Re: [Pharo-users] Defining Prerequisites in Packages

by Runar Jordahl

Thanks for your answer. I have read this document and I know that dependencies can be defined in Metacello configuration classes. I guess I question whether this is the best location to store package dependencies. If, for example, I were to port my integration with DTangler to Pharo, I am unsure how the tool will be able to find dependencies for a given package. Would it need to search though ConfigurationOf-classes? How would it determine the correct version to use, etc? Maybe it can be done, but it would be harder than VisualWorksâ approach were you have this information directly in the package. Also consider that you might want to query dependencies not just for a single project (like Seaside), but for the entire image. Using a single ConfigurationOf-class, might not be sufficient. Then again, I do not have much knowledge of Pharo. Maybe Pharoâs approach makes sense once I start using itâ¦ Is my understanding correct when I expect Pharo to continue having package dependencies only defined in Metacello configuration classes? Kind regards Runar Jordahl

Defining Prerequisites in Packages

by Runar Jordahl

I notice that it is possible to define prerequisites between packages using Metacello. However, I have not found a way to specify prerequisites directly in packages themselves. Is it correct that there is no mechanism available for defining prerequisites on Pharo packages? Are there any projects that will try to address the lack of prerequisite information on packages? Will for example âRingâ include this? I have made a tool for visualizing dependencies between VisualWorks packages. In VisualWorks the prerequisite information is found directly at instances of classes representing package versions (PackageModel). The tool mixes visualization of the defined/specified prerequisites and computed/calculated prerequisites. I think I once read about a tool for Pharo to compute/calculate prerequisites. Does anyone know which tool this is? Information about my VisualWorks dependency tools can be found here: http://blog.epigent.com/2012/03/analyze-dependencies-in-visualworks.html I am using Pharo 1.4 together with the Nautilus browser. Kind regards Runar Jordahl

Pharo Consortium Important Documents and Request for Feedback

by StÃ©phane Ducasse

Dear Pharo Friends and Supporters We worked a lot with INRIA lawyers and tried a lot of different scenarios. We arrived to a setup that make sense now we would like to get your input. Please have a look at the following powerpoint presentation and feel free to comment! We provide some sketches for the consortium fees and benefits for you. But we need your input! If you are not in the mailing-list: send us a mail to board(a)pharo-project.org. Remember that what we want to achieve is to be able to pay one (or more) full time engineer to help us improving our system and making that our future is bright. Since it may be difficult to follow closely our vision, dreams and current development efforts you can read the Pharo vision document. https://gforge.inria.fr/frs/download.php/30436/PHARO-ENG-V4.2.pdf https://gforge.inria.fr/frs/download.php/30434/PharoVision.pdf The Pharo Team Remember: The best way to predict the future is to invent it. A. Kay And we want to do it :)

This is simple. ConfigurationOf are for your project. (think objects) Anybody should go there and find it and ouahhhh it works. Now when a configuration is ready copy it to the metacelloRepository. I will send soon a doc named Pharo vision. Read it It is explained inside :).

To fix the problem that the tools won't be on the path, what if we use symlinks to the arduino tools? Would that work? Or simply registering the arduino tools in the PATH variable?
