    • Package Flags

      use-reflex-optimizer
       (off by default)

      Use the GHC plugin Reflex.Optimizer on some of the modules in the package. This is still experimental.

      use-template-haskell
       (on by default)

      Use template haskell to generate lenses

      debug-trace-events
       (off by default)

      Add instrumentation that outputs the stack trace of the definition of an event whenever it is subscribed to. Warning: It is very slow!

      fast-weak
       (off by default)

      Use the primitive implementation of FastWeak in GHCJS; note that this requires GHCJS to be built with FastWeak and FastWeakBag present in the RTS, which is not the default

      debug-propagation
       (off by default)

      Enable debugging of spider internals

      debug-cycles
       (off by default)

      Enable debugging of event cycles

      split-these
       (on by default)

      Use split these/semialign packages

Reflex

Haskell Hackage BSD3 License

Interactive programs without callbacks or side-effects. Functional Reactive Programming (FRP) uses composable events and time-varying values to describe interactive systems as pure functions. Just like other pure functional code, functional reactive code is easier to get right on the first try, maintain, and reuse.

Reflex is a fully-deterministic, higher-order Functional Reactive Programming interface and an engine that efficiently implements that interface.

Hacking

From the root of a Reflex Platform checkout, run ./scripts/hack-on haskell-overlays/reflex-packages/dep/reflex. This will check out the reflex source code into the haskell-overlays/reflex-packages/dep/reflex directory. You can then point that checkout at your fork, make changes, etc. Use the ./try-reflex or ./scripts/work-on scripts to start a shell in which you can test your changes.
