A Bridge Far Away... is a game engine written in haskell, using vulkan and glfw. the code structure is devided up into many parts arbitrarily named. paracletus is the graphics engine, anamnesis is the program structure and continuation monad, and epiklesis is the lua interpreter. Works on windows, linux, or mac, probably anything with GHC and vulkan.
the mod directory contains examples of lua files for how to define windows, UI elements, and general game structures. all these commands could also be run in game from the shell. mod/base/config.lua contains the settings for key layout and such.
use cabal new-build abfa to download dependencies and compile
use ./dist-newstyle/build/[arch]/ghc-[ver]/abfa-[ver]/x/abfa/opt/build/abfa/abfa +RTS -s -M[x]m -N[n] to run with x megabytes and n cores
performance is increased drastically by disabling the development flag, but compilation takes forever
to create profiling files, use cabal new-build --enable-library-profiling --enable-profiling abfa to build, and -prof -fprof-auto in the ghc-options of the cabal file. run with flags +RTS -s -p -hy -M[x]m -N[n]
