This is part 3 of 3 about how to set up colors and fonts using .Xresourcess and syncing the settings in multiple applications.

In this video I apply the settings to polybar.

I have more videos about polybar, a good one to start with is:
#010: polybar setup https://youtu.be/7RNgpvBMua0

I filed an issue regarding fontsetting in polybar here:

mondo

These poison videos, inspired me to create my own theme manager called: mondo . By using mondo the processes shown in these videos can be done in a much more sober way, with more control and more flexibility!

You can find mondo on github:

.Xresources syntax

include file (OBS! quotes are important):
#include "RELATIVE_PATH"

define variable:
#define VARIABLE VALUE

custom resource:
name.class.resource: value/variable

---

on startup

shell

load .Xresources in ~/.xinitrc (recommended):

[[ -f ~/.Xresources ]]
&& xrdb -merge -I$HOME ~/.Xresources

#load .Xresources in ~/.config/i3/config:
set $HOME ABSOLUTE_PATH_TO_HOMEFOLDER exec --no-startup-id
xrdb -merge -I$HOME ~/.Xresources exec --no-startup-id exec i3-msg -q restart

If you have to load from i3 it's best to use

reloader script instead.

---

useful commands

shell

merge new changes:

xrdb -merge ~/.Xresources

replace .Xresources

xrdb -load ~/.Xresources

list current settings in .Xresources:

xrdb -query

list installed fonts:

fc-list grep FONTNAME

instant font test:

printf '\e]710;%s\007' "xft:FONT"

try using this font setting

:antialias=false

---

get resources

shell

use resource in i3:

set_from_resource $VARIABLE XRESOURCE DEFAULT_VALUE

use xresource in polybar:

VARNAME = ${xrdb:XRESOURCE:DEFAULT}

get xresource from script

VAR=$(xrdb -query awk '$1 ~ XRESOURCE":" {print $2}')
