tonel-migration

Pharo utility to migrate FileTree repositories to Tonel

Prerequisites

• git installed in the system and available in PATH
• Pharo 6+ (at least 60518)

Installation

Metacello new
	baseline: 'TonelMigration';
	repository: 'github://peteruhnak/tonel-migration/repository';
	load.

Usage

"in Pharo"
sourceRepository := IceRepository registry detect: [ :each | each name = 'tonel-migration-demo' ];

targetLocation := FileLocator home asFileReference / 'prog' / 'tonel-migration' / 'migration-target'.

"if the location doesn't exist"
targetLocation ensureCreateDirectory.
repo := IceLibgitLocalRepository newRepositoryAt: targetLocation subdirectory: sourceRepository subdirectory.
repo init.

TonelMigrationRunner new
	sourceRepository: sourceRepository;
	targetFile: targetLocation / 'import.txt';
	migrate

# in terminal
cd ~/prog/tonel-migration/migration-target
# import.txt is the file that you've created earlier
git fast-import < import.txt
# fast-import doesn't change the working directory, so we need to update it
git reset --hard master

You should see the changes, and git log should show you the entire history.

Git Tips

Forgetting all changes in the history and going back to previous state. Useful if the migration is botched and you want to rollback all changes.

$ git reset --hard SHA
