nnn/plugins/README.md

Plugins extend the capabilities of nnn. They 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

The following command installs all plugins:

curl -Ls https://raw.githubusercontent.com/jarun/nnn/master/plugins/getplugs | sh

Plugins are installed to ${XDG_CONFIG_HOME:-$HOME/.config}/nnn/plugins. You can run the getplugs plugin 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.

Executing plugins

Method 1: Directly with :key:

export NNN_PLUG='o:fzy-open;p:mocplay;d:ndiff;m:nmount;n:notes;t:thumb'

With this, plugin fzy-open can be run with the keybind :o, mocplay can be run with :p and so on... The key vs. plugin pairs are shown in the help and config screen. Up to 10 plugins can have such keybinds.

Method 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.

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.

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.
