VMs version name

by Francois Stephany

Is there a way to identify a VM with a version number like an image? When I download the latest 'Pharo.app' it says "Pharo VM 6.0-pre". It's the same name that the VM I downloaded one month ago. Is there something like the image name (e.g, "2.0-497") I can use to tell someone to use a given VM version? Cheers, Fa

Script Manager

by Torsten Bergmann

In Pharo 1.4 you just open the configuration browser: - either by evaluating "MetacelloConfigurationBrowser open" or via menu "Tools"->"Configuration Browser" - when it is open search for "ScriptManager" in the list of available Configurations, then select it and right click to choose "Install Configuration (Stable version)" from the context menu - now go to "Tools" -> "ScriptManager" Same procedure in Pharo 2.0 Bye T.

cmd +W the problem is that using shift make the short cut difficult to do. I have a lot of problem with cmd-b+cmd-N It does not work with me 50% of the time.

Re: [Pharo-users] How do i list the execution order of statements inside a method?

by Mircea SamoilÄ

Thank you for taking the time to explain this in such technical detail. I reread my answer to the example StÃ©phane Ducasse gave me, and i realize some of you might have gotten the impression in never fully understood the code and what i meant. I may lack the technical background to express this, but i did fully figure out what it meant and how it would help me. Gathered more "intel" form other sources. "Check out our AST interpreter that will give you fine-grained control over the execution of Smalltalk code. With underlying AST as execution format it is very easy to map the currently executed code back to the source code." http://smalltalkhub.com/#!/~dh83/ast-interpreter The keywords contained in the answer have indeed assured me that in am indeed looking into the direction. I've since compiled a list of all the things i am supposed to know before i can attack the problem myself, and happily started my journey to knowledge. Conceptually i think i have the solution, as all the pieces seem to be available, but i think it will take some time before i slowly transition this mental model to a "working" model, given my lack of practical expertise. I have high hopes that what i'm trying to achieve will also help alleviate some of the caveats OO has now, a rather opaqueness of objects, a "hiding" of relevant information behind something else, and the need to "know" the model of all the separate packages involved, but which you don't actually need to build something rather small in between. I find it rather peculiar that it is in this field also, the best advice of how to fix things comes from people complaining. I found this http://blog.jot.fm/2010/08/26/ten-things-i-hate-about-object-oriented-progr… I may not share the expertise of the writer but i can say, with confidence, that i am quite familiar with the feeling.
