The Second Coming of Java article

http://www.wired.com/wiredenterprise/2013/09/the-second-coming-of-java/ The article talks about Java Virtual Machine running dynamic languages like Scala and Clojure in addition to Java. What prevents the Smalltalk Virtual Machine from running Java, Scala, Clojure and other JVM languages? Is that something we can ride on to greater awareness and usage of Smalltalk Virtual Machine and Smalltalk? All the best, Aik-Siong Koh -- View this message in context: http://forum.world.st/The-Second-Coming-of-Java-article-tp4724932.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Simulator & Pharo [was: Second coming of Java...]
by phil＠highoctane.be Nov. 27, 2013

Nov. 27, 2013

Hello, I gave it a shot based on the generator.image that PharoVM uses to generate the VM. But none of : (| vm | vm := StackInterpreterSimulator newWithOptions: #(). vm openOn: '/Users/eliot/Cog/startreader.image'. vm openAsMorph; run) and (| vm | vm := CogVMSimulator newWithOptions: #(ObjectMemory Spur32BitCoMemoryManager Cogit StackToRegisterMappingCogit). vm desiredNumStackPages: 8. vm objectMemory setCheckForLeaks: 1. vm openOn: '/Users/eliot/Cog/spurreader.image'. vm openAsMorph; toggleTranscript; halt; run) is going to work right away as newWithOptions: isn't there in that image. So, there is a initializeWithOptions: #(). When trying out that one, I do get another error. In fact, the initializeWithOptions: method is wrong: initializeWithOptions: optionsDictionary "ObjectMemory initializeWithOptions: Dictionary new" self initBytesPerWord: (optionsDictionary at: #BytesPerWord ifAbsent: [4]). ... the thing is doing #BytesPerWork ifAbsent: ... :-( Of course, as #() is an Array an not a Dictionary. So, I tried: StackInterpreterSimulator initializeWithOptions: Dictionary new. vm := StackInterpreterSimulator new. Which got the ball rolling. But then, of course, same story as here: http://forum.world.st/Got-quot-Error-basicNew-failed-quot-when-running-Inte… Well, based on Clement's comments, I fiddled a bit with the TranscriptStream, which I turned into a simple Transcript and let go of the local image name for the display window. Also, did transcript := Transcript. displayForm := (ImageMorph fromString: 'Display has not yet been installed') form. in StackInterpreterSimulator initialize. So, here is the current stance: | vm | StackInterpreterSimulator initializeWithOptions: Dictionary new. vm := StackInterpreterSimulator new. vm openOn: 'C:\MinGW\msys\1.0\home\User\pharo\pharo.image'. vm openAsMorph. vm run. the morph opens. Now, when I do run, I do get a problem in: InterpreterStackPage>>headFP: pointer There is an self assert: (pointer = 0 or: [pointer < baseAddress and: [realStackLimit - (LargeContextBytes / 2) <= pointer]]). And LargeContextBytes is nil. I looked around for initialization for that one. It is only in the InterpreterStackPage class >> initialize So I did; | vm | StackInterpreterSimulator initializeWithOptions: Dictionary new. vm := StackInterpreterSimulator new. InterpreterStackPage initialize. vm openOn: 'C:\MinGW\msys\1.0\home\User\pharo\pharo.image'. vm openAsMorph. vm run. Then I got a blinking square running in the top corner. No amount of stopping processes would interrupt it. So the simulator is running the run loop: self fetchNextBytecode. [true] whileTrue: [self assertValidExecutionPointers. atEachStepBlock value. "N.B. may be nil" self dispatchOn: currentBytecode in: BytecodeTable. self incrementByteCount]. and relinquishing processor every once in a while and this square is shown (Display reverse below] ... (which is where I end up when interrupting) ioRelinquishProcessorForMicroseconds: microseconds "In the simulator give an indication that we're idling and check for input." Display reverse: (0@0 extent: 16@16). Sensor peekEvent ifNotNil: [self forceInterruptCheck]. Processor