Gnome Extensions - 运行shell命令

Question

I am writing a simple extension to open browser by clicking the extension button. I would like to know if there is a function which can execute passed shell command as argument. Also, it'd be really helpful if anyone can suggest a good simple reference for extension development.

From https://github.com/GNOME/gnome-shell/blob/master/js/misc/util.js :

// Runs @command_line in the background, handling any errors that
// occur when trying to parse or start the program.
function spawnCommandLine(command_line) {
    try {
        let [success, argv] = GLib.shell_parse_argv(command_line);
        trySpawn(argv);
    } catch (err) {
        _handleSpawnError(command_line, err);
    }
}

There are a few variations on that method in there. Save yourself mountains of headaches and just bookmark the GitHub repository.

Some quick links:

• popupMenu.js : working with popup menus
• panel.js : a good read for implementing "tray" icons
• modalDialog.js : some UI elements were made to be reused, runDialog.js uses this for example
• mpris.js : there are also good examples of using frameworks like DBus in gjs

I can't stress enough how much you'll get out of reading the gnome-shell source. Unfortunately, it's compiled into a resource file now so we don't have local copies to stumble upon.
