[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] Issue 1064 in pharo: There are still problem with keyboard shortcuts in Windows

Comment #12 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; } 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 should be processed. Please see msdn about TranslateMessage. An attached file is source, which has been corrected by above way. see also Comment 11. Thanks, Attachments: sqWin32Window.c 99 KB

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!

you click on open the repository select the package version press history use the menu select the version you want spawn select the latest something like that.

Later people understood that MIT is even better... Wikepedia says: The MIT License is similar to the 3-clause "modified" BSD license, except that the BSD license contains a notice prohibiting the use of the name of the copyright holder in promotion. This is sometimes present in versions of the MIT License, as noted above. The original BSD license also includes a clause requiring all advertising of the software to display a notice crediting its authors. This "advertising clause" (since disavowed by UC Berkeley[7]) is present in the modified MIT License used by XFree86. The MIT License states more explicitly the rights given to the end-user, including the right to use, copy, modify, merge, publish, distribute, sublicense, and/or sell the software. For the Undo it was nor really worth to think about what it means to add BSD (and which of the BSD?) licensed code to an MIT licensed system...

Using the tracer makes things like changing the bytecode set or replacing characters with immediate characters more difficult. There's also value in having a declarative definition of the core system. Yes. now our problem is not really to have a source code bootstrap for a smalltalk. Gwenael did that in 3 days for his smalltalk but he was controlling all the details (all his object have named and variable size) and only one kind. With Pharo we are reverse engineering format and other hardcoded knowledge with bitAnd: and bitshift: when it would have been so much simpler to have better names. So we will go there but first we should extract the knowledge from the mud.

Re: [Pharo-project] Coral?

by StÃ©phane Ducasse

> What is coral all about? There seems to be no documentation except a little tutorial. But the tutorial does not make much sense to me. It explains the installation of coral and the result is that you can run a script from the commandline. Well, that is possible anyway. So where is coral located. Between positioning it as a shell replacement in the mailing list and the "just runs a shell script" is a huge space where it could be actually located. Any hints are appreciated. We want a scripting syntax to be able to builds script with pharo so we have coral. In coral you write Point >> mydistance [ ^ x * x ] Point class>>myNewPointWithx: anInt withY: another [ ] With OSProcess we access os behavior and yes I should fix the configurationOf...
