 # 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.
+Both Neovim and Vim can be configured to include your favorite plugins
+and additional libraries.
+
 Loading can be deferred; see examples.

-Vim packages, VAM (=vim-addon-manager) and Pathogen are supported to load
-packages.
+At the moment we support three different methods for managing plugins:
+
+- Vim packages (*recommend*)
+- VAM (=vim-addon-manager)
+- Pathogen

+For Neovim the `configure` argument can be overridden to achieve the same:

+```

+  configure = {
+    customRC = ''
+      # here your custom configuration goes!
+    '';

 To store you plugins in Vim packages the following example can be used:

-};
+  };
+}
 ```

-## VAM
+For Neovim the syntax is

-### dependencies by Vim plugins
+```
+neovim.override {
+  configure = {
+    customRC = ''
+      # here your custom configuration goes!
+    '';
+    packages.myVimPackage = with pkgs.vimPlugins; {
+      # see examples below how to use custom packages
+      start = [ ];
+      opt = [ ];
+    };
+  };
+}
+```
+
+The resulting package can be added to `packageOverrides` in `~/.nixpkgs/config.nix` to make it installable:
+
+```
+{
+  packageOverrides = pkgs: with pkgs; {
+    myVim = vim_configurable.customize {
+      name = "vim-with-plugins";

+      configure = {
+      # add here code from the example section
+      };
+    };
+  };
+}
+```
+
+After that you can install your special grafted `myVim` or `myNeovim` packages.

 VAM introduced .json files supporting dependencies without versioning

+## Adding new plugins to nixpkgs
+
+In `pkgs/misc/vim-plugins/vim-plugin-names` we store the plugin names
+for all vim plugins we automatically generate plugins for.
+The format of this file `github username/github repository`:
+For example https://github.com/scrooloose/nerdtree becomes `scrooloose/nerdtree`.
+After adding your plugin to this file run the `./update.py` in the same folder.
+This will updated a file called `generated.nix` and make your plugin accessible in the
+`vimPlugins` attribute set (`vimPlugins.nerdtree` in our example).
+If additional steps to the build process of the plugin are required, add an
+override to the `pkgs/misc/vim-plugins/default.nix` in the same directory.
