How to convert a bookmarklet into a Greasemonkey userscript?

Is there a easy way to do this. And is there anything that needs to be changed due to differences in how it is ran?

Solution

  • The easiest way to do this:

    1. Run the bookmarklet code through a URL decoder. so that javascript:alert%20('Hi%20Boss!')%3B, for example, becomes:
      javascript:alert ('Hi Boss!');

    2. Strip the leading javascript: off.   Result: alert ('Hi Boss!');

    3. Add this code to the end of your Greasemonkey file. For example, create a file named,
      Hello World.user.js, with this code:

      // ==UserScript==
// @name            Hello World!
// @description     My first GM script from a bookmarklet
// @include         https://stackoverflow.com/questions/*
// @grant           none
// ==/UserScript==

alert ('Hi Boss!');

    4. Open Hello World.user.js with Firefox (CtrlO ).   Greasemonkey will prompt to install the script.

    5. Now the bookmarklet code will run automatically on whatever pages you specified with the @include and @exclude directives.

    6. Update: To ensure maximum compatibility, use the @grant none directive that was added in later versions of Greasemonkey and Tampermonkey.
