[ANN] ShoreComponents 3 - back on Seaside
by Pavel Krivanek 17 Aug '07

17 Aug '07

Hi all, till now ShoreComponents used some special technological properties that helped to solve some general problems of Seaside applications. Unfortunatelly this properties cased that it was not easy to use ShoreComponents with standard Seaside applications. It was possible to use Seaside components in applications based on ShoreComponents but it was almost impossible to use components from ShoreComponents package as supplement of other components. So it was not possible to use it for cooperation with Magritte etc. The third major version of ShoreComponents makes big step in this area and I hope that it will be better and better. Main properies of the next release: - there's no base component class. Components are now based on standard WAComponent - components doesn't require parent reference. They can be created with classical "new" constructor - dynamic variables are used for navigation in hierarchy of components (for specification of target component etc.) - static files are now provided by standard FileLibrary This is the first alpha version so it's far from perfect. The main problem are some form processing issues so some components are not working well. Also nested forms problem is not solved now. Only platform independent part of ShoreComponents is converted now. I hope that you will find it useful and you will find motivation to improve and extend this set of components and use it in your applications. download: http://www.squeaksource.com/ShoreComponents/ -- Pavel

small seaside image
by Avi Bryant 25 May '07

25 May '07

A while ago I mentioned on this list a stripped 3.7-based Seaside image that was around 7.5MB. A couple of people have emailed me offlist asking for it, and I've finally gotten around to actually putting one up somewhere. You can grab it from: http://smallthought.com/avi/Seaside2.6.zip This includes Scriptaculous and is up to, I think, around 7.8MB now. Let me know if there are any problems getting or using it. Avi

CSS URLs
by Ron Teitelbaum 02 Feb '07

02 Feb '07

Hello all, Thank you everyone that has worked on seaside. Seaside is really a wonderful environment! I'm still getting my feet wet. I have a question. I would like to generate tabs that look like the attached html file. To do this I would need to be able to support a URL in css. I've got this working "IF" I translate the url to a seaside url. I see the generateUrlForDocument but the image tag needs context to generate the url. I figured I would parse and replace the urls in WAPresenter>>updateRoot: anHtmlRoot self script ifNotNilDo: [:script | anHtmlRoot addScript: script]. self style halt ifNotNilDo: [:style | anHtmlRoot addStyle: style]. This makes sense to me since it appears that the css is added for each change in session and the images hold their seaside url throughout a session. I also figured this was possible since I have the context in WAPresenter. When I tried to create an image WARoundedTabStyle image: #bg on: (WARenderCanvas context: self context callbacks: #()) (the image: imageName on: html method just does: ^html image fileName: imageName, '.gif'; mimeType: 'image/gif'; document: (self base64Decode: (self perform: imageName)) ) Creating a new canvas seems to have wiped things clean. Is there an easier way to generate and set the url of an image so that I can parse the CSS and replace url(some.gif) with the seaside url for that gif? Thanks for your help! Ron Teitelbaum

Kom redirect
by Nevin Pratt 13 Nov '06

13 Nov '06

Using Comanche with Seaside, how would one redirect http://www.mylocalhost.com to http://www.mylocalhost.com/seaside/home I know this isn't hard to do if I wish to change, say, WAKom (that's exactly what I did with an earlier version of Comanche). But I'd rather not touch somebody else's code. If Seaside was being fronted by Apache, the rewrite rule could be put into the Apache config, so it isn't a problem there either. But if I am using the latest version of Comanche? Is there a standard way to do this using Comanche/Seaside? Nevin

How to return input from in external (non-seaside) form to a WAComponent?
by Chuck Kasmire 07 Nov '06

07 Nov '06

I am trying to direct input to a form that is outside of seaside and then bring that form input back into the component that 'called' it. In my attempts at hacking this I have come up with: someActionMethod result := self session redirectTo: 'http:// localhost:8080/C:/formtest.html'). "this works" self inform: 'You entered: ', result contents. "this does not work" This in fact does bring up my form in the browser. But the 'inform:' part is never seen. I defined a subclass of WAEntryPoint and specified its path as: 'FormInput' In the form I defined its action as: action="http://localhost:8080/seaside/FormInput" method="get" In the WAEntryPoint subclass I defined: handleRequest: aRequest | response s | s := WriteStream on: String new. aRequest fields associationsDo: [:assoc | s nextPutAll: '#', assoc key, '=', assoc value; cr ]. response := WAResponse document: s contents mimeType: 'text/plain'. ^response 'response' is seen in my Browser. What seems to be missing is some sort of linkage between the session and the entry point. Such that the Response created in the entry point is directed back as an 'answer' to the origional call to the form. Am I on the right track? Any suggestions? Thanks, -Chuck __________________________________________________________________________________________ Check out the New Yahoo! Mail - Fire up a more powerful email and get things done faster.

