#7942 `regex-lint` (formerly `validate`) should allow path blocklisting Issue created by jsirois Right now, content checks are restricted to path sets built up from path allow lists. Often it would be more robust to apply a content check to all files of a certain type save some small handfull. For those cases adding to a blocklist is both more concise and robust than enumerating allow listed directories. Concretely, this sort of config today: x-path-pattern: &path-pattern content_encoding: utf8 path_patterns: # We use several python path patterns here to avoid src/python/kythe which contains 3rdparty code # that we don't have license over (python proto stubs for kythe-licensed protobuf files). python_prod: <<: *path-pattern pattern: prod/.+(?<!init)\.py$ python_source: <<: *path-pattern pattern: src/python/toolchain/.+(?<!init)\.py$ python_test: <<: *path-pattern pattern: test/.+(?<!init)\.py$ content_patterns: python_header: # NB: We match an optional shebang line here. pattern: |- ^(#![^\n]+ )?# Copyright © 20\d\d Toolchain Labs, Inc\.
