Re: [Pharo-project] Feature request for Opal

Ok, the change was rather trivial, most of the functionality was still there. I committed Name: Compiler-LukasRenggli.242 Author: lr Time: 29 September 2010, 8:29:05 am UUID: 5e237cdd-b72f-44ae-a6c9-402623dfb670 Ancestors: Compiler-MarcusDenker.241 - use pragmas to make primitives extensible to the Pharo inbox and the issue tracker (http://code.google.com/p/pharo/issues/detail?id=3014) Image recompiles without problems. Same tests fail as before. For the other Smalltalk that use the same infrastructure I've attached a change-set.

Re: [Pharo-project] After loading a package...all changes with "revision changed"

by Javier PimÃ¡s

If you get that case, an idea that should work is to modify Behavior>>#compile:classified:notifying:trailer:ifFail: method (or someone like it) to insert a breakpoint that only halts when the new code is the same than the existing one. Then you could trace back who is recompiling existing code without your knowledge Regards, Javier.

Depends what level.... At a high level you could use OSProcess to invoke the correct Python command line and do it in a different process. Or you could use some socket protocol if you have a python interpreter already running waiting for commands. or a mixture of the two... At a lower level you could look to link Python as a C library. cheers, Mike On Tue, Sep 28, 2010 at 10:56 PM, Alberto Bacchelli <alberto.bacchelli(a)usi.ch> wrote: > Hi, > > Â Is there any way to make Pharo and Python communicate? > > Thanks, > Â Alberto > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >
