[ANN] Rickshaw.js charting library for Seaside
by Esteban A. Maringolo 01 Oct '14

01 Oct '14

I just uploaded to SmalltalkHub an initial wrapper for the Rickshaw.js charting library (http://code.shutterstock.com/rickshaw/). As usual, you can load it with the following expression: Gofer it smalltalkhubUser: 'emaringolo' project: 'rickshaw'; package: 'ConfigurationOfRickshaw'; load. (Smalltalk at: #ConfigurationOfRickshaw) project development load: 'All' This will load all the packages, including a Seaside component installed at '/rickshaw' containing various examples. It is an initial version and my first package uploaded to SmalltalkHub, so bugs and and mistakes are expected :) Questions are welcome too. Regards, Esteban A. Maringolo

Checkbox and AJAX?
by Mariano Martinez Peck 08 Jul '14

08 Jul '14

Hi guys, I have this piece of seaside that renders a checkbox: renderCellFormContent: anObject on: html html form: [ html label:[ html checkbox submitOnClick; value: (self isSelected: anObject); callback: [ :value | self selectRow: anObject value: value ]]] That checkbox is actually one table cell of a row of a table (the first column) to select/unselect items. I would like to make this checkbox go with an AJAX request so that the whole page is not rendered and hence I loose scroll position etc.... So..what I need is that in the onClick of the checkbox I send an AJAX request. The checkbox of course should be updated and I also need to be able to continue executing the callback and the value. Any idea how can I do this in Seaside? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

debugging javascript within browsers is hard when the browser show the response on a single line
by Nick Ager 05 Jul '14

05 Jul '14

Hi, I wonder if other people suffer from the same problem when debugging javascript: Seaside's response is viewed by browsers as a string without line-breaks. Normally this isn't a problem as the browser "pretty-prints" the output when inspecting the html. However when debugging javascript, either inline or within a file-library the script debugger (I'm currently using Mac Safari) shows the output as a single line - which makes it impossible to interpret any javascript generated errors ("syntax error: line 1"!!) or to set meaningful breakpoints. I've discovered that calling #withInternetLineEndings on the file-library string results in browsers interpreting the line-endings as expected. Locally when I'm debugging I've created a class derived from WAHtmlDocument, which overrides #nextPutAll: WAHtmlDocumentWithInternetLineEndings>>#nextPutAll: aString super nextPutAll: aString withInternetLineEndings and I modify WAFileLibrary>>#handle: modifying the WAResponse>>#document: to: document: ((self documentForFile: fileName) withInternetLineEndings) Is there a better solution? Are there easier workarounds, browser settings etc. I created an issue for this problem: http://code.google.com/p/seaside/issues/detail?id=675 Though if there are easy workaround that I've missed, I'd be delighted to close the issue. Thanks Nick

Oauth without callbacks question
by Mariano Martinez Peck 30 Apr '14

30 Apr '14

Hi guys, I am trying to use OAuth (as a client) to a OAuth server in which the callbacks are a bit messy. So for the moment, assume I cannot specify a callback. So the only option I have right now (this is a prototype anyway) is to copy and paste the "verifier" so that I can later get the access token. I am basing my code in Sven's great Seaside demo. However, and here is the problem, he does this to go to the authentication page: self requestContext redirectTo: (self oauthService loginUrlFor: requestToken) ; respond. What happens here in my app, is that the browser redirects of course to the OAuth authorization server where I finally can see the verifier code. But...say I have to enter this code in my app...there is no way (as far as I understand) to map it to the (previously stored somewhere) request token. So I don't know which request token to use. So I think the only option is that the above redirect in fact opens another tab in the browser and that my seaside apps holds into the current request token. Somehow, I would like seaside to then ask for a verification code or something... Is that possible? Any idea how can achieve that? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

