Thanks for this Alistair. Having more self contained package options, is good. I'm also interested in the upcoming Nix package initiative that has been announced in the list recently, which also deals with installing dependencies in a Linux distribution neutral fashion. Cheers, Offray On

[Pharo-users] Pharo 6 snap install

Hi Everyone, I've made a snap package for Pharo 6 which I think is far enough along for some wider testing. To get Pharo up and running on Ubuntu 16.04: # Install Pharo $ sudo snap install --edge pharo --classic # If your system isn't configured for threaded heartbeat: $ sudo pharo.config #

Re: [Pharo-users] Traits, method flatten

Investigating a bit on the mater, here is the conduct: - In a fresh 5.0, find an a version of my package where the Traits logic is not compromised (All traits methods are not duplicated in the classes using the traits) - Load this package, all seems fine. - Promote the class/trait category to a

Re: [Pharo-users] why is adding instance variables so slow?

Hi, in non spur, the only improve that I think it can be made safely is moving the garbage collect operation to the migration of instances side, only executing the garbage collect if there are instances. In spur the garbage collect it is not needed anymore, because the way the become is

Re: [Pharo-users] Recommended stable Pharo 5.0 VM for Linux users?

yes, at the end I did a different process. after cloning vm sources, now you do not need to generate them… just go to $ cd build.linuxWHATEVER/pharo.cog.spur/build $ ./mvm that will work and produce the official latest VM :) Esteban > On 12 Apr 2017, at 09:59, Luke Gorrie

[Pharo-users] why is adding instance variables so slow?

Hi, does anyone know why adding instance variables is so slow? I did some quick benchmarks (see below), resulting in more than order of magnitude speed difference between having it in the class definition and adding it later. In fact it is still much faster to delete the class and then
