Re: [Pharo-dev] XPath chapter...

by J.F. Rick

NICE! I was just using XPath for Selenium testing. It is really great for that application (commanding a browser like Firefox or Chrome to simulate user actions). What are the applications for XPath in Pharo? Unit testing of generating markup? Cheers, Jeff PS After spending significant time with other languages at work, I really have an appreciation of how wonderful Pharo is as a development environment.

Primitive Failed error trying openInExternalWindow

by Eduardo de Oliveira Padoan

Hi, greetings! I was trying out some examples from the Pharo By Example book on the latest development version of Pharo, and I wanted to create a stand-alone window for a simple game on Ubuntu. So I found out the openInExternalWindow method, the window appears but I get this error that I couldn't understand, and could not find any reference to it online. So I'm not sure if it's a bug. The simplest way I found to reproduce it was: 'Hello' asMorph openInExternalWindow. I'm using Pharo 7 on Ubuntu 17.10. A copy of the stack: ByteArray(Object)>>primitiveFailed: ByteArray(Object)>>primitiveFailed ByteArray>>integerAt:size:signed: ByteArray>>unsignedLongAt: SDL_KeyDownEvent>>windowID OSSDL2Driver>>convertEvent: [ event := self convertEvent: sdlEvent. event ifNotNil: [ eventQueue nextPut: event ] ] in OSSDL2Driver>>processEvent: in Block: [ event := self convertEvent: sdlEvent.... BlockClosure>>on:do: OSSDL2Driver>>processEvent: OSSDL2Driver>>eventLoopProcessWithoutPlugin [ self eventLoopProcessWithoutPlugin ] in OSSDL2Driver>>setupEventLoop in Block: [ self eventLoopProcessWithoutPlugin ] [ self value. Processor terminateActive ] in BlockClosure>>newProcess in Block: [ self value.... But it seems incomplete. Any more information I can provide? Thank you.

Re: [Pharo-dev] RES: Anoying bug fond in Artefact running in Windows 10

by Stephane Ducasse

Hi Casimiro I do not thing that artefact use OSProcess and (OSWindow is for handling even). Can you try using plain FileSystem instead of FileStream because may be this is the problem. 'myfile.jpeg' asFileReference readStream And let us know.

Probably stupid... question about string printString.

by Stephane Ducasse

Hi I would like to really understand why 'foo' printString >>> '''foo''' and not why this is not 'foo' itself. Stef

I think PharoLauncher says 6.1 but then launcehes an image 6.0 or some version info is messed up The image start screen title is "Welcome to Pharo 6.0 but the text says Pharo 6.1 Smalltalk versioin prints as Pharo 6.0 So does SmalltalkImage current I would give the results if print in Playground could be copied but evey time I try to select the output it goes away and you can't select and copy from an inspector either In all GUI text should be select able the only reason it is not is to annoy people I think somewher I got a build daye of May 2017 I was trying to load iceberg as well I think I was trying to creat a bug report but fiorst I need the version number and as that seems buggy I gave up. -- Mark