activeProcess == UIManager default uiProcess ifTrue: [World doOneCycle]. microseconds >= 1000 ifTrue: [(Delay forMilliseconds: microseconds + 999 // 1000) wait] ifFalse: [Processor yield] If one could tell me how to get the display to show, it would be welcome. The display instVar contains stuff in the debugger but isn't ok to open with something like: In the transcript, I do see things related to initialization: (56) Looking for primitiveSetGCBiasToGrowGCLimit in vm Looking for module ... not found (3751) Looking for primitiveFileWrite in FilePlugin Looking for module FilePlugin (3751) Looking for secCanCreatePathOfSize in SecurityPlugin Looking for module SecurityPlugin ... loaded (3751) Looking for secCanDeletePathOfSize in SecurityPlugin (3751) Looking for secCanGetFileTypeOfSize in SecurityPlugin (3751) Looking for secCanListPathOfSize in SecurityPlugin (3751) Looking for secCanSetFileTypeOfSize in SecurityPlugin (3751) Looking for secDisableFileAccess in SecurityPlugin (3751) Looking for secCanDeleteFileOfSize in SecurityPlugin (3751) Looking for secCanOpenFileOfSizeWritable in SecurityPlugin (3751) Looking for secCanRenameFileOfSize in SecurityPlugin (3751) Looking for secHasFileAccess in SecurityPlugin ... loaded (3774) Looking for primitiveFileSize in FilePlugin (4390) Looking for primitiveCompareString in MiscPrimitivePlugin Looking for module MiscPrimitivePlugin ... loaded (4623) Looking for primitiveDirectoryDelimitor in FilePlugin (7806) Looking for primitiveIndexOfAsciiInString in MiscPrimitivePlugin (57216) Looking for primitiveStringHash in MiscPrimitivePlugin (177977) Looking for primitiveFindFirstInString in MiscPrimitivePlugin (179055) Looking for primitiveFileOpen in FilePlugin (179815) Looking for primitiveFileGetPosition in FilePlugin (179832) Looking for primitiveFileAtEnd in FilePlugin (179873) Looking for primitiveFileRead in FilePlugin (182837) Looking for primitiveFileSize in FilePlugin (182868) Looking for primitiveFileSetPosition in FilePlugin (186627) Looking for primDigitCompare in LargeIntegers Looking for module LargeIntegers ... loaded (186688) Looking for primDigitMultiplyNegative in LargeIntegers (186884) Looking for primNormalizeNegative in LargeIntegers (186985) Looking for primDigitAdd in LargeIntegers (186986) Looking for primNormalizePositive in LargeIntegers (187038) Looking for primDigitSubtract in LargeIntegers Is there a way to stop the interpreter in order to debug things? I saw: runAtEachStep: aBlock self initStackPages. self loadInitialContext. self internalizeIPandSP. self fetchNextBytecode. [true] whileTrue: [self assertValidExecutionPointers. aBlock value: currentBytecode. self dispatchOn: currentBytecode in: BytecodeTable. self incrementByteCount]. localIP := localIP - 1. "undo the pre-increment of IP before returning" self externalizeIPandSP How to use that? Why do I not see the display in the sim? I saw a "quitBlock". What is this about? I am not far from getting this working... Thanks for some clues!

Hi guys When I published the ConfigurationOfBitmapCharacterSet-StephaneDucasse.4 it got fully empty and this worries me. Not only because I lost what I did but because I have no idea why. Stef

Hi pavel may be I should start from your miniimage and start to making sure that the configurations can load then in a second step I can make sure that they can unload. What do you think? Stef

ConfigurationOf
by Torsten Bergmann Nov. 27, 2013

Nov. 27, 2013

In Pharo 3.0 there is a new class "ConfigurationOf" which I can subclass for my configurations. But then my config is not loadable in Pharo 2.0. The problem is that when people migrate the configs often are adopted for Pharo30 and still work for Pharo20. So one can use this new shiny common superclass only for new Pharo 3.0 configs onwards or is there a backport planned ... Thx T.
