No buses

It doesn't show any buses on my Ubuntu 22.04 workstation:

$ pip install next-bus-bot

Hello Dimitri, Thanks for using NBB !

Indeed after filtering there are no buses (by default only the future buses leaving Mare du Vivier towards Gare du Guichet are displayed). This is due to the API returning partial results. Either the API called is (1) not up to date/ incomplete or (2) there is some caching on the IDFM side. I actually don't know how to discriminate between those two possibilities.

An another solution would be to called an another API, that I found by reverse engineering the QR code at the bus stop. An example: https://api-iv.iledefrance-mobilites.fr/lines/v2/line:IDFM:C01561/stops/stop_area:IDFM:420704/realTime

The only problem of this API is that it only gives the buses for a single line. So to get all the buses incoming, it would requires to have the list of all the lines passing at each stop (This data is available of course as a whole (roughly 60MB in CSV), but I would rather choose to request this (there is an APi for that also) only for stop of interests (e.g. the one defined in the config file). I guess this week-end project will need another one ...
