eat-api

Simple static API for the canteens of the Studierendenwerk München Oberbayern as well as some other canteens. By now, the following canteens are supported:

Usage

API

The actual API is provided by static JSON files, which can be found in the gh-pages branch of this repository. These files are created through automatic travis builds. The documentation can be found at: https://tum-dev.github.io/eat-api/docs

Basically, you need to structure a link as follows in order to access the API:

https://tum-dev.github.io/eat-api/<canteen>/<year>/<week-number>.json

Example

The following link would give you the menu of Mensa Garching for week 20 in 2019:

https://tum-dev.github.io/eat-api/mensa-garching/2019/20.json

CLI

The JSON files are produced by the tool shown in this repository. Hence, it is either possible to access the API or use the tool itself to obtain the desired menu data. The CLI needs to be used as follows:

$ src/python3 main.py --help
usage: main.py [-h] [-p CANTEEN] [-d DATE] [-j PATH] [-c] [--openmensa PATH]
               [--canteens] [--language LANGUAGE]

options:
  -h, --help            show this help message and exit
  -p CANTEEN, --parse CANTEEN
                        the canteen you want to eat at
  -d DATE, --date DATE  date (DD.MM.YYYY) of the day of which you want to get
                        the menu
  -c, --combine         creates a "combined.json" file containing all dishes
                        for the canteen specified
  --openmensa PATH      directory for OpenMensa XML output (date parameter
                        will be ignored if this argument is used)
  --canteens            prints all available canteens formated as JSON
  --language LANGUAGE   The language to translate the dish titles to, needs an
                        DeepL API-Key in the environment variable
                        DEEPL_API_KEY_EAT_API

It is mandatory to specify the canteen (e.g. mensa-garching). Furthermore, you can specify a date, for which you would like to get the menu. If no date is provided, all the dishes for the current week will be printed to the command line. the --jsonify option is used for the API and produces some JSON files containing the menu data.

Example

Here are some sample calls:

# Get the menus for the whole current week at mensa-garching
$ python src/main.py -p mensa-garching

# Get the menu for April 2 at mensa-arcisstrasse
$ python src/main.py -p mensa-arcisstrasse -d 02.04.2019

Translations

Dish titles are provided only in german by the Studentenwerk. We offer the possibility to translate them using the DeepL API. In order to use the API, there needs to be an API key provided in the environment variable DEEPL_API_KEY_EAT_API. The target language can be specified using the --language option using one of the languages supported by DeepL e.g. EN-US.

Generating canteens.json and label.json

The canteens.json and label.json are generated from the Canteen and Label enum. To generate them, run enum_json_creator.py [<path/to/directory>]. This will also generate a languages.json file, which contains the languages supported by the Label enum. If no path is specified, the Python script stores them in ./dist/enums.

Contributing

Getting started

1. Fork and clone this repository
2. Install the python dependencies (Python 3.9+ required):

• sudo apt install libxml2 libxml2-dev libxslt1-dev
• pip3 install poetry
• poetry install

pre-commit

Code quality is ensured via various tools bundled in pre-commit.

You can install pre-commit, so it will automatically run on every commit:

pre-commit install

This will check all files modified by your commit and will prevent the commit if a hook fails. To check all files, you can run

pre-commit run --all-files

This will also be run by CI if you push to the repository.

Run tests:

• All the tests: PYTHONPATH=src/ pytest
• A specific test class: PYTHONPATH=src/ pytest src/test/test_menu_parser.py::MenuParserTest
