Emulate the Greasemonkey GM_* functions for other browsers.
This script should not be not be installed directly. It is a library for other scripts to include with the meta directive // @require https://update.greasyfork.org/scripts/8068/36732/1%20Greasemonkey%20Emulation.js
In the uncommon situations where someone wants to run a userscript via one of the lesser-known methods other than Greasemonkey/Tampermonkey, one runs into trouble with scripts that were written to expect the availability of the Greasemonkey API GM_ functions. A few adept scripters have written emulation libraries for some of those functions. This is a copy of one of those libraries, which previously hadn't been posted on Greasyfork, with a few small modifications I made (added logging-only stubs for GM_setClipboard, GM_getResourceText, & GM_getResourceURL; commented out the outdated userscripts.org-based update code); the unmodified version is also available in this posting's history. In addition to the predecessors of this script mentioned in the author Lil Devil's notes below, the other similar libraries I found are: joeytwiddle's FallbackGMAPI (us-m, github) and arantius's Grant None Shim (us-m, github).

Script Name: Greasemonkey Emulation

Script Summary: Emulate the Greasemonkey GM_* functions for other browsers. A "user script" is a script that runs in your web browser to change, enhance, and alter the appearance and function on a given website. Firefox, Chrome, and Opera all support user scripts natively. Safari and Internet Explorer will run user scripts if you also install optional extensions.
A "Greasemonkey script" is a user script that was written for Greasemonkey (which runs in Firefox) and uses proprietary GM_ functions. Most user scripts (about 60%) do not use any GM_ functions, and will happily run in any browser that supports user scripts.
The remaining 40% of user scripts do use one or more GM_ functions, and if you want to run them in a browser other than Firefox, you need to use a Greasemonkey emulation script.
This emulation script is based on the Greasemonkey Emulation script by ale5000, which in turn was based on the Emulate GM functions script by TarquinWJ.
This emulation script will help make most Greasemonkey scripts work in the following browsers:
- Google Chrome 8 and newer, but you have to build an extension containing your Greasemonkey script and this emulation script.
- Safari 5 and newer, with NinjaKit. May also work with GreaseKit, but is untested.
- Opera 10 and newer
- Midori (untested, but the previous version worked, and my changes shouldn't have broken anything.)
In addition, this script will help make some Greasemonkey scripts work in the following browsers:
- Internet Explorer 8 and newer, with IEPro
This script will enable all GM_ functions in Internet Explorer, but IE does not support many basic JavaScript and DOM functions that many Greasemonkey scripts use, so some scripts will get errors and stop running. Scripts can be written to be compatible with IE, but many scripts written specifically for Greasemonkey will not work in IE without additional work. Please contact the original script author and ask him/her to make their script compatible with IE.
GM_ Functions
This emulation script emulates all of the following Greasemonkey functions:
GM_setValue
GM_getValue
GM_deleteValue
GM_listValues
- These functions use the best available of scriptStorage, localStorage, or cookies to save data.
GM_addStyle
- Works just like the Greasemonkey function.
GM_xmlhttpRequest
- Works just like the Greasemonkey function. To enable cross-origin requests in Opera, see the note below in the Opera section.
GM_log
- Works just like the Greasemonkey function. Logs a message to the console. If unable to find the console, uses an alert().
GM_openInTab
- Opens a new tab where possible, otherwise it opens a new window.
GM_registerMenuCommand
- Implements the "User Script Commands" menu as a pop-up menu in the lower-right corner of the browser window. The menu can be opened by pressing Ctrl-\ or by clicking your mouse in the lower-right corner. After it is opened the first time, a small "S" icon will remain visible.
GM_renameMenuCommand - Usage: GM_renameMenuCommand( oldCaption, newCaption, newAccessKey);
- Replaces the text of a menu command.
Please refer to the Greasemonkey API reference for more information on each of these functions.
Browser Notes
Opera [outdated information; use Violentmonkey or Tampermonkey for Opera now]Download the file, rename to aab-greasemonkey-emulation.js and put it in your Userscripts folder.
Internet Explorer [outdated information; use TrixIE WPF4.5 or GreasemonkIE now]
If you have another GM emulation script installed, such as aagmfunctions.js, you must remove it from the Userscripts folder.
To enable cross-domain GM_xmlhttpRequest, you must also install this script, however most Greasemonkey scripts do not need this.
In Opera 10.62 and newer, you should go to the opera:config page and set the "User JS Storage Quota" to a non-zero value. I suggest 5120. This enables user scripts to store private, cross-domain settings like in Firefox. If this setting remains disabled, user scripts must use localStorage which is not cross-domain, and can be read by other scripts.Download the file, rename to aab-greasemonkey-emulation.ieuser.js and use IE[7]Pro to install it.
Safari with NinjaKit [outdated information; use Tampermonkey for Safari now]Download the file, rename to aab-greasemonkey-emulation.user.js and put it in your Userscripts folder.
MidoriDownload the file, rename to aab-greasemonkey-emulation.user.js and put it in your Userscripts folder.
Google Chrome [outdated information; use Tampermonkey for Chrome now]This is a bit more complex than the other browsers. You need to build an extension. But it's really not that difficult. The first time I did it, I had to figure out what I was doing, and it took about 15 minutes. Now I can create an extension in less than 5 minutes. With these instructions it shouldn't take you much longer. To do.
