RubyBar¶ ↑

A bar for wayland implemented with Ruby and GTK. Configuration is done via a Ruby DSL.

RubyBar is in many ways similar to Waybar.
Both RubyBar and Waybar are gtk4 applications using gtk4-layer-shell.
However where Waybar requires static json-like configuration files RubyBar uses a pure-ruby DSL.
The DSL allows you to configure your bar programmatically.

You can even code your own widgets.

widget :power

widget :uptime, on_click: -> { spawn "alacritty -e htop&" }

widget :custom do
    @rand = Random.rand 100
    "random value '#{@rand}'"
end

widget :button,
    on_click: -> { `notify-send clicked` },
    class: "red" do
        "CLICK ME"
end

widget :load do |_, _, _, running| "tasks: #{running}" end

widget :systemd, user: true, service: "gammastep.service"
