In i3 configuration, keybindings are defined by the bindsym keyword, and the modifier ( by default) is defined by $mod. See the full configuration tutorial for i3 here. In the next section we will learn how to add gaps between windows in i3. In this blog, we will be configuring our status bar as well as changing some key bindings to get started. All of which are well documented on i3's official user manual. It uses an easy to use syntax for defining parameters. The i3 configuration lies in ~/.config/i3/config file. Tabbed mode is exactly like the stack mode, the only difference being that it visually places the windows as tabs (the kind you might see on a browser). Note that it is not actually a stack internally, but only visually so. Stack mode will place each and every tab on top of each other like a stack. Note: You can switch between horizontally and vertically split panes using + e toggle After this mode being activated, when you spawn programs next, either using shortcuts or dmenu, they will be horizontally split. This mode is used for spawning windows which are horizontally split. After this mode being activated, when you spawn programs next, either using shortcuts or dmenu, they will be vertically split. This mode is used for spawning windows which are vertically split. For example, in the given window split pane, the tree will look like the following: Now you have different modes of operation, and each mode tweaks the layout, but all in all it is just a tree data structure underneath. Traversing through these windows is just like tree traversal. Turn on tabbed mode (explained in the next section)Īs mentioned earlier, i3 uses the tree data structure for storing window references in workspaces. Turn on stacking mode (explained in the next section) Re-locate the current window the tenth wprkspace Re-locate the current window to another wprkspace Split window horizontally on the next spawn Split window vertically on the next spawn The only difference is that instead of using h|j|k|l for movement, it shifts the bindings one key to the right and instead uses j|k|l|. Note that whatever was running on the previous workspace keeps on running there as usual. For example + 6 will take you to the 6th workspace. To do so, simply hit + for the first 9 and additionally + 0 for the 10th workspace. I3 gives you 10 workspaces that we can switch between. In i3, the status bar shows the number of active workspaces. When we do that for the first time, the screen looks something like this: But this can of course easily be configured. Yes, i3 status bar is at the bottom by default. Once you do that, you will be greeted by your wallpaper, with a thin status bat at the bottom. Which will prompt you to generate a configuration automatically: The first time you run i3, since you will not have a configuration template at ~/.config/i3/config, i3 will run the i3-config-wizard. Logout and log back in again, and boom! You are good to go. The easiest way to get started (on debian based systems) is this:Įnter fullscreen mode Exit fullscreen mode In addition, you can download the debian release, or just the tarball as well. I3 is available for the following distributions. Now I don't know about you guys but I think this is targeted at dwm for enforcing a 2000 SLOC limit on their development. If it needs to be a bit bigger, it will be. However, we do not enforce unnecessary limits such as a maximum amount of source lines of code. The usual elitism amongst minimal window managers: Don’t be bloated, don’t be fancy (simple borders are the most decoration we want to have). One thing to note is the following statement clearly mentioned on their official website: It uses the asynchronous XCB library instead of the old, synchronous XLIB.Ĭheck out the I3 guidelines on their official website.Which means that any customization made does not require the service to be restarted. I3 assigns each workspace to a virtual monitor, thus implementing multi-monitor functionality correctly.Which we will see in the upcoming sections. I3 uses the tree data structure for storing window references.Primarily due to its beautiful and well maintained documentation (some of the best docs I have ever seen for window managers), as well as an advanced user community who regularly chip in to make sure things keep running smooth. The developers claim that it is targeted towards advanced users, but it is certainly easy to use and configure. One of the most popular tiling window managers out there, i3 is written from scratch.
