String>>#base64Encoded
by Sven Van Caekenberghe 21 Mar '11

21 Mar '11

Hi, It took me quite some time today to figure this out and it might be relevant for others too: it turns out that String>>#base64Encoded introduces newlines which you definitively do not want when doing Basic HTTP Encoding for example. The tricky part is that it works when you stay below a certain length. This can easily be solved by invoking Base64MimeConvertor with the #mimeEncode: <string> multiLine: false Zinc HTTP Components now does this consistently through ZnUtils class>>#encodeBase64: Sven

Jtalk, a Smalltalk for web developers
by Nicolas Petton 20 Mar '11

20 Mar '11

Hi, I would like to share a project I'm working on on my spare time: Jtalk Smalltalk. http://nicolaspetton.github.com/jtalk https://github.com/NicolasPetton/jtalk Jtalk is an implementation of the Smalltalk language that compiles into JavaScript. Some features: - it is written in itself (including the parser/compiler) - it is self-contained - it compiles into efficient JS code - it uses the Squeak chunk format - Pharo is considered as the reference implementation I think Jtalk can be compared to CoffeeScript[1], Objective-J[2] or Clamato[3], from which it reuses some ideas and code. Jtalk includes an IDE with a class browser, transcript and workspace, an HTML canvas similar to Seaside and a jQuery binding. It is still a young piece of code, and some important features are still missing/incomplete. Cheers, Nicolas Petton [1] http://jashkenas.github.com/coffee-script/ [2] http://cappuccino.org/ [3] http://clamato.net

Submiting a form with a confirmation dialog (jquery) does not work properly
by Esteban Lorenzano 18 Mar '11

18 Mar '11

Hi, I'm trying to add a "confirmation dialog" using jQuery in a form, and calling submit from a jquery statement is not working properly (or at least, is not working as I was hoping to work). If I submit the form using javascript, I was expecting #defaultAction: to be called, but no :( Does anybody knows how can I do this properly? In the example, I render a dialog (with a form), then a form, and the "accept" button opens the dialog. The accept button in the dialog triggers my confirmation dialog and on complete submits the original form. This is the code: renderDialogCollectExtraInfoOn: html | dialogId formId dialogFormId | dialogId := html nextId. dialogFormId := html nextId. formId := html nextId. html heading level2; with: 'Collect extra information in confirmation dialog'. html div id: dialogId; script: (html jQuery this dialog title: 'Dialog with extra info'; resizable: false; modal: true; autoOpen: false; addButton: 'Accept' do: (html jQuery ajax serializeForm: (html jQuery id: dialogFormId); onComplete: ((html jQuery id: formId) call: 'submit')); addButton: 'Cancel' do: (html jQuery this dialog close)); with: [ html form id: dialogFormId; with: [ html checkbox on: #confirm1 of: self; with: 'Confirm 1' ] ]. html form id: formId; defaultAction: [ self halt. self inform: 'Ok'. "I'm expecting this to be executed" ]; with: [ html text: 'Some text: '. html textInput on: #text of: self. html button onClick: (html javascript add: ((html jQuery id: dialogId) dialog open); add: (JSStream on: 'return false'); yourself); callback: [ self halt. "I'm not expecting this to be executed" ]; with: 'Accept' ] Thanks, Esteban

Strategies for bulky renders/updates
by radoslav hodnicak 16 Mar '11

16 Mar '11

I've been using seaside with jquery to create quite interactive interfaces, using the simplest approach of "everything has its own callback". This works well if the dataset you're working with is small, but I'm now venturing into territories where it takes seconds to receive+render a page, which isn't acceptable. For an example of what I'm talking about imagine a page showing a list of emails. Every line (email) has a clickable sender, subject, date, and a bunch of more actions and icons etc. If you're creating anchors/click actions for each field separately, that's easily hundreds or thousands of callbacks per page, each needing to be generated on the server and sent over the wire. So clearly I need to instead write client side javascript that will figure out what the user clicked and do a parametrized request. Which I can do, but I'm wondering if someone has figured out a clever way how to map the information on the page to smalltalk objects on the server (other than using callback registry). Same goes for bulk actions involving multiple items ("delete selected" and the like). rado
