Tip for splitting renderOn: on multiple messages

Hello,

My renderOn: message become fat with times.
I try to cut in multiple parts.

Digging into sources, I found that following code is fine:

renderOn: html
html div with: [ self renderPartOn: html ]
...

renderPartOn: html
html ...

As renderPartOn: doesn't return anything, so return self, I don't understand in first approach how resulting tag could be inside parent tag (inner tag).
In fact, rendering a block, change the root tag to current tag, so html build new tag inside pseudo-root ! (and then restore root to original of course)

Is there a site/book/blog where I can find such tips or recipes ?

Vicnet,

not sure if I understand your comments correctly. But I think your thinking way too complicated. Look into the method with: it doesn't pass anything into tho block, nor does it use the result of the block's evaluation. It simply puts an opening div tag onto the html, evaluates the block and afterwards adds the closing tag onto the output stream. No magic there, no unwinding or tag hierarchy or anything.

You are right: with: just add tag and don't evaluate block

But I wonder how with: deals with inner tags.

html div with: ( self renderPartOn: html ) doesn't add inner tags inside div because () is evaluated before 'html div'.
html div with: [ self renderPartOn: html ] does the job (inner tags) because block is evaluated specifically (see *Web protocol for block) inside div tagbrush.
