Re: [Pharo-users] Pratsch

Unlike in C/ C++ world where packaging creates an exe, Smalltalk has no packaged content for its program. Similar to Smalltalk is Java that packages its code / compiled bytecode as a jar . This jar can be "executable" but per se what it does is to start a JVM with loading of all the necessary dependent jars and runs the code of the "Program/ Application" jar. Smalltalk is a little different that we package the code for an application with all of its dependencies etc in the "image" file that contains the compiled bytecode of the code written. You just invoke the image with the pharo.exe vm engine viz: ************************************ >From a coder/ programmer perspective, it is quite a shift to understand that you do not have a standalone 5 line code that creates a "Helloworld" You write inside the IDE, the required class and method with its statement. The application packaging and delivery is a little more involved. So once you cross a barrier of understanding how to write code inside the IDE and see it running within the IDE with no visible "Compile - Run" cycle.

Polygons in woden

by Nicolas Lusa

Hi everyone, I am working on some 3d representation and I am trying to draw 3D polygons with woden. I actually manage to make "the walls" but I still have to implement top and bottom parts which are not so simple since the shape can be really different from case to case. How I am actually doing it is with: WDGeometryBuilder adding vertices with addP: N: C: TC: messages and with addQuadI1: i2: i3: i4: Furthermore I have some issues with the shadows which actually don't appear. You can see a current polygon created with the code that I made in the attached image. (also notice the shadows are missing as well as the bottom and top part of the polygon). [cid:E6905B6F-F5CA-447D-A42D-BA1604AC7F5A@mobile.usilu.net] Now my question is: is there already something that makes those polygons or does anyone have any hint on how to make the top part with woden? Thannks in advance. Cheers, Nicolas

Re: [Pharo-users] AST tokens question

by Mark Rizun

In the first place why I'm doing this. I work on Rewrite Tool and it's main functionality bases on replacing nodes in AST. Plus it works with sourceIntervals of nodes. Untill now my solution was: if I replace node, I reparse tree to get intervals updated However this solution brought new problems. Second reason is, that I think it makes sense to update interval of all AST if you replace one node. For example, we have: obj1 foo + obj2 bar and we replace obj1 with myObject. The interval of ast was 1 to: 19, and now it should be 1 to: 23.

Re: [Pharo-users] the simplest program of "the world"

by Werner Kassens

Hi Hans, i guess you are asking for a way to make a batch file that when double-clicked immediately starts your program? a batch file with something like this: ~/pharo3.0/bin/pharo ~/pharo3.0/shared/yourImage.image ~/pharo3.0/shared/start.st would do that. start.sh should be a text file with for example this: SystemWindow new openInWorld. werner

Pratsch

by Hans Schueren

Thank you Thierry , guess i am an user. " I have heared there are Pharo programmers" Can i download such a program to see how good they are ? I dont want to hear anything about coding and IDE and development. I am a user and want to start a example program. Do you have a LINK for me to download ? Hans This sounds strange. However , i have here a huge range of books about smalltalk 80. All the books describe the syntax and system. To write a better and better code and more functions. The only thing that is not describes is to display a running program inside image. The keywords and methods to display and save the own code inside the packages in the form of "image out" a manipulated smalltalk image to run as a user program. The first step is a really really simple program like mathematic calculation etc. But the procedure of end product must be clear. Only one good example perhaps with a transcript display can overcome theese difficulties. Its all unclear : show Transcript openInWorld class new class Theese commands are messages to a object. But the user does not input any program code. This is automatic running. Anyway , if the Pharo.exe started the image in the program. How , and with what keyword is then the program started fullscreen - which World is invoked to display? This preparation point is unclear when i want to make my "Allready written program" ready to start. However , i make a break with smalltalk now. A few books are still ordered from USA. If this point is unclear i cannot learn further at this point. It makes no sense to write Packages and classes if i cannot invoke the running arrangements No matter if they are objects or others.
