Point of this project was to write a chat bot in pure haskell without any platform-specific wrapper libraries. After receiving a message this bot retrieves data from extrernal API specified in the config and responds with a formated message.
This bot is written in more or less generic fashion and is able to work with multiple messaging platforms and Data APIs based on a config file.
Vk and telegram were the only sane options, because all other platforms have really comlpex APIs, that are intended to be used with a wrapper library (and with a wrapper, project would have been to easy).
Bot reads a JSON file a startup.
- A hardcoded client (
API/Weather.hs) that comunicates with OpenWeatherAPI. - Generic API client (
API/GenericAPI.hs), that works with whatever that is defined inside the config file.
Since this client isn't meant to work with any particular API, I can't write a formater for API's response, because I have no idea, what I will actually receive. That's why GenericAPI converts JSON it received from a service to yaml, which is argaubly more readable, and then sends it as a response to a user.
