Adjusting the size of a window using Spec
by nacho Nov. 10, 2013

Nov. 10, 2013

Continuing with my testing to learn Spec, I'm trying to build a really basic calculator. So far I managed to build the basic UI. However, I'm having some trouble at getting it displayed at the correct size. I don't know how to change the window that is opened when #ClassName new openWithSpec It seems that all the examples are opened with the same size. The image on the left is the "default" one, the one on the right is what I would like to get. I've tried by changing the width: of the column but that doesn't change the size of the window. I'm kind of stuck! thanks cheers Nacho <http://forum.world.st/file/n4719478/calc.jpg> ----- Nacho Smalltalker apprentice.

Spec - Nested Layouts
by Bahman Movaqar Nov. 10, 2013

Nov. 10, 2013

Hi all, Is it possible to nest layouts in Spec? For example can I combine `SpecColumnLayout` and `SpecRowLayout` together? TIA, -- Bahman Movaqar (http://BahmanM.com) ERP Evaluation, Implementation & Deployment Consultant PGP Key ID: 0x6AB5BD68 (keyserver2.pgp.com)

Seaside with scriptaculous updater
by Ezequiel Davidovich Caballero Nov. 10, 2013

Nov. 10, 2013

Hi! I'm new to the list (this is actually my first message and I signed up about an hour ago), hope somebody can help me with this and maybe this can help others too! Thing is I've been trying to do a webapp with pharo and seaside and I've been using scritaculous updater and ajax to display several components in the same page without reloading it all. To put some context on the subject, it's a form to send commands to a subsystem on a satellite simulator. You choose a subsystem from a drop down menu, then the other drop down menu updates it's contents with the commands understandable by that specific subsystem. Up until here, everything's peachy. Thing is some commands require parameters and for that I thought why not make several (several = number of parameters the command takes) text input boxes appear when the user selects the command? So I tried that, but it doesn't seem to be working. I know it's bit of a pain in the arse to read code from an email so I have the three methods (the main rendercontentOn, the one with the command list and the one with the parameters) in separate text files for readability. TL;DR: Why isn't my code working? Thanks in advance Ezequiel

I have two machines, both running Windows XP with SP3. On one of them I have a successful load of Pharo (actually it's a distribution of the Moose system, but that is just an application built on Pharo 2.0). This loads successfully when I double click on pharo.exe. On the other machine, the same action produces an immediate message: 'Pharo.exe has encountered a problem and needs to close'. Just in case this was some problem with Moose, I have just downloaded the latest one-click installation of Pharo 2.0 for Windows. This displays exactly the same behaviour - an immediate fail when I try to start it. > > I have tried to work out what may be different between the two machines. The one which will run Pharo has an Intel Celeron processor, the other an AMD Athlon XP (yes, they are both pretty ancient!), but I can't see why that should make any difference. The one curious thing is that Windows Explorer displays the type of the Pharo2.0.image file as 'Squeak image file'. There is an old version of Squeak installed on that machine; could that have any effect? > > I am a bit flummoxed by all this.

Looking at smalltalkhub there are plenty of PetitParser repos to find but none that looks official. So which is considered official? I still had Lukasâ repo in my config but the server seems to be down so I noticed. Norbert

rawSourceRanges in Encoder class question
by Gabriel Bursztyn Nov. 9, 2013

Nov. 9, 2013

Hi guys, I am new in this list.I have a question related to the sourceRanges dictionary in Encoder class. I can see every compiled method has each corresponding methodNode, which is an instance of a ParseNode child class. Every methodNode is formed by different parts represented by other classes also children of ParseNode, like AssignmentNode or MessageNode. when you decompile the method into the MethodNode, the Encoder instance saves the intervals corresponding to each of these parts. It not saves all the parts, just the AssignmentNode, MessageNode and ReturnNode. (other intervals like the ones corresponding to TempVariableNodes for instance are not saved). The weird thing is that it saves the intervals for the MessageNodes but for some reason they do not corresponds to the positions in the sourceText method (property of MethodNode). I read that this sourceRanges is used for debugging purposes, and I hadn't issues debugging my code. I do not know if it is a bug or I do not understand well the Parser class.I am using Pharo 2.0 and this code is also in squeak and cuis versions as well.Example: I have created an example class with the following method:ExampleClass>>#method1:method1 | a | a := 1 + (2 * 3). ^ a --- So if i inspect the rawSourceRanges:.. (ExampleClass>>#method1) methodNode rawSourceRanges, I have a dictionary with the following keys: a := 1 + (2 * 3). (AssignmentNode) --> 19 to 30 (so if i extract the characters from 19 to 30 in the sourceText I obtain the AssignmentNode text) 1 + (2 * 3) (MessageNode) --> 24 to 30 2 * 3 - (MessageNode) --> 28 to 29 ( it is not logic to have an interval for 2 characters if 2*3 (without spaces) has 3 characters. ^ a (ReturnNode) --> 34 to 35. So the ASsignmentNode and ReturnNode have their corresponding sourceText interval but from MessageNodes, I cannot see the same. Can anyone of you explain me why or if it is a bug? If you would like to watch a little more, the sourceRanges is filled in the Encoder class, when the Parser is parsing a method. thanks
