I am playing around with Seaside 3 and noticed that, for example:
html paragraph: 'text', and html paragraph: [html text: 'hello']. Are both valid. When I looked at the definition for paragraph: it says that takes a aBlock, but then doesn't seem to do a value: aBlock. So, what I am wondering is whether it is valid to give a string as a block, or whether this is just a slightly loose definition of block?

As I recall, the seaside things that have contents accept "renderables", which is anything that understands #renderOn:. Seaside monkey-patches Object to ensure that *everything* has a #renderOn:, but there are special overrides for Collection, String, and, as you've discovered, BlockContext. Browse all implementors of #renderOn: for more illumination. -- Randal L.

Andy,
a string and a block are two distinct things in Smalltalk. Seaside just lets you provide one or the other as an argument for messages like paragraph: because that's convenient when you write a web application. Sometimes you want to have plain text in that paragraph, then you use html paragraph: 'some text'. Other times you want to nest more html structures inside the paragraph, then you do something like html paragraph: [ html span class: 'highlight'; with: 'more text' ] or, maybe more illustrative of the idea: html table: [ html tableRow: [ html tableData: 'cell 1'. html tableData: 'cell 2' ]. html tableRow: [ html tableData: 'cell 3'. html tableData: 'cell 4' ]. ] Somewhere in the Seaside code there is a dispatch that processes strings and blocks differently.

This is a question better suited to the Seaside mailing list...!

I just wanted to make sure I hadn't completely misunderstood blocks! Cheers Andy _______________________________________________ Beginners mailing list [hidden email] http://lists.squeakfoundation.org/mailman/listinfo/beginners |
