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.
