Kitti3 turns Kitty into a drop-down, Quake-style floating terminal for the i3 and Sway window managers.
- i3 & Sway native, flicker-free visibility toggling
- Multi-monitor support with adaptive resizing and alignment to the active monitor
- Flexible choice of terminal position; freely selectable dimensions
- Great responsiveness by leveraging the i3/Sway IPC API
- Support for multiple concurrent instances
- Kitty argument forwarding (e.g.
--session)
Kitti3 is a Python 3 package that lives on PYPI.
-
To install Kitti3, either:
- use pipx (recommended):
$ pipx install kitti3 - or use pip:
$ pip install kitti3 --user - or copy main.py
to somewhere on your $PATH, rename it to
kitti3and make it executable. (Note: in this case it's your responsibility to satisfy the Python dependencies)
- use pipx (recommended):
-
Ensure that Kitti3 is reachable (e.g.
$ which kitti3); the WM won't necessarily complain later if it isn't! -
Add the following to your
~/.config/<WM>/config:exec_always --no-startup-id kitti3 bindsym $mod+n nop kitti3where
$mod+nrefers to your keyboard shortcut of choice. Take a look at the configuration section below for a list of the CLI options thatkitti3accepts. -
Restart i3/Sway inplace (e.g.
$mod+Shift+r) -
Trigger the shortcut to verify that the terminal appears (slight flicker / tiling noise is normal on the first toggle when Kitty is spawned and floated by Kitti3)
Kitti3 does not make use of a dedicated configuration file, but its behaviour can be modified via commandline options:
$ kitti3 -h
usage: kitti3 [-h] [-n NAME] [-p {LT,LC,LB,CT,CC,CB,RT,RC,RB}]
[-s SHAPE SHAPE] [-v]
Kitti3: i3/Sway drop-down manager for Kitty. Arguments following '--' are
forwarded to the Kitty instance
optional arguments:
-h, --help show this help message and exit
-n NAME, --name NAME name/tag used to identify this Kitti3 instance. Must
match the keybinding used in the i3/Sway config (e.g.
`bindsym $mod+n nop NAME`)
-p {LT,LC,LB,CT,CC,CB,RT,RC,RB}, --position {LT,LC,LB,CT,CC,CB,RT,RC,RB}
where to position the Kitty window within the active
workspace, e.g. 'TL' for Top Left, or 'BC' for Bottom
Center (character order does not matter)
-s SHAPE SHAPE, --shape SHAPE SHAPE
dimensions (x, y) of the Kitty window, each as a
fraction of the workspace size, e.g. '1.0 0.5' for
full width, half height
-v, --version show kitti3's version number and exit
The name option provides the string identifier used to connect a user-defined i3/Sway
keybinding to the Kitti3 instance. Specifically, Kitti3 will listen to IPC events
and toggle the visibility of Kitty when it encounters the bindsym command nop NAME -
hence the requirement to include a "no-op" bindsym declaration in your config.
The name option value is also used internally to associate Kitti3 with the Kitty
instance it manages (the latter is forwarded the argument --name NAME). For this
reason it is worth ensuring that an instance name is chosen which is unlikely to collide
with that of another application's window; it would be wise to avoid the likes of
slack or discord.
The position option accepts a 2-char ID, which sets the Kitty window's location within the workspace (and implicitly in which directions to grow the window's dimensions). The window can be placed in one of nine locations:
| Left | Center | Right | |
|---|---|---|---|
| Top | LT | CT | RT |
| Center | LC | CC | RC |
| Bottom | LB | CB | RB |
The case and order of the characters are inconsequential (i.e. LB == bl).
Note that for backwards compatibility, the position option additionally accepts an older
location format, with the following mapping. The default position if none is provided is
actually right (refer to the note on shape below for why this matters). These choices
will be removed in a future
release.
| Old | New |
|---|---|
| top | LT |
| bottom | LB |
| left | LT |
| right | RT |
The shape option specifies the (x, y) dimensions of the Kitty window relative to its
workspace. Allowed values are in the range [0, 1], where 1.0 corresponds to the full
extent of the given workspace axis.
