Seed (programming)

Seed is a JavaScript interpreter and a library of the GNOME project to create standalone applications in JavaScript. It uses the JavaScript engine JavaScriptCore of the WebKit project. It is possible to easily create modules in C.

Seed is integrated in GNOME since the 2.28 version and is used by two games in the GNOME Games package. It is also used by the Web web browser for the design of its extensions. The module is also officially supported by the GTK+ project.

This example uses the standard output to output the string "Hello, World".

#!/usr/bin/env seed

print("Hello, world!");

This code shows an empty window named "Example".

#!/usr/bin/env seed

Gtk = imports.gi.Gtk;
Gtk.init(Seed.argv);

var window = new Gtk.Window({title: "Example"});

window.signal.hide.connect(Gtk.main_quit);
window.show_all();

Gtk.main();

To use a module, just instantiate a class having for name imports. followed by the name of the module respecting the case sensitivity.
