From 6c25964c0165530e7db6650eea79cbac99031353 Mon Sep 17 00:00:00 2001 From: stuebinm Date: Sat, 2 Jul 2022 00:16:02 +0200 Subject: gtfs realtime proof of concept this adds a package for protobuf stuff, generated via hprotoc. Seems to work kinda fine? (the generated API is horrible though, will have to write some wrappers for that) --- gtfs/GTFS/Realtime/TripDescriptor.hs | 128 +++++++++++++++++++++++++++++++++++ 1 file changed, 128 insertions(+)
