Install PFHub using Nix

A nix expression to host this website. Follow these Nix notes for installing Nix.

Usage

After installing Nix and cloning this repository, run

$ nix-shell

in the base directory. At that point, you should be able to run all the functionality as outlined in the PFHub travis.yml file including

$ jekyll serve

to view the website locally.

Usage for OS X

If using OS X run

$ nix-shell shell-osx.nix

instead. This install does not install Jupyter or Bokeh which are not essential for running the website. Both of these packages have proved problematic when installing with Nix on OS X.

Update Packages

The dependencies are all fixed in the above installation. To update the Python, Ruby and Javascript dependencies use the following. First change directory to the _nix directory.

Ruby

Using Bundix.

Update the Gemfile if necessary and then

$ nix-shell -p bundler
[nix-shell]$ bundler package --no-install --path vendor
[nix-shell]$ rm -rf .bundler vendor
[nix-shell]$ exit
$ $(nix-build '<nixpkgs>' -A bundix)/bin/bundix
$ rm result

This updates the installed gems.

Python

Instlal pypi2nix and then,

$ pypi2nix -V "3.6" -r requirements.txt

Javascript

Install node2nix.

$ nix-env -f '<nixpkgs>' -iA nodePackages.node2nix

Then run

$ node2nix --input node-packages.json --output node-packages.nix --composition node.nix

Edit node.nix and replace nodejs-4_x with nodejs in the 5th line.
