Is it possible to split Greasemonkey user scripts into multiple files?

Question

I'm creating a Grasemonkey user script that is getting really big.

Can I split it into several smaller files? If so, how?

Answer 1

Yes, and in Greasemonkey, it's rather easy. If you want to split your scripts into i18n.js, a utils.js and your main script body (and had them in that order in the original script), just change your script header to read something like this:

i18n.js:

var hello = 'bonjour!';

utils.js:

function say(msg) { alert(msg); }

my.user.js:

// ==UserScript==
// @name           My nifty script
// @namespace      Your unique author identifier
// @require        i18n.js
// @require        utils.js
// ==/UserScript==

say(hello);

…and Greasemonkey will download and install all three files, join them up in the order listed by your @require statements (main script last), and execute it as usual. Put them in the same directory on the server you distribute them from, or be sure to give full URLs in the @require statements to where they reside on the net.
