by Blondeau Vincent

Hi, It is *automatic* :) You just setup the location of both pre and spur images in the launcher. It will find in the image header the one it should use.

Re: [Pharo-users] Launcher 0.2.9 opens Spur images

by Yuriy Tymchuk

But how does it work? Doest the launcher detect which vm should be used for the image that you are launching, or you have to switch something?

Launcher 0.2.9 opens Spur images

by Damien Cassou

Hi list, thanks to the awesome work of Vincent Blondeau, Stephan Eggermont and Cyril Ferlicot, Pharo Launcher 0.2.9 can be configured to open both spur and pre-spur Pharo images. You can download this version from http://www.smalltalkhub.com/#!/~Pharo/PharoLauncher. You can safely replace your existing Launcher installation with the new one. Your images won't be affected and you will still be able to launch them. The VM coming with these builds is a pre-spur VM because Launcher is based on Pharo 4. If you want to launch Pharo 5 spur images, you need to separately download a Pharo 5 Spur VM from http://get.pharo.org/vm50 and configure the location of this VM in the Launcher settings (icon at the bottom left of the Launcher window). What I like about this release is that I didn't do anything but changing the version number in https://ci.inria.fr/pharo/view/all/job/Launcher :-). -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm." --Winston Churchill

Re: [Pharo-users] Spec: Populating a playground with a particular content (was Re: Spec: Binding widgets how to)

by Offray Vladimir Luna CÃ¡rdenas

Hi Nicolai, That was the issue. Now it's working! I was trying to test different combinations to see why UI updating was not happening but I got the variations wrong (one true, another false, instead of both false :-) ). The next step I'm working on in populating the GTPlayPage with some particular content. In my previous interface I made something like this: -[1]--------------------- GrafoscopioBrowser>>panelAsCodeFor: aNode "Shows an interactive playground for Smalltalk code in a node body" browser := GLMTabulator new. browser title: 'CÃ³digo'. browser column: #code. browser transmit to: #code; transformed: [ GTPlayPage new content: aNode body ]; andShow: [ :a | a custom: GTPlayground new ]. browser sendToOutside: #nodeBody from: #code -> #text. ^ browser. ------------------------ In this one I tried some variation of GlamourPresentationModel>>glmPres that let the user predefine a content for the GTPlayPage like this: -[2]---------------------- glmPresWithContent: aString glmPres isNil ifTrue:[ glmPres := GTPlayground new startOn: (GTPlayPage new content: aString)]. ^glmPres --------------------------- but if I try running the interface with this//I get: "MessageNotUnderstood: GlamourPresentationModel>>content:", so I think that something more is needed to create Playgrounds in the Spec-Glamour that are pre-populated with content. How can I create a playground inside a Spec-Glamour interface that is already populated with a given content?

Very nice, this is important. Would you be interested to have your article included in https://medium.com/concerning-pharo ? If so, I believe you have to submit it and then I can accept it.

A Turing Machine simulator written in Pharo

by Julien Delplanque

Hey everyone, I had a course named "Calculabilty and Complexity" last year and I implemented a Turing Machine simulator using Pharo just to see how easy/hard it would be (it was quite easy :) ). I also wrote a little thing on medium about it [1] (I just took half an hour to review it and I thought it was time to publish it). Just announcing it in case it case someone need/is interested by this. There is also a github repository for the source code [2].

It is written against an API from Mac OS System 7, from before Mac OS X, that is an OS from last century, ~199X.

On linux the CA of the apple server is installed system wide. The SSL plugin code only looks for the certificate and the key but not for the CA. So under linux it finds it in the system but on Mac OS I couldn't do the same.

In the Mac code there is /* Disable cert verification since we do that ourselves */ status = SSLSetEnableCertVerify(ssl->ctx, false); I don't understand the comment. But reading it I think this would "solve" the problem as well :) Norbert
