Parses date/times from a path given a glob pattern intertwined with date/time format akin to strptime/strftime format.
datetime.datetime.strptime suffices for simple date/time parsing. However, as soon as you need to handle wildcards,
it becomes tricky and you need to resort to regular expressions.
We found the glob patterns and strptime format to be far easier to read and write than regular expressions, and
encapsulated the logic involving regular expressions in this module.
Installation
============
* Create a virtual environment:
.. code-block:: bash
python3 -m venv venv3
* Activate it:
.. code-block:: bash
source venv3/bin/activate
* Install datetime-glob with pip:
.. code-block:: bash
pip3 install datetime-glob
Usage
=====
To match a path:
.. code-block:: python
>>> import datetime_glob
>>> matcher = datetime_glob.Matcher(pattern='/some/path/*%Y-%m-%dT%H-%M-%SZ.jpg')
>>> match = matcher.match(path='/some/path/some-text2016-07-03T21-22-23Z.jpg')
>>> match
datetime_glob.Match(year = 2016, month = 7, day = 3, hour = 21, minute = 22, second = 23)
>>> match.as_datetime()
datetime.datetime(2016, 7, 3, 21, 22, 23)
>>> match.as_date()
datetime.date(2016, 7, 3)
>>> match.as_time()
datetime.time(21, 22, 23)
If you specify a directive for the same field twice, the matcher will make sure that the field has the same semantical
value in order to match:
.. code-block:: python
>>> import datetime_glob
>>> matcher = datetime_glob.Matcher(pattern='/some/path/%y/%Y-%m-%d.txt')
>>> match = matcher.match(path='/some/path/16/2016-07-03.txt')
>>> match
datetime_glob.Match(year = 2016, month = 7, day = 3)
>>> match = matcher.match(path='/some/path/19/2016-07-03.txt')
>>> type(match)
<class 'NoneType'>
You can walk the pattern on the file system:
.. code-block:: python
import datetime_glob
for match, path in datetime_glob.walk(pattern='/some/path/*%Y/%m/%d/%H-%M-%SZ.jpg'):
dtime = match.as_datetime()
print(dtime, path)
2016-03-04 12:13:14 /some/path/saved-2016/03/04/12-13-14Z.jpg
2017-11-23 22:23:24 /some/path/restored-2017/11/23/22-23-24Z.jpg
To iterate manually over a tree, and match incrementally each path segment by yourself:
.. code-block:: python
>>> import datetime_glob
>>> pattern_segments = datetime_glob.parse_pattern(pattern='/some/path/*%Y/%m/%d/%H-%M-%SZ.jpg')
>>> match = datetime_glob.Match()
>>> match=datetime_glob.match_segment(segment='some', pattern_segment=pattern_segments[0], match=match)
>>> match
datetime_glob.Match()
>>> match=datetime_glob.match_segment(segment='path', pattern_segment=pattern_segments[1], match=match)
>>> match
datetime_glob.Match()
>>> match=datetime_glob.match_segment(segment='some-text2016', pattern_segment=pattern_segments[2], match=match)
>>> match
datetime_glob.Match(year = 2016)
>>> match=datetime_glob.match_segment(segment='07', pattern_segment=pattern_segments[3], match=match)
>>> match
datetime_glob.Match(year = 2016, month = 7)
>>> match=datetime_glob.match_segment(segment='03', pattern_segment=pattern_segments[4], match=match)
>>> match
datetime_glob.Match(year = 2016, month = 7, day = 3)
>>> match=datetime_glob.match_segment(segment='21-22-23Z.jpg', pattern_segment=pattern_segments[5], match=match)
>>> match
datetime_glob.Match(year = 2016, month = 7, day = 3, hour = 21, minute = 22, second = 23)
