[REQUEST] Compatible with xrdb values (Xresources colors)

[Angel-Karasu]

Before opening a feature request

• [X] I checked the next branch to see if the feature has already been implemented
• [X] I searched existing reports to see if it is already requested.

What is the user problem or growth opportunity you want to see solved?

The user can't use xrdb setted values (in the Xresources file)

How do you know that this problem exists today? Why is this important?

Because I can't use my xrdb setted values

Who will benefit from it?

For all users that have configure colors or any others value in Xresources file

Rofi version (rofi -v)

1.7.5

Configuration

https://github.com/Angel-Karasu/dotfiles/blob/main/config/rofi/config.rasi

Additional information

The format can be:

mycolor: ${xrdb:name};

With ${xrdb:name} that use the value return by xrdb -get name.

For example, for me xrdb -get background return #121212 that I want to set this color in mycolor.

I'm willing to help implement it but I haven't managed to understand how the parser works.

something like this would be kinda ok to me, but it might not be handy for @lbonn wayland port.

[Angel-Karasu]

Normally xrdb -get name it's also available on Wayland (it works for me in VM on qtile wayland with EndeavourOS)

[DaveDavenport]

Yeah, but that uses xwayland I assume. If this would be implemented, it should be done via libxcb library (as done in very old versions of rofi), this would be difficult in wayland port as I don't think that has it, or access to the required underlying interface.

I don't think it is good to have it depend on both.

You could always wrap rofi and set environment variables for colors, this you can use in themes.
