Hi everyone,
sorry, if I’m annoying with this question, but is there a way to handle
keyboard events (on mac) in a normal way? Because keyUp and keyDown do not
have any information about the key itself. I know that it’s a long story
also related with vm but maybe someone made some hacks to solve this
problem?
Cheers
Uko
The logic is in sqSqueakOSXApplication+events.m
Now, I do not have the latest version but it is true that keyUp and keyDown
are not handled very nicely there.
KeyDown doesn't seem to have any code (but one could set something there as
the code is available). KeyUp has something.
I do not know why things are done this way. There may be side effects in
the VM if one changes the way things are...
Good luck.

Re: [Pharo-dev] Stepping through with GLORP Proxies
Hi Stef, 2014-06-24 3:18 GMT-03:00 stepharo steph...@free.fr: Esteban I would like to know how different are the Glorp proxies from the ones of Mariano. Because we are thinking about to get by default a nice proxy system. Proxies in the sense of object representing one that is not in the system (and not proxies as metaobject or representing an object that is around as in the JS literature). Ideally I would like to unify both. There's nothing much special about GLORP proxies, and maybe Mariano knows better. They have a common superclass named AbstractProxy (no NS), and they work more like remote references than anything else. They are true proxies, it is, they hold a reference to the realobject, but no #become is involved in the process. Also proxies can release the referenced object and materialize it back when needed (according to the proxy strategy). Proxy#class returns Proxy, but Proxy#isKindOf: aClass returns whether the referenced class is aClass (it is, aProxy isKindOf: Proxy false), #= and #hash causes materialization of the referenced object.

Maringolo emaring...@gmail.com wrote: Hi Stef, 2014-06-24 3:18 GMT-03:00 stepharo steph...@free.fr: Esteban I would like to know how different are the Glorp proxies from the ones of Mariano. Because we are thinking about to get by default a nice proxy system. Proxies in the sense of object representing one that is not in the system (and not proxies as metaobject or representing an object that is around as in the JS literature). Ideally I would like to unify both. There's nothing much special about GLORP proxies, and maybe Mariano knows better. They have a common superclass named AbstractProxy (no NS), and they work more like remote references than anything else. They are true proxies, it is, they hold a reference to the realobject, but no #become is involved in the process. Also proxies can release the referenced object and materialize it back when needed (according to the proxy strategy). Proxy#class returns Proxy, but Proxy#isKindOf: aClass returns whether the referenced class is aClass (it is, aProxy isKindOf: Proxy false), #= and #hash causes materialization of the referenced object. Other than that I couldn't find anything else, it's a classical proxy, with some ORM related stuff. yeah, that’s why I said is not a problem of GLORP proxies but about our treatment of proxies in general :) Esteban Regards!
Re: [Pharo-dev] SystemWindow instances can't be garbage-collected
For documentation purposes, this is what I found to be necessary to really clean all window instances. Note that this only works reliably when invoked from a non-UI process (e.g. via WAKom). cleanupWindows in general: the gabage collector seems to be unable to resolve all circular dependencies with weak pointers. This forces us to explicitly remove the weak pointers to enable garbage colltection. It also seems to be a problem to invoke the cleanup from within a UI process (e.g. from a workspace). Ergo: - when invoked from a workspace not all instances may be garbage collected - when invoked from a non UI process (e.g. WAKom) all instances should have been collected - performning a manual garbage collection after having invoked this code from a workspace will (usually) remove the pending instances (new process context) | count | count := 1. self cleanupEvents; cleanupWorkspaces; cleanupSystemWindows.

Re: [Pharo-dev] Spec Button Shortcut Indication
2014-06-23 22:53 GMT+02:00 Sven Van Caekenberghe s...@stfx.eu: Hi, The following looks different in my Dark Theme image vs a Standard image (same version #30848): ButtonModel new label: 'Click Me'; shortcut: $C asShortcut; action: [ self inform: 'OK, you clicked me !' ]; openWithSpec. The difference is the C that is underlined. Is this intentional ? Is there a way to have a shortcut, but not the underlining ? Thx, Sven I don't see any difference in 30848 and 40038. Both show underlined char. (even with the dark theme). It is intentional, and new (this year). I don't think it is possible to suppress the underlining.
Re: [Pharo-dev] Cloudfork HMAC-SHA256 in System-Hashing
thank you, Sven. Did you try this in 3.0, too. I would need it there!

I'm no expert in those stuff but I don't get SHA256 base implementation. Someone with more knowledge can probably tell ;) Sven, The bare minimum to load it is: Gofer it smalltalkhubUser: 'JanVanDeSandt' project: 'Cloudfork'; package: 'Cloudfork-Common'; package: 'Cloudfork-Pharo-Platform'; load. The implementation is in Cloudfork-Pharo-Platform. On Thu, Jun 19, 2014 at 6:20 PM, Sven Van Caekenberghe s...@stfx.eu wrote: I want to have a look, if you tell me where to look...

Can Cloudfork HMAC-SHA256 be easily parameterized with, say, an SHA256 base implementation? Or does it require extra stuff? In the former case I probably wouldn’t add it. In the latter case it’s open for discussion. Personally, I think it belongs into a separate package, not into System-Hashing. Cheers, Max

Your proposal: classVariableNames: 'MaxLengthForASingleDebugLogReport MaxStackDepthForASingleDebugLogReport PrimitiveFailToken QuickStep ValueIndex' Current vars: classVariableNames: 'PrimitiveFailToken QuickStep SpecialPrimitiveSimulators TryNamedPrimitiveTemplateMethod' Obviously my change set was for Squeak, and the def above is for Pharo. So the two definitions need to be merged. Did you try the union of the class variable names? Would you mind adapting your mirror methods changes to work also in Pharo 3 (and maybe in Pharo 4 too?).
