doesNotUnderstand: infinit loop
by Hilaire March 17, 2017

March 17, 2017

Hi, My Pharo4.0 image is in a situation where each MNU exception throw from a DNU result in infinite loop, locking the image, even not breakable with alt+[.]. >From the doesNotUnderstand: message, the "exception reachedDefaultHandler" always returns true, and it results in the execution of the true block, sending again the original message to the original object, repeating a DNU and so on. Any idea how to fix that? Thanks Hilaire doesNotUnderstand: aMessage "Handle the fact that there was an attempt to send the given message to the receiver but the receiver does not understand this message (typically sent from the machine when a message is sent to the receiver and no method is defined for that selector)." "Testing: (3 activeProcess)" | exception resumeValue | (exception := MessageNotUnderstood new) message: aMessage; receiver: self. resumeValue := exception signal. ^exception reachedDefaultHandler ifTrue: [aMessage sentTo: self] ifFalse: [resumeValue] -- Dr. Geo http://drgeo.eu

Moving from Slack to Discord
by Dimitris Chloupis March 9, 2017

March 9, 2017

I have been aware about Discord for some time now , but I never used it because both Pharo and Unreal channels are on Slack. From my small experience with it, it seemed much more superior to Slack with added bonus that is completely free (open source ) and with no restrictions unlike Slack. But something happened suddenly yesterday, I opened Unreal in Slack and it was gone with a notification that they moved to Discord. So I grabbed this opportunity to create a Pharo server you can join here https://discord.gg/F6nAd Discord works as web apps but also you can download as an app for Windows, Macos , iOS and Android. I will be around in Discord because I generally browser Unreal channels. The nice thing about Discord also is that it offers both audio and video chat for free which can work great for Pharo sprints. Anyway there is no harm on testing it.

by Dominique Dartois March 8, 2017

March 8, 2017

In the Seaside book, chapter 17.2 I read I can include a stylesheet this way : updateRoot: anHtmlRoot super updateRoot: anHtmlRoot. anHtmlRoot stylesheet url: 'http://seaside.st/styles/main.css' On my development machine (macOS) I use http://localhost:8080/myApp as the server address and I donât know the root directory of the Seaside integrated web server. Can anyone help me to find this directory? Thanks. --- Dominique Dartois

Proof of Concept: FileTree and Fossil
by Pierce Ng March 1, 2017

March 1, 2017

Hi all, I have written a simple integration of FileTree with Fossil to avoid the 2-step Pharo- and shell-level work to add/delete/commit files. At the operating system command prompt, init a new Fossil project: os% mkdir ~/repo os% cd ~/repo os% fossil init myproject.fossil project-id: 3c05c3016eeabf8e87816ee218c6a86d3c87b950 server-id: ff42bc86dba1a26b1d94b64685f7c09d02581617 admin-user: laptop-user (initial password is "1fe2ff") Open the repository: os% mkdir ~/myproject os% cd ~/myproject os% fossil open ~/repo/myproject.fossil In a fresh Pharo 6 image - I used v60411 - install FossilFileTree: Metacello new baseline: 'FossilFileTree'; repository: 'github://PierceNg/FossilFileTree'; load. Write code in Pharo. Open Monticello Browser. Add a "fossilfiletree" repository, using ~/myproject as the directory. Save to said repository from within Monticello Browser. Done.

How to capture the execution of a playground?
by Offray Vladimir Luna CÃ¡rdenas March 1, 2017

March 1, 2017

Hi, I would like to store the object resulting from executing a playground. This would imply two steps: - Knowing that the playground content was executed (via the play button or its shortcuts Ctrl + Shift + g or Ctrl + g). - Getting the results of that execution. For example if the result at the end is a string or a dictionary, I would like to get that string or dictionary. Any pointers on how to make that will be welcomed. Cheers, Offray Ps: I still get lost when I search by myself trying to answer questions like the ones above. I imagine that in some way is related with evaluationAction and presentations, by looking for the source code of "do it and go", but still I can't get a functional code snippet to start prototyping.
