RuboCop's severity levels are represented by
RuboCop::Cop::Severity
objects, not symbols. Internally, this objects holds a symbol in itsname
attribute an implements comparison methods.Sadly, these comparisons aren't reversable:
severity === :info => true
, but:info === severity => false
.The ruby case statement performs tripple-equals comparisons with the argument to the
when
clause as the first operand, so the existing case statement always returnedUNKNOWN_SEVERITY
.In addition to fixing the above issue, this PR adds mappings for the non-standard RuboCop
convention
andrefactor
severity levels toINFO
and calculates a top-levelseverity
value in the rdjson output based on RuboCop's configured fail level.Fixes #75
