Git with style presented Iceberg, a front-end for git built using filetree and libgit2. Iceberg aims to smoothly transition Pharo development to git, allow development directly in git, and grow functionality incrementally. Version 0.4 was recently released and integrated into Pharo6 as a preview. The presentation demonstrated using Iceberg for solo and team development on a shared repository. Upcoming version 0.5 will address 64-bit support, multiple directories, cherry-pick, and other issues.

1. Git with style
by Esteban Lorenzano

2. Today is
no-release
day!

3. What is iceberg
• A front-end to work with git using
- filetree
- libgit2
• Yes, it can be other things tomorrow, but now is
that.

4. Presented to you by

5. Iceberg goals
• Nicely move Pharo into git world
• Allow Pharo development itself on it
• To grow incrementally
- Starts with some few use-cases
- Add functionality as needed
- That’s why there are a lot of functionality missing
• Extensible

6. Why
• Monticello is showing age
• With time, the “package” metaphor became
insufficient.
- We now use more complex “projects”
- Programs often have different kind of sources

7. Iceberg status
• Version 0.4 released last week, and integrated
into Pharo6 as preview.
• Tested in several projects and working (some
minor problems on different platforms)
• It will work to develop Pharo7, so it should work for
you too.
• Hot-fixes will be incorporated (I already have a
couple on the works)

8. Use-cases we have in mind

9. Solo

10. clone work commit push

15. Team on unique
repository

16. clone
branch commit push
pull
work Pull request

25. Distributed team

26. clone
branch commit push to fork
pull from
origin
work Pull request
FORK

33. Demo
(The Pharo process)

34. Pharo process in a nutshell
• Clone from pharo-project/pharo
• Create a branch with issue number (or feature
name)
• Work on it as needed
• Push to your fork
• Submit a Pull Request to “development” branch

35. Near future (v0.5)
• Work on 64bits (requires move to libgit2 0.25.1)
• Support for multiple directories (allow subtrees)
• Support for cherry-pick
• fix filetree export properties problem
• it should be there ~1 month from now

36. Thanks!
