4chan Filter for Opera, Version 1.3a

Installation instructions

Set up an userscript directory for Opera. This option can be accessed using Tools -> Preferences -> Advanced -> Content -> JavaScript Options. After you’ve selected a directory, simply drop the .js file there and the script should load automatically.

Things to note

• All values are interpreted as regular expressions, meaning that some special characters will not work as expected when entered. Those are, for example, .+^$?*[]{}(). Such characters should be escaped with backslash unless you actually know what you’re doing.
• Since Opera doesn’t provide a way to store variables over a period of time, this script uses cookies to save settings. This means that a) if you disabled cookies nothing will work and b) if you set up Opera to delete new cookies on exit, all your settings will be gone the next time you start your browser.

Changelog

01/21/2009 – Version 1.0. Tested and working with Opera 9.6. Reports indicate it also works with Opera 10.

01/22/2009 – Version 1.1.

• Added toggle to sticky or unsticky control panel
• Fixed mouseover/mouseout for control panel
• All strings are precompiled to RegExps
• Added apply and reset buttons

02/01/2009 – Version 1.2. Improved support for fychan. Still some rough edges though. The post counter isn’t corrected after expanding a thread, and the `Reset page’ button destroys fychan. Nothing to be done about the latter since fychan always executes after this script.

02/02/2009 – Version 1.2a. Fixed new settings not taking effect unless the page was reloaded.

01/09/2010 – Version 1.3a. Updated some code which I don’t remember the significance of, and changed URL layout to conform to 4chan’s new URL scheme.

It adds some more advanced functionality like buttons to delete/report posts without having to go to the bottom of the page. With the current version it is also possible to `hide’ threads, a feature from the 4chan extension for Firefox that is sorely missed by Opera users.

Download: 4chan.js, 02/06/09

Has to be placed into your Opera UserJS directory, which can be set up under Preferences > Advanced > Content > JavaScript Options.

Full list of features

• Kills any iframes (you know who you are)
• Also kills any <embed> tags to prevent, for example, background sound caused by Flash objects.
• `Fixes’ quoting, that is, the comment box now properly advances to a new line after clicking on a post id. Also note that you can CTRL-click post ids to prevent the window from jumping up to the comment box.
• Adds buttons to delete, report and hide posts/threads.
• Also adds noko and sage boxes next to the e-Mail text control.

Notes on compatibility with fychan.js

The buttons to delete, report and hide posts do not work with fychan. Might or might not work on a fix for this in the future.
