volumearc widet doesn't change color

[floli]

Hello,
I added the volumearc widget, control using the mouse wheel works, also mute / unmute on left click. However, the color does not change when muted. The pattern matching doesn't seem to be a problem:

The son and soff strings are the output of amixer -D pulse sget Master.

When am I supposed to find the definition of beautiful.widget_red? grep -R "widget_red" /usr turned up no relevant hits.

Disclaimer: I am both a lua and awesome newbie, so that there may be some trivial problem on my side involved.

Hi!
In this widget I used Awesome's theme capabilities. The idea is basically to put some variables inside your theme file (which by default should be /.config/awesome/themes/default/theme.lua).
So to make it work you can either

• add theme.widget_red=#ff0000 (or the color you like) in your theme.lua, or
• change it directly in the widget's code:

if mute == "off" then
    widget.colors = "#ff0000"
else
    widget.colors = "#00ff00"
end

But shouldn't this stuff be defined after

beautiful.init(gears.filesystem.get_themes_dir() .. "default/theme.lua")

?

Mm... not sure if I understood your question.
The variables used in widget (widget_red or widget_main_color) are custom - they don't exist in fresh Awesome installation. So if you add those variables in your theme.lua then they will be initialized by the line you pasted.

Ah, I see. I thought that beautiful.widget_red is supposed to be defined by default/theme.lua or one of the other themes, so there is a default /red/, defined by the theme, i.e. a color that draws attention and has a high contrast to the background color.
