[Pharo-project] Debugging code with morphic leads to freezes and a weird message
by phil＠highoctane.be June 25, 2012

June 25, 2012

While debugging actions behind buttons, I do get Project class>>spawnNewProcessIfThisIsUI: not being understood. This prevents from debugging interactions properly. And sometimes I get the dreaded "Computation Terminated" message, effectively locking me out of the image (nothing moves anymore, I've got to kill the process). Ideas on how to fix? This is 1.4 14438 -- Philippe Back

[Pharo-project] fulltext method search
by Camillo Bruni June 25, 2012

June 25, 2012

I was bored today (after yet another kernel panic) so I implemented a quick fulltext search for methods. "this takes around 1.5mins" Search default buildIndex. "this is an instantaneous (~2ms!) search over all method sources" Search default matchSentence: 'Convert to a String with Characters' I think we should integrate that into some kind of "SpotLight" search for accessing the sources much much faster... The current draft is available here: http://smalltalkhub.com/#!/~dh83/spotlight

[Pharo-project] Strangest object ever seen?
by Pavel Krivanek June 25, 2012

June 25, 2012

Hi, If you take the latest Pharo 2.0 image from Jenkins (20059) and you execute the expression: (Metaclass allInstances select: [:c | c superclass = ProtoObject class]) inspect you will get an collection inspector where the first object is very strange one. It is very hard to get any useful information about the origin of this evil object. The only thing we know exactly is that it causes virtual machine segmentation faults while trying to export class ScrollBar via Fuel. Not only CogVM but even StackVM. Can you, please, try to help us to get as much information as possible about this object? I named it "dzindzik" :-) Cheers, -- Pavel

I am looking for a VM support to open up on configuration atleast 2 if not more as possible windows ( surfaces to paint morphs on). Viz: I run the dev code / browsers etc on one panel and designate the other window as the runtime panel to popup runtime windows only

[Pharo-project] Opal ?
by Goubier Thierry June 25, 2012

June 25, 2012

Hi, I'd like to port an old smalltalk code tracer framework of mine to Pharo (was developped on the VisualWorks compiler) and I didn't manage to port it easily on the Pharo smalltalk compiler. I met J-C. Arnaud in Rennes yesterday and he told me I should try the Opal compiler. So, how do I load Opal in a Pharo 1.4 image ?

Hi, I've a very long array I'd like to inspect, unfortunately inspector shows only first 100 elements and few last elements of my array. How can change that behavior?

[Pharo-project] Some Nautilus feedback
by Torsten Bergmann June 24, 2012

June 24, 2012

some feedback on Nautilus: 1. Having "Class/Instance" in one button is bad since the label can mean two things: "Im on the class/instance side" (state like) "Click here to go to class/instance side" (action like) After a while one knows it is the latter but this is really confusing anytime I come back to it. Especially since all Smalltalks I've used in the past have a clear and better distinction. Displaying the state on the title of the window is not enough. Possible solution: - reintroduce the two buttons (if layout space is a problem use "Instance" "?" "Class" where ? points to comment - use Tabs as in Dolphins browser http://www.stevewaring.net/blog/images/ssosxCHB.jpg - use a real toggle button which is not only changed but have a pressed "Instance" or non-pressed "Class" state - use two Radio Buttons as in VisualWorks http://linuxgazette.net/issue51/gx/steffler/classBrowser03.jpg 2. I like the hierarchy view ... and the double click "navigate to" functionality that is similar to VisuaWork. But still the inheritance tree view is not collapsible which is the most missing feature. You may ask why do we need that. Here is an example: navigate to class "StandardWindow" in Pharo 2.0 and click on "Hierarchy" to have a class hierarchy browser. Now you want to learn more about the direct subclasses of "StandardWindow" - hard to do in Nautilus: You will see class DialogWindow as the first subclass if SystemWindow - since the hierarchy of DialogWindow itself is very deep you can not see and easily navigate to the second subclass of SystemWindow which is "FontChooseMorph". It is hard to scroll down and since the tree has not lines it is also hard to follow indentation. With a collapsible tree you could collapse the "DialogWindow" subtree and would see - SystemWindow -- DialogWindow (collapsed) -- FontChooserMorph -- NautilusWindow Attached is a screenshot to show how easy it would be displayed with a collapsible browser (I used the SmalltalkMT class hierarchy browser to mock it) 3. The casing in the menue items is totally inconsistent. Here an example: "Find Method..." "Add class..." Nonetheless I like Nautilus a lot - thanks for it!
