# Vim {#vim}
|
||
|
||
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 {#custom-configuration}
|
||
|
||
Adding custom .vimrc lines can be done using the following code:
|
||
|
||
```nix
|
||
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:
|
||
|
||
```nix
|
||
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:
|
||
|
||
```nix
|
||
neovim-qt.override {
|
||
neovim = neovim.override {
|
||
configure = {
|
||
customRC = ''
|
||
# your custom configuration
|
||
'';
|
||
};
|
||
};
|
||
}
|
||
```
|
||
|
||
## Managing plugins with Vim packages {#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:
|
||
|
||
```nix
|
||
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:
|
||
|
||
```nix
|
||
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:
|
||
|
||
```nix
|
||
{
|
||
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.
|
||
|
||
### What if your favourite Vim plugin isn’t already packaged? {#what-if-your-favourite-vim-plugin-isnt-already-packaged}
|
||
|
||
If one of your favourite plugins isn't packaged, you can package it yourself:
|
||
|
||
```nix
|
||
{ config, pkgs, ... }:
|
||
|
||
let
|
||
easygrep = pkgs.vimUtils.buildVimPlugin {
|
||
name = "vim-easygrep";
|
||
src = pkgs.fetchFromGitHub {
|
||
owner = "dkprice";
|
||
repo = "vim-easygrep";
|
||
rev = "d0c36a77cc63c22648e792796b1815b44164653a";
|
||
sha256 = "0y2p5mz0d5fhg6n68lhfhl8p4mlwkb82q337c22djs4w5zyzggbc";
|
||
};
|
||
};
|
||
in
|
||
{
|
||
environment.systemPackages = [
|
||
(
|
||
pkgs.neovim.override {
|
||
configure = {
|
||
packages.myPlugins = with pkgs.vimPlugins; {
|
||
start = [
|
||
vim-go # already packaged plugin
|
||
easygrep # custom package
|
||
];
|
||
opt = [];
|
||
};
|
||
# ...
|
||
};
|
||
}
|
||
)
|
||
];
|
||
}
|
||
```
|
||
|
||
### Specificities for some plugins
|
||
#### Tree sitter
|
||
|
||
By default `nvim-treesitter` encourages you to download, compile and install
|
||
the required tree-sitter grammars at run time with `:TSInstall`. This works
|
||
poorly on NixOS. Instead, to install the `nvim-treesitter` plugins with a set
|
||
of precompiled grammars, you can use `nvim-treesitter.withPlugins` function:
|
||
|
||
```nix
|
||
(pkgs.neovim.override {
|
||
configure = {
|
||
packages.myPlugins = with pkgs.vimPlugins; {
|
||
start = [
|
||
(nvim-treesitter.withPlugins (
|
||
plugins: with plugins; [
|
||
tree-sitter-nix
|
||
tree-sitter-python
|
||
]
|
||
))
|
||
];
|
||
};
|
||
};
|
||
})
|
||
```
|
||
|
||
To enable all grammars packaged in nixpkgs, use `(pkgs.vimPlugins.nvim-treesitter.withPlugins (plugins: pkgs.tree-sitter.allGrammars))`.
|
||
|
||
## Managing plugins with vim-plug {#managing-plugins-with-vim-plug}
|
||
|
||
To use [vim-plug](https://github.com/junegunn/vim-plug) to manage your Vim
|
||
plugins the following example can be used:
|
||
|
||
```nix
|
||
vim_configurable.customize {
|
||
vimrcConfig.packages.myVimPackage = with pkgs.vimPlugins; {
|
||
# loaded on launch
|
||
plug.plugins = [ youcompleteme fugitive phpCompletion elm-vim ];
|
||
};
|
||
}
|
||
```
|
||
|
||
For Neovim the syntax is:
|
||
|
||
```nix
|
||
neovim.override {
|
||
configure = {
|
||
customRC = ''
