To extend the capabilities of `nnn`, plugins are introduced. Plugins are scripts which `nnn` can communicate with and trigger. This mechanism fits perfectly with the fundamental design to keep the core file manager lean and fast, by delegating repetitive (but not necessarily file manager-specific) tasks to the plugins.
The currently available plugins are listed below.

## Installing plugins
Download the `getplugs` plugin and execute it anywhere to get all the plugins installed to `${XDG_CONFIG_HOME:-$HOME/.config}/nnn/plugins`. You can run it again later to update the plugins. It backs up earlier plugins.
**NOTE:** `getplugs` also downloads the launcher `nlaunch` and tries to place it at `/usr/local/bin/` using `sudo`. If it fails you have to place `nlauch` manually somewhere in your `$PATH`.
## File access from plugins
Plugins can access:
- all files in the directory (`nnn` switches to the dir where the plugin is to be run so the dir is `$PWD` for the plugin)
- the current file under the cursor (the file name is passed as the argument to a plugin)
- the current selection (by reading the file `.selection` in config dir, see the plugin `ndiff`)
Each script has a _Description_ section which provides more details on what the script does, if applicable.
## Usage
There are 2 ways to run plugins:
1. Directly with x-key:
export NNN_PLUG='o:fzy-open;p:mocplay;d:ndiff;m:nmount;t:thumb'
With this, plugin `fzy-open` can be run with the keybind xo, `mocplay` can be run with xp and so on... The key vs. plugin pairs are shown in the help and config screen. Up to 10 plugins can have such keybinds.
2. Use the _pick plugin_ shortcut to visit the plugin directory and execute a plugin. Repeating the same shortcut cancels the operation and puts you back in the original directory.
## Create your own plugins
Plugins are scripts and all scripting languages should work. However, POSIX-compliant shell scripts runnable in `sh` are preferred. If that's too rudimentary for your use case, use Python, Perl or Ruby.
You can create your own plugins by putting them in `${XDG_CONFIG_HOME:-$HOME/.config}/nnn/plugins`.
For example, you could create a executable shell script `git-changes`:
#!/usr/bin/env sh
git log -p -- "$@"
And then trigger it by hitting the pick plugin key and selecting `git-changes` which will conveniently show the git log of changes to the particular file along with the code for a quick and easy review.
## Contributing plugins
Please keep non-portable commands (like `notify-send`) commented so users from any other OS/DE aren't surprised.
The plugins should be executable. Please add an entry in the table above.
