A small re-implementation of git (a distributed version control system) written in Rust:
- basic commands:
init,config,add,commit,status,diff,log. - branches:
branch,checkout,merge. - remotes:
clone,fetch,push,pull,remote. - plumbing:
hash-object,cat-file,ls-files,read-tree,write-tree.
$ cargo build --release
$ cd target/release
$ ./gitrs$ mkdir repo
$ cd repo
$ gitrs init
Initialized empty Git repository in .git
$ gitrs config --add user.name "John Doe"

$ echo 'Hello world!' > file_a
$ gitrs status
new: file_a
$ gitrs add file_a
$ gitrs commit -m "first commit"
[master 5b0cd52] first commit

Cloning into copy

$ gitrs commit -m "second commit"
[master 3940393] second commit

$ gitrs branch new_b
$ gitrs pull copy_remote master

$ gitrs checkout new_b
Switched to branch new_b
$ echo 'new line' >> file_a
$ gitrs status
modified: file_a
$ gitrs diff
file_a:

$ gitrs add file_a
$ gitrs commit -m "third commit"
[new_b 9e4e36b] third commit
$ gitrs checkout master
Switched to branch master
$ gitrs merge new_b
Merge new_b into master
[master 7b8e051] Merge new_b into master- Pro Git book

I wanted a fun project to learn more about the Rust programming language and git inner workings at the same time. The sole purpose of this project is educational. As a challenge I also restricted myself to the Rust standard library, thus re-implementing everything else that I might need such as: sha-1 hash function, zlib compress/decompress functions, etc. This is absurd and definitely not good practice, but again the only aim was to learn, so every opportunity is a great excuse to code in Rust!
