Introduction

Plugins extend the capabilities of nnn. They are executable scripts (or binaries) 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.

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:fzopen;p:mocplay;d:ndiff;m:nmount;n:notes;v:viuimg;t:thumb'

Now plugin fzopen 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.

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.

Running commands as plugin

To assign keys to arbitrary non-background cli commands (non-shell-interpreted) and invoke like plugins, add _ (underscore) before the command. For example:

export NNN_PLUG='x:_chmod +x $NNN;g:_git log;s:_smplayer $NNN;o:fzopen'

Now :x can be used to make a file executable, :g can be used to the git log of a git project directory, :s can be used to preview a partially downloaded media file.

Notes:

  1. Use single quotes for $NNN_PLUG so $NNN is not interpreted
  2. $NNN should be the last argument (IF you want to pass the hovered file name)
  3. (Again) add _ before the command

Access level of plugins

When nnn executes a plugin, it does the following:

  • Change to the directory where the plugin is to be run ($PWD pointing to the active directory)
  • Passes two arguments to the script:
    1. The hovered file's name.
    2. The working directory (might differ from $PWD in case of symlinked paths; non-canonical). Note that the second argument is not passed in case of commands starting with _.
  • Sets the environment variable NNN_PIPE used to control nnn active directory.

Plugins can also access the current selections by reading the .selections file in the config directory (See the ndiff plugin for example).

Create your own plugins

Plugins are a powerful yet easy way to extend the capabilities of nnn.

Plugins are scripts that can be written in any scripting language. However, POSIX-compliant shell scripts runnable in sh are preferred.

Each script has a Description section which provides more details on what the script does, if applicable.

The plugins reside in ${XDG_CONFIG_HOME:-$HOME/.config}/nnn/plugins.

Controlling nnn's active directory

nnn provides a mechanism for plugins to control its active directory. The way to do so is by writing to the pipe pointed by the environment variable NNN_PIPE. The plugin should write a single string in the format <number><path> without a newline at the end. For example, 1/etc. The number indicates the context to change the active directory of (0 is used to indicate the current context).

For convenience, we provided a helper script named .nnn-plugin-helper and a function named nnn_cd to ease this process. nnn_cd receives the path to change to as the first argument, and the context as an optional second argument. If a context is not provided, it is asked for explicitly. Usage examples can be found in the Examples section below.

Examples

There are many plugins provided by nnn which can be used as examples. Here are a few simple selected examples.

  • Show the git log of changes to the particular file along with the code for a quick and easy review.

     #!/usr/bin/env sh
     git log -p -- "$1"
    
  • Change to directory in clipboard using helper script

    #!/usr/bin/env sh
    . $(dirname $0)/.nnn-plugin-helper
    
    nnn_cd "$(xsel -ob)"
    
  • Change direcory to the location of a link using helper script with specific context (current)

    #!/usr/bin/env sh
    . $(dirname $0)/.nnn-plugin-helper
    
    nnn_cd "$(dirname $(readlink -fn $1))" 0
    
  • Change to arbitrary directory without helper script

    #!/usr/bin/env sh
    echo -n "cd to: "
    read dir
    
    echo -n "0$dir" > $NNN_PIPE
    

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.
