Fat 16 Interpreter

A interpreter for Fat 16 images.

Usage

You can run it with xmake or with docker.

To run with xmake:

xmake && xmake r interpreter <path-to-img>

To run with docker:

• Build the image and create the container with the script (this will open container after create)

./scripts/create_container

• To run the app, you can use the script:

./scripts/run <path-to-img>

• To delete the image and the container after usage, you can run:

./scripts/delete_container

• To use another image, you have 3 options:
  1. Move the image to the assets folder before create the docker image;
  2. Copy the object from the local machine to the assets folder and re-build the project with the following command:

  # in the local machine
  docker cp <path-to-img-in-local-machine> matozinho_fat16:/home/cppdev/assets

  # in the container
  xmake build -a

  3. Copy the image directly to the folder with the executable

  # in the local machine
  docker cp <path-to-img-in-local-machine> matozinho_fat16:/home/cppdev/build/linux/x86_64/release/assets

Useful commands for docker

# if the container is stopped, start and connect to it
docker start matozinho_fat16 && docker attach matozinho_fat16

# list all running containers
docker ps

Interpreter

The interpreter starts on the root dir of the image, and you can use the command help to see all available commands.
