repathlib

repathlib is a package that combines repathlib and re, enabling you to search, match, etc., on Path objects, and to search directories with Path.reiterdir:

from repathlib import Path
docs = Path('docs')
docs.search('d[a-z]+')

<re.Match object; span=(0, 4), match='docs'>

list(docs.reiterdir('\.rst'))

[PosixPath('docs/api.rst'), PosixPath('docs/index.rst')]
