Errors in WebLiveImage ?

Hi,

I took a look at Aida/Web code, and the first thing I should say is :
Wow!

Almost everything I need is already written, this framework is awesome,
well thinked and written! So much power and simplicity, very very good
job Janko, thanks for writting Aida ! I definitively love your work :)

I saw 1 or 2 stange things in WebLiveImage class :

First, in WebLiveImage>>refresh, the class Timestamp does not exist in
Squeak, the class is TimeStamp (and this is in lot of other methods).

Other strange thing : there are accessors for the instance variable
resolver, but this variable is not defined.

Cheers,

Nicolas

Thank you Nicolas! It is just too nice feeling when someone find your
work useful :)

Well, WebLiveImage (better word would be WebInstantImage, because it is
rendered instanlty, just before sent to browser) is not yet ported to
Squeak, because I don't have enough knowledge of Squeak graphics yet.
Otherwise you can see it in action here:

        http://demo.aidaweb.si/demos.html?view=liveImage

Actually it will become a SpTimestamp from Sport portability layer.
Migration of Aida to use Sport is not yet completely done.

Same reason - porting not finished yet.

Thanks for those remarks and I'm waiting you for more!

here.

BTW, in which Smalltalk dialect is Aida/Web (and Swazoo) written ? Which
one do Aida users mostly use ?

I think not, this part was most demanding to port, so I left it for a
future. Or for someone like you to help :)

Development started and it is still mainly in VisualWorks. I ported to
Squeak just recently, in June. Before was also ported to Dolphin. And I
just ported it to Gemstone and it will be part of forthcoming GLASS.

Most commercial use currently is on VisualWorks. Here in Slovenia exist
a company with 15 Smalltalkers doing Aida for logistic systems ...

Hi,

I found another strange thing in AIDASite class>>newNamed:

newNamed: aString
        | site |
        site := self new name: aString.
        Swazoo.SwazooServer singleton addSite: site.
        site initialize.
        ^site

Should "Swazoo." be removed ?

You  may want to consider using Cairo (in Squeak called Rome) to do the
graphics. That way you get high end vector graphics portable on both
systems.

I'm looking towards Cairo for a while, because of its multiplatform
support and especially to finally get a professionally looking graphs
onto my web apps.Something like:

        http://www.jfree.org/jfreechart/samples.html

Is a Cairo graphics in Squeak possible simply enough to conver to some
web format like GIF, PNG or JPG?

Best regards

Hi,

Do you know the javascript library plotkit ?

There is a seaside package (which includes some other things) :

You simply use the Cairo image backend (the default in Rome) to draw
onto a form and can then use the Squeak image writer classes to convert
it to the encoding of your choice.

Yes, but *please* don't mention namespaces on the Squeak-dev list ;-)

Yes I know, but for now I'm looking for more general graphics solution
and what Michael proposed is most general one: "to draw onto a form and
to use the Squeak image writer classes to convert it to the encoding of
your choice".

So, any takers to help extending WebLiveImage that way?

Best regards
Janko
