# Intended to include (lint) all headers except:
# ... those in ../../gen (generated files don't need to follow clang tidy)
# ... those in flutter/third_party (we didn't author this code, it's a dep)
#
# Unfortunately Clang Tidy uses an ancient version of regular expressions
# without lookaheads, so the next best thing is to write out every directory
# except third_party.
#
# If we ever add a new root directory, we'll have to update this expression.
#
# See the test in ./tools/clang_tidy/test/header_filter_regex_test.dart which
# should theoretically catch if new directories are added but this regex is not
# updated.
#
# tl;dr: I'm sorry.
