LJ New Comments working with Opera and with DreamWidth!

[marcmagus]

Thanks to a comment and link from pw201, the script maintainer, on my last post about the script, I've gotten the LJ New Comments GreaseMonkey script working correctly in Opera, and, further, working correctly in Opera with DreamWidth as well!

First, for full functionality in Opera using LiveJournal:

• Replace your GreaseMonkey Library Emulation script with mair_aw's modified version available here.

• Modify the New Comments script as described in my prior entry on the topic.

If you want to get DreamWidth working as well, you'll have to do a bit of extra work. Mair gave me the clue, that you need to get the GM emulation to set the correct domain in its cookies so the data can be retrieved again. Here are patches to both scripts to enable this. (I really need to get someplace to stick this sort of thing.)

For DreamWidth:

• Patch Mair's patched aagmfunctions.js with my patch (below) to provide API for setting a cookie domain.
• Patch LJ New Comments 1.3 with my patch (below) to use the domain API.
• Turn on the hidden '&nc=xx' feature at DreamWidth by visiting http://www.dreamwidth.org/settings/?tag=comment.

Comments/suggestions welcome.

Hopefully these will work ok, but aagmfunctions.js in particular uses tabs for indentation, which could easily get lost somewhere along the way. If you have any trouble, let me know and I'll send the raw patch.

Patch for Mair's modified aagmfunctions.js
