I've added a few features: - Search in 15.09 as well as 16.03 - Search in parameters - A few more packages with parameters are recognized, e. g. firefox now shows parameters - Better error handling: If a parameter fails while trying to determine what kind it is, it's simply not displayed, but anything else is
As before, demo can be foud here: http://schmitthenner.eu/nixos-homepage/nixos/packages.html. (compare to official version: https://nixos.org/nixos/packages.html). You might need to clear your cache to see the new version. I've also added a pull request: https://github.com/NixOS/nixos-homepage/pull/78. Feel free to comment either on the list or on github. Have a great day!
