Charles I do not have the energy to type all the things I would like to say. So if one day we cross at ESUG I can take a blackboard and explain it. Now in a nutshell The problem is that nested classes implies a really different organization and infrastructure. If we late bound classes then we should copy code (binding are shared between litearl and namespace).... I do not want to enter into the details. Then you end up with the question of "ah ok the superclass is not known at compile time" -> mixin infrastructure: how do I avoid to copy all the code (copy down of accessors and only using accessing....). Then about namespaces. I do not like VW namespaces - I do not like class level import. Now the point is not about namespaces per se. the problem is twofold: - do we want real modularity or just something for nameclash. if you want nameclash, I do not see why prefix are not simpler For real modularity it means that you define your code in isolation and bind the name after in a bind statement and that your scope protect you (for example what happen if the super class is now bound to a class that by accident has the same instance variables than the class you just defined). So you see it changes a lot. - Now the infrastructure (compiled, browser..... should not use Smalltalk globals but environment everywhere so that we can explore namespaces and modules design. So all the people wanting namespaces should be clear for what for themselves first? what is the engineering cost? do they are ready to put this cost on the table? or what other improvement is less important? help just to get tools been able to work on a different environment. So if you payed attention we started since 2002 or even before removing all the Smalltalk at: and turning them in self environment, now recently we got Smalltalk globals and even more recently we got SystemNavigation working on environment instead of hardcoding Smalltalk globals... Having envoironment -based tools (without having namespace in the languages since this is a different issue) will support: system bootstrap atomic loading compiler bootstrap better modular system So let me conclude: - we have a vision - we are not sure what is the best solution (namespace vs. true module) - we are working on the infrastructure so that at least we can prototype some solutions So I hope that may anwser is ok because I will not say more. 1.2 is waiting for us to get born.

You can't create a class in smalltalk without assigning a category to it, so, a developer, who just started with smalltalk, are forced to use categories anyways. Yes, and the fact that nested classes systax like in Ruby or other languages are possible, because they using a 'source files' , which is single bloat of code. While in smalltalk, you usually operating with single method at one moment of time, and all browser operations and UI are optimized around that simple idea, so you don't need to scroll endless file with source code to find the method or nested class you are looking for at line #10974. > > > -- > View this message in context: http://forum.world.st/Nested-classes-tp3125667p3159885.html > Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com. > > -- Best regards, Igor Stasenko AKA sig.

Igor: Let me preface that I pay my bills doing VisualWorks by day and we have namespaces. Yeah, I'm not sold on them but several languages have them and so I wondered what I was missing. In a way if you could use them to constraint the instantiation of a nested class to only occur within a outer class it may have some merit i.e. an arm can only exist in the context of a body etc, but how value does it add ? From my perspective traits adds value and its worth its cognitive overhead, not sold on nested classes. "you can just do: Body Leg new. and in Body>>#Leg answer any class you want to play role as 'Leg'. Or you missing double colons in the middle? :) " I missed something here ? , in Ruby the syntax is: Body::Leg.new I guess you are saying that in Smalltalk I can just setup the accessors to return whatever plays the role of a Leg but part of the point is that the Leg class is defined within a Body class and I guess if you are looking a source file in Ruby that might be helpful :) i.e. class Body class Leg def method1 end end end The fact that Ruby and other language developers are not used to browser categories maybe makes this helpful in some way. -- View this message in context: http://forum.world.st/Nested-classes-tp3125667p3159885.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

What I always do is select the text (suppose 'tabs'), right click -> extended search -> method source with it the problem is that is seraches in all the image, not a particular package. So...having this, integrated in RB, and being able to select a scope would be awesome (maybe it is present already) ...update.... I have just check and there is something "literals matching" in RB....so maybe for literals at least it works. Maybe it would be nice to extend it so that it works like "method source with it".

This 'nested classes' to me look like nested namespace(s), and nothing more. I'd rather introduce namespaces in smalltalk rather than nested classes. But while having a long background of languages which having namespaces, i could not say that i miss them in smalltalk too much.

how to find all occurrances of a string in a package?

Re: [Pharo-users] Nested classes

by Charles Monteiro

the first I heard of traits was indeed I believe from a paper by Stef's group if I recall correctly. So that's exactly what I mean. Nested classes are an organizational and a "structural" construct. A nested class is defined from within an outer class. They are used when a class is only likely to be instantiated (used) from within another class. For example (just an example) , when you instantiate aBody you would want to instantiate two legs but two legs outside the context of a body may not make sense. So that seems of some value. You can also used it to simply group classes i.e. an outer class Drawing, may specify inner classes Line, Circle, Rectangle etc. To instantiate an inner class you need special access syntax in Ruby you would do something like this: aCircle = Drawing::Circle.new ok, that's alright if I'm using nested classes to group. but you can also do this: aLeg = Body::Leg.new but wait I thought you it only made sense to instantiate a Leg from within the context of a body. Anyhow, I sort of have mixed feelings about it i.e. if they are worth the extra overhead. Not to mention that Smalltalk's IDE's are not setup to handle them. File based IDE's of course don't care, they just care about the source representation. -Charles www.nycsmalltalk.org -- View this message in context: http://forum.world.st/Nested-classes-tp3125667p3159802.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Hi Laurent I've read there is a couple of system calll monitors in MacOS, ktrace and dtrace (http://en.wikipedia.org/wiki/Ktrace , http://en.wikipedia.org/wiki/DTrace) so you may attach to the VM and see what's missing?

On 64bit systems you just need to load the 32bit libs by installing the package 'ia32-libs'. On Debian and Ubuntu you can just apt-get install ia32-libs then the one-click app will work just fine. I imagine its the same package name on other distros but I don't know for sure.

Incorrect cursor behavior in right-to-left scripts

by Alex Albitov

Hi all, I noted incorrect cursor behavior in right-to-left script. When right-to-left script (Hebrew for example) is used the cursor should not advance to next character, but stay in its position and let the characters advance as the text is being inserted. Does anybody knows how to change the cursor's behavior? Thank you, Alex Albitov

Thanks Hernan. It still doesn't work. I've also tried to play with LD_LOAD_PATH / LD_LIBRARY_PATH no success.... I want to make it work so I need to learn :) For the mangled function names, on Linux and OSX there's nm. Here's what I get: $ nm -g libyaz.3.dylib | grep ZOOM_connection_create 0000000000046a30 T _ZOOM_connection_create Cheers, Laurent On Sun, Dec 19, 2010 at 6:23 PM, HernÃ¡n Morales Durand < hernan.morales(a)gmail.com> wrote: > Hi Laurent, > > Thanks for reporting.

Re: [Pharo-users] [Pharo-project] serial driver

by Lukas Renggli

On Unix/Linux systems you can just read/write the respective device files. That worked in my case.
