses unnecessarily.
Generally, gems should fully qualify all constants to avoid conflicts with
the code that uses the gem. Enable this cop without using Only
/Ignore
Large projects will over time end up with one or two constant names that
are problematic because of a conflict with a library or just internally
using the same name a namespace and a class. To avoid too many unnecessary
offenses, Enable this cop with Only: [The, Constant, Names, Causing, Issues]
Note
|
Style/RedundantConstantBase cop is disabled if this cop is enabled to prevent
conflicting rules. Because it respects user configurations that want to enable
this cop which is disabled by default.
