Flags

Manual Flags

Name	Description	Default
use-reflex-optimizer	Use the GHC plugin Reflex.Optimizer on some of the modules in the package. This is still experimental.	Disabled
use-template-haskell	Use template haskell to generate lenses	Enabled
debug-trace-events	Add instrumentation that outputs the stack trace of the definition of an event whenever it is subscribed to. Warning: It is very slow!	Disabled
fast-weak	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	Disabled
debug-propagation	Enable debugging of spider internals	Disabled
debug-cycles	Enable debugging of event cycles	Disabled

Automatic Flags

Name	Description	Default
split-these	Use split these/semialign packages	Enabled

Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info

Reflex

Practical Functional Reactive Programming

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

Reflex-DOM is a framework built on Reflex that facilitates the development of web pages, including highly-interactive single-page apps.

A summary of Reflex functions is available in the quick reference.

Visit https://reflex-frp.org/ for more information, tutorials, documentation and examples.

Hacking

Use the ./scripts/hack-on reflex script in Reflex Platform to checkout the source code of reflex locally in reflex-platform/reflex directory. Then do modifications to the source in place, and use the ./try-reflex or ./scripts/work-on scripts to create the shell to test your changes.
