# Adding Plugins {#sec-additional-plugins}
|
|
|
|
To add a new neovim plugin, first add the source url in the inputs section of `flake.nix`
|
|
|
|
```nix
|
|
|
|
{
|
|
inputs = {
|
|
# ...
|
|
neodev-nvim = {
|
|
url = "github:folke/neodev.nvim";
|
|
flake = false;
|
|
};
|
|
# ...
|
|
};
|
|
}
|
|
```
|
|
|
|
Then add the name of the plugin into the `availablePlugins` variable in `lib/types/plugins.nix`:
|
|
|
|
```nix
|
|
# ...
|
|
availablePlugins = [
|
|
# ...
|
|
"neodev-nvim"
|
|
];
|
|
```
|
|
|
|
You can now reference this plugin using its string name:
|
|
|
|
```nix
|
|
config.vim.startPlugins = ["neodev-nvim"];
|
|
```
|
|
|
|
## Modular setup options {#sec-modular-setup-options}
|
|
|
|
Most plugins is initialized with a call to `require('plugin').setup({...})`.
|
|
|
|
We use a special function that lets you easily add support for such setup options in a modular way:
|
|
`mkPluginSetupOption`.
|
|
|
|
Once you have added the source of the plugin as shown above, you can define the setup options like
|
|
this:
|
|
|
|
```nix
|
|
# in modules/.../your-plugin/your-plugin.nix
|
|
|
|
{lib, ...}:
|
|
let
|
|
inherit (lib.types) bool int;
|
|
inherit (lib.nvim.types) mkPluginSetupOption;
|
|
in {
|
|
options.vim.your-plugin = {
|
|
setupOpts = mkPluginSetupOption "plugin name" {
|
|
enable_feature_a = mkOption {
|
|
type = bool;
|
|
default = false;
|
|
# ...
|
|
};
|
|
|
|
number_option = mkOption {
|
|
type = int;
|
|
default = 3;
|
|
# ...
|
|
};
|
|
};
|
|
};
|
|
}
|
|
```
|
|
|
|
```nix
|
|
# in modules/.../your-plugin/config.nix
|
|
{lib, config, ...}:
|
|
let
|
|
cfg = config.vim.your-plugin;
|
|
in {
|
|
vim.luaConfigRC = lib.nvim.dag.entryAnywhere ''
|
|
require('plugin-name').setup(${lib.nvim.lua.toLuaObject cfg.setupOpts})
|
|
'';
|
|
}
|
|
```
|
|
|
|
This above config will result in this lua script:
|
|
|
|
```lua
|
|
require('plugin-name').setup({
|
|
enable_feature_a = false,
|
|
number_option = 3,
|
|
})
|
|
```
|
|
|
|
Now users can set any of the pre-defined option field, and can also add their own fields!
|
|
|
|
```nix
|
|
# in user's config
|
|
{
|
|
vim.your-plugin.setupOpts = {
|
|
enable_feature_a = true;
|
|
number_option = 4;
|
|
another_field = "hello";
|
|
size = { # nested fields work as well
|
|
top = 10;
|
|
};
|
|
};
|
|
}
|
|
```
|
|
|
|
## Details of toLuaObject {#sec-details-of-toluaobject}
|
|
|
|
As you've seen above, `toLuaObject` is used to convert our nix attrSet `cfg.setupOpts`, into a lua
|
|
table. Here are some rules of the conversion:
|
|
|
|
1. nix `null` converts to lua `nil`
|
|
2. number and strings convert to their lua counterparts
|
|
3. nix attrSet/list converts into lua tables
|
|
4. you can write raw lua code using `lib.generators.mkLuaInline`. This function is part of nixpkgs.
|
|
```nix
|
|
vim.your-plugin.setupOpts = {
|
|
on_init = lib.generators.mkLuaInline ''
|
|
function()
|
|
print('we can write lua!')
|
|
end
|
|
'';
|
|
}
|
|
```
