33[Heroku buildpack][2] for [Stack][3]. Based on the excellent [heroku-buildpack-ghc][4]

5−### Usage

5+### Useage

77Create an app with this buildpack:

99 $ heroku create --buildpack https://github.com/mfine/heroku-buildpack-stack.git

1010

11−Set this buildpack on an existing app:

11+Set this buildpack on an exiting app:

1212

1313 $ heroku buildpacks:set https://github.com/mfine/heroku-buildpack-stack

1414

15−Binary executables are placed in `/app/.local/bin/` after compilation, a directory which Heroku includes in your `$PATH`, so assuming that your application is [binding to `$PORT`](https://devcenter.heroku.com/articles/dynos#web-dynos), you can serve your app by [creating a `Procfile`](https://devcenter.heroku.com/articles/procfile) at your project root that defines a `web` process type for the `executable` defined in your `.cabal` file:

16−

17− $ cat *.cabal | grep executable

18− executable YOURAPPNAME-exe

19−

20− $ echo "web: YOURAPPNAME-exe" >> Procfile

22−

23−### Templating stack.yaml

24−

25−To avoid committing secrets into `stack.yaml` for access to private

26−repos, an app's config vars values can be substituted for tags

27−enclosed in double brackets. For example, given a `stack.yaml` containing:

28−

29− packages:

30− -location:

31− git: https://mfine:{{GITPASS}}@github.com/mfine/heroku-buildpack-stack.git

32−

33−and an application with config vars:

34−

35− $ heroku config -app calm-storm-51595

36− === murmuring-beyond-51595 Config Vars

37− GITPASS: abc123

38− $

39−

40−before compilation, the `stack.yaml` will be substituted as follows:

41−

42− packages:

43− -location:

44− git: https://mfine:abc123@github.com/mfine/heroku-buildpack-stack.git

45−

47−### Makefile Support

48−

49−This buildpack now supports an optional Makefile, in case you need to coordinate

50−other build steps with Stack. It assumes that the Makefile includes a `make

51−install` target that uses the Stack build command with the flag `--copy-bins`.

52−For example, a possible `install` target configuration in the Makefile could be:

53−

54− install:

55− stack build --copy-bins
