[Help] Looking for unit tests and use cases for goodie and changeset fileout
by Jerome Peace 18 May '09

18 May '09

Recently on the Pharo list there have been some complains of loosing code when filing out change sets. In 3.10 changeset code was augmented to show which package catagory a method fell into. This is essential if coders are to know how MC and the changeset will interact. Those changes mucked with some of the fundamental ivar assumptions. And while I thought I caught them all I know of at least two that slipped by. To safely work on the code it would be nice to have regression tests in place. For that I would like to know if anyone thought of the use cases that need to be tested or any actual unit test code that might exist. What I am hoping for is for each type of thing that could be filed out, a way to test that changes to the code do not change the final fileout behavior. Then I can confidently do some refactoring. Yours in curiosity and service, --Jerome Peace

Setting desktop color.
by rvclayton＠acm.org 17 May '09

17 May '09

I've written a class method I use to configure new images. I'd like to have the method set the desktop set to black, but I can't figure out how to do that. I've looked at the changeColorTarget message in Morph, but after that I get lost in the ColorPickerMorph (which I'm guessing is unnecessary because the color's already picked). What is the code needed to set the desktop to black?

reading and writing from STDIN and STDOUT
by Jason Rogers 17 May '09

17 May '09

I am competing in a friendly Code Smackdown at work. Smalltalk vs. All on-comers (Haskell, Erlang, LISP, Java, C and Python). The challenge is to write a client for a Chinese Poker game. Everything is going well except communicating with the Python-based server. I am having trouble reading and writing from STDIN and STDOUT. I've installed OSProcess which should give me access to these streams, but I don't see how to read one line at a time from STDIN and then get a handle on STDOUT to write a line. Anyone have pointers or sample code? Also, the image needs to be launched by Python with code like... subprocess.Popen(["/Application/Squeak/Contents/MacOS/Squeak VM Opt", "/Users/jrogers/Squeak/images/chinese_poker.image", "Squeak Client"], stdin=subprocess.PIPE, stdout=subprocess.PIPE) This will obviously need to change for a server running on another OS. The question I have here is how to start a process reading from STDIN as soon as the VM is fired up. Should I just create an object that is waiting on STDIN, reading a line at a time, before saving the image? That way it would just keep trying to read when the image was fired up again. Thanks. -- Jason Rogers "I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me." Galatians 2:20

How to log in console in Windows
by Mariano Martinez Peck 16 May '09

16 May '09

Hi folks! I am calling a external shared library with FFI. This library does some puts(""); or printf(); In Linux, I open Squeak from command line and I can see the outputs of puts() and printf() in the console where I started Squeak. The problem is in Windows. I tried opening Squeak from cmd but didn't work. Nothing is shown in the console. Is there a way of doing this ? Thanks a lot in advance, Mariano

Very thanks, I forward to local Apple fellows. I afraid all is more expensive here Enviado desde mi iPod El May 15, 2009, a las 15:04, Joshua Gargus <schwa(a)fastmail.us> escribió: Do you have the option to get a Radeon 4850 instead of the GT-130? On the US apple store, it's $50 more, and about 3 times as fast as the GT130 (this particular NVIDIA GPU is old technology, rebranded so that they can sell it for more money). Unfortunately, it's not an option on the 2.66GHz configuration; I'd personally go with the 2.93GHz config upgraded with the 4850. Cheers, Josh Edgar J.

Re: Questions regarding FFI

I'm working in windows. If you are right then I think the only way to access the inline functions from Squeak (without recompiling the OpenCV dlls) is to compile a new dll which calls the inline functions and access this new dll from squeak. I will try that. Thanks! > > I don't have much of answers for you : > but for > > >* 3) Some OpenCV functions are declared as inline functions.
