shit == Shell Git
This is an implementation of Git using (almost) entirely POSIX shell.
XXX: GNUismthroughout. They have been tested on BusyBox as well.
Enough plumbing commands are written to make this write the initial commit with itself, which is how the initial commit was written. Huzzah.
Okay, fine. Because only plumbing commands are implemented, you have to live with a garbage manual process. Do something like this:
git clone https://git.sr.ht/~sircmpwn/shit mkdir my-project cd my-project ../shit/init # Write some code
So we'll assume shit is at
To create a new index from all of your files (note, subdirectories aren't working yet):
Then to create a tree object from these:
../shit/write-tree | ./hash-object -t tree -w
This will print the tree ID to stdout. Use that to make a commit:
export GIT_AUTHOR_NAME="Your Name" export GIT_AUTHOR_EMAIL="email@example.com" ../shit/commit-tree <tree sha> | ./hash-object -t commit -w
This will print out the new commit's SHA. To update master to point to this new commit:
echo <commit sha> > .git/refs/heads/master
