Just to throw in my gratz too, Nick, I also really like the recent template & quote & code changes, and so does my wife, Dragona. The template changes look great and seem like a really good idea in general. The most recent quote & code tag changes look really good and were probably overdue, especially the ability to attribute quotes directly. In short, good job! :)

It all works fairly well with the simplified method, so I won't bother doing either of those, thanks for the suggestions however. :-)

Glad everyone likes them.

Yup, a code tag is a new block element.

You could make .code a css class that has white-space: pre; and font-family: monospace; then change the php so it doesn't write <pre><code> tags, but a <div class="code"> tag...

A div will not nest inside of a <P> tag, so it will behave like the rest of the forum even when not nested.

Ah, why did it do that? I didn't give it permission to render the page that way.

A <code> tag must have an implied end of paragraph.

I remember now why it is hard to get quotes (or anything) going as a nested thing, using regular expressions. Basically regexp matches can be greedy or non-greedy, but neither one matches correctly on a message with both nested and non-nested quotes in it.


           [quote=Nick] aaa [quote=Willfa] bbb [/quote] [/quote]  [quote=Twisol] ccc [/quote]
greedy:    ^-------------------------------------------------------------------------^
nongreedy: ^-----------------------------------^
correct:   ^--------------------------------------------^


The greedy one goes too far, and the non-greedy one doesn't handle the nesting.

Now you could recursively descend into it (and then you have the problems of handling badly-formed messages) but this is something that has to happen on every post, on every page. (There are up to 15 posts a page).

I was worried about the overhead of doing that all the time.

The current system just blindly replaces form codes with html, eg. [b] becomes <b>.

One of many solutions I can think of is counting the number of start tags versus end tags
