starting a simple program - make EXE files for portable distrubution
by Hans Schueren Oct. 27, 2014

Oct. 27, 2014

Hello programmers , i am a beginner pharo. Now i have a complete , simple smalltalk program READY. The many functions of Pharo are not important for me at the time. What i want to do is the following : 1. starting the whole program in the Pharo environment ( not only a class or method ) 2. saving the image files only for the program in afolder. 3. storing the program image file on a USB stick. 4. starting and using the program on another PC. Theese questions seems to be simple for professionals. But let me explain the case. The program code in Pharo is included in all the classes and Methods. There is a package that contains many classes and different methods that represents the flow of the smalltalk program. During the writing i can check the methods and classes by sending a question to it and see the results. I have started a method by : method runmethod. or method new openInWorld. But what must i type to start the whole program ? If there are many classes ? How can i store the program in a optional image.file ? The program is indeed ready programmed. I have already realized that program code in Pharo is included in the image. Not as a file. Are there any online sites or instructions to do that ? Regards Hans

Is this the place for a Seaside question?
by Long Haired David Oct. 27, 2014

Oct. 27, 2014

I would like to know how to create a Seaside Server Adaptor using code. Can anyone give me a clue? I am using VAST 8.6 but I would have thought that it was fairly generic. ----- David Totally Objects Doing Smalltalk since 1989 -- View this message in context: http://forum.world.st/Is-this-the-place-for-a-Seaside-question-tp4786762.ht… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Starting a pool of worker images using command line parameters
by Esteban A. Maringolo Oct. 26, 2014

Oct. 26, 2014

tl;dr version: I'd like to be able to do something like $PATH/app/pharo-vm/pharo --nodisplay app.image st setup-worker.st --port 8091 and: $PATH/app/pharo-vm/pharo --nodisplay app.image st setup-worker.st --port 8092 etc. Do I have to define a subclass of STCommandLineHandler? How can I capture the --port argument? For what I saw, only "boolean" parameters can be defined (--quit, --save, etc, without arguments). It is, no getopts compatibility. Long version: For my apps I have a pool of worker images with Zinc+Seaside behind an nginx proxy. Each "upstream" (aka "worker") server, is started by supervisord, using a separate startup smalltalk script, where the only thing I change is the port of ZnZincServerAdaptor to start on a different port. The rest is identical. The startup is something like: $PATH/app/pharo-vm/pharo --nodisplay app.image st setup-worker1.st and for worker2: $PATH/app/pharo-vm/pharo --nodisplay app.image st setup-worker2.st and for worker3: $PATH/app/pharo-vm/pharo --nodisplay app.image st setup-worker3.st etc. Is there a better way to perform this without having to copy setup-worker1.st to setup-workerN.st for each worker image? How do you manage this? Regards, Esteban A. Maringolo

Embracing Morph
by Hilaire Oct. 26, 2014

Oct. 26, 2014

Hello, I fell like asking this question is ridiculous, but I can't see it in the Morph populations. I would like an owner Morph where I add submorph at random positions, then I want the owner morph to automatically shrink its extent to its submorphs. Apparently it does not exist. Am I missing somethings? Thanks Hilaire -- Dr. Geo - http://drgeo.eu iStoa - http://istoa.drgeo.eu

Slow at browsing
by Hilaire Oct. 25, 2014

Oct. 25, 2014

Hello, In Pharo 3.0 (and with Pharo 2.0), I noted an important slowness when browsing importantly populated class. For example, clicking on a method category of the Morph class, it takes about 3 seconds to reveals its methods. With Pharo 1.4 it is immediate with the same Morph class. My computer is a slow dog but it is not a good reason for this slowness. Hilaire -- Dr. Geo - http://drgeo.eu iStoa - http://istoa.drgeo.eu

Teaching fork

Here is a simple example about fork. Try the following : 10 timesRepeat: [ (Delay forSeconds: 1) wait. Transcript show: âhelloâ;cr]. Then the following : [10 timesRepeat: [ (Delay forSeconds: 1) wait. Transcript show: âhelloâ;cr]] fork. I think this should go in an introduction to Pharo. Annick
