User's Guide to Vim Plugins/Addons/Bundles/Scripts in Nixpkgs

You'll get a vim(-your-suffix) in PATH also loading the plugins you want. Loading can be deferred; see examples.

VAM (=vim-addon-manager) and Pathogen plugin managers are supported. Vundle, NeoBundle could be your turn.

dependencies by Vim plugins

VAM introduced .json files supporting dependencies without versioning assuming that "using latest version" is ok most of the time.

HOWTO

First create a vim-scripts file having one plugin name per line. Example:

"tlib"
{'name': 'vim-addon-sql'}
{'filetype_regex': '\%(vim)$', 'names': ['reload', 'vim-dev-plugin']}

Such vim-scripts file can be read by VAM as well like this:

call vam#Scripts(expand('~/.vim-scripts'), {})

Create a default.nix file:

{ nixpkgs ? import <nixpkgs> {}, compiler ? "ghc7102" }:
nixpkgs.vim_configurable.customize { name = "vim"; vimrcConfig.vam.pluginDictionaries = [ "vim-addon-vim2nix" ]; }

Create a generate.vim file:

ActivateAddons vim-addon-vim2nix
let vim_scripts = "vim-scripts"
call nix#ExportPluginsForNix({
\  'path_to_nixpkgs': eval('{"'.substitute(substitute(substitute($NIX_PATH, ':', ',', 'g'), '=',':', 'g'), '\([:,]\)', '"\1"',"g").'"}')["nixpkgs"],
\  'cache_file': '/tmp/vim2nix-cache',
\  'try_catch': 0,
\  'plugin_dictionaries': ["vim-addon-manager"]+map(readfile(vim_scripts), 'eval(v:val)')
\ })

Then run

nix-shell -p vimUtils.vim_with_vim2nix --command "vim -c 'source generate.vim'"

You should get a Vim buffer with the nix derivations (output1) and vam.pluginDictionaries (output2). You can add your vim to your system's configuration file like this and start it by "vim-my":

my-vim =
 let plugins = let inherit (vimUtils) buildVimPluginFrom2Nix; in {
      copy paste output1 here
 }; in vim_configurable.customize {
   name = "vim-my";

   vimrcConfig.vam.knownPlugins = plugins; # optional
   vimrcConfig.vam.pluginDictionaries = [
      copy paste output2 here
   ];

   # Pathogen would be
   # vimrcConfig.pathogen.knownPlugins = plugins; # plugins
   # vimrcConfig.pathogen.pluginNames = ["tlib"];
 };

Sample output1:

"reload" = buildVimPluginFrom2Nix { # created by nix#NixDerivation
  name = "reload";
  src = fetchgit {
    url = "git://github.com/xolox/vim-reload";
    rev = "0a601a668727f5b675cb1ddc19f6861f3f7ab9e1";
    sha256 = "0vb832l9yxj919f5hfg6qj6bn9ni57gnjd3bj7zpq7d4iv2s4wdh";
  };
  dependencies = ["nim-misc"];

};
[...]

Sample output2:

[
  ''vim-addon-manager''
  ''tlib''
  { "name" = ''vim-addon-sql''; }
  { "filetype_regex" = ''\%(vim)$$''; "names" = [ ''reload'' ''vim-dev-plugin'' ]; }
]

Important repositories

• vim-pi is a plugin repository from VAM plugin manager meant to be used by others as well used by

• vim2nix which generates the .nix code
