i3 - Unofficial Fork
This is a fork of i3wm, a tiling window manager for Linux. It includes a few additional features which you can read up on below.
If you want to check out how you could use them, you could check out my dotfiles repository.
This fork, much like i3 itself, maintains two branches: The gaps
branch is the equivalent of i3's stable master
branch while gaps-next
contains gaps
and i3's next
.
Installation
Please refer to the wiki to see how i3-gaps can be installed and for which distributions there are packages available.
Updating
You can update by simply switching into the directory of the repository and executing git pull
. Then rebuild and install via make && sudo make install
.
Please note that I do not care too much for backwards compatibility. At the time of installation, this readme will always be up to date. When I change something, I will update the readme as well. Before pulling, please check if something has changed and adapt your config / scripts accordingly. If there are any questions on how to adapt something, please feel free to contact me by opening an issue.

gaps
Note: Gaps will only work correctly if you disable window titlebars entirely. Unfortunately this is necessary due to the way i3 creates such bars on windows. You can disable them via for_window [class="^.*"] border pixel 0
in your config.
Based on the patches provided by o4dev and jeanbroid, i3 supports gaps between containers. I extended those patches further to make changing the gaps size easier during runtime and also to expose more functionality for binding it to keys. Additionally, the gaps patch was fixed such that the gaps between containers and the gaps between containers and the edge of the screen are the same. But I didn't stop there: these gaps are called "inner" gaps. This fork also allows setting "outer" gaps which inset all containers independently.
In your i3 config, you can set a global gap size as shown below. This is the default value that will be used for all workspaces:
gaps inner <px>
gaps outer <px>
```
Additionally, you can issue commands with the following syntax. This is useful, for example, to bind keys to changing the gap size:
gaps inner|outer current|all set|plus|minus
Examples
gaps inner all set 20 gaps outer current plus 5
Here are the individual parts explained:
* `inner|outer` specifies whether you want to modify inner gaps (gaps between adjacent containers) or outer gaps (gaps between the edge of a screen and a container).
* `current|all` determines whether you want to modify the setting for the current workspace only or for all workspaces.
* `set|plus|minus` allows you to either set a new, fixed value or make a relative change (in-/decrement).
Note that outer gaps are an *addition* to inner gaps, so `gaps outer all set 0` will eliminate outer gaps, but if inner gaps are set, there will still be gaps on the edge of the screen.
Additionally, gaps can be specified on a per-workspace level by using the syntax known from assigning a workspace to a certain output:
workspace gaps inner workspace gaps outer
It is important that these commands are specified after the global default since they are meant to override it.
Note that multiple such assignments are allowed (and perhaps necessary). The `ws` variable can either be a number or a name, so both of these are valid:
workspace 1 gaps inner 0 workspace "www" gaps inner 0
Here is one possible idea on how you can use this feature within your i3 config. Simply press `$mod+Shift+g` to enter the gaps mode. Then choose between `o` and `i` for modifying outer / inner gaps. In this mode, you can press one of `+` / `-` (in-/decrement for current workspace) or `0` (remove gaps for current workspace). If you also press `Shift` with these keys, the change will be global for all workspaces.
set $mode_gaps Gaps: (o) outer, (i) inner set $mode_gaps_outer Outer Gaps: +|-|0 (local), Shift + +|-|0 (global) set $mode_gaps_inner Inner Gaps: +|-|0 (local), Shift + +|-|0 (global) bindsym $mod+Shift+g mode "$mode_gaps"
mode "$mode_gaps" { bindsym o mode "$mode_gaps_outer" bindsym i mode "$mode_gaps_inner" bindsym Return mode "default" bindsym Escape mode "default" }
mode "$mode_gaps_inner" { bindsym plus gaps inner current plus 5 bindsym minus gaps inner current minus 5 bindsym 0 gaps inner current set 0
bindsym Shift+plus gaps inner all plus 5
bindsym Shift+minus gaps inner all minus 5
bindsym Shift+0 gaps inner all set 0
bindsym Return mode "default"
bindsym Escape mode "default"
} mode "$mode_gaps_outer" { bindsym plus gaps outer current plus 5 bindsym minus gaps outer current minus 5 bindsym 0 gaps outer current set 0
bindsym Shift+plus gaps outer all plus 5
bindsym Shift+minus gaps outer all minus 5
bindsym Shift+0 gaps outer all set 0
bindsym Return mode "default"
bindsym Escape mode "default"
}
### Smart Gaps
If you want gaps to only be used if there is more than one container on the workspace, you can use
smart_gaps on
This will disable all gaps (outer and inner) on the workspace whenever only one container is on the current workspace.
### Smart Borders
Based on the patch from [i3-extras](https://github.com/ashinkarov/i3-extras), smart borders have been added in a configurable way. If activated, this patch will draw borders around a container only if it is not the only container in this workspace. It is disabled by default and can be activated with the command below. `on` will always activate it, while `no_gaps` will only activate it if the gap size to the edge of the screen is `0`.

## i3bar
### Background & Color
i3bar now supports setting a background and border color for the individual blocks. Additionally, the border width for each of the four sides can be specified (where a width of `0` hides that border). Simply pass the following values via JSON to i3bar:
* `background` [color] sets the background color
* `border` [color] sets the border color
* `border_top`, `border_bottom`, `border_left`, `border_right` [int] width of the corresponding border (defaults to `1`)
Example:
{
"full_text": "example",
"color": "#FFFFFF",
"background": "#222222",
"border": "#9FBC00",
"border_bottom": 0
}
### Bar Height
The height of any bar can be configured to have an arbitrary value. This is especially useful if you plan on using top/bottom borders on status blocks to make the bar taller. If the height is not set, it will be calculated as normal. To set it, use the `height` directive in the `bar` configuration block:
bar { # height of the bar in pixels height 25 }
