Template:Install user script/doc

This template is used to install user scripts that reside on the English Wikipedia. It is to be used primarily on Special:MyPage/common.js or Special:MyPage/skin.js. It adds the necessary importScript line along with a backlink.

Usage

In order to install a user script for your Wikipedia account, add the following line to Special:MyPage/common.js or Special:MyPage/skin.js:

{{subst:iusc|script_path}}

• Replace script_path with the full .js page name of the user script to be installed.
• The template must be substituted (subst:), or else it won't work.
• Bypass your cache after saving the page.

Example

{{subst:iusc|User:TheDJ/sharebox.js}}

• Produces: importScript('User:TheDJ/sharebox.js'); // Backlink: [[User:TheDJ/sharebox.js]]

importScript() is not deprecated

There is some confusion about whether or not importScript() is deprecated. The answer is that it is not deprecated.

In 2015, importScript() was deprecated for one week, and then the action was reversed. In 2022, a bug causing importScript() to not work for mobile users was fixed. As of 2022, the latest statement by software engineers on the deprecation is phab:T27845#8135189, which states For local imports, call importScript(). This is not, and never was, deprecated. For cross-wiki and other less trivial use cases, call mw.loader.load().

In conclusion, importScript() is not deprecated, and editors should feel free to use it. It does not need to be systematically replaced by mw.loader.load(), and {{iusc}} does not need to be replaced with {{lusc}}.
