Example Nix + Purescript project

This is a simple example project for setting up Purescript development environment using Nix. The basic tooling like Pulp, Purescript compiler and psc-package are downloaded from a pinned revision of nixpkgs. This allows us to use new Purescript compiler and things like that from the pinned revision while otherwise sticking with stable NixOS release.

In this example, the Purescript libraries are installed using psc-package and Nix is only used to install the basic tooling.

Usage

Shell environment

1. git clone git://github.com/kaitanie/nix-purescript-example-project
2. cd nix-purescript-example-project
3. nix-shell

Purescript, psc-package, and such from the pinned nixpkgs version should now be available in the `nix-shell` environment and can be used normally.

Known issues

Currently the version of Pulp from nixpkgs throws exception when used

The relevant issue is here: NixOS/nixpkgs#40406

Currently the workaround is to use `npm install -g pulp` and use that one instead of the nixpkgs version.
