Sometimes it's needed to override parts of `vim_configurable`, for instance when using ENSIME (http://ensime.github.io/), in this case you need a Python interpreter and the modules `sexpdata` and `websocket_client`. However overriding `vim_configurable` is quite hard as we run `vimUtils.makeCustomizable` over the default comming from `configurable.nix`. Therefore it's necessary to copy the code from `all-packages.nix` and alter the parts you need: https://nixos.org/nix-dev/2017-April/023364.html In order to simplify overriding `vim_configurable` I added an `override` and an `overrideAttrs` function to `vimutils.makeCustomizable` to ensure that the customization capabilities won't be lost after altering the derivation. Now it's possible to write expressions like this without evaluation failures: ``` with pkgs; let vimPy3 = vim_configurable.override { python = python3; }; in vimPy3.customize { ... } ```
Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-17.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-17.09
For pull-requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
