[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. (((Smalltalk at: #ConfigurationOfKeymapping) perform: #project) perform: #version: with: '1.2') load: #( 'default' 'tests' 'configurations' ) * To look the example look at KeymapDefaultConfiguration class>>declareDefaultKeymapsOn: Cheers, Guille :D

Hello, i almost done with generating an app bundle for Cog VM , and i found that it is using a Croquet Icon. Which doesn't seems right to me. I remember there was a guy , who presented a nice cog icon and other graphics.. anyone knows where i can find them? -- Best regards, Igor Stasenko AKA sig.

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?

[Pharo-project] New features ...
by James Ladd Dec. 23, 2010

Dec. 23, 2010

Hi All, >From what I understand of Smalltalk new language constructs can be added as long as they fit in with the "message passing" scheme/principle. Since the release of Smalltalk-80 I think some new constructs have been added and I need an example for a piece I am writing. Can someone tell me what syntactical construct was added since Blue Book - Smalltalk-80 ? I think "on:do:" was, but Im not sure. Rgs, James.

[Pharo-project] Mars, stuck on callbacks (again)... need opinions
by Esteban Lorenzano Dec. 23, 2010

Dec. 23, 2010

Hi guys, I'm doing some "advance callbacks" for Mars, and I'm having several problems with table renderers (they are called A LOT of times and needs to be efficient). The ObjectiveCBridge is not as efficient as that calls needs to be executed, and well... I was planing to spend some time on this, trying to see how can I improve the callback velocity. And then a question came to my mind: do I spend time improving current ObjectiveCBridge implementation... or I better use Alien and migrate everything to it? some context: 1) it was always planned to "sonner or latter" migrate the ObjectiveCBridge stuff to alien (there is another . 2) Alien is not working -yet- for iPhone. It is planned (bah... it is "thought") to run Alien in iPhoneVM too. 3) Alien callback implementation is a lot cleaner than the current ObjectiveCBridge implementation (which relies on both sides semaphores, when alien callbacks relies on "image ownership") So... it will delay a little a release of Mars? sure it will... but in the long way it will be better. I would like to hear your opinions, cheers, Esteban
