[ANN] Wee 0.8.0

[Michael Neumann]

Hi,

Wee 0.8.0 is out. Have fun!

Major changes are:

* Ajax support (live updates). See examples/ajax/ajax.rb.

* FastCGI adaptor (working but not fully tested)

* Fixed bug in callback processing.

For example, you can update a field with Ajax like this:

def render
r.div.id('field')
r.anchor.onclick_update('field') { update_field }.with('Click here')
end

def update_field
send_render_response {
r.text "Live update works!"
}
end

More? http://rubyforge.org/projects/wee

Regards,

Michael

That is great news. Is there some configuration needed? When I tried the
ajax.rb I got the 1st page fine, but when I click on the "Helloooo" I got:
undefined method `+' for
nil:NilClassC:/ruby/lib/ruby/gems/1.8/gems/wee-0.8.0/examples/ajax/ajax.rb:
2 3:in `update'
C:/ruby/lib/ruby/gems/1.8/gems/wee-0.8.0/examples/ajax/ajax.rb:22:in
`with_renderer_for'
c:/ruby/lib/ruby/gems/1.8/gems/wee-0.8.0/lib/wee/core/presenter.rb:139:in
`send_render_response'

Oops, sorry. @live_updates is not initialize... use this patch:

--- ajax.rb (revision 602)
+++ ajax.rb (working copy)
@@ -20,7 +20,7 @@

def update
send_render_response {
- r.text "Live-updates works! This is no. #{ @live_updates += 1}"
+ r.text "Live-updates works! This is no. #{ @live_updates =
(@live_updates || 0) + 1 }"
}
end
end

Great news too!


Does this block-form of callback assume continuations? Is the other form:
r.anchor.onclick_update('field', :update_field }.with('Click here')
the non-callback version?

No, both do not involve continuations! The non-block form update_field) is
only for people that want to marshal the component state... blocks can't be
marshalled whereas symbols can.

Michael

Any idea what might be causing my wee rdoc to not appear (alongside the
rdoc for other gems in gem_server) in this version? It was there for
previous wee gems. It could be I did something foolish (I did remove some
wee directories I found in my regular non-gem ruby lib directories prior to
gem-installing 0.8.).

Simply because I did not generate the rdoc files for 0.8.0 (I had some not yet
ready-to-commit files in my tree that I did not want to show up). You can do
this yourself if you like with "rake rdoc".

Michael

How does one update multiple DOM nodes in a single liveUpdate?

Good question. No problem from the Wee side, but I am not good enough in
Javascript to implement this. What I thought is, that Wee would generate a
document like:

<root>
<div id="id1"> .... content .... </div>
<div id="id2"> ..... content .... </div>
</root>

This would update the DOM nodes id1 and id2 with the content.

Anyone willing to hack this in javascript?

Michael
