How can I save a project on GitHub to SmalltalkHub?

by Juraj Kubelka

Hi, How can I save (from time to time) project packages hosted on GitHub to SmalltakHub? The reason is that I do not want to force people to install GIT when they want to install a project. So I am thinking to regularly deploy it on SmalltalkHub and update ConfigurationOf. Thanks in advance, Juraj

"self problem" with Ghost (virus)

by Steven Costiou

Hi, I use virus from Ghost to intercept messages sent to a given object and adapt methods behaviors for this particular object only. However it would seems that doing interception this way is subject to the "self problem" described in this paper from StÃ©phane (DUCASSE, StÃ©phane. Evaluating message passing control techniques in Smalltalk. _JOURNAL OF OBJECT ORIENTED PROGRAMMING_, 1999, vol. 12, p. 39-50). I understand i could do instance based adaptation using an other technique, but i wonder if there is any way with Ghost to deal with this "self problem" problem ? Steven.

Re: [Pharo-users] Changing method definition at runtime

Ben's solution worked perfectly for me. Thanks! Also I had a look at Stef's article but still need to read it more carefully. Thank you all for the references and advice!

magritte extras

by Sean Glazier

I am looking at creating a tool that works like the magritte example. It uses Magritte-XMLBinding. I ran the tests and had a small number of failures in Magritte-Tests-XMLBinding. The example class MADescriptionEditor is in the examples tag of the Magritte-Seaside package. It came from Repository: http://smalltalkhub.com/mc/Magritte/Magritte3/main/ and the XML binding for the examples comes from Repository: http://smalltalkhub.com/mc/Magritte/Magritte3Addons/main/ So if someone has these working and playing together that would be great. If it is outdated and we are to use something else I would like to know what the preferred way is so I can build the example building the descriptions using I guess json. Many thanks :-) Kind Regards, Sean Glazier

Re: [Pharo-users] Spec: Capturing changes in a text morph

by Johan Fabry

No, this is not in initializePresenter, since this is called only once, when the window is opened. Instead, you need to do this every time that the widget is changed. So in your code where you change the widget to a new one, I guess this is changeBody: , you need to configure this new widget. -- Does this mail seem too brief?

Re: [Pharo-users] Spec: Capturing changes in a text morph

by Offray Vladimir Luna CÃ¡rdenas

Thanks Johan for your quick answer. Your hypothesis is right and the contents of (4) are cleaned by a new widget when I click at the tree (2). I'm looking at my code and documentation, but I can't find properly how to implement your recommendation. I imagine is somewhere in initializePresenter, but I can't find the place... sorry I would like to be more helpful on getting help... :-/. Any hint of how this code should look like and where it goes? "body whenTextChanged: aBlock" on initializePresenter seems doing nothing.
