Yakuake is a top-down terminal for KDE (in the style of Guake for GNOME, Tilda or the terminal used in Quake).

Installation

Install yakuake, available in the official repositories.

Usage

Once installed, you can start Yakuake from the terminal with:

$ yakuake

After yakuake has started you can click on configure yakuake by clicking on the "Open Menu" button (middle button on the bottom right hand side of the interface) and select "Configure Shortcuts" to change the hotkey to drop/retract the terminal automatically, by default it is set to F12.

Yakuake scripting

Like Guake, Yakuake allows to control itself at runtime by sending the D-Bus messages. Thus it can be used to start Yakuake in a user defined session. You can create tabs, assign names for them and also ask to run any specific command in any opened tab or just to show/hide Yakuake window, manually in a terminal or by creating a custom script for it.

Example of such a script is given below. This includes opening tabs, renaming tabs, splitting shells, and running commands.

#!/bin/bash
# Starting yakuake based on user preferences. Information based on http://forums.gentoo.org/viewtopic-t-873915-start-0.html
# Adding sessions from previous website is broken, use this: http://pawelkoston.pl/blog/sublime-text-3-cheatsheet-modules-web-develpment/

# This line is needed in case yakuake does not accept fcitx inputs.
/usr/bin/yakuake --im /usr/bin/fcitx --inputstyle onthespot &

dbus-send instead of qdbus

You can replace qdbus bundled with Qt with more common dbus-send. For example, to show/hide Yakuake:

$ dbus-send  --type=method_call --dest=org.kde.yakuake /yakuake/window org.kde.yakuake.toggleWindowState
