I removed that in pharo since it was a hack working only on squeak and not even well because what happens if I do an alias to self obj := self. obj pvt.... or with passing a ref to me around and client invoke the method. aA foo: self A>>foo: aA aA pvt For people that want to read a nice paper on private methods I suggest: Encapsulation in a dynamic language by nathanael scharly => only self send (using self keywords could be potential private call) I like the idea and the reasoning behind. and freezable traits to a certain extent Stef > > Hi > > Am 2010-11-02 um 10:24 schrieb eMko: >> There is a convention of naming private methods - instead of naming it just >> "methodName" you can use "myMethodName". >> >> I have seen this convention in some tutorials at squeak wiki but have not >> seen a system class in squeak or pharo which uses this.

Private methods
by Jeff Gray Nov. 2, 2010

Nov. 2, 2010

Coming from doing a lot of java and C#, a lot of my classes' internal processing would be done with private methods. Is there a similar mechanism in smalltalk? I suspect I may be thinking about this all wrong :-) -- View this message in context: http://forum.world.st/Private-methods-tp3022981p3022981.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Minimum spec
by Jeff Gray Nov. 1, 2010

Nov. 1, 2010

I run Pharo on Win7 on a netbook and it works well. The only issue I have is the "intellisense". When I start typing a message it offers me some options in a list. To select anything but the first in the list takes upwards of 15 seconds. No biggy and I can certainly work round it. Is there a minimum spec for Pharo? -- View this message in context: http://forum.world.st/Minimum-spec-tp3022984p3022984.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

IF you get some answers I;'m interested to know it because we are thinking about what is a VM API to monitor them. > At the moment I have several projects in parallel. Nearly all of them are web based. I use a cherokee server on my local machine that starts a squeak image whenever I access a project via web browser. For persistency I use piers image based persistency. But I don't want to have all of the images run all the time. I would like to shutdown images if they aren't accessed for some time. > I could do it via seaside but then I don't want an image to shutdown while I'm working on the image and not accessing seaside.

How to detect an inactive image?
by Norbert Hartl Oct. 29, 2010

Oct. 29, 2010

At the moment I have several projects in parallel. Nearly all of them are web based. I use a cherokee server on my local machine that starts a squeak image whenever I access a project via web browser. For persistency I use piers image based persistency. But I don't want to have all of the images run all the time. I would like to shutdown images if they aren't accessed for some time. I could do it via seaside but then I don't want an image to shutdown while I'm working on the image and not accessing seaside. What is a good measure of activity inside the image? thanks, Norbert
