For various reasons some work has not been committed to the main trunk repositories. You find a description about some of them here:

Contents

edit Haskell overlay (stable)

Let's you install nearly all hackage packages easily. Older and newer gtk2hs supported. hack-nix also provides a convenient way to setup multiple build environments for a project nixpkgs-haskell-overlay

edit Ruby overlay (stable)

purpose: abstract away tedious task of finding matching versions and packaging ruby packages. (source: RubyGems) Let's you install all packages known by gem. (Contact Marc Weber if you want to try it, you need some more patches). nixpkgs-ruby-overlay Usage example (~/.nixpkgs/config.nix) 

   rubyEnv = 
     let ro = (pkgs.overlay "ruby");
     in ro.rubyEnv19 {
         p = {
            activesupport =  "=" "2.3.9" ;
         };
         # note: the gem dependencies of activesupport will be found automatically
         names = [ "activesupport" ];
     };

Note: if two packages resolve different versions of the same dependency Nix fails. You can work around it by forcing a version as shown above.

edit Python overlay (experimental)

purpose: abstract away tedious task of finding matching versions and packaging python packages (source: PyPi package index) Let's you install all packages known by gem. (Contact Marc Weber if you want to try it, you need some more patches). Open issues: How to find out which package has to be run with python-2.x or python-3 and such. nixpkgs-python-overlay

edit nixpkgs-utilities

a very small collection of scripts you can run to verify that you don't break too much when comitting. This is work in progress nixpkgs-dev-utilities. Current goals:

  • verify that everything still evaluates
  • verify that most important things build on your system
  • preview of what will be rebuild if you change something


edit ocamlPackages

A small collections of OCaml-related packages: download.

Reasons for not committing it to trunk: Proof of concept, still experimenting, trying to find a good way to cope with findlib and other OCaml-specific practices.
