Popup/Quake style terminal for Haiku OS

qterm-toggle.sh

#!/bin/bash

### the unique window title prefix for our terminal session
terminalKeyword="QuakeTerm"

### optionally set the location of a custom terminal profile to be used
### it must contain whatever is used as the terminalKeyword at the beginning of the "Window title"
### for example:    "Window title" , "QuakeTerm %i: %t"
### comment out the line to use the default Terminal settings
#terminalProfile="/boot/home/config/non-packaged/apps/MyCustomTerminalSettings"

### position the terminal up against the top of the screen towards the center
### x,y coordinates can be any side or location
windowLocation="200,0"

### override the whole window frame with coordinates left,top,right,bottom
### if both windowLocation and windowFrame are enabled then only windowLocation will be used
#windowFrame="200,0,1200,600"

### watch and minimize the window even if it was activated by Deskbar/twitcher/....
### otherwise only auto-hide if it's been activated by this script
### comment out the line to disable
#continuousWatch=1

### how frequently should we check the status of the window
### lower numbers give faster response and can be decimal numbers like 0.5,1.5,2.2,...
