saving & uploading files?
by Tim Rowledge 29 Aug '02

29 Aug '02

I'd like to allow users to save certain info (like the results of a test, or a list of questions) to a file on their own machine or to upload a file (probably one saved previously). I see the IAFileUpload tag class, but it doesn't tell me a lot. :-( tim -- Tim Rowledge, tim(a)sumeru.stanford.edu, http://sumeru.stanford.edu/tim Let the machine do the dirty work. - Elements of Programming Style

AddressBook demo
by Tim Rowledge 22 Aug '02

22 Aug '02

Here's a little web addressbook I made today as a demo for somebody and (slightly altered) as part of my test-taker stuff. Feel free to add it to the release if you think it illustrates anything useful. Oh, it's for 0.93 since haven't had time to move to 0.94 although it doesn't use any explicit bindings so maybe it would just work? tim -- Tim Rowledge, tim(a)sumeru.stanford.edu, http://sumeru.stanford.edu/tim Useful random insult:- Dropped his second stage too soon.

Squeakers, I'm happy to announce the first release of Tantalus, an object-relational mapping framework for Squeak. At the link below, you'll find the framework itself, a couple of drivers, and some documentation. I'll be glad to here any feedback you might have. http://www.whistler.com/resources/about/software/ Cheers, Colin

progress

Hi folks, I'm about to take off on vacation for a couple of weeks, and I thought I'd say something about Seaside 2.0 before I go. I had hoped to release a decent preview before I left (and before ESUG), but it doesn't look like that's going to happen. But I'll tell you where we're at with it: - Seaside 2.0 will be a full reimplementation. A primary goal is to loosen up the paradigm and support a wider set of styles than the strict component/template model enforced by current versions. To achieve this, it's structured in a series of small layers. If you use all of the layers, you get something fairly similar to the current framework; however, you can choose to dump the top layers and go off in a completely different direction if you prefer. I'm actually quite curious to see if anyone does this. - The core layers are implemented and basically stable. I've been calling them, as a unit, "Borges". These include session management, html rendering with an event/callback system for forms and links, and a component system with snapshotting, embedding, and #callPage: similar to current versions of Seaside. What Borges doesn't include is any kind of high level presentation layer. However, it's an interesting base to play with, and would also be a good thing to start with for those interested in ports to other Smalltalks. Adventurous folk can get a snapshot from http://beta4.com/squeak/aubergines/source/Borges.st . There's not that much in the way of examples, but I'd be very interested in hearing comments from anyone who has time to play around with it. As for documentation, there's some information on the implementation at http://beta4.com/squeak/aubergines/docs/seaside/borges.html, but it is *not* intended for end users - it has more detail about the lower layers than most people will want, and doesn't cover components at all. - We're currently doing a lot of experimentation with presentation layers. Although a templating system is in the works, the interesting stuff (for me anyway) has been in programmatic specification of interfaces - last weekend, for example, Julian and I hacked out a Tk-like layout manager for HTML tables, and I've been playing with somewhat Morphic-like view classes for listboxes and such. We've also been playing around with web-based interface builders, using forms to specify connections between components and templates. These tools will eventually become "Marquez", the top half of Seaside 2, but right now they're totally in flux. I look forward to comments from y'all... Cheers, Avi

subcomponents with arguments?
by Ragnar Hojland Espinosa 08 Aug '02

I have something like this: ExShowCompany>>html ^ 'companydatahere <ExListPersons sea:id=persons></ExListPersons>' ExShowCompany has a companyID instance variable that gets called on object creation. ExListPersons lists all people along with their companies. What I want to do is, in ExListPersons, if companyID has been defined, dont write the companies column and obviously only output people who belong to companyID. The if I know I can do with, well.. if :) But how do I pass the value / call the companyID method of the ExListPersons component from inside the html template or similar? -- Ragnar Hojland - Project Manager Linalco "Especialistas Linux y en Software Libre" Tel: +34-91-5970074 Fax: +34-91-5970083

callPage question
by Rob Whitfield 06 Aug '02

06 Aug '02

Will bad things happen if my app nests a few levels down via cascaded "self callPage" and then the user clicks a link that takes them directly back to the top level page where they may begin to cascade back down again? I'm concerned about resource usage when the call stack is not properly unwound via "self return".

sexprs, newlines and brs .. is this a bug?
by Ragnar Hojland Espinosa 01 Aug '02

01 Aug '02

This works fine descr _ '<hello world>'. as in #html, the [descr] <> chars are correctly escaped. However, I have a multiline variable, with some newlines. Shouldnt they get escaped to <BR>s? I know I can add an escapeHtml: false to the addHandlers and get the contents through asHtml to escape them, but that looks more like a workaround than proper usage to me. Or is there some sexpr tag to escape the newlines? -- Ragnar Hojland - Project Manager Linalco "Especialistas Linux y en Software Libre" Tel: +34-91-5970074 Fax: +34-91-5970083
