Feature requests, pull requests, and other feedback are welcome and appreciated (see the contribution guide). This library is still experimental, so big changes are possible!

How to Build

With reflex-platform

Enter a nix-shell for the project:

git clone
git clone
cd reflex-vty
../reflex-platform/scripts/work-on ghc ./.

From within the nix-shell you can:

  • Run the example: cabal repl example
  • Load the library in the repl: cabal repl reflex-vty
  • Build the example executable: cabal build example
  • Build the docs: cabal haddock
  • Run ghcid for immediate compiler feedback when you save a .hs file: ghcid -c "cabal repl reflex-vty --ghc-options=-Wall"
  • etc.

With cabal

Please see the tested-with field of the cabal file for known-compatible versions of GHC.

From the reflex-vty project directory:

cabal new-configure
cabal new-build # to build the library and example
cabal new-repl # to enter a repl for the library
cabal new-repl example # to enter a repl for the example executable
