parsedatetime
Parse human-readable date/time strings.
Python 2.7 or greater is required for parsedatetime version 1.0 or greater.
You can install parsedatetime using:
pip install parsedatetime
From the source directory:
python run_tests.py parsedatetime
To run tests on several python versions, type tox
:
$ tox [... tox creates a virtualenv for every python version and runs tests inside of each] py27: commands succeeded py33: commands succeeded py34: commands succeeded
This assumes that you have python2.7
, python3.4
, etc in PATH
.
An example of how to use parsedatetime:
import parsedatetime cal = parsedatetime.Calendar() cal.parse("tomorrow")
To get it to a Python datetime
object:
from datetime import datetime from time import mktime time_struct, parse_status = cal.parse("tomorrow") datetime.fromtimestamp(mktime(time_struct))
More detailed examples can be found in the examples directory.
The generated documentation is included by default in the docs directory and can also be viewed online at https://bear.im/code/parsedatetime/docs/index.html
The docs can be generated using either of the two commands:
python setup.py doc epydoc --html --config epydoc.conf
The Calendar
class has a member property named ptc
which is created during the class init method to be an instance
of parsedatetime_consts.CalendarConstants()
.
The code in parsedatetime has been implemented over the years in many different languages (C, Clipper, Delphi) as part of different custom/proprietary systems I've worked on. Sadly the previous code is not "open" in any sense of that word.
When I went to work for Open Source Applications Foundation and realized that the Chandler project could benefit from my experience with parsing of date/time text I decided to start from scratch and implement the code using Python and make it truly open.
After working on the initial concept and creating something that could be shown to the Chandler folks the code has now evolved to it's current state with the help the Chandler folks, most especially Darshana.
