What I would like to see is - what is the API in terms of vocabulary (ie drop the same as reject) - can we reexpress some of our iterators? what is the cost? Stef

Positive experience report porting from StHub to GitHub

Hi guys, I just want to report that I started to migrate some of my projects from to GitHub (for example https://github.com/hernanmd/ApplicationSecurity and https://github.com/hernanmd/StringExtensions) in Pharo 6.x Basically the steps are: 1) Install the Peter Uhnak git-migration package: Metacello new baseline: 'GitMigration'; repository: 'github://peteruhnak/git-migration/repository'; load 2) From (GitBash) command-line: cd /c/Users/{your_git_project_directory} git log --oneline -n 1 3) Execute this script: | migration | migration := GitMigration on: '{your_sthub_user}/{project_name}'. migration cacheAllVersions. migration authors: { 'Your_Name' -> #('Your_Name' '<your_mail(a)mail.com>')}. migration fastImportCodeToDirectory: 'repository' initialCommit: '....' " copy/paste the id from the git log command in step 2)" to: 'import.txt' 4) git fast-import < /.../import.txt git reset --hard master git add * git commit -m "fast-import from SmalltalkHub" git push {project_name} or git push Let me know if there's something you would add to the workflow.