Note that for backwards compatibility, shape values will be interpreted in (y, x) order
when position is set to left or right.
The following i3/Sway configuration snippet produces a Kitty terminal positioned at the
center of the workspace, filling half its height and 30% of its width. It is assigned
the custom name "caterwaul", and the argument --session ~/.kitty_session is forwarded
to Kitty when it is spawned.
exec_always --no-startup-id kitti3 -n caterwaul -p CC -s 0.5 0.3 -- --session ~/.kitty_session
bindsym $mod+n nop caterwaul
Note that any arguments following -- are ignored by Kitti3 and forwarded to the
terminal when it is spawned.
Multiple Kitti3 instances (and hence Kitty windows) can be run concurrently; they just need to be distinguished by unique instance names to avoid crosstalk, e.g.:
exec_always --no-startup-id kitti3 -n almond -p CT -s 0.5 0.25
bindsym $mod+t nop almond
exec_always --no-startup-id kitti3 -n bubblegum -p CB -s 1.0 0.4
bindsym $mod+b nop bubblegum
Kitti3 must be respawned to trigger any changes made to its command line arguments in
the i3/Sway config file. This can most easily be achieved by restarting the WM inplace
(e.g. $mod+Shift+r), which because of the use of exec_always will spawn a new
instance of Kitti3. The old instance will automatically exit when it detects a restart
event, so you should not see any stray instances hanging around.
- Kitty (duh)
- i3 > 4 or Sway >= 1.6 (you should also be fine on the latest git)
- Python >= 3.6
- i3ipc-python (pip(x) will pull in >=2.0)
The following rant discussion was written some years ago and might not accurately
represent the current day lay of the land.
If you're not too fussed about which terminal you're using then there are several alternatives out there that do drop-down out of the box, like guake and tilda. However, if you find yourself wanting to experiment with fonts that support programming ligatures (like the excellent FiraCode), your options quickly dwindle as terminals based on the VTE library (like the two above) still don't play well with ligatures.
But you're here because you want to use Kitty, so forget about the natives for a second and instead ask yourself why you shouldn't just be using one of the other "drop-downifiers". Two notable mentions in this space are tdrop and i3-quickterm. tdrop is a swiss army knife that could probably turn a potato into a drop-down if you worked hard enough, but while feature rich it can be prohibitively slow and cause substantial flicker artifacts in i3wm during visibility toggling.
Kitti3 was actually inspired by the approach taken by i3-quickterm, which issues show/hide commands to i3 via IPC. It also supports other terminals than just Kitty, however its single-shot, mark-based design leads to some speed penalties and unwanted behaviour when spawning terminals. If you're open to using other terminals than Kitty (and have somehow made it this far into the readme), you should try it out. It was i3-quickterm's inability to display terminals as slide-ins (as opposed to drop-down or pop-up) that prompted the creation of Kitti3.
Kitti3 runs as a daemon and listens to events through the i3/Sway IPC API, using information about the active workspace to dynamically direct the WM in how to best resize and position Kitty when visibility is toggled. This leads to excellent responsiveness and no flicker artifacts, as well as a seamless experience in multi-monitor, multi-resolution setups.
"But I don't have a hundred external monitors on my desk!" you cry out. Well, if you're
running a single-monitor setup, or you're simply content with having the terminal
displayed on your main monitor only, then you don't actually need Kitti3 or any of the
other bolt-ons. The WM is happy to take care of container floating and positioning if
you're happy to work with absolute pixel values. This is where you start (add to
~/.config/<WM>/config):
exec --no-startup-id kitty --name dropdown
for_window [instance="dropdown"] floating enable, border none, move absolute \
position 0px 0px, resize set 1920px 384px, move scratchpad
bindsym $mod+n [instance="dropdown"] scratchpad show
and the i3 user's guide will lead you the rest of the way.
