Jiji is an i3-bar alternative. Written in Rust using gtk3-rs.
I wanted to have more controls on PulseAudio on the i3-bar. Existing alternatives do not provide much support. Fine, I'll write one.
I wanted to have richer controls on the bars. This excludes text-based implementations. I wanted to use languages with a package manager in order to utilize libraries easily. This excludes C/C++ based implementations (one can disagree on this). If there's an implementation that meets these conditions, I wanted to just utilize that, but I couldn't find one.
Hence, write my own one. In order to have rich controls, GTK seems a natural choice. Rust seems to have a good GTK binding. Here, i3-bar alternative written in Rust using GTK.
