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

```
"tlib"

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

Create a default.nix file:

nixpkgs.vim_configurable.customize { name = "vim"; vimrcConfig.vam.pluginDictionaries = [ "vim-addon-vim2nix" ]; }

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"],

## 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.
Nix expressions for Vim plugins are stored in [pkgs/misc/vim-plugins](/pkgs/misc/vim-plugins). For the vast majority of plugins, Nix expressions are automatically generated by running [`./update.py`](/pkgs/misc/vim-plugins/update.py). This creates a [generated.nix](/pkgs/misc/vim-plugins/generated.nix) file based on the plugins listed in [vim-plugin-names](/pkgs/misc/vim-plugins/vim-plugin-names). Plugins are listed in alphabetical order in `vim-plugin-names` using the format `[github username]/[repository]`. For example https://github.com/scrooloose/nerdtree becomes `scrooloose/nerdtree`.
Some plugins require overrides in order to function properly. Overrides are placed in [overrides.nix](/pkgs/misc/vim-plugins/overrides.nix). Overrides are most often required when a plugin requires some dependencies, or extra steps are required during the build process. For example `deoplete-fish` requires both `deoplete-nvim` and `vim-fish`, and so the following override was added:
```
deoplete-fish = super.deoplete-fish.overrideAttrs(old: {
dependencies = with super; [ deoplete-nvim vim-fish ];
});
```
Sometimes plugins require an override that must be changed when the plugin is updated. This can cause issues when Vim plugins are auto-updated but the associated override isn't updated. For these plugins, the override should be written so that it specifies all information required to install the plugin, and running `./update.py` doesn't change the derivation for the plugin. Manually updating the override is required to update these types of plugins. An example of such a plugin is `LanguageClient-neovim`.
To add a new plugin:
1. run `./update.py` and create a commit named "vimPlugins: Update",
2. add the new plugin to [vim-plugin-names](/pkgs/misc/vim-plugins/vim-plugin-names) and add overrides if required to [overrides.nix](/pkgs/misc/vim-plugins/overrides.nix),
3. run `./update.py` again and create a commit named "vimPlugins.[name]: init at [version]" (where `name` and `version` can be found in [generated.nix](/pkgs/misc/vim-plugins/generated.nix)), and
4. create a pull request.
