[ann] bloc & cairo+morphic
by Tudor Girba May 11, 2017

May 11, 2017

Hi, We are happy to announce that based on the work of Glenn, Alex extended Bloc (Sparta) to work directly in the Morphic world using Cairo as a backend. Cairo is less powerful than Moz2D (see the screenshot below for an example), but the implementation addresses a concern that the community raised regarding a perceived increased liability due to the dependency to Moz2D. Essentially this means that Bloc can be treated as another graphical library that can coexist with Morphic without requiring any external VM plugin. I would also like to point out that adding a new backend and host was possible because of the many iterations (including throwing away whole implementations) that Alex and Glenn went through. I think they did an amazing job. You can find a bit more details about Bloc here: http://www.humane-assessment.com/blog/bloc-flexible-backends-hosts/ Another issue raised regarding Bloc was that of the engineering effort required to make it a reality. That is why I would also like to announce that Alex joined feenk.com where he is primarily working on the graphical stack for Pharo. Cheers, Doru -- www.tudorgirba.com www.feenk.com "To lead is not to demand things, it is to make them happen."

Where can I get a working SourceCity? Even in older Pharo/Moose. I've got a use case for metrics that would be a pretty good fit. Philippe

Remote Debugger bugs ?
by Steven Costiou May 10, 2017

May 10, 2017

Hi, i'm confused with how to configure the remote debugger. I used this link to configure my images: http://dionisiydk.blogspot.fr/2017/01/pharmide-pharo-remote-ide-to-develop.… I evaluated "1/0" in a playground in the remote image, and the exception opens in my local image. Now if i clic "abandon", the local image is ok but the remote is frozen. If i clic "proceed", the local image is frozen and the remote is ok. So using the remote browser from my local image, i created a test class with a test method that does "^'1', 0" and i execute it in the remote image. The debugger opens the local image and i can debug it "^'1', 0 printString", accept and proceed. The inspector opens with the return value in the remote image and the local image is frozen again. The only solution i have is to kill the image. I used Windows 7 for these tests. Is there anything i missed besides the configurations steps in the link above ? RemoteBrowser and RemotePlayground seem to work fine, except some problems with the contextual menus in the browser.

Working with remote debugger: how to debug something happening in the remote image ?
by Steven Costiou May 10, 2017

May 10, 2017

While configuring my local and remote images to work with the remote debugger, there was a bug with the menu in the remote browser. So i wanted to try the debugger and figure out what was the problem using it, but i do not understand how to proceed. When the debugger opens, all i see is the fact that there was a remote problem, and that the proxy was unable to return a proper value. I used a local image connected with a headless remote image. To reproduce the bug, go for example in ByteString >> at:put:, right click after the first dot and click "debug". See suggs-menu-bug.png. When doing that i get debug-win.png and suggs-debug.png and as you can see i just know there was an error and what it was but i don't have an open debugger as i would normally expect in Pharo. How can i see the real problem occuring in the remote image ? How can i remotely fix this considering that my remote image is headless and it seems to be a problem tied to the remote thing, because locally it doesn't happen ? (or maybe it is a Calypso problem but anyway i cannot debug it...) Steven.

Epicea vs RB refactorings
by Peter Uhnak May 10, 2017

May 10, 2017

Hi, I'm under the impression that Epicea is supposed to replace RB refactorings at some point. If that is true, is it currently possible to build refactorings by hand? For example in RB I often do: ``` model := RBNamespace new. model defineClass: ('<1s> subclass: #<2s><n><t>instanceVariableNames: <3p><n><t>classVariableNames: ''''<n><t>poolDictionaries: ''''<n><t>category: <4p>' expandMacrosWith: 'Object' with: 'MySomething' with: 'var1 var2' with: 'MyPackage'). cls := model classNamed: #MySomething. cls compile: 'var1 ^ var1' classified: 'accessing'. (ChangesBrowser changes: model changes changes) open ``` or (removing a method from a class) ``` model := RBNamespace new. model removeMethod: #testTrimRight from: StringTest. (ChangesBrowser changes: model changes changes) open ``` Thanks, Peter
