Readme for reflex-ghci-0.1.5.2
[back to package description]reflex-ghci
Run GHCi from within a Reflex FRP application and interact with it using a functional reactive interface.
Library
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.
Executable
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.
$ reflex-ghci -h
Welcome to reflex-ghci 0.1.4.0
Usage: reflex-ghci [-c|--command COMMAND] [-e|--expression EXPR]
Run a Haskell REPL that automatically reloads when source files change.
Available options:
-c,--command COMMAND The ghci/cabal repl command to
run (default: "cabal repl --repl-options=-Wall")
-e,--expression EXPR The optional expression to evaluate once modules have
successfully loaded
-h,--help Show this help text
