Custom Plugins

nvf, by default, exposes a wide variety of plugins as module options for your convience and bundles necessary dependencies into nvf's runtime. In case a plugin is not available in nvf, you may consider making a pull request to nvf to include it as a module or you may add it to your configuration locally.

Adding Plugins

There are multiple ways of adding custom plugins to your nvf configuration.

You can use custom plugins, before they are implemented in the flake. To add a plugin to the runtime, you need to add it to the vim.startPlugins list in your configuration.

Adding a plugin to startPlugins will not allow you to configure the plugin that you have adeed, but nvf provides multiple way of configuring any custom plugins that you might have added to your configuration.