new header api
by Philippe Marschall 03 Nov '06

03 Nov '06

Hi Now that both Seaside 2.7a1 and 2.6b1 have the "new" header API i think its time to write something short about it so people don't have to ask. The old header API was suffering from the same problems as the old renderer API. Just to add an stylesheet with media and title you had to copy and paste about 4 methods. Addional 4 for alternate stylesheets. If you wanted a new conditional import you needed to copy and paste a 3 LOC method. And so on. So we followed the same path like the Canvas API and made use of cascades. The new API offers four base methods to create elements - base, for base elements - if, for conditional imports - link, for link elements - meta, for meta elements - script, for script elements Most of the time will want to use one of these two convenience methods: - javascript, for javascripts - stylesheet, for css stylesheets See WABaseElement, WAConditionalComment, WALinkElement, WAMetaElement and WAScriptElement for details examples: aRoot stylesheet url: 'styles/blue.css' aRoot stylesheet document: 'a { color:red; }' aRoot javascript url: 'scripts/scriptaculous.css' aRoot if lessThan; ie7; do: [ aRoot javascripts url: 'iehacks.js' ] stuff that was just awkward to do with the old api: aRoot link beAlternateStylesheet; beCss; addProjection; addPrint; title: 'Blue'; url: 'styles/blue.css' Contrary to the Canvas renderer API the new header API in the background still used the old implementation. So you will have to implement no methods like #rendererClass. If you use the old API on Seaside 2.7a1 and have the development toolbar on you will get a warning pointing to where you use the old API. These methods include the code that you should replace yours with. Philippe

Swazoo versions
by Esteban A. Maringolo 02 Nov '06

02 Nov '06

Hi, Today I was playing with the published version of Seaside made by Avi Bryant the last week, which uses the Swazoo version for Dolphin made by Sean Malloy, to add some missing functionalities I had working in my earlier port of Seaside to Dolphin. Considering to what Sean says in his website, the port is based on the 0.9.101 version, while Steve Waring's one is based on 0.9.99 (apparently). Sean's version is more conscise in terms of number of packages, but it misses some classes such as SwazooSiteScript and other very useful tools, available in Steve's version. Considering that the Swazoo topic got warm this days, and that today it's more a jungle than a zoo ;-), we could arrange some efforts to make it converge into a single stream of development, at least compatible with what already exists in Dolphin. For example, you can't have Seaside and Spray web services running on the same image, because they're incompatible (besides the fact that the naming convention of Steve is different to the Sean's one*). Plus, Dolphin ships with Steve's version, which is appropriate considering the existing goodies and packages available, but not the best option aiming to a broader audience through Seaside and other popular developments that would come. I leave the topic here, to see if there is enough interest to make it happen. I would like to see Sean, Steve, Janko, the OA people, perhaps Bruce Badger too, and anybody willing to collaborate at least in testing, joining efforts for this. Best regards, -- Esteban. * Steve: I will be happy to know what SW, SV, and other prefixes mean. :-) ps: this is a cross-post to c.l.s.d, Swazoo and Seaside mailing lists, sorry for any inconvenience caused.

Seaside file upload oddness when file includes trailing cr
by Chuck Kasmire 01 Nov '06

01 Nov '06

Maybe this has been addressed somewhere but it seems that when I try to upload a file that has a trailing carriage return in it, seaside 'hangs' - waiting forever for a response. I am using (on Windows): Squeak3.8-6555full Seaside2.6b1-mb.79 Scriptaculous-lr.137 I have tried this with both Opera and Firefox with same result. In seaside going to '[tests], 'allcanvastests', 'upload': find a file that loads properly, then edit the file to add a trailing carriage return. Then try to load it. Seaside seems to 'hang' endlessly waiting... I hope this can be reproduced. Thanks, Chuck Kasmire __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Text in Header
by Brad Fuller 01 Nov '06

01 Nov '06

(I sent this to the smallwiki(a)iam.unibe.ch mailing list but it never showed up in my email. Don't know if the server is down.) Is there a way to easily change the text in the header of Pier to something different than the object created? When editing the environment/header I just receive the option to change the component type and it's name. Obviously, the concept is lost on me. brad
