Best method for connecting to an Oracle 11g database
by Aaron Blakeman April 20, 2018

April 20, 2018

Hello, I'm trying to use Pharo 6 to connect to an Oracle 11g database. I tried using dbxtalk with the opendbx driver, but I can't seem to get that to load cleanly into a Pharo 6 image. Before I spend alot of time trying to debug DBXtalk I wanted to see if anyone else had any recommendations. Is there currently any better method for connecting from Pharo 6 to an Oracle database? Thanks!

[Pharo-Launcher] call for tests on Windows
by Christophe Demarey April 19, 2018

April 19, 2018

Hi, Regarding the various problems Pharo Launchers had on Windows, we worked on a new installer based on Advanced Installer [1] to avoid UAC (User Account Control) and write permissions problems. This new installer now installs Pharo Launcher in the userâs local app data folder (where for sure, he has write permissions). Pharo Launcher also now have its own icon and use its own name instead of Pharo. Also, the uninstaller now works as expected. Last but not least, the installer is now signed to avoid warning of Windows Defender. Thanks to Ben Coman who did the first version of the packaging using Advanced Installer (was NSIS). This version should also improve the launch of Pharo images on Windows. So, please could you install and test this new version: and report any problem with it? http://files.pharo.org/pharo-launcher/win-alpha/ We do not have windows users around so itâs hard to know if it works outside our tests boxes. Thanks, Christophe [1] https://www.advancedinstaller.com/

SDL2SpecialCharacterMapping problem
by alvaro piorno April 19, 2018

April 19, 2018

Hi, Iam having a problem handling some OSKeywordEvents. These events should have character associated. The mapping is resolved by SDL2SpecialCharacterMapping using a dictionary(Mappings), it has the mapping, for example, for left arrow and right arrow. It resolve correctly for "left arrow" with key: 1073741904(Integer) , but it does not found "right arrow" with key: 1073741903(Integer). Both keys are present. Any idea?

C struct in 32 bits vs 64 bits VM
by Serge Stinckwich April 19, 2018

April 19, 2018

I try to understand differences between 32 bits and 64 bits FFI support for C structures. I build a class called MyStruct subclass of FFIExternalStructure. and define a layout for this structure like this one : MyStruct class>>fieldsDesc "self rebuildFieldAccessors" ^ #( int index ;) and then I generate automatically the field accessors. If I use a 32 bit VM, the following method is generated to access the index field : index "This method was automatically generated" ^handle signedLongAt: OFFSET_INDEX and if I use a 64 bits VM, the same method is generated ... I'm a bit puzzled because, if sizeof(int) = sizeof(long) in a 32 bits VM, they have different for 64 bits VM (sizeof(int) = 4 and sizeof(long) = 8). Someone to explain me or this is a bug ? âThank you.â -- Serge Stinckwich UMI UMMISCO 209 (SU/IRD/UY1) "Programs must be written for people to read, and only incidentally for machines to execute."http://www.doesnotunderstand.org/

It bombs. I just reported a bug! > > Can I expect the Windows installer for Pharo Launcher to work on Windows? > It doesn't : it crashes. > It works fine for me on Windows 10. There were some issues that depended on how PharoLauncher was installed. The installer (NSIS) being used at that time doesn't handle non-Admin installs very well. Prior to PharoLauncher being promoted as the main download, I guess people on Windows using PharoLauncher either ran it as Admin, or worked around it like me - on Windows I would just roll my own from a fresh Pharo 6 and the Project Catalog. To be clear, the problem was heavily influenced by the constraints of an external tool. Get PharoLauncher installed in the right location and it works like a dream. Did you try the proof-of-concept installer I posted previously to the list... http://www.mediafire.com/file/3g579bmzqspt8e1/BCPharoLauncher.msi > > Can I expect Pharo Launcher (not installed from the .exe installer) to > work on Windows?

I get duplicates (see attached file). > Do you mean only the duplicate "Traited class >> isTrait" in your screenshot? I just tried this in "Pharo-7.0+alpha.build.762.sha.0e0fe47c5ccef" by typing "isTrait" into the Playground, selecting it and pressing Ctrl-M, and I don't get the duplicate.

Regarding 64-bit Windows. Yes it is behind. The specific companies interested in 64-bit Linux support put money on the table to get it done. No one has stepped up to do the same for Windows 64-bit, so realistically it lags behind. btw, lately it gets harder to run 32-bit apps on Linux and OSX, but there is no reason to stop using 32-bits VM on Windows. > > Can I expect to be able to contribute ?

Hi, SmalltalkCI now supports loading tonel-based projects, so feel free to start using it. The configuration is still the same. Please note that coveralls support for tonel is not yet in place, but that's just a cherry on top. :-) Cheers, Peter

Playground and Smalltalk script
by Hilaire April 18, 2018

April 18, 2018

Hi, Same question asked there http://forum.world.st/Pharo-4-Playground-open-file-menu-tt4823334.html. I tried to follow the suggested solutions: 1) Following article: http://www.humane-assessment.com/blog/managing-external-pharo-scripts-with-… Accessing to DrGeo SmalltalkScripts folder from Spotter, it works when the user input ../../SmalltalkScripts. As it is not a discoverable features for the user, I want to add a menu entry in the world menu to open Spotter with path ../../SmalltalkScripts already set. I tried: Â GTSpotterMorph new Â Â Â Â Â Â extent: 400@500; Â Â Â Â Â Â doLayout; Â Â Â Â Â Â spotterModel: (GTSpotter on:DrGDefault mySketchesPath parent / 'SmalltalkSketches' ); Â Â Â Â Â Â openCenteredInWorld (Btw, the descriptions in the Settings browser concerning Spotter are still broken.) When dive-in the display script is empty, any idea? I have to Enter to get it seens in an inspector. Moreoever I see one minor issue: Spotter looks at relative path relatively from the folder where the image was built not from where it is runned. Note: FileBrowser properly open relatively to the path where it is runned. 2) I tried the complementary approach with play-cache, I edited in the setting browser the play cache path to DrGeo SmalltalkScripts. Now when I edit some new scripts in the Playground, I can rename it and it is saved in the SmalltalkScripts. Now when exploring, the SmalltalkScripts, there are several additionnal file not meaning full for the enduser. Is there a way for Playground to only save one file as pageName.st? An interesting option will be for me to add two menu entries in GTPlayground to load/save script. Is it possible? It will make the user experience a bit easier. Thanks Hilaire -- Dr. Geo http://drgeo.eu
