Re: [Pharo-project] Coral?

by Ricardo Moran

I haven't really tried Coral yet, so please forgive my ignorance, but have you thought of using a modified block syntax to define methods? I'm thinking of something like this: [factorial | "Answer the factorial of the receiver." self = 0 ifTrue: [^ 1]. self > 0 ifTrue: [^ self * (self - 1) factorial]. self error: 'Not valid for negative integers' ] [min: aMin max: aMax | ^ (self min: aMin) max: aMax ] [+ aNumber | "Refer to the comment in Number + " aNumber isInteger ifTrue: [self negative == aNumber negative ifTrue: [^ (self digitAdd: aNumber) normalize] ifFalse: [^ self digitSubtract: aNumber]]. ^ aNumber adaptToInteger: self andSend: #+ ] Evaluating one of these expressions could return a compiled method without a class. And since we use the ">>" to retrieve a method, we could use the "<<" operator to add it to a class's method dict. I think it would make a very simple and consistent syntax. And maybe we could even modify the entire system to support it. I wouldn't mind seeing a couple of extra brackets and a vertical bar in the browser if the method's syntax is made more consistent. Anyway, it's just an idea... Best regards, Richo On Sat, Mar 5, 2011 at 3:58 PM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr>wrote: > > > What is coral all about?

[Pharo-project] Pharo 1.2 and test failures

by Norbert Hartl

Today I had a look at the hudson server. For pharo 1.2 dev there was only one bug left. So I took a look and fixed it http://code.google.com/p/pharo/issues/detail?id=3784 Two hours later there was a new build in hudson and then there were three bugs (one of these is the fixed one which hasn't been integrated). How can this happen? Norbert

Re: [Pharo-project] Issue 1064 in pharo: There are still problem with keyboard shortcuts in Windows

by pharo＠googlecode.com

Comment #14 on issue 1064 by happy.lo...(a)gmail.com: There are still problem with keyboard shortcuts in Windows http://code.google.com/p/pharo/issues/detail?id=1064 Hi, I'm tn. 'ctrl + m' problem is Cog VM bug. Normally, when character key is pushed, keyboard events occur as follows on Squeak. 1. key press (down) 2. character (character code notification) 3. key release (up) They are produced by a primitive method in IutEventFetcher >> primGetNextEvent. But when ctrl + m is pushed, a character event doesn't occur. Because 'ctrl + m' value is 13. The value is same as ENTER key. Cog VM ignores WM_CHAR message(character event) when ENTER key is pushed. The one of solution for this problem is to add CTRL key state to the if-condition. -- sqWin32Window.c -- int recordKeyboardEvent(MSG *msg) { ... switch(msg->message) { ... case WM_CHAR: case WM_SYSCHAR: /* Note: VK_RETURN is recorded as virtual key ONLY */ if(keyCode == 13 && !ctrl) return 1; // add "&& !ctrl" pressCode = EventKeyChar; break; ... } ... Note: ENTER keyCode is 13. But when ctrl + ENTER is pushed, the keyCode is 10. So if the condition is revised, ctrl + m problem is corrected. but other behavior is not changed. If you want to prevent to generate character event for CTRL + ENTER, you can add following code. By this way, we can produce not only ctrl+m (0x0D)'s character event but also ctrl+j (0x0A)'s one. -- sqWin32Window.c -- // add this function static int isNotKeyDownCtrlReturn(MSG* msgp){ if(msgp->message == WM_KEYDOWN && msgp->wParam == VK_RETURN){ if(GetKeyState(VK_CONTROL) & 0x8000) { return FALSE; } } return TRUE; } ... int ioProcessEvents(void) { static MSG msg; ... if(isNotKeyDownCtrlReturn(&msg)){ // add TranslateMessage(&msg); } // add DispatchMessage(&msg); ... } ... int recordKeyboardEvent(MSG *msg) { ... if(pressCode == EventKeyDown && virtCode != 0 && isNotKeyDownCtrlReturn(lastMessage) ) { // add " && isNotKeyDownCtrlReturn(lastMessage) " /* generate extra character event */ ... } return 1; } An attached file is source, which has been corrected by above way. Note: Below is a comment in the source code. /* note: several keys are not reported as character events; most noticably the mapped virtual keys. For those we generate extra character events here */ Those keys(e.g. arrow) should not be ascii code. ENTER key is not. but an extra character events is created for ENTER. I don't think this behavior is correct. As for ENTER key, an extra character event must not be generated, and WM_CHAR message should be processed.

[Pharo-project] Issue 3785 in pharo: WeakOrderedCollection from Squeak required for Magma on Pharo 1.2 and 1.3

by pharo＠googlecode.com

Status: Accepted Owner: miguel.c...(a)gmail.com Labels: Milestone-1.3 New issue 3785 by miguel.c...(a)gmail.com: WeakOrderedCollection from Squeak required for Magma on Pharo 1.2 and 1.3 http://code.google.com/p/pharo/issues/detail?id=3785 This is a extraction of the changes of Collections-cmm.404.mcz Collections-cmm.404.mcz from http://source.squeak.org/trunk/ that add WeakOrderedCollection to the system. Modifies OrderedCollection in order to have a uniform way to create ordered collections (weak and normal). For Pharo 1.2 that is in freeze right now, it will be managed as a dependency in the ConfigurationOfMagma on a mcz with the said changes in PharoTaskForces (or maybe included in PharoCore 1.2.1?) For Pharo 1.3 the changes should be integrated in Pharo Core, for compatibility with Squeak.

Re: [Pharo-project] Monticello diff between 2 version

by Miguel CobÃ¡

Oh yes, that worked, but nothing intuitive. And the menu only appears in the history windows for the second entry and all below, but if you select the first it doesnt do anything. A simple button "Compare selected versions" enabled after selecting any two versions would be just enough. Anyway, thanks it worked!
