Convert canteen meal data from Studentenwerk Münster XML to OpenMensa Feed v2 XML format

stw2openmensa

Deprecation notice

From 2016 to August 2020, Studierendenwerk Münster provided meal data as XML files (see the discussion here) but they have since stopped. Canteen data is now only available via the "My Mensa" platform.

If want to use the canteen data in a machine readable format and are looking for an alternative, take a look at the mymensa2openmensa project (see issue #15).

About

stw2openmensa is a Python script that converts canteen meal data from Studierendenwerk Münster XML to OpenMensa Feed v2 XML format.

Installation

Configuration

config.py contains a few settings that you can change, the most important being output_dir where the output data will be written to.

Quick start

Install dependencies and run the script.

pip install -r requirements.txt
python parser.py

Using virtualenv

Prepare your virtual environment:

sudo pip install virtualenv
virtualenv venv
source venv/bin/activate
pip install -r requirements.txt
deactivate

Activate your virtual environment and run the parser:

source venv/bin/activate
python parser.py
deactivate

Cronjob example using virtualenv:

Executes monday through saturday at 07:00

0 7 * * 1-6 /home/you/mensaparser/venv/bin/python /home/you/mensaparser/parser.py

Todo

• Better checks for when a canteen is closed for the day (see issue #4)

stw2openmensa's Issues

Strip spaces from meal classification

CI throws a (caught) error for Python 3.x tests:

Processing "mensa_steinfurt.xml" Conversion of "mensa_steinfurt.xml" failed: 'vgn '
Traceback (most recent call last):
  File "parser.py", line 208, in <module>
    status = StudentenwerkToOpenmensa(config.BASE_URL, config.OUT_DIR, config.USER_AGENT, filename)
  File "parser.py", line 152, in StudentenwerkToOpenmensa
    for foodicon in foodicons:
  File "parser.py", line 70, in <lambda>
    fis = map(lambda x: config.CLASSIFICATION[x.lower()], fis)
KeyError: 'vgn '

vgn should be vgn (without spaces) to match an item in the classification list

Studierendenwerk stopped providing XML data (Aasee parser stopped working)

Hey everyone,

I recently realized the parser for the Aasee canteen in Münster stopped working.

I got in touch with the canteen and they said, they indeed stopped to provide the XML. But they provide an HTML you could use to parse the meals. They send me this link: https://muenster.my-mensa.de/essen.php?v=5326049&hyp=1&lang=de&mensa=aasee#aasee_tag_2020231

So far I didn't implement a parser for openmensa, but if none of you is working on it, I would give it a try.

Cheers.

Auto create output directory?

I think, the output directory should be automatically created if it does not exist yet since this would make the project a little bit simpler to use. Is there a reason this has not been implemented?

Otherwise, I could do it :)

Edit regex to support new additives

HIstorically there only were single letter and number additives listed in menus, but now we have a bunch of three-letter additives.

The regex additives_expr and/or def getNote() needs to be amended
