This is my implementation of Jit, from James Coglan's book Building Git.
Build the rug binary and add it to your PATH:
$ cargo build
$ export PATH=/path/to/rug/target/debug:$PATHSwitch to the directory you want to track using rug:
$ mkdir /tmp/rug-test && cd /tmp/rug-test
$ mkdir -p foo/bar
$ echo "hello" > hello.txt
$ echo "world" > foo/bar/world.txt
Finally, initialize a Git repo and create a commit:
$ rug init
$ rug add .
# Currently, this waits for your input. Type in your commit message
and hit Ctrl+D
$ rug commit
You should now be able to use Git to view the commit you just created:
git show
