This repo contains a crate for creating BitBar plugins in Rust.
Here is a simple example :
use rust_bitbar::{Line, Plugin, SubMenu};
fn main() {
let mut pl = Plugin::new();
let mut line = Line::new("first line");
line.set_color("red")
.set_href("http://google.com");
let mut sub_menu = SubMenu::new();
sub_menu.add_line(line);
let status_line = Line::new("🍺🍺🍺");
pl.set_status_line(status_line).set_sub_menu(sub_menu);
pl.render();
}
