OneClickArchiver (source) – updated version of User:Evad37/OneClickArchiver.

• Works with the new section heading format.
• Fixes an issue with not finding the archive name.

To change the size of the "Archive" link, set the variable window.OCALinkSize = SIZE; in your common.js file; the default value is 0.6.

Hint: It's much easier if you get ScriptInstaller, then navigate to User:Elli/OneClickArchiver.js and click "Install" at the top.

However, here's the manual method:

1. Place {{subst:iusc|User:Elli/OneClickArchiver.js}} on Special:MyPage/common.js or a skin-specific page, like Special:MyPage/vector.js.
2. Clear your cache and enjoy!
