vega-cli and vega-lite packaged for nix (with node2nix)

README.md

This is packaging the vega command line tools for nix (https://vega.github.io/vega/usage/#cli). Vega is a handy declarative visualization tool and this cli allows to convert vega specifications directly to svg/pdf/png instead of looking at them online.

Basically what I did was to run:

nix-shell -p nodePackages.node2nix --command "node2nix -i <(echo '[\"vega-cli\", \"vega-lite\"]')"

Then I added a few extra dependencies to the generated default.nix such that the last lines look like this:

...
import ./node-packages.nix {
  inherit (pkgs) fetchurl fetchgit;
  inherit nodeEnv;
  globalBuildInputs = with pkgs; [ nodePackages.node-pre-gyp pkgconfig pixman cairo pango libjpeg ];
}

you can then either build it with nix-build or you can import it in a shell.nix, for example to use it together with hvega:

{ pkgs ? import <nixpkgs> { } }:

with pkgs;
let
  vega = (import ./vega-cli { inherit pkgs; });
  haskenv = haskellPackages.ghcWithPackages (p: [
    p.req
    p.gnuplot
    p.aeson
    p.cassava
    p.Frames
    p.microlens-platform
    p.foldl
    p.hvega
  ]);
in mkShell {
  buildInputs = [
    gnuplot
    haskenv
    haskellPackages.haskell-language-server
    vega.vega-cli
    vega.vega-lite
  ];
}
