Rxvt
====

`rxvt-unicode` is an advanced and efficient vt102 emulator. Here is a quick guide to configuration in both dom0 and guest VM.

Installation
------------

`dnf install rxvt-unicode-256color-ml` will bring both base `rxvt-unicode` and extension.
Let me also recommend excellent Terminus font: `dnf install terminus-fonts`.

Xresources
----------

In TemplateVM create file `/etc/X11/Xresources.urxvt` and paste config below.
`!`-lines are comments and may be left out.
`#`-lines are directives to CPP (C preprocessor) and are necessary.
This shouldn't go to `/etc/X11/Xresources`, because that file is not preprocessed by default.

Then create script to automatically merge those to xrdb.
File `/etc/X11/xinit/xinitrc.d/urxvt.sh`:

~~~
#!/bin/sh

[ -r /etc/X11/Xresources.urxvt ] && xrdb -merge /etc/X11/Xresources.urxvt

Shortcuts
---------

For each AppVM, go to *Qubes Manager \> VM Settings \> Applications*. 
Find `rxvt-unicode` (or `rxvt-unicode (256-color) multi-language`) and add.
