Run GHCi from within a Reflex FRP application and interact with it using a functional reactive interface.
A functional-reactive wrapper around GHCi that uses filesystem notifications to automatically reload haskell source files.
Reflex.Process.GHCi provides the core GHCi process-running infrastructure. If you want to run your own GHCi, directly control when it reloads, or build your own custom interface, look there.
Reflex.Vty.GHCi provides a few widgets that are useful when building a console GHCi interface. Use these components to assemble your own vty GHCi runner.
This package includes a reflex-vty-based executable, shown above. Module information (errors, warnings, etc) is shown in a scrollable pane on the top half of the screen and the output of any expression you (optionally) choose to evaluate is shown in a scrollable pane on the bottom half. The panes are resizable using the mouse.
