Re: [Pharo-project] Using WebClient

by GermÃ¡n Arduino

Talking of post method, I tried to capture it with Firebug to understand what data post with WebClient, but no way until now. Exist some trick to obtain the exact content of the data to post only debuggin the web page?

Â It might be enough to decide the content of that and send it over the socket.

[Pharo-project] Manuia Memory Monitor

BTW: There is also the old "MemoryUsage" from Squeak (see [1]/[2]).

Would it be possible to do: ManuiaMonitor>> initialize graph := MMGraph new. graph addProbe: MUsedMemoryProbe new; addProbe: MMGCProbe new. (and only window addMorph: graph in the open method) and remove self addProbe: MUsedMemoryProbe ... from MMGraph initialize? That way, a graph not used by the monitor is empty by default, and a new instance can be used for whatever graphing purpose one desires, like Mariano :)

Hi Norbert, Mariano, there is a quick way to see which classes are using traits. Inspect the following expression: Smalltalk allClasses select: [:cls| cls hasTraitComposition and: [cls traitComposition size > 0]] On 31 May 2010, at 10:15, Mariano Martinez Peck wrote: > Hi Norbert: I am not sure the current situation in Squeak but in Pharo I know it is used in some places. > > I think in some Collection testing and Nile framework...but I am not sure. > > Anyone can help? > > Cheers > > Mariano > > ---------- Forwarded message ---------- > From: Norbert Fortelny <norbert.fortelny(a)gmail.com> > Date: Wed, May 19, 2010 at 5:17 PM > Subject: [squeak-dev] traits > To: squeak-dev <squeak-dev(a)lists.squeakfoundation.org> > > > Could anyone point me to sample code using traits in squeak. > Poked around a bit but couldn't find anything. > thanks and sorry if that is inappropriate here. > Norbert > > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project -- Johan Fabry jfabry(a)dcc.uchile.cl - http://dcc.uchile.cl/~jfabry PLEIAD Lab - Computer Science Department (DCC) - University of Chile

Hi Norbert: I am not sure the current situation in Squeak but in Pharo I know it is used in some places. I think in some Collection testing and Nile framework...but I am not sure. Anyone can help?

Alexandre: Is there a way (or will be in a future) a way to script and customize it ? Suppose I want to trace several things, not only the amount of memory used. I would love to be able to define my own curves and have several at the same time. Maybe what I need is just that graph but totally customized for me. Any hints?
