Heroku Buildpack for Haskell modified to install GHC and Haste

in the running environment so that your web application can invoke GHC and Haste to build and run programs at exploitation time.

It is used to install heroku instances of the tryhplay project

This is a Heroku buildpack for Haskell apps. It uses GHC 7.4.1 and cabal-1.16.0.1.

Usage

Use a linux box. Don´t do this under windows. it does not work.

Your project need at least these files:

$ ls
Procfile app.cabal src

Create your heroku instance: (previously sign in and download the heroku soft: http://heroku.com)

$ heroku apps:create instance-name 

install anvil to allow large compilations:

$ heroku plugins:install https://github.com/ddollar/heroku-anvil

Build and release your project:

$ heroku build -r -b https://github.com/agocorona/heroku-buildpack-haste.git

Set the PATH environment. Run this in the console:

$ heroku config:set PATH=/app/ghc/bin:/app/.cabal/bin:/app/bin:/app/node_modules/.bin:node_modules/.bin:/app/bin:/app/node_modules/.bin:/usr/local/bin:/usr/bin:/bin 

Then you can invoke ghc, cabal, hastec, haste-inst etc from your web application.
