the re module <https://docs.python.org/3/library/re.html>`_.
Path prefix, selector `pp:`
This pattern style is useful to match whole sub-directories. The pattern
`pp:root/somedir` matches `root/somedir` and everything therein. A leading
path separator is always removed.
This pattern style matches either the whole path or an initial segment
of the path up to but not including a path separator. For consistency
with the `fn:` and `sh:` patterns, a path separator is added to the
end of the path before matching. For example, `pp:root/somedir`
matches `root/somedir` and everything therein. A leading path
separator is always removed. A trailing slash makes no difference.
Path full-match, selector `pf:`
This pattern style is (only) useful to match full paths.
This pattern style is (only) useful to match full (exact) paths.
This is kind of a pseudo pattern as it can not have any variable or
unspecified parts - the full path must be given. `pf:root/file.ext` matches
`root/file.ext` only. A leading path separator is always removed.
