Chrome addon: Greasemetal – Greasemonkey for Chrome

Update: Greasemetal development has stopped since the new version of Google Chrome supports user scripts by default.

Chromium and Google Chrome (version 4 and higher) have built-in support for Greasemonkey-style user scripts.

To use, click on any .user.js file. You should see an install dialog. Press OK to install.

Known issues:
Chromium does not support @require, @resource, unsafeWindow, GM_registerMenuCommand, GM_setValue, or GM_getValue.
GM_xmlhttpRequest is same-origin only.

What is Greasemetal?

Greasemetal is a userscript runtime for Google Chrome. The runtime hosts userscripts (tiny javascript files that modify the webpages being displayed) to be executed on Google Chrome, similar to what Greasemonkey does for Mozilla Firefox, or Greasekit does for Safari.

How does it Work?

Google Chrome does not provide any interface to develop browser addons. Greasemetal modifies the behaviour of Google Chrome using an inter-process communication channel called AutomationProxy, which is used for automatically testing the functions of the web browser.

Using Greasemetal

To start using Greasemetal, download and execute the installer.
After installation, launch Greasemetal from the start menu. Greasemetal will in turn start up Google Chrome, while hooking its behaviours to insert userscripts.
Once you have started running Greasemetal, add userscripts to the userjs directory under your My Documents folder (or Documents folder on Windows Visa). If you are unfamiliar with userscripts, a number of scripts are available from userscripts.org.
