nnn/plugins

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

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.

Contributing 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. 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.
