leGit

a stripped down implementation of git written in go

Description

a small Git implementation that's capable of initializing a repository, creating objects in /.git (blobs, trees) and creating commits

Commands

1. init - to initialize a leGit repo
2. cat-file <blob_sha1> - to read a blob object from it's sha1 hash
3. hash-object -w - to create a blob object of the file
4. ls-tree <tree_sha1> - to read all contents of leGit tree object (type of object, name, sha1 hash)
5. ls-tree --name-only <tree_sha1> - to read all the files' names of a leGit tree object
6. write-tree - to make a tree object from the files that exists in current directory
7. commit-tree <tree_object_sha1> -p <parent_commit_sha1> -m <commit_message> - to write a commit based on the passed tree object with parent commit reference, author's creds and an optional commit message

Testing locally

The le_git.sh script is expected to operate on the .git folder inside the current working directory. If you're running this inside the root of this repository, you might end up accidentally damaging your repository's .git folder.

I suggest executing le_git.sh in a different folder when testing locally. For example:

mkdir -p /tmp/testing && cd /tmp/testing
/path/to/your/repo/le_git.sh init

alias leGit=/path/to/your/repo/le_git.sh

mkdir -p /tmp/testing && cd /tmp/testing
leGit init
