[Pharo-project] System announcements and MC
by Sean P. DeNigris April 22, 2012

April 22, 2012

I subscribed to the ClassModifiedClassDefinition announcement to be notified when an inst var is added to a class, but I get notifications when MC is loading things. This seems like a very different type of event than when one manually adds an inst var via the browser, but I don't see a way to tell which is happening based on the contextual info the announcement gives me.

[Pharo-project] probably modal problem
by StÃ©phane Ducasse April 22, 2012

April 22, 2012

Hi guys when I open 1.4 and I use the default browser edit a method then do not accept it click on another method. I get prompt (method promptForCancel) and the discard or accept do not work. I think that there is a problem with exception or something like that. Apparently the method confirm: 'Code has been modified.\What do you want to do?' translated withCRs trueChoice: 'Accept' translated falseChoice: 'Discard' translated cancelChoice: 'Cancel' translated default: nil. never returns it seems that findContextSuchThat: is sent to nil. I tried to understand if this is related to the introduction of a breakpoint in the method but I do not think so. calleeOf: aContext "Return the context whose sender is aContext. Return nil if aContext is on top. Raise error if aContext is not in process chain." suspendedContext == aContext ifTrue: [^ nil]. ^ (suspendedContext findContextSuchThat: [:c | c sender == aContext]) ifNil: [self error: 'aContext not in process chain'] promptForCancel "Ask for the appropriate action to take when unaccepted contents would be overwritten." | choice | choice := ( UIManager default confirm: 'Code has been modified.\What do you want to do?' translated withCRs trueChoice: 'Accept' translated falseChoice: 'Discard' translated cancelChoice: 'Cancel' translated default: nil ). choice ifNotNil: [ choice ifTrue: [ self accept ] ifFalse: [ self model clearUserEditFlag ]] => confirm: queryString trueChoice: trueChoice falseChoice: falseChoice cancelChoice: cancelChoice default: defaultOption "Put up a yes/no/cancel menu with caption queryString. The actual wording for the choices will be as provided in the trueChoice, falseChoice and cancelChoice parameters. defaultOption should be one of true, false or nil to set the default button.

Re: [Pharo-project] How can I do literate programming?
by Stephan Eggermont April 22, 2012

April 22, 2012

You should probably use a MOOSE image if you want to do the modern equivalent of literate programming. Instead of comments, drive your code from (behavioural) tests, create glamour & mondrian browsers to visualize the design and quality attributes of the code and use magritte style descriptions to declaratively describe your domain. Then generate LaTeX & pictures from this for the paper trail. Stephan Eggermont

Re: [Pharo-project] The video about Athens
by Fernando Olivero April 22, 2012

April 22, 2012

Athens is an API, the rendering is actually done by the backends. Currently Ballon and Cairo are supported. So, the answer is that Athens is supported in all platforms using the Ballon backend, (note that ballon does not have all the features of Cairo, so some of the features in the demo wont work), and the Cairo backend as well. You just need to tell NativeBoos were to locate the cairo library (built using MacPorts, so the path starts at /opt/...). For now we just hardcoded the library path (you can change them by hand for now, to point to your local Cairo lib) TCairoLibrary class>>nbLibraryNameOrHandle ^ '/opt/local/lib/libcairo.2.dylib' AthensSurface class>>nbLibraryNameOrHandle ^ '/opt/local/lib/libcairo.2.dylib' This should be changed, perhaps a settings?

[Pharo-project] Kernel jobs for 2.0
by Pavel Krivanek April 22, 2012

April 22, 2012

Hi, I created Kernel jobs for the version 2.0. It uses separate set of scripts so new big changes will not break 1.4. https://ci.lille.inria.fr/pharo/view/Pharo-Kernel%202.0/ Now is pointless to run them because 2.0 repository doesn't include all packages. Some things that should be done: - start Trello board for 2.0 ;-) - the package Deprecated 14 should be replaced by Deprecated20. - integrate basic Fuel packages (Fuel, FuelMetalevel, FuelPackageLoader + tests) -- Pavel

[Pharo-project] [ANN] Physical Etoys 2.0 released!
by Ricardo Moran April 22, 2012

April 22, 2012

Hi everybody (and sorry if you receive multiple copies), I would like to announce a new version of Physical Etoys, now with a lot of new features: 1. First of all, it's based on Etoys 5.0 so it incorporates all the bug-fixes and new features from the Etoys release. 2. We are now focusing on the two main hardware platforms: Arduino and Lego Mindstorms Nxt. For the rest, we will publish a set of "external modules" that you can install in your Physical Etoys version. 3. Also, we now support an argentinian version of Arduino, which is called DuinoBot and it's currently being used in a lot of argentinian schools. 4. We added new devices for arduino and now we also support the use of digital devices attached to analog pins. 5. We added two new objects that let you graph the input of a variable across time and save it to a csv file. 6. We added a new programming mode that lets you compile your scripts and have them running inside the robot, in contrast to running them in the computer and communicate with the robot via bluetooth or usb. We believe this opens a lot of new posibilities for the Physical Etoys users. 7. And finally, we fixed a lot of bugs that make the software a lot more stable (or so we hope :). I would like to use this opportunity to publicly thank all the people from the Etoys community for their work on Etoys 5, this latest version is much better than the last and I encourage you all to try it. And also, I would like to announce that Physical Etoys 2.0 is going to be installed by default on all the laptops of the "Conectar igualdad" program, which is kind of like the argentinian version of OLPC (but for older students). So we are *really* excited about this! Now that you're all as excited as we are :) you can download and try Physical Etoys 2.0 from our blog: http://tecnodacta.com.ar/gira/projects/physical-etoys/. Cheers, Richo

[Pharo-project] Can I get a "image save" notification?
by HwaJong Oh April 22, 2012

April 22, 2012

My program wants to detect image save event. I couldn't find one, so changed SmalltalkImage>>logChanged: or SmalltalkImage>>addSnapshot:andQuit: to detect the image save and fire my custom notification. Is there a good for doing this like SystemChangeNotification or SystemAnnouncement?
