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 --commit`,
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.
To add a new plugin, run `./update.py --commit --add "[owner]/[name]"`.
