[Pharo-project] String, ByteString and WideString
by Andrey Larionov Aug. 1, 2010

Aug. 1, 2010

Working with WebClient i found what it lacks of non latin languages support (for example Russian). During investigation i found, what for streaming there used ByteString, which is custructed by calling String class>>new:. All subclases of String by calling of this method produces only ByteString instances. Also WriteStream>>contents indirectly calls String class>>new:. So even you construct WideString with #basicNew: calling (WideString basicNew: size) writeStrem contents produce only ByteString Is this a bug or there some workaround? Thanks. -- Andrey Larionov

[Pharo-project] CogVM as official Pharo VM?
by Mariano Martinez Peck Aug. 1, 2010

Aug. 1, 2010

Hi folks. Hope Eliot is reading this thread. It is time to think in Pharo 1.2 and we need to discuss if we want to have CogVM as the standard Pharo VM. Most of us have tried it and found it incredible fast. So it would be very good to take advantage of it. But I think there are a couple of things to be discussed: 1) Cog VM seems to be aimed for x86 and 32 bits. You can read Eliot quotes: "The Cog VM is a just-in-time compiler that currently supports only x86 No effort has been made to maintain 64-bit compatibility. Apologies, this was unaffordable." So...how much important is this for us? do we care? and if we want to do it, is it "doable" ? is it less doable than the normal squeak VM ? I really would like to have 64bits VM + 64bits images in a near future...but hat's just my thoguhts. 2) The status of the external plugins. Are they working with Cog ? Not only the "core plugings" but FFI, OSProcess (I read some problems with it), TrueType, etc... 3) Is it stable for production use? For example, I read that with seaside there are some crashes. 4) Depends on heroes. I never liked this idea. It has nothing to do with Eliot. He is very cool and helpful. But I wonder, do we understand the new VM and the changes? are we able to handle and fix it even without eliot ? 5) Integration to VMMaker. I saw that they started to merge cog (actually, I think only stack vm?) to the trunk of VMMaker. This is really good news. I hope everything is there and merged. 6) Binaries. It seems the official released didn't come with binaries. So we should compile it for each OS. Ok..that's all my thoughts. I would really like to have a discussion here and see what to do.....grrrrrr you are all in holidays, aren't you? hahah cheers Mariano

[Pharo-project] More on autotest
by Alexandre Bergel Aug. 1, 2010

Aug. 1, 2010

Hi Laurent! One thing with autotest. When I compile a method, even though it is not covered by the tests, the tests are run again. This does not always make sense I feel since it slow down the way I code... For example, when I am defining a meta-model, then running the test each time I add some business method it makes sense. However, when I define a mondrian visualization, all #visualize have to be excluded by autotest.

[Pharo-project] Pharo 1.1/1.2 and class names in Chinese
by empty July 31, 2010

July 31, 2010

In 1.1 and 1.2, without setting a language environment for Chinese, I am able to use Chinese by setting fonts. It seems to work except for accepting a class named in Chinese will end in a ClassBuilder error of 'Class names must be capitalized'. Well is it a feature(requires language environment being set correctly) or bug? The code located being: validateClassName: aString "Validate the new class name" aString isSymbol ifFalse: [ ^ false ]. aString first canBeGlobalVarInitial ifFalse:[ self error: 'Class names must be capitalized'. ^false]. environ at: aString ifPresent:[:old| (old isKindOf: Behavior) ifFalse:[ self notify: aString asText allBold, ' already exists!\Proceed will store over it.' withCRs]]. ^ true and following the code the problemic method is #canBeGlobalVarInitial: which is found in two classes: in EncodedCharSet class side: canBeGlobalVarInitial: char | leadingChar | leadingChar := char leadingChar. leadingChar = 0 ifTrue: [^ self isUppercase: char]. ^ self isLetter: char. and in LanguageEnvironment canBeGlobalVarInitial: char ^ Unicode canBeGlobalVarInitial: char. I didn't set a Chinese environment and the exception is occured in in EncodedCharSet class since leadingChar is 0 and a Chinese char seems thought to be lowercased. ----- åç¡ä½ åç¡æ³ åç¡å§ -- View this message in context: http://forum.world.st/Pharo-1-1-1-2-and-class-names-in-Chinese-tp2305496p23… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] Conflic between Shout and PluggableTextMorph in Pharo 1.2
by Mariano Martinez Peck July 31, 2010

July 31, 2010

Hi. If you try to load Shout, you will have the error: 'styler is already defined in PluggableTextMorph' The problem is that the Shut class PluggableShoutMorph subclass PluggableTextMorph. PluggableShoutMorph has its own instVar 'styler' which PluggableTextMorph doesn't have in Pharo 1.1 But in Pharo 1.2 (I don't know why) PluggableTextMorph has its own instVar 'styler'....thus, the problem. Of course, if I remove the instVar 'styler' from PluggableShoutMorph it shoud load...but I am not sure if this is the correct action. Thanks for the help in advance Mariano
