User's Guide to Vim Plugins/Addons/Bundles/Scripts in Nixpkgs
Both Neovim and Vim can be configured to include your favorite plugins and additional libraries.
Loading can be deferred; see examples.
At the moment we support three different methods for managing plugins:
- Vim packages (recommend)
- VAM (=vim-addon-manager)
- Pathogen
- vim-plug
Custom configuration
Adding custom .vimrc lines can be done using the following code:
vim_configurable.customize {
# `name` specifies the name of the executable and package
name = "vim-with-plugins";
vimrcConfig.customRC = ''
set hidden
'';
}
This configuration is used when vim is invoked with the command specified as name, in this case vim-with-plugins.
For Neovim the configure argument can be overridden to achieve the same:
neovim.override {
configure = {
customRC = ''
# here your custom configuration goes!
'';
};
}
If you want to use neovim-qt as a graphical editor, you can configure it by overriding neovim in an overlay
or passing it an overridden neovimn:
neovim-qt.override {
neovim = neovim.override {
configure = {
customRC = ''
# your custom configuration
'';
};
};
}
Managing plugins with Vim packages
To store you plugins in Vim packages (the native vim plugin manager, see :help packages) the following example can be used:
vim_configurable.customize {
vimrcConfig.packages.myVimPackage = with pkgs.vimPlugins; {
# loaded on launch
start = [ youcompleteme fugitive ];
# manually loadable by calling `:packadd $plugin-name`
# however, if a vim plugin has a dependency that is not explicitly listed in
# opt that dependency will always be added to start to avoid confusion.
opt = [ phpCompletion elm-vim ];
# To automatically load a plugin when opening a filetype, add vimrc lines like:
# autocmd FileType php :packadd phpCompletion
};
}
myVimPackage is an arbitrary name for the generated package. You can choose any name you like.
For Neovim the syntax is:
neovim.override {
configure = {
customRC = ''
# here your custom configuration goes!
'';
packages.myVimPackage = with pkgs.vimPlugins; {
# see examples below how to use custom packages
start = [ ];
# If a vim plugin has a dependency that is not explicitly listed in
# opt that dependency will always be added to start to avoid confusion.
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` specifies the name of the executable and package
name = "vim-with-plugins";
# add here code from the example section
};
myNeovim = neovim.override {
configure = {
# add here code from the example section
};
};
};
}
After that you can install your special grafted myVim or myNeovim packages.
Managing plugins with vim-plug
To use vim-plug to manage your Vim plugins the following example can be used:
vim_configurable.customize {
vimrcConfig.packages.myVimPackage = with pkgs.vimPlugins; {
# loaded on launch
plug.plugins = [ youcompleteme fugitive phpCompletion elm-vim ];
};
}
For Neovim the syntax is:
neovim.override {
configure = {
customRC = ''
# here your custom configuration goes!
'';
plug.plugins = with pkgs.vimPlugins; [
vim-go
];
};
}
Managing plugins with VAM
Handling dependencies of Vim plugins
VAM introduced .json files supporting dependencies without versioning assuming that "using latest version" is ok most of the time.
Example
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'' ]; }
]
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.
