Pre-booking calendar generator

If you have a pre-booking site which has a series of lectures, where you can pre-book a slot 24 hours early for not open and 48 hours early for *not open, this generator will turn all that headache into a calendar that will tell you when to book, that you can import into your calendar app.

How to use

• Download ed_event.py to a folder.
• Go to the booking website. Put the URL in the first line of a text file, and hit enter.
• Then, go to the website, hit ctrl-a / cmd-a to grab the whole site in plain text, and paste it.
• Save this as event.txt in the same folder as ed_event.py.

The text file should look similar to:

https://ease.homepages.inf.ed.ac.uk/cgi/jcb/cosign/events.pl?event=fnlp

Foundations of Natural Language Processing

• Assuming you have Python installed, go to the command line and run:

  pip install ics python ed_event.py

• You will see an "event-prebook.ics" file. Import it into whatever calendar you're using. (If you're using your OS built-in calendar app you should be able to just double-click the file to import it.)

            if not '2022' in line:
                continue
            chunks = line.split('\t')

            l_name = chunks[0]
            l_early = '*' in line

            l_start = datetime.strptime(ds, '%d %b %Y, %H:%M')
