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'.

Repository of petit parser

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

Create a .exe application in Pharo 2.0
by prova email Nov. 9, 2013

Nov. 9, 2013

It's quite hard to me to explain what i need. When i ask something, i've never had the answer that i want. What do you mean for "There are some places in the system where you can put txt file"? What are the places you are talking about? Is it the Pharo 2.0 folder? Can somebody tell me step-by-step how to create the .exe file? Why is it so difficult? As i said at the beginnning of one of my first messages, i'm a rookie in Pharo. So i need something more. Thanks again.Paolo

Pharo 3.0.0 dmg for Mac OSX
by Bruce Prior Nov. 8, 2013

Nov. 8, 2013

The dmg works for me now in OS 10.9 Mavericks. I didn't have "Allow downloads from anywhere" ON. If I launch Pharo2.0 I get a message, "cannot locate sources file." This isn't a problem for me. Thanks, Damien, for a cool launcher. Bruce

Well, it could be that your machine CPU too old and don't supports instructions (like SSE) which VM compiled with.

Spec - Text alignment in LabelModel
by nacho Nov. 7, 2013

Nov. 7, 2013

Hi, After spending almost two hours digging into Spec I couldn't figure out how to change the alignment of the text in LabelModel. As I'm building a simple calculator, the text has to be right-aligned. The default is left-alginement which makes the calculator display look weird. Any help would be much appreciated. best regards Nacho ----- Nacho Smalltalker apprentice.