Pharo 3.0 Released!
by Esteban Lorenzano 30 Apr '14

30 Apr '14

Dear World, Pharo 3.0 (http://www.pharo.org) is here. The past year seemed short as we got busy building more than usual. Many things have changed in Pharo. Here are the highlights: - The new modular Opal compiler is now the default compiler used in the system. - The Athens vector graphics canvas is now integrated and it supports Cairo rendering on all platforms. - Many tools have been rewritten using Spec, a new framework for building user interfaces. - Versionner and Kommiter are two of the new development tools. - RPackage, a new package mechanism got enhanced with tags and is fully integrated in the system. - The debugger model was rewritten to become modular, the inspector received a bump to support multiple views, and the Nautilus code browser supports tags, search and lot more improvements. - Morphic has seen many cleanings and improvements and the visual theme has been revamped. These are just the more prominent highlights, but the details are just as important. We have closed 2364 issues in Pharo 3 (compared with 1727 issues in Pharo 2). Take a moment to go through a more detailed recount of the progress: https://github.com/pharo-project/ChangeLogs/blob/master/Pharo30ChangeLogs.md Pharo is improving on many fronts. Just take a look at the code city of Pharo (built with Pharo for Pharo). Every building is a class, and the red bricks represent the modified methods in Pharo 3. Many things are changing but the system gets more stable. Moving from Pharo 2 to Pharo 3 is almost a matter of just loading the code. Remember that Pharo is your platform. We thank all the contributors of this release: Jean-Baptiste Arnaud, Simon Allier, Philippe Back, Clément Bera, Alexandre Bergel, Torsten Bergmann, Usman Bhatti, Vincent Blondeau, Noury Bouraqadi, Johan Brichau, Camillo Bruni, Sven Van Caekenberghe, Damien Cassou, Nicolas Cellier, Guido Chari, Dimitris Chloupis, Bernardo Contreras, Ben Coman, Gabriel Omar Cotelli, Jordi Delgado, Tommaso Del Sasso, Gisela Decuzzi, Christophe Demarey, Sean DeNigris, Marcus Denker, Martin Dias, Erwan Douaille, Stephane Ducasse, Stephan Eggermont, Pablo Estefo, Luc Fabresse, Johan Fabry, Hilaire Fernandes, Nahuel Garbezza, Leo Gassman, Lucas Giudice, Tudor Girba, Thierry Goubier, Norbert Hartl, Dale Henrichs, Pablo Herrero, Nicolai Hess, Andre Hora, Alejandro Infante, Ricardo Jacas, Henrik Sperre Johansen, Denis Kudryashov, Pavel Krivanek, Juraj Kubelka, Laurent Laffont, Jannik Laval, Max Leske, David Lewis, Diego Lont, Esteban Lorenzano, Stefan Marr, Mariano Martinez Peck, Roberto Minelli, Hernan Morales Durand, Eliot Miranda, Fernando Olivero, Nicolas Papagna Maldonado, Nick Papoylias, Nicolas Passerini, Vanessa Peña, Nicolas Petton, Alain Plantec, Guillermo Polito, Damien Pollet, Jochen Rick, Benjamin Van Ryseghem, Ronie Salgado, Camille Teruel, Juan Pablo Sandoval Alcocer, Samir Saleh, Frank Shearar, Igor Stasenko, Aliaksei Syrel, Sebastian Tleye, Yuriy Tymchuk, Andres Valloud, Martin Walk, Hernan Wilkinson. And many many more who contributed indirectly, by reporting bugs, participating in discussion threads, providing feedback... Pharo 3.0 is the largest step we took since we started. Yet, it’s just a step. Expect more. Much more. Enjoy! The Pharo Team

Migrations - Object Database
by Aaron Rosenzweig 29 Apr '14

29 Apr '14

Hi, We’ve been experimenting with GOODS as an object database persistency mechanism for a couple of weeks. We plan to use Dali with it too. We’re really excited about this but have a burning question. Question: How do we handle changes to the “model” layer? Example: Suppose that last week we had a “Person” and “Profession” object. Each “Person” could only have one “Profession.” We’ve been saving some data to our Object Database and have 500 people and 25 professions currently saved and used with our app. This week we realize that our world view is wrong. Some people are both a “Chef” and a “Computer Scientist.” They have 2 or more professions. We must change our “model.” The class “Person” must change. How do we fix our object database now? Background: This isn’t really a GOODS specific question is it? I imagine it is the same issue with Magma, GemStone, etc. But in all the examples I’ve found nobody seems to talk about “migrations” or maybe I’ve overlooked it. Can someone point me in the right direction? In NeXT / Apple WebObjects I would write a “migration” to do the necessary steps to change SQL tables, make new DB constraints, etc. as an executable script. I would commit this migration to the repository. Any of the other developers on our team would automatically get it when they pulled from the repository. They don’t need to think about it. As soon as the WebObjects app launches the migrations would be run and they could see the new functionality and make “Marcus” both a “Chef and a Computer Scientist." When we deploy the new code in production, the migration will automatically run there too. This is all explained in detail here: https://github.com/wocommunity/wonder/blob/master/Frameworks/Core/ERExtensi… Any helpful pointers are appreciated. Thank you, AARON ROSENZWEIG / Chat 'n Bike e: aaron(a)chatnbike.com t: (301) 956-2319

ZnZincStaticServerAdaptor and debug
by François Stephany 27 Apr '14

27 Apr '14

I've started to use ZnZincStaticServerAdaptor but I can't get the behavior I want. When using > ZnZincStaticServerAdaptor startOn: 8080 andServeFilesFrom: (FileLocator imageDirectory / 'assets'). > ZnZincStaticServerAdaptor default server debugMode: true. I have a super simple root component that renders fine. But if I call a non existent method I get a 404 'Not Found'. ZnSeasideServerAdaptorDelegate>handleRequest: znRequest | response | response := self adaptor process: znRequest. ^ (response isError and: [ response isAuthenticationRequired not ]) ifTrue: [ self staticDelegate handleRequest: znRequest ] ifFalse: [ response ]. That explains the behavior. Is there a way to set a debugMode that does not trigger the fallback to the staticDelegate if the adaptor returns an error ? (opening a debugger would be great). Cheers, Francois

File download confirmation
by bobn＠rogers.com 27 Apr '14

27 Apr '14

Hello, I would like to add a confirmation to a file download. The problem I'm seeing is that my page does not refresh after the file download, so that any confirmation dialog is not cleared. Ideally I'd use an ajax callback to trigger the file download; the callback code does get triggered, but the file is not downloaded. I figure I'm missing something obvious. File download is using... self requestContext respond: [:response | response contentType: ... ] ...so I understand why the rendered dialog does not refresh, given that the response is not the page content. Using an ajax callback... onClick: ((html jQuery ajax callback: [self downloadMethod]) ... ) ...does not do the download, even though the download method is triggered. That also makes sense, since the requestContext is the ajax callback, not the page get. If that did work, I could use the javascript confirm. So, what this trick? ... I hate not seeing what should be a simple solution :-) Thanks for any help, Bob Nemec
