Have you ever wondered how Git works under the hood? I did - so i created lit.
Lit implements some of git's basic functionalities in less than 1000 lines using only the Go standard library.
It currently supports basic versioning of a directory using commits, creating and switching to branches as well as displaying the commit history of a specific branch.
The binary can be built using go build. Running the command lit init will initialize the repository in the current directory.
The following commands are currently supported.
lit init will initialize the repository in the current directory.
$ lit init
Initialized empty Lit repository in /home/nlulic/.lit
lit commit -m <msg> will create a commit of the current working tree. The commit message is optional and the author and committer will always be a default user called anonymous.
Note: The output will print all files that are in a directory where a change was detected - not just single files that changed.
$ lit commit -m "initial commit"
[master (commit 1f5f518003d52205d7af3ae6bfe71104a0a217bd)]
2 files changed:
created/updated .litignore

lit log will display the commit history of the current branch.

Just like in Git, specific files and directories can be ignored. Simply add a .litignore file to the root directory.
# directory
.git/
# binary
*.exe
