We still use regular names for the classes - but for the tools they have a distinguishable ID. Best is to use a UUID for the ID as it is unique from the beginning. So if you create a class "Foo" and I create one both are unqique by ID - even when using the same name. The "rest" is implemeting tooling support. When you write "Foo" in a workspace then the workspace either already has a naming context to resolve the name (see [1] or could provide you with a selection if there is more than one. Internally you could bind to the right class by using the ID. I hate prefixing the classes as we now do, I want to name the classes "Instruction" not "IRInstruction" in Opal or "AJInstruction" in AsmJIT, especially since "IR" and "AJ" do not really tell you anything. Smalltalk names should be understandable. Additionally we should have meaningfull (and also unique) names also for namespaces. Also the current three/two letter prefixing of classes that is used in Squeak or Pharo only scales well for small communities... When there are things I like in Java then it is the fact to use reverse domains for namespaces. It is easy, understandable and I could also easily check if there is a web location. This way a namespace "org.apache.maven" gives you something meaningful, I can even visit http://maven.apache.org/. Allows the community to easily scale with thousands of classes without having clashes. Think of "org.pharo.asmjit.Instruction" vs "org.pharo.opal.Instruction" So you additionally need better and meaningful namespaces THAT SCALE AND ARE EASY TO UNDERSTAND combined with real packages (as objects, as Pharo already has). Then we also need ABIA (Around, beginner, inner, after messages), multiple method categories, selector namespaces, possibility for visibility (like private methods, see [2]), unified annotations for classes/methods/variables and a few other ingredients from my personal wishlist and it may shape a different new future... The interesting part is not to add all kind of stuff to Smalltalk - the interesting part is what is the most minimalistic system to allow for something extensible and still flexible (even within the meta-system) so that one can bootstrap things on top.

Packaging Pharo for many distributions at once

by Damien Cassou

Hi, I've packaged Pharo VM for the Nix package manager which can be installed on many Unix (e.g., Linux, MacOS X and FreeBSD). This works well but requires installing Nix on your Unix. Another solution is http://openbuildservice.org. Is any of you interested in trying to use this service to build Pharo VM packages for several Linux distributions automatically? I can help.

[ANN] I stop maintaining the Ubuntu packages

by Damien Cassou

Dear all, I've recently switched my Linux distribution from Ubuntu to NixOS. This means I can no longer maintain the Ubuntu packages and their PPA (https://launchpad.net/~pharo/) These packages need a maintainer! The good side of it is that it is not a lot of work as I did all the automating infrastructure: https://github.com/pharo-project/pharo-ubuntu. Basically, the maintainer will have to launch a few shell scripts regularly (once a month for example). I will obviously be available to help the new maintainer. The community needs *you*. Good news is: I packaged the Pharo VM for the Nix package manager which can be installed on many Unix (e.g., Linux, MacOS X, FreeBSD). And NixOS will have the Pharo VM package in its next release in October! -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

Monticello commit hook

by fmusi

Hey guys, I'm new here with Pharo and Monticello and I want to extend the commit's functionality. Can you lead me to which classes or methods do I have to start looking for making Monticello execute some code of mine whenever it does a commit? Thanks in advance. -- View this message in context: http://forum.world.st/Monticello-commit-hook-tp4779799.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
