Verruca Vulgaris Treatments for Scala
summary
WartRemover is a linter that runs as a compiler plugin, macro, or command line tool to find and error on specific Scala “warts.” It disables features by introducing ambiguous implicits (examples: any2stringadd, postfix ops) and can ban calls like println or Option.get by traversing the Scala AST and checking predef symbols. About 25,000 lines of inherited code were deleted, leaving ~15,000 with a goal of ~10,000; current limits are false positives/negatives, lack of region suppression, and not yet ready to run over the whole codebase.
