====== MATE Clock Applet Customization ======

Sometimes, you just don't like the standard clock MATE provides. I feel you... GNOME 2 were always a bit bland, so to speak, customization-wise. A blandness which seems to be shared with it's GTK3-compatible sucessor, MATE. As much as I like MATE, I'd like to be able to customize it a bit more. But, hey, GTK3 CSS and dconf-editor is here to help you. 

===== Custom clock format =====

Seems to be a somewhat recurring question, as I gathered when searching for it. It's really, really quite simple to do. There's a dconf key (which seems to echo me back the regedit-sh way of doing obscure things on Windows) which holds the custom format. You can browse it using ''dconf'' CLI utilitliy, but if you are incapable of using Terminals, fear not, just use dconf editor. 

tl;dr: navigate to: ''org.mate.panel.objects.clock.prefs'', where you can find two relevant keys: ''format'' and ''custom-format''. The former should be set to ''custom'' and, then, ''custom-format'' takes whatever you want to use. It uses the same standard substitutions of Unix [[man>date|date]] command. 

Mine, for e.g., is this: ''%a %b %e %Y,%_I:%M:%S %P'', which gives me ''Fri May 15 2020, 4:29:42 pm''. My system uses en-GB locale, so the %P comes in lower case, for whatever reason. 

==== Possible gotchas ====

On my ThinkPad, for some reason (perhaps oddities when carrying over an old Ubuntu MATE home to a Debian Buster installation) changing the ''clock'' folder (under objects) did nothing, instead the actual clock had another name, like ''org.mate.panel.objects.objectXX''. You'll have to dig it up. 

Also, sometimes, ''custom-format'' is a non-existant key. ''dconf write'' makes short work of this, but if you're using dconf-editor, you should obiously create it (but check where you are creating it, if the clock isn't in the correct folder). 

==== Quick and Dirty™ Script ====

<code>
#!/bin/bash
# Double check whate you are doing... I'm not responsible for 
# your cat going into hyperspace when you can't just do simple
# checks before running copypasta scripts from arround the web... 

OBJECT="clock"
FORMAT="%a %b %e %Y,%_I:%M:%S %P"

dconf write org.mate.panel.objects.${OBJECT}.prefs.format custom
dconf write org.mate.panel.objects.${OBJECT}.prefs.custom-format ${FORMAT}
</code>

I didn't test this. But should you mess up, it's just a matter of going to the applet preferences and setting it to 12 or 24 hours. 

===== CoLoRS and fonts =====

Sometimes you want your clock to be a little more colorful or, simply, to use a different font other than your system's default one. I do not use this hack anymore, so I don't guarantee it still works, but, hey, why not documenting it here? 

GTK3 has a neat feature: you can edit some UI elements by using CSS, which is rather useful. It's possible to use [[https://wiki.gnome.org/action/show/Projects/GTK/Inspector|GTK+ Inspector]], so you won't suffer trying to grasp which thing is which. It's still a bit painful, tho, because the GTK internals are **very poorly** documented, to say the least. 

As for the clock, I had the following lines on my ''~/.config/gtk-3.0/gtk.css'': 
<code>
#clock-applet-button
{
	background-color: black; 
	color: lime; 
	font-size: 9pt; 
	font-family: "OCR A Std"; 
	font-weight: bolder; 
}
</code>
(please don't fight me over the bracket thing)

Which gives you a rather ugly looking clock (given you have OCR A Std installed):

But, obviously, you can tweak it up. It was working here until some weaks ago when I, after installing Debian Bullseye (Testing), switched back to MATE and found this old ugly piece of config. I carried over some installations.
