shit == Shell Git
This is an implementation of Git using (almost) entirely POSIX shell.
Caveats:
- There are a couple of GNU coreutilsisms, which are marked with "XXX: GNUism" throughout. They have been tested on BusyBox as well.
- A native zlib implementation is required: zlib
- Why the fuck would you use this
Enough plumbing commands are written to make this write the initial commit with itself, which is how the initial commit was written. Huzzah.
- Don't
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 ../shit.
To create a new index from all of your files (note, subdirectories aren't working yet):
../shit/update-index *
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 protected]"
../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
Tada.
