An Exciting XP: Roassal 30 on top of Bloc

Hi, today we connected with Milton and recovered the branch from mid-2021(github/Roassal3:bloc).

We started by merging current Roassal3 master on top of the bloc branch, then had to update the code
that changed due to evolution of Bloc and of Roassal3, and also remove the dependency to Spec-Brick backend,
which was used only to show the examples.

It can be loaded in a P11 with:

[ Metacello new
     baseline: ‘Roassal3’;
     repository: ‘github://ObjectProfile/Roassal3:bloc’;
     load: ‘BlocFull’ ]
           on: MCMergeOrLoadWarning
           do: [:warning | warning load ]

Easy find examples at:
– browsing instance-side of RSBlocExamples class
– evaluating “RSExamplesBrowserPresenter exampleOpenRSBlocExamples”

Cheers,
Martín
