[ANN] Pharo bootstrap
by Christophe Demarey Feb. 29, 2016

Feb. 29, 2016

Hi all, In case you do not know, we work on bootstrapping Pharo, i.e. create a Pharo image from sources, not based on a previous image (well, we use a pharo image to produce it but no code / state from it). This process will allow to define a minimal Pharo kernel (currently 52 packages but we could have it far smaller) and to modularize the whole image (currently packages have too much dependencies on packages already loaded into the image). The bootstrap process also allows to write down the recipe to initialize a new image from scratch (some code is missing in the image or is wrong). In addition, I think we will clean a lot of historical objects that are not used anymore. With the amazing work done by Guillermo Polito during his Phd (around Espell, Oz): https://guillep.github.io/files/publications/Poli15Thesis.pdf, we succeeded to get a first prototype of a bootstraped Pharo 5 image (from 5.392). This prototype is able to run an eval command line handler and to log output / errors. Not all classes are yet initialized and you cannot yet save / restart this image but it is a big step forward. It is a 4 mb image (could be half the size without unicode data). You can download it at: http://chercheurs.lille.inria.fr/~demarey/pmwiki/pub/pharo-bootstrap/pharo-…. Next steps are to have a bootstrapped image fully working, then to load packages on top of it (like network, sunit) to produce a minimal image. Then, we need to implement an Oz VM on top of Spur. After that, we need to work on a reliable way to build the bootstrap (not too sensitive to changes in the image).

Call for Spec Examples
by stepharo Feb. 28, 2016

Feb. 28, 2016

Hi guys I started to group the Spec material in a github pillar project. I should add the dynamic chapter of stephan. Julien is preparing some examples and what would be good is if you have some tips and tricks we could add a chapter to collect them. https://github.com/SquareBracketAssociates/BuildingUIWithSpec Stef

[ANN] OSUnix and OSLinuxUbuntu on new UFFI
by Torsten Bergmann Feb. 27, 2016

Feb. 27, 2016

These two projects (who were based on NativeBoost in Pharo 4) are now updated to new UFFI in Pharo 5 which means they are loadable in recent Pharo 5 image and all tests pass. So if you are working on Linux/Unix you might wan to check them out in latest Pharo 5 by loading them from Catalog browser. A BIG THANKS to Esteban for helping me in the conversion and updating the new Unified FFI (UFFI) according to the issues that were found during the conversion. More is in the pipe ... step by step it goes! Bye T.

Re: [Pharo-dev] [bloc] feature envy -> move method close to data?
by Tudor Girba Feb. 27, 2016

Exactly. This is a sensible point. We need to learn a bit more from concrete implementations on top of Bloc before we decide. @Alex: Could you add a flag in the implementation? Doru p.s.
