It will be a good step forward in having better window management. Now we should rewrite this clean + tests (may be adding the notion of widgets like in KDE / Gnome). As windows fill all the space, would be good to have a button to open the world menu. I would love having the possibility of splitting the World + back and forward configuration like Emacs winner mode, keyboard driven.

That is why I asked if someone knows how should the method behave. In older images (1.2), there is an #actOnClickFor: on the TextAction Hierarchy. TextDoit does for example: actOnClickFor: anObject "Note: evalString gets evaluated IN THE CONTEXT OF anObject -- meaning that self and all instVars are accessible" Compiler evaluate: evalString for: anObject logged: false. ^ true It seems the interface was extended to send the editor instance and the paragraph to the Link, so that a link could e.g. change what is displayed. What kind of TextAction do you have? You could just implement there whatever action makes sense (ignoring the editor and paragraph parameter and do exactly what #actOnClickFor: did in the old ST80 Paragraph). The whole TextAction stuff needs a pass... maybe with Moose as a Client, we can do that pass... Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

[Pharo-project] Questions of understanding

by Friedrich Dominicus

Dear Pharoisten, I have a couple of questions about my understanding about Pharo, the VM and COG. the COG VM is the "normal virtual machine as I understand" At least my Pharo give me: 'Croquet Closure Cog VM [CoInterpreter VMMaker-oscog.35]' It is my understanding that the Cog sources do not contain the actual SerialPlugin stuff from SergeStinckwicj- At least I can not find anything like OpenPortByname or writeToNamed port or the like. So I fetched the Squeak sources and the Cog sources and indeed they are different. The Cog version defines: #ifdef SQUEAK_BUILTIN_PLUGIN void* SerialPlugin_exports[][3] = { {"SerialPlugin", "getModuleName", (void*)getModuleName}, {"SerialPlugin", "initialiseModule", (void*)initialiseModule}, {"SerialPlugin", "primitiveSerialPortClose", (void*)primitiveSerialPortClose}, {"SerialPlugin", "primitiveSerialPortOpen", (void*)primitiveSerialPortOpen}, {"SerialPlugin", "primitiveSerialPortRead", (void*)primitiveSerialPortRead}, {"SerialPlugin", "primitiveSerialPortWrite", (void*)primitiveSerialPortWrite}, {"SerialPlugin", "setInterpreter", (void*)setInterpreter}, {"SerialPlugin", "shutdownModule", (void*)shutdownModule}, {NULL, NULL, NULL} }; #endif /* ifdef SQ_BUILTIN_PLUGIN */ Whereas the Squeal-vm version contains e.g: #ifdef SQUEAK_BUILTIN_PLUGIN void* SerialPlugin_exports[][3] = { {"SerialPlugin", "primitiveSerialPortWrite", (void*)primitiveSerialPortWrite}, {"SerialPlugin", "primitiveSerialPortClose", (void*)primitiveSerialPortClose}, {"SerialPlugin", "primitiveSerialPortOpenByName", (void*)primitiveSerialPortOpenByName}, {"SerialPlugin", "primitiveSerialPortWriteByName", (void*)primitiveSerialPortWriteByName}, {"SerialPlugin", "primitiveSerialPortReadByName", (void*)primitiveSerialPortReadByName}, {"SerialPlugin", "shutdownModule", (void*)shutdownModule}, {"SerialPlugin", "primitiveSerialPortOpen", (void*)primitiveSerialPortOpen}, {"SerialPlugin", "initialiseModule", (void*)initialiseModule}, {"SerialPlugin", "setInterpreter", (void*)setInterpreter}, {"SerialPlugin", "getModuleName", (void*)getModuleName}, {"SerialPlugin", "primitiveSerialPortCloseByName", (void*)primitiveSerialPortCloseByName}, {"SerialPlugin", "primitiveSerialPortRead", (void*)primitiveSerialPortRead}, {NULL, NULL, NULL} }; #endif So now it seems the Cog version is for building an internal plugin. (I may be mistaken of course) but the code for primitiveSerialPortOpen looks like this: EXPORT(sqInt) primitiveSerialPortOpen(void) { sqInt baudRate; sqInt dataBits; sqInt inFlowControl; sqInt outFlowControl; sqInt parityType; sqInt portNum; sqInt stopBitsType; sqInt xOffChar; sqInt xOnChar; portNum = interpreterProxy->stackIntegerValue(8); baudRate = interpreterProxy->stackIntegerValue(7); stopBitsType = interpreterProxy->stackIntegerValue(6); parityType = interpreterProxy->stackIntegerValue(5); dataBits = interpreterProxy->stackIntegerValue(4); inFlowControl = interpreterProxy->stackIntegerValue(3); outFlowControl = interpreterProxy->stackIntegerValue(2); xOnChar = interpreterProxy->stackIntegerValue(1); xOffChar = interpreterProxy->stackIntegerValue(0); if (interpreterProxy->failed()) { whereas the Squeak sources looks like this: int serialPortOpen(int portNum, int dataRate, int stopBitsType, int parityType, int dataBits, int inFlowCtrl, int outFlowCtrl, int xOnChar, int xOffChar) { char serialPortName[PORT_NAME_SIZE]; make_portname_from_portnum(serialPortName, portNum); return serialPortOpenByName(serialPortName, dataRate, stopBitsType, parityType, dataBits, inFlowCtrl, outFlowCtrl, xOnChar, xOffChar); } So I assume one has to make the changes as in the cog examples to make this plugin workable in Cog. Is that a correct impression. Well then it comes to the questions of how to properly write a plugin for the COG vm. Are there any tutorials about it, or is the best I can hope for the sources for Cog itself? My understanding is that stackIntegerValue, picks out a parameter from a Cogs primitive. Is that a correct impression? It seems that at least the following things have to be exported from a plugin: getModuleName setInterpreter and maybe initializeModule shutdownModule The latter are probably for cleaning up.... But maybe I'm on the complete wrong track. Because at the beginning I can read: /* Automatically generated by SmartSyntaxPluginCodeGenerator VMMaker-oscog.40 uuid: 637db40c-33c6-4263-816e-1b8cc19e3c99 from SerialPlugin VMMaker-oscog.40 uuid: 637db40c-33c6-4263-816e-1b8cc19e3c99 */ So is this code not written in C but maybe somewhere else? As you can see I'm more than less clueless. So what is the "supposed" way to migrat that kind of code?

Other think is the internal ScaledDecimal represent. It's important to rounding the data so that the numerator and denominator are integer. I do it wtih method : roundToPrecision: scalePrecision | rnd | rnd:= ScaledDecimal new setNumerator: 1 denominator: (10 raisedTo: scalePrecision) scale: scalePrecision. ^self roundTo: rnd The round is automatic when i create ScaledDecimal instance with: fromString: aString For example when converter a input string to ScaledDecimal instance based on number of digit typed. It's required when i do conversion from another Number type: ( 1/3 asScaledDecimal: 3 ) roundToPrecision It's all for now. Any pointers would be greatly appreciated ! Thanks, Dario
