MyGit

MyGit is a Git-like command-line tool written in C.

Build the Docker Image

To build the Docker image:

make docker-build

Alternatively, running make all or simply make will also build the image.

Run the Application

To run mygit commands inside a Docker container:

make run ARGS="<command> [<args>]"

For example, to initialize a new repository:

make run ARGS="init"

To hash a file named example.txt and write it to the object store:

touch example.txt
echo "hello world" > example.txt
make run ARGS="hash-object -w example.txt"

To view the content of an object (replace <object_hash> with the actual hash):

make run ARGS="cat-file -p <object_hash>"

The .git directory used by the application inside the Docker container is mapped to .git_docker_data on your host machine. This allows you to inspect the Git data created by mygit.

Makefile Targets

• all (default): Builds the Docker image. Equivalent to make docker-build.
• docker-build: Builds the Docker image for the application.
• run: Runs the mygit application inside a Docker container.
  • Use ARGS to pass commands and arguments to mygit. Example: make run ARGS="init"
• docker-run: Alias for run, also builds the image if it doesn't exist.
• clean: Removes the compiled binary (mygit), the local .git and .git_docker_data directories, and the Docker image and container.

Cleaning Up

To remove build artifacts, Docker images, and containers:

make clean