|
||
# here your custom configuration goes!
|
||
'';
|
||
plug.plugins = with pkgs.vimPlugins; [
|
||
vim-go
|
||
];
|
||
};
|
||
}
|
||
```
|
||
|
||
## Managing plugins with VAM {#managing-plugins-with-vam}
|
||
|
||
### Handling dependencies of Vim plugins {#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 {#example}
|
||
|
||
First create a vim-scripts file having one plugin name per line. Example:
|
||
|
||
```vim
|
||
"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:
|
||
|
||
```vim
|
||
call vam#Scripts(expand('~/.vim-scripts'), {})
|
||
```
|
||
|
||
Create a default.nix file:
|
||
|
||
```nix
|
||
{ nixpkgs ? import <nixpkgs> {}, compiler ? "ghc7102" }:
|
||
nixpkgs.vim_configurable.customize { name = "vim"; vimrcConfig.vam.pluginDictionaries = [ "vim-addon-vim2nix" ]; }
|
||
```
|
||
|
||
Create a generate.vim file:
|
||
|
||
```vim
|
||
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
|
||
|
||
```bash
|
||
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":
|
||
|
||
```nix
|
||
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:
|
||
|
||
```nix
|
||
"reload" = buildVimPluginFrom2Nix { # created by nix#NixDerivation
|
||
name = "reload";
|
||
src = fetchgit {
|
||
url = "https://github.com/xolox/vim-reload";
|
||
rev = "0a601a668727f5b675cb1ddc19f6861f3f7ab9e1";
|
||
sha256 = "0vb832l9yxj919f5hfg6qj6bn9ni57gnjd3bj7zpq7d4iv2s4wdh";
|
||
};
|
||
dependencies = ["nim-misc"];
|
||
|
||
};
|
||
[...]
|
||
```
|
||
|
||
Sample output2:
|
||
|
||
```nix
|
||
[
|
||
''vim-addon-manager''
|
||
''tlib''
|
||
{ "name" = ''vim-addon-sql''; }
|
||
{ "filetype_regex" = ''\%(vim)$$''; "names" = [ ''reload'' ''vim-dev-plugin'' ]; }
|
||
]
|
||
```
|
||
|
||
## Adding new plugins to nixpkgs {#adding-new-plugins-to-nixpkgs}
|
||
|
||
Nix expressions for Vim plugins are stored in [pkgs/applications/editors/vim/plugins](https://github.com/NixOS/nixpkgs/tree/master/pkgs/applications/editors/vim/plugins). For the vast majority of plugins, Nix expressions are automatically generated by running [`./update.py`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/editors/vim/plugins/update.py). This creates a [generated.nix](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/editors/vim/plugins/generated.nix) file based on the plugins listed in [vim-plugin-names](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/editors/vim/plugins/vim-plugin-names). Plugins are listed in alphabetical order in `vim-plugin-names` using the format `[github username]/[repository]@[gitref]`. 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](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/editors/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:
|
||
|
||
```nix
|
||
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, run `./update.py --add "[owner]/[name]"`. **NOTE**: This script automatically commits to your git repository. Be sure to check out a fresh branch before running.
|
||
|
||
Finally, there are some plugins that are also packaged in nodePackages because they have Javascript-related build steps, such as running webpack. Those plugins are not listed in `vim-plugin-names` or managed by `update.py` at all, and are included separately in `overrides.nix`. Currently, all these plugins are related to the `coc.nvim` ecosystem of Language Server Protocol integration with vim/neovim.
|
||
|
||
## Updating plugins in nixpkgs {#updating-plugins-in-nixpkgs}
|
||
|
||
Run the update script with a GitHub API token that has at least `public_repo` access. Running the script without the token is likely to result in rate-limiting (429 errors). For steps on creating an API token, please refer to [GitHub's token documentation](https://docs.github.com/en/free-pro-team@latest/github/authenticating-to-github/creating-a-personal-access-token).
|
||
|
||
```sh
|
||
GITHUB_API_TOKEN=my_token ./pkgs/applications/editors/vim/plugins/update.py
|
||
```
|
||
|
||
Alternatively, set the number of processes to a lower count to avoid rate-limiting.
|
||
|
||
```sh
|
||
./pkgs/applications/editors/vim/plugins/update.py --proc 1
|
||
```
|
||

||
## Important repositories {#important-repositories}
|
||
|
||
- [vim-pi](https://bitbucket.org/vimcommunity/vim-pi) is a plugin repository
|

from VAM plugin manager meant to be used by others as well used by
|
||
|
||
- [vim2nix](https://github.com/MarcWeber/vim-addon-vim2nix) which generates the
