# Tracktrain

*experimental, don't expect things to work for now*

A thing to track trains via GPS (eventually), generating real-time data for use
in e.g. passenger information systems. Timetables are read in via GTFS.

## Server
I run a test-deployment of this at (tracktrain.stuebinm.eu)[https://tracktrain.stuebinm.eu].

It self-generates an OpenAPI description of the currently implemented routes at
(`/api`)[https://tracktrain.stuebinm.eu/debug/openapi].



## Packages & Modules

This project is split into a few haskell packages:
 - the tracktrain executable in `app/`, handling startup & config
 - the tracktrain library implementing the business logic in `lib/`
 - the gtfs realtime library (generated with `hprotoc` from the gtfs realtime 
   proto file, along with a very little glue code in `Servant.GTFS.Realtime`)
   in `gtfs/`
 - that's it for now, but there'll probably be more
