Sorry, but this is the only reasonable thing I can rescue from this whole thread. The same discussion arises every year once or twice and is always same result: nothing, except people getting angry and trolling in every possible directionâ¦ we will *never* reach an agreement here because is a subjective matter. Is that a reason to zealot about? No (and take into account Iâm referring to all positions here, not just one side or another). So I will ask *again* too calm down and letâs talk about what is really important? This thread has now 44 mails (45 with this now)â¦ of those, just the first mail had something to do with the original purpose. Stay calm, stay coolâ¦ we are all big persons with strong opinions that deserves respect. But we are here to put that positions aside and to discuss about what we can do togetherâ¦ they can be great of dust, you decide. Esteban ps: if it helps, consider this thread as âmoderated: not constructiveâ :)

Catching Exceptions without any notice
by Nicolai Hess April 3, 2016

April 3, 2016

Please don't do this: updateHeight "no need to care about height, when it's logic is not customized" self layout isHeightCustom ifFalse: [ ^ self ]. [ self bounds: (self brickBounds withHeight: self customHeight) ] on: Exception do: [ "just skip and do nothing" ] This makes debugging GLM/Brick ui/layout code with "self haltOnce" impossible. see GLMBrickGeometryTrait>>#updateHeight GLMBrickGeometryTrait>>#updateWidth And if you log out the raised exception, you see some calls to not initialized fonts and a ZeroDevide and some more errors. The above catch, catches and hides wrong / to late initialized objects.

Project page is at http://www.smalltalkhub.com/#!/~OS/OS-Linux-CentOS Ready for Pharo 5. As ever you can load from Catalog tool or directly by entering "CentOS" into the Spotter search tool.

'Bad argument for external function' with UFFI... no clue
by Mariano Martinez Peck March 31, 2016

March 31, 2016

Hi guys, Could someone help me understand what could be the exact reason of a 'Bad argument for external function' in an FFI call? Of course, I double checked all the arguments definitions in the #ffiCall: and the real objects I receive as arguments at the moment of the callout. And they all seem correct. And even better...how can I get more info about it? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

[ANN] OS-Windows 2.1 project updated for Pharo 5 (NB to UFFI transition)
by Torsten Bergmann March 31, 2016

March 31, 2016

Hi, the "OS-Windows" package [1] from my "OS-xxx" Pharo goodies series [2] is providing better access to native Windows APIs and wraps Windows functionality for easier access/coding in Pharo (browser, console, processes, shell, window, GDI, ...). Some of you may know or use this package already. Up to the last provided stable version for Pharo 4 all my code and bindings were based on "old" NativeBoost (NB). With the transition away from NB over to new UniversalFFI (UFFI) within Pharo 5 it was necessary to port/migrate the code over to UFFI for all the OS-xxx projects. Work of the Windows port started when UFFI was still shaky (December) and in a separate repo [3]. It was not easy in the beginning, some headbanging against the wall and feeling like a crash test dummy was involved - basing the port on early UFFI code and without much documentation. Several UFFI issues had to be discussed with Esteban Lorenzano in private conversations on #slack: often leading to some updated UFFI versions afterwards and an updated worklog of Esteban [4]. In the Pharo spirit "step by step" all of this got analyzed, fixed, renamed, improved and integrated into latest Pharo 5 in the last months. Esteban was VERY VERY supportive and adopted UFFI for all the needs! ONCE AGAIN: A BIG THANK YOU, ESTEBAN!!! Long story short: I can now release "OS-Windows" again into the wild for Pharo 5: fully compatible, again with cleaner code, some more functionality and even more tests (from 77 to now 81) As ever it is easy to access: open spotter in Pharo 5 and load "OSWindows". Full docu is on the project page [1], the new version is fully compatible to the Pharo 4 version so there was no need to change a single line in the tutorial. ;) Have fun T.
