OpenGLES2 binding available!
by Thibault Raffaillac July 28, 2016

July 28, 2016

Hi all, My tiny binding for OpenGLES2 is ready :) http://smalltalkhub.com/#!/~ThibaultRaffaillac/OpenGLES2/ It takes a different direction than that of NBOpenGL. I found the support for all versions of OpenGL overwhelming, both for beginners and to maintain. With a limited number of functions I could carefully name all messages. A demo using either SDL2 or GLFW (faster) is included, supporting VSync and retina displays. Tested only on Mac OSX, patches welcome! Cheers, Thibault

Good morning! Okey, so, i must create an object from Ghost? I am sendig all of you the data from cvs file. What I need is generate a code in Pharo for Read this information, (because i need work with the pays, or the credits notes), so I need, in a variable for example, put the value of the cell X, which contains the $Total. The information from csv file is like the next. I tried to use NeoCsv but i donÂ´t understood. Is good NeoCsv or is better the way using Ghost how you say?

Update CI books written in Pillar
by Yann Dubois July 28, 2016

July 28, 2016

Hi ! In the last version of Pillar (4.0.x), Pillar don't manage the compilation cycle. So the ./compile.sh does not work anymore. To update our CI, we use a Makefile (I advise you to use this too). You have an example on : https://github.com/pillar-markup/Pillar-Archetype/blob/master/welcome/Makef… . In this Makefile, we create symbolic links pointing on the output directory. It causes "out of memory" on Jenkins. To solve this problem, you need to remove the symbolic links after the compilation. Personnaly, I had *find book-result -type l -exec unlink {} \;* at the end of the EnterprisePharo's Jenkins script. Cheers, Yann

Hello, my name is Alejandro. IÂ´m writting code in Pharo 5.0. I need finish an exercise of my career. My question is: Â¿Could you tell me how can read and write a CSV File? I need the code, because i donÂ´t understand how is the use of NeoCSV or another tool for this. In the exercise, the text says: "You must Show the CashFlow por One Period with information from CashFlow.csv" Â¿How can I do this? Thanks!!!

Spec: Capturing changes in a text morph
by Offray Vladimir Luna CÃ¡rdenas July 28, 2016

July 28, 2016

Hi, I'm migrating my grafoscopio interface from I'm trying to capture some changes in a text morph that is part of a Spec interface. The interface is split in 4 parts, as you can see at [a]: (1) a main menu, (2) a tree, (3) a node header input text and (4) a text morph. When you click any node on the tree (2) the name of the node, called the header is shown in (3) and the node contents, called the body are shown at (4). If you made a change in the header (pressing enter) it's reflected back to the main tree. And the node's body is changed for a text morph [b] or a and embedded playground [c] according to tags in the node. So the reading part is working and I have some partial support for persistence, at least for node headers. [a] https://offray.withknown.com/2016/grafoscopio-notebook-interface [b] https://offray.withknown.com/2016/grafoscopio-text-node [c] https://offray.withknown.com/2016/grafoscopio-code-node Now I would like to extend the persistence for node's body content, so when any changes happens in the (4) panel, be it a text panel or a playground, it is stored in a similar way to what is happening with node headers and the (3) panel, but I'm unsuccessful trying to capture those changes. My initializeWidgets and initializePresenter are implemented this way: ================= GrafoscopioNotebook>>initializeWidgets windowMainMenu := self newWindowMainMenu. tree := TreeModel new. body := self newText. header := self newTextInput. body disable. body text: '<-- Select a node in the left panel'. tree childrenBlock: [:node | node children]; displayBlock: [:node | node title ]. ================= initializePresenter tree whenSelectedItemsChanged: [ :arg | arg isEmpty ifFalse: [self changeBody: arg ]]. header whenTextChanged: [ :arg | Transcript show: arg. (tree selectedItem content header) = arg ifFalse: [ (tree selectedItem) content header: arg. tree roots: tree roots]]. body whenTextIsAccepted: [ :arg | Transcript show: arg ] ================= I'm capturing properly the changes in text with whenTextChanged on the header but using the same message on body or whenTextIsAccepted doesn't produce any change on the trascript, and of course I can't update the any tree/node contents properly. Any advice on how to solve this will be greatly appreciated. If can happen soon in this week even better, because we could show this to our hackathon/workshop attendees. Cheers, Offray

Changing method definition at runtime
by Eric Velten de Melo July 27, 2016

July 27, 2016

Hello, One thing I try to do often is changing the behaviour of a method dynamically at runtime. The current way I do this is by having a block as an instance variable and having the method call this block, but I find this approach a bit cumbersome. Is there some other way or is this the recommended approach? I mean, I suppose methods could be changed dynamically by means of reflection somehow, but is this an easy or recommended way of programming in Smalltalk? Should slots make things easier? Eric

magritte extras
by Sean Glazier July 26, 2016

July 26, 2016

I am looking at creating a tool that works like the magritte example. It uses Magritte-XMLBinding. I ran the tests and had a small number of failures in Magritte-Tests-XMLBinding. The example class MADescriptionEditor is in the examples tag of the Magritte-Seaside package. It came from Repository: http://smalltalkhub.com/mc/Magritte/Magritte3/main/ and the XML binding for the examples comes from Repository: http://smalltalkhub.com/mc/Magritte/Magritte3Addons/main/ So if someone has these working and playing together that would be great. If it is outdated and we are to use something else I would like to know what the preferred way is so I can build the example building the descriptions using I guess json. Many thanks :-) Kind Regards, Sean Glazier

Pharo and GIT

Hi, can you point me to a latest (best) way to use GitHub for Pharo projects (Pharo 6)? Is the GitFileTree project the way to use it? How does ConfigurationOf change? Thanks! Juraj
