And I found that fundamental operations on the .git directory could be composed to implement Git API commands. For example: implementing checkout. Read the current HEAD, get the commit hash it points at, read the commit object, read the commit tree content and convert the content to an index. Repeat for the branch to be checked out. Diff the two indices. Write that diff to the working copy. Write the name of the branch being checked out to HEAD. Convert the commit being checked out to an index. Write that index to the index file.

You run git clone . ../beta. This creates a new directory called beta. It initializes it as a Git repository. It copies the objects in the alpha objects database to the beta objects database. It points the master branch on beta at the commit object that the master branch points at on the alpha repository. It sets the index on beta to mirror the content of the first commit. It updates your files - number.txt - to mirror the index. 2ff7e9595c
