1You can use the `shell.nix` from this directory

2to build the servant packages or even the tutorial

3or cookbook if you want to, optionally.

5Just the servant packages:

7``` sh

8$ nix-shell nix/shell.nix

9```

11Everything needed for the tutorial and the

12cookbook too:

14``` sh

15$ nix-shell nix/shell.nix --arg tutorial true

16```

18The `shell.nix` file also supports specifying

19a particular ghc version, e.g:

21``` sh

22$ nix-shell nix/shell.nix --argstr compiler ghcHEAD

23```

25**Possible GHC versions**

26- `ghc865Binary`

27- `ghc884`

28- `ghc8104` - default

29- `ghc901`

31### Cabal users

33GHC version can be chosen via the nix-shell parameter

35`cabal build all`

37### Stack version

39Since the ghc version is set by the LTS version, it is preferable to use the `ghc8104` version parameter for the nix-shell.

41`stack --no-nix --system-ghc <command>`
