Gaël Deest 910a3ae7ec Upgrade GHCJS to 8.6
This allows us to deprecate GHCJS 8.4 (which makes sense, as vanilla GHC
< 8.6 is already deprecated).

We re-use GHCJS from reflex-platform, which unfortunately isn't
up-to-date with latest GHC and is only 8.6. The benefit of using
reflex-platform is that it provides nix expressions for GHCJS + a binary
nix cache.

reflex-platform patches text to use a JS-String based internal
representation for performance reasons, so we provide a few haskell
dependencies from reflex-platform as well:

- hashable
- attoparsec

As those rely on text's internal representation but have been patched
for reflex-platform.

README.md

You can use the shell.nix from this directory to build the servant packages or even the tutorial or cookbook if you want to, optionally.

Just the servant packages:

$ nix-shell nix/shell.nix

Everything needed for the tutorial and the cookbook too:

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

The shell.nix file also supports specifying a particular ghc version, e.g:

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

Possible GHC versions

  • ghc865Binary
  • ghc884
  • ghc8104 - default
  • ghc901

Cabal users

GHC version can be chosen via the nix-shell parameter

cabal build all

Stack version

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

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