Re: [Pharo-dev] New Iceberg Version 1.2.1

by Damien Pollet

First of all, quick stupid question: I'm currently loading my code with gitlocal://./src as the repository URL (my workflow starts in a terminal rather than in a Pharo image) Should I just remove the /src part, now that my repo has the project metadata? Also, are more features planned for the .project file? E.g. what about storing a default selection for Calypso and the Test Runner in there?

Look at any ruby or maven project, they all have strong conventions for organizing projects and standard config files for deviating from those conventions. I would have preferred if Iceberg picked one convention (arbitrarily) in the absence of a .project file instead of forcing its explicit presence. IMHO the choice of default directory per se (be it ./, ./src, ./source or whatever) matters less than the fact that there is a convention in place. > - I donât see why there needs to be a 1:1 relationship between a > repository and working copy in pharo.

If you want separate source dirs it kinda means that you want separate change histories, doesn't it? What if the same class has diverging definitions in separate directories (I wonder what maven does in that caseâ¦)? On the other hand, separate source directories would be helpful to work with git-subrepo and similar toolsâ¦ -- Damien Pollet type less, do more [ | ] http://people.untyped.org/damien.pollet

The one thing is not be able to run the CI. The bigger problem is that pharo is not buildable at all. Can we please move mission critical repos like epicea to github?

We try to not do any destructive operation without asking the user first (that's why we have several preview windows for pushing, pulling, checkout, merge..., and why contrastingly with monticello we show the committed changes on the commit window...). So, instead of transparently "adding the file" we have decided to modify the project in memory and let the user the responsibility to commit that file. > > If there's a drawback, is that the repository is marked as dirty.
