GH-72904: Add glob.translate() function (#106703)
Add `glob.translate()` function that converts a pathname with shell wildcards to a regular expression. The regular expression is used by pathlib to implement `match()` and `glob()`. This function differs from `fnmatch.translate()` in that wildcards do not match path separators by default, and that a `*` pattern segment matches precisely one path segment. When *recursive* is set to true, `**` pattern segments match any number of path segments, and `**` cannot appear outside its own segment. In pathlib, this change speeds up directory walking (because `_make_child_relpath()` does less work), makes path objects smaller (they don't need a `_lines` slot), and removes the need for some gnarly code.

|
|||
>>> glob.glob('.c*')
|
||||
['.card.gif']
|
||||
|
||||
|
||||
.. function:: translate(pathname, *, recursive=False, include_hidden=False, seps=None)
|
||||
|
||||
Convert the given path specification to a regular expression for use with
|
||||
:func:`re.match`. The path specification can contain shell-style wildcards.
|
||||
|
||||
For example:
|
||||
|
||||
>>> import glob, re
|
||||
>>>
|
||||
>>> regex = glob.translate('**/*.txt', recursive=True, include_hidden=True)
|
||||
>>> regex
|
||||
'(?s:(?:.+/)?[^/]*\\.txt)\\Z'
|
||||
>>> reobj = re.compile(regex)
|
||||
>>> reobj.match('foo/bar/baz.txt')
|
||||
<re.Match object; span=(0, 15), match='foo/bar/baz.txt'>
|
||||
|
||||
Path separators and segments are meaningful to this function, unlike
|
||||
:func:`fnmatch.translate`. By default wildcards do not match path
|
||||
separators, and ``*`` pattern segments match precisely one path segment.
|
||||
|
||||
If *recursive* is true, the pattern segment "``**``" will match any number
|
||||
of path segments. If "``**``" occurs in any position other than a full
|
||||
pattern segment, :exc:`ValueError` is raised.
|
||||
|
||||
If *include_hidden* is true, wildcards can match path segments that start
|
||||
with a dot (``.``).
|
||||
|
||||
A sequence of path separators may be supplied to the *seps* argument. If
|
||||
not given, :data:`os.sep` and :data:`~os.altsep` (if available) are used.
|
||||
|
||||
.. seealso::
|
||||
|
||||
:meth:`pathlib.PurePath.match` and :meth:`pathlib.Path.glob` methods,
|
||||
which call this function to implement pattern matching and globbing.
