Talents - VM Crash on P9 after Fuel Materialization
by sean＠clipperadams.com Feb. 26, 2022

Feb. 26, 2022

After serializing and then materializing an object with a talent, the trait's instVar seems to have disappeared from the inspector, although the print string looks like that of a Talented object. If you send a getter for a talented ivar, Pharo crashes. Not sure if this is a Talents problem or a Fuel problem (or both). More details and reproducible steps here: [https://github.com/tesonep/pharo-talents/issues/11]( https://github.com/tesonep/pharo-talents/issues/11 " https://github.com/tesonep/pharo-talents/issues/11") Anyone have some insight?\ \ I reported on Jan 7, but maybe more eyeballs here. Iâve been eager to give Talents a real try, but use Fuel extensively, so this is a blocking issue for me.

PTerm - Can't Find FFI Library on M1 Mac on P9
by sean＠clipperadams.com Feb. 26, 2022

Feb. 26, 2022

The really cool PTerm in-image terminal emulator works for me in P8 but not on P9. I recently upgraded to an M1 Mac, so Iâm trying to isolate whether ARM is the cause of the problem. Can someone try to reproduce the issue described here: [https://github.com/lxsang/PTerm/issues/20](https://github.com/lxsang/PTerm/… "https://github.com/lxsang/PTerm/issues/20") TIA, s

Problem with Pharo 10 in GitHub Action CI using SmalltalkCI
by Sven Van Caekenberghe Feb. 22, 2022

Feb. 22, 2022

Hi, I just tried to enable Pharo64-10 (not Pharo64-10.0 but that is probably another issue) in a GitHub Action CI using SmalltalkCI. https://github.com/svenvc/ston/blob/master/.github/workflows/CI.yml https://github.com/svenvc/ston/runs/5286121566?check_suite_focus=true This fails with NotFound: [ :cl | cl isPlatformCompatible ] not found in OrderedCollection OrderedCollection(Collection)>>errorNotFound: [self errorNotFound: aBlock] in OrderedCollection(Collection)>>detect: in Block: [self errorNotFound: aBlock] OrderedCollection(Collection)>>detect:ifFound:ifNone: OrderedCollection(Collection)>>detect:ifNone: OrderedCollection(Collection)>>detect: SmalltalkCI class>>platformClass ... Does anyone have any idea ? I seem to remember there were some issue with Metacello attributes, but maybe that is not related. Sven PS: I could try with other repositories but that will probably give the same result. Only Zinc does run with Pharo 10, last build a day ago. I can't spot the difference.

Hi, We are seeing lots of issue that are still open, but already fixed or just not valid anymore. e.g. - the fix that was merged but the issue was not closed (sometimes GitHub has problems doing that) - Bug was fixed independent of the issue - The issue is just not relevant anymore It is often quite time consuming to even find out that an issue is already fixedâ¦ It would be nice if everyone could check the issues that - you submitted yourself - that are assigned to you - [Bonus] where you were part of some discussion https://github.com/pharo-project/pharo/issues Marcus

FFI help with *** pointers to get font family list
by Stewart MacLean Jan. 31, 2022

Jan. 31, 2022

Hi, I'm trying to figure out how to implement code to retrieve a list of font families using the Pango libraries. The key function definition is: https://docs.gtk.org/Pango/method.FontMap.list_families.html void pango_font_map_list_families ( PangoFontMap* fontmap, PangoFontFamily*** families, int* n_families ) I've found some C code, which is shown below. The tricky bit is the ***. I've managed to get this working in VisualWorks (code also below), but can't figure out how to do this using the Pharo FFI. I've managed to get the basic Pango functionality going, but I can't figure out how to use ExternalAddress to do this. Running on a MacMini M1. Any pointers (:)) appreciated! Thanks, Stew C Version ---------------- #include <glib.h> #include <pango/pangocairo.h> static void list_fonts () { int i; PangoFontFamily ** families; int n_families; PangoFontMap * fontmap; fontmap = pango_cairo_font_map_get_default(); pango_font_map_list_families (fontmap, & families, & n_families); printf ("There are %d families\n", n_families); for (i = 0; i < n_families; i++) { PangoFontFamily * family = families[i]; const char * family_name; family_name = pango_font_family_get_name (family); printf ("Family %d: %s\n", i, family_name); } g_free (families); } int main (int argc, char ** argv) { list_fonts (); return 0; } ================================= VisualWorks Version --------------------------- availableFamilyNames " Transcript clear.
