[Pharo-project] Standard input in Pharo?
by Andrei Stebakov May 5, 2012

May 5, 2012

I've been just going through "Computer Programming with GNU Smalltalk" book using Pharo 1.0 as an actual ST implementation. The book mentions "stdin nextLine" as a way to get an input from a user via the standard input. Is there a similar class/method in Pharo?

[Pharo-project] Help (perfect for newcomers) migrating a technical FAQ
by Mariano Martinez Peck April 10, 2011

April 10, 2011

Hi folks. I had a good idea and and it perfect for someone that wants to help and don't know how. It is not the most entertained task, but I promise you will learn a lot. Mostly, if you are newcomer. The idea is basically to migrate the FAQ that is here: http://scg.unibe.ch/wiki/faq/pharofaq to a new section in the collaborative Pharo book: http://book.pharo-project.org/ So....any takers ? Let us know so that we generate a new user in the Book The idea is also to check whether what is says is still correct for pharo or if it needs an update. Or even how to improve it (from the view of a newcomer). Thanks Mariano

[Pharo-project] Inspect it wrong shortcut
by Mariano Martinez Peck March 3, 2011

March 3, 2011

Hi! With latest pharo 304 in Linux the shortcut for inspect it (ctrl + i) doesn't work but alt + i. I have evaluated Preferences enable: #swapCOntrolAndAltKeys. Actually, all the other shortcuts (browse it, do it, explore it, and so on) works with ctrl + XXX but there is a problem with inspect it. Can someone confirm this ? Cheers, Mariano

[Pharo-project] CommandShell
by laurent laffont Jan. 28, 2011

Jan. 28, 2011

Hi, I'm trying to load CommandShell into Pharo. I have the error: This package depends on the following classes: PluggableTextController PluggableTextView You must resolve these dependencies before you will be able to load these definitions: ShellWindowView ...... Do you know where I can find PluggableTextController and PluggableTextView ? Or maybe we can use other classes to make it compatible with Pharo Cheers, Laurent Laffont http://pharocasts.blogspot.com/ http://magaloma.blogspot.com/

[Pharo-project] Using Pharo from the command-line
by Stefan Marr Dec. 2, 2010

Dec. 2, 2010

Hello: I just try to get started with Pharo to experiment with some benchmarks and would be grateful for some basic hints, since the documentation on pharo-project.org is not to excessive. As far as I read in the documentation of the language shootout[1], I will need the OSProcess package. How can I load this package into the image downloaded from p-p.org? My second problem is to execute code from the command line. I tried a simple example file $ cat test.sq Transcript open; cr; show: 'Hello, world'. $ Squeak\ 4.2.1beta1U.app/Contents/MacOS/Squeak\ VM\ Opt pharo1.0-10418-BETAdev09.08.3.image test.sq But this only leads to a debugger popping up in installSourceFile saying "No content to install". Looks like aStream is nil which should have the data loaded from file:test.sq Any pointers to documentation which might discusses command line related features are very welcome. I actually just need a way to choose a benchmark to be executed from the commandline. The actual code could already be in the image.

[Pharo-project] akuhn/SUnit: run faster tests first & step through tests
by Adrian Kuhn Oct. 23, 2010

Oct. 23, 2010

Hi Pharo list, The lastest akuhn/SUnit runs fasters tests first. When running your test suite for the second time, faster tests are run first. For the whole 9000 tests in the dev image, this means that the first 8000 tests are run in like 10 milliseconds. Also I fixed the menues in the test runner, you can now mark either all or single tests are expected defect. If you mark expected defects through the UI they are stored on the class side. The #expectedFailures method on the instance side is still taken into account for compatibility, but storing expected defects on the class side is the preferred way to do it now. I also cleared up the vocabulary. There are no more history on the class side, rather there are two histories one called "last run" and one called "expected defects" that both serve different purposes. The "last run" history is used to mark test results in the browser. The "expected defects" history is used to keep track of expected / unexpected defects. (As far I know, the icons in O2 show this as well.) Plus I added the ability to step through a failed tests. This stops right before the actual test method, rather than at the failed assertion. To step through a failed test, run your tests with the test runner and use the menu of test failures or errors. (OB and O2 might consider adding this option as well. In particular in combination with running fasters tests first a "run and debug/step-through first failure" might be interesting.) To load akuhn/SUnit gofer SystemChangeNotifier uniqueInstance noMoreNotificationsFor: TestCase. Gofer it disablePackageCache; squeaksource: 'akuhn'; package: 'SUnit'; package: 'SUnitGUI'; load. Thank you all for the awesome feedback last time! More is welcome :) --AA

[Pharo-project] is it possible to know the memory occupation (bytes) of an object?
by Mariano Martinez Peck Sept. 27, 2010

Sept. 27, 2010

Hi. I don't know if "memory occupation" is the better name. I just want to know the amount of memory that an object is occupying in RAM. I mean, the amount of bytes. Is this possible ? if true, how ? I would like to do it from both sides: image and VM. I checked both but I didn't find anything. Thanks in advance Mariano
