Converting a tricky recursive bit of BML code into Template Toolkit

[foxfirefey]

I'm posting this to show a conversion of an old recursive bit of BML code into Template Toolkit. It's from customize/advanced/layerbrowse.bml -- You can view the page here. The section in question is the right column under the "Classes" heading. It is a list of all of the classes in an S2 layer, in a hierarchical fashion where subclasses are under their parent classes. Warning: this post deals with things like recursion, so if it's all gobbledegook to you, do not worry and feel free to ask questions if you want.

( On to the example! )

Tell me what to do!

If there's a sesson on the OSCON schedule that looks like something you'd want to see the notes from, tell me about it, and I will go to the session and take notes on it! OSCON sessions are live-streamed, so if you want to watch one of them, you can. But if your schedule means you can't watch the stream, I will go for you. :)

(I do reserve the right to say "sorry, that conflicts with something I really want to go see", but still!)

Important: Perl 5.10 now considered required for DW installs

Hi all,

We're here at OSCON (O'Reilly's Open Source Conference in Portland) with a bunch of the volunteers who work on Dreamwidth. Related to this, we've finally decided to force an upgrade to our Perl base version required.

kareila says it well:

Hello all! A few facts have recently come to our attention:

1) Perl 5.10 has a significant number of new, desirable features over Perl 5.8.

2) Perl 5.10 was released 5 years ago, so it's reasonable to assume most people are using Perl 5.10 or newer in production.

3) We are, in fact, using Perl 5.10 in production.

Therefore, we are planning to start requiring Perl 5.10 as we fix bugs and add new features in the future. If you are running a Dreamwidth installation on a version of Perl older than 5.10, now would be an excellent time to consider upgrading.

We are also considering moving to 5.12 or 5.14 soon. We need to do some more investigation and also validate the system on those versions. But for now, consider 5.10 as required.

Thanks!
