Re: [Pharo-project] How do i import .MCZ into Squeak?

by Mariano Martinez Peck

What Henrik says is correct. You can also take a Pharo dev image from here: http://www.pharo-project.org/pharo-download That images already contains AST, RefactoringBrowser, etc. You should be able to load there also. 2010/4/6 Henrik Johansen <henrik.s.johansen(a)veloxit.no> > > On Apr 6, 2010, at 7:45 32AM, James Ladd wrote: > > Hi Pharo, > > I got the .MCZ package installed, but there is a dependency on > RBProgramNode > which I can't find. > > I'm looking for the package / source for RBProgramNode, which I think could > just > be a image version issue.

This could be a problem with the coverage analysis. You have to be extra careful with coverage analysis on system classes like collections and filestreams, because they are used everywhere.

(Or browse the package and see what you need to load manually in baseline/version methods). The ProgramNode class itself is in the AST-Core-Nodes package. Kind of hard to tell if that is all you need though, as the link you provided leads me to the squeaksource frontpage...

Re: [Pharo-project] A port of Pharo: Redline Smalltalk ...

by StÃ©phane Ducasse

Yes this is the vision we have. Now if people would help for simple things in pharo we would have more time for such issues. We got several people doing PhD on modules and related. We studied namespace and other kind of points so we have an idea of what could be a solution but it should be implemented tested.....

Re: [Pharo-project] Redline Smalltalk

by StÃ©phane Ducasse

Hi dan This is fun because I was rereading the miniimage contents and started to think in terms of package reorganization to support a mini image. I reread also Spoon a bit and I was looking at the nuturning. Dan it would be nice if you could merge the potatoe change into Jsqueak? Dan, Mariano for his PhD did some analysis about number of object used during typical coding session and we got around 17 %. So mariano would like to see how we can get something like LOOM to dispose unused objects :) Stef > James Ladd <james_ladd(a)hotmail.com> wrote... >>> Hi Pharo-ites, >>> >>> I'm working on a port of Pharo to the Java Virtual Machine called Redline Smalltalk. >>> (read more here: http://jamesladdcode.com/?p=323) >>> >>> I'm wanting to port every single class over time, but initially enough to get the >>> compiler working and have a minimum runtime. >>> >>> Of the 1600+/- classes which are those necessary to make a small workable compiler >>> and runtime environment? > > Hi, James - > > Bert Freudenberg forwarded this along to me, as I'm not on a Pharo mailing list. > > I think you know of my JSqueak project (a.k.a.
