[Pharo-project] CustomMenu was replaced by MenuMorph?
by Guillermo Polito Dec. 26, 2010

Dec. 26, 2010

I was looking at Release>>testUndeclared that is failing in 1.2 dev. And of course it is failing because there are some methods pointing to some undeclared variables/globals/classes :). I found some references to CustomMenu and I'm not sure how to replace them :).

[Pharo-project] accessors vs direct access in Cog
by StÃ©phane Ducasse Dec. 26, 2010

Dec. 26, 2010

Hi guys Ideally I would love to be able to use accessors as the abstraction layer that they can bring us: I mean the fact that we could avoid to have offset based bytecode means that we could reuse a lot more the methods (in special case - mixins and others). Now I have a question does the JIT or the shortcut (not sure if this is in stackVM) blurry the cost of accessors vs. direct accesses? Does anybody run a benchmarck about self x vs x in Cog recently on a real app? Stef

[Pharo-project] [ANN] [Chrismas gift(?)] New version of Keymapping
by Guillermo Polito Dec. 25, 2010

Dec. 25, 2010

Last version of keymapping supports: - Keymap definition by pragmas - Shortcut dsl that looks like KMMeta + $r, $b (which means Alt + r, b) KMCmd + $r, KMCmd + $d (which means Cmd + r, Cmd + d) *+ is to combine modifiers to characters* *, is to define sequence of shortcuts* KMMeta is meta (Alt I suppose) KMCmd is Cmd (Ctrl I guess) KMShift is Shift - The morphs inherits their superclasses shortcuts. - ALOT of cleansing, renaming, refactoring To come: - more documentation :P - more refactoring and cleansing :P. - Application specific shortcuts (To attach shortcuts to morph's models) To download: *Gofer it squeaksource: 'Keymapping'; package:'ConfigurationOfKeymapping'; load.

Re: [Pharo-project] Z3950 on OSX: module yaz3 not found
by laurent laffont Dec. 24, 2010

Dec. 24, 2010

Hi Hernan, finally I switch back to Linux to make it work, OSX gives me headaches. So on linux the yaz module is found. I get the "Unable to find function address" but I found that writing: <cdecl: ZOOMOptions 'ZOOM_options_create' (void) module: 'yaz'> instead of <cdecl: ZOOMOptions '_ZOOM_options_create@0' (void) module: 'yaz3'> works. If I understand, function names are not mangled when compiling with gcc on Linux. Trying to run tests I've also had a "could not coerce arguments" in Z3950FFILibrary>>createConnectionTo:port because Z3950TestCase>>portNumber answers a String and <cdecl: ZOOMConnection 'ZOOM_connection_new' (char* short) module: 'yaz'> so it's waiting for a short. I've replaced portNumber to answer a SmallInteger. And now the image crashes on connectionIsIdle call: write(1, "\ncreateConnectionTo:port:", 25) = 25 write(1, "\nconnectionIsIdle:", 18) = 18 rt_sigprocmask(SIG_UNBLOCK, [ABRT], NULL, 8) = 0 write(1, "\n", 1) = 1 tgkill(25830, 25830, SIGABRT) = 0 --- SIGABRT (Aborted) @ 0 (0) --- Any idea ?

[Pharo-project] SandstoneDb + SortedCollections
by David Zmick Dec. 24, 2010

Dec. 24, 2010

I am trying to use SandstoneDb to save an Object that contains a SortedCollection, but it fails with the error: "This message is not appropriate for this object". Here is an example code. SDActiveRecord subclass: #User instanceVariableNames: 'sorted name' classVariableNames: '' poolDictionaries: '' category: 'Sandbox' User>>initialize super initialize. sorted := SortedCollection new. name := 'asd' and of course accessors for both of my variables. I type this into a workspace: (User new name: 'david') save. User find: [:u | u name = 'david'] And it works correctly, but this errors with: "This message is not appropriate for this object" | u | u := User new. u name: 'david'. u sorted add: 1. u save What can I do to fix this?
