Re: [Pharo-users] [OT] RTalk

by dimitris chloupis

yes I thought I made this clear in my first post, the reason why I find RTalk so tempting is that it does not only offer the language but also the environment which AFAIK redline does not. Please correct me if I am mistaken, but I have not seen redline docs/wiki mention the enviroment anywhere and I have to say that smalltalk environment is pretty much the reason why I chose smalltalk and not so much the language. ________________________________ From: Geert Claes <geert.wl.claes(a)gmail.com> To: pharo-users(a)lists.gforge.inria.fr Sent: Tuesday, 30 October 2012, 12:54 Subject: Re: [Pharo-users] [OT] RTalk for Smalltalk on the JVM there is Redline Smalltalk I thought ...

[OT] RTalk

by dimitris chloupis

I found this http://www.jarober.com/blog/blogView?showComments=true&printTitle=IM_98:_Rt… ,about RTalk , that is not only smalltalk run on top of JVM but almost the entire environment.Â The problem is that I cant seem to be able to find via google any site that contains the source code or something I could use ? Does anyone know if there is any official website for RTalk ? It looks quite promising and I would like to give it a try.

garbage collection questions

by Paul DeBruicker

1. Is there a wiki entry about the GC somewhere that provides advice about how to tune the GC using #setGCParameters? 2. If I have two objects with accessors: Object subclass: #ObjectA instanceVariableNames: 'objectB' classVariableNames: '' poolDictionaries: '' category: 'Temp' Object subclass: #ObjectB instanceVariableNames: 'objectA' classVariableNames: '' poolDictionaries: '' category: 'Temp' and create an instance of each in a workspace and then set them up: |a b| a:=ObjectA new. b:=ObjectB new. a objectB: b. b objectA: a. and close the workspace then those instances of ObjectA & ObjectB will never be garbage collected, correct? Its my understanding that I'd need to nil out the instance variables of both instances to have them GCd as they both refer strongly to each other. Is that right? 3. How can I learn when an incremental or full GC run will happen? Is it dependent upon on the size of new or old memory or the overall size of the image or ... ? It seems like putting a #halt in a random spot could easily lead to a stuck image. Thanks for your help Paul

Regex search and replace with groups

Hi there, I'd like to remove a slash from a string like this one: 'abc123/456def/ghi' The resulting string should be 'abc123456def/ghi' that is only slashes surrounded by numbers should be removed. I tried with regex and group, using something like: 'abc123/456def/ghi'copyWithRegex: '(\d)/(\d)' matchesReplacedWith: '$1$2' but of course it doesn't work, dollar sign doesn't identify the group, sigh.
