Herbstluftwm: A Dead Simple Window Manager

Herbs.....what? How do you even begin to pronounce this window manager? After some digging, it is apparently pronounced as the following: herbs + laugh + umm. And this is the version that makes the most sense! As to why it is named so:

I liked the name of the e-mail client wanderlust. Unfortunately I am a happy mutt user, so I needed an other application with a similar name.

  • the creator of herbstluftwm

Nevertheless, herbstluftwm is one of the easier window managers to get started with. The following is an index to help you navigate this blog easier:


Features

  • It is made for X11.
  • The layout is based on splitting frames to sub-frames.
  • Each screen (workspace) is called a tag, which has a unique identifier. Switching between tags is seamless.
  • It can be configured during runtime. Which means that any customization made does not require the service to be restarted.
  • herbstclient is the frontend for herbstluftwm, which can be used to issue commands to the server during runtime.

According to the herbstluftwm wiki, it functions in the following way:

                 startx
                   | f/e
                   V
              ~/.xinitrc
                   | f/e or exec
    IPC-Call       V
    .- - - -> herbstluftwm           __________________
  ."            /     \             | Symbol | Meaning |
  .            /       \            |--------+---------|
  .       f/e /         \ f/e       |  A     | A forks |
  .          /           \          |  | f/e | and     |
  .         V             V         |  V     | execs   |
  .     autostart       xterm       |  B     | into B  |
  .         |             |         |________|_________|
  .     f/e |             | f/e
  .         V             V
   --  herbstclient     $SHELL

In the last blog, we understood that startx loads the display manager, which in turn loads the .xsession and .xinitrc scripts to configure the X Client, which is herbstluftwm in this case. When started, it runs the ~/.config/herbstluftwm/autostart script to load all of the configurations.


Setting Up

Herbstluftwm is very easily to install, and will most likely have an installation candidate for your distribution.

sudo apt install herbstluftwm

To run it, simple add the following line in your ~/.xsession file:

exec herbstluftwm

Logout and log back in again, and boom! You are good to go.


Getting Started

Herbstluftwm then gives us access to spawn terminals using the default <Alt> + <Enter> command.

When we do that for the first time, the screen looks something like this:

Alt Text


Tags

Notice that the top bar has a few numbers, starting from 1 to 9. These numbers are tags (workspaces) that we can switch between. To do so, simply hit <Alt> + [1-9]. For example <Alt> + 6 will take me to the 6th tag. Note that whatever was running on the previous tag keeps on running there as usual. The highlighted numbers indicate that there is something running on those tags.

Alt Text


Windows

Herbstluftwm uses a lot of vim bindings for navigation. Here are some of the default key bindings for splitting windows and navigating:

Default key binding Action performed
<Alt> + o Split window horizontally
<Alt> + u Split window vertically
<Alt> + [h/j/k/l] Move left-right-up an down windows
<Alt> + r Terminate current window
<Alt> + <Shift> + c Terminate the process running in the current window
<Alt> + <Ctrl> + [h/j/k/l] Resize the window
<Alt> + <Shift> + q Logout
<Alt> + <Shift> + r Re-load configuration
<Alt> + <Shift> + [1-9] Re-locate the current window to another tag

Alt Text

Here the default super (called a modifier in herbstluftwm, or Mod) <Alt> can be changed by editing the configuration.


Herbstclient

The only way to communicate with herbstluftwm is by using herbstclient, which is a command line utility for inter-process communication with the WM server. To see the list of available commands, run:

herbstclient --help

It is a very powerful tool. In fact, the autostart file we mentioned earlier, has a lot of key bindings mapped to herbstclient commands. A simple example of how we can use herbstclient is:

herbstclient spawn firefox

This command will talk to the herbstluftwm backend to launch an instance of firefox in the current tag.

To learn more about how to use the client, go to the tutorial.


Configuration

All of the herbstluftwm configuration lies in ~/.config/herbstluftwm/autostart. This file can be edited for some of the following functionalities:

  • Adding keybindings.
  • Configuring colours and themes.
  • Changing the modifier key ( by default).
  • Configuring titlebar, borders, frame width etc.

And much much more. A simple example is the following:

hc keybind $MOD-b spawn firefox
hc keybind $MOD-n spawn nautilus

Here, hc is an alias for herbstclient, and $Mod is . This configuration essentially enables me to spin up firefox on hitting <Alt> + b and the file manager nautilus on hitting <Alt> + n.

The best part about herbstluftwm is that after changing the configuration, you don't have to logout to re-compile the program. Simply pressing <Alt> + <Shift> + r will reload the configuration with the changes made!


Verdict

Herbstluftwm is very easy to get started with. It has the capability to load the configuration during runtime, has a sophisticated client, and is extremely fast due to minimalism. I would recommend it to anyone who is getting started with window managers.

Maybe the author is joshing you. Herbst means autumn in German, and Luft is air. Wm is of course window manager. "Autumn air" sounds very romantic. 🙂

 

I was wondering how hard it could be for the author to look this up in a dictionary. Funny enough I read it Herbstluftwurm, as in atumn air worm, until I read your post, which to me made up for an even more poetic name. Anyway, technically reminds me of course of dlwm, which I have used a lot. I'll give it a try on WSL2)))

 

Hahaha 😄. Very intriguing name for a window manager

 

Doing taskbar in hlwm is challenging. And the extra frame almost makes me cry for happiness.

Quite an interesting read! Your configuration looks great.

 

I should say thank you for letting my article link in your comment section.

 

I have a blog coming on dwm soon. It will be a part of this series only :)
