Snake using ANSI Escape Sequences

ANSI (American National Standards Institute) escape sequences allow control of the terminal just by printing specific strings. Unfortunately not all terminals support all features, so things like colors may appear differently on different terminals. I made this for Linux based systems with Docker and a Windows 10 host OS (using command prompt and Cmder).

Credit to sd9 for sections pertaining to changing the behavior of the standard input stream.

Installation and Compilation Instructions:

0. Clone this repository and nagivate into the folder

(navitage to an appropriate location first)
git clone https://github.com/calvincramer/snake_console.git snake
cd snake

1. Have developement environment

If you have linux environment, skip to last step to compile and run. Also easy to do on WSL. The next steps use are for a docker environment.

2. Get the ubuntu base image:

docker pull ubuntu

3. Create image from Dockerfile

docker build -t snake_image .

4. Create container with mounted folder

Without gdb:

docker create --name=snake -it -v <path_to_snake_folder>:/snake snake_image /bin/bash

With gdb support:

docker create --cap-add=SYS_PTRACE --security-opt seccomp=unconfined --name=snake -it -v <path_to_snake_folder>:/snake snake_image /bin/bash

Note that your mounted folder will be different. I did mine with a Windows host machine which is probably different than Linux. Also note you can mount multiple volumes just by adding more -v arguments.

For example, my -v <path_to_snake_folder>:/snake looked like this:

-v //c/Users/CalvinLaptop/CalvinLaptop_Files/snake:/snake

5. Start container and attach to container

docker start snake && docker attach snake

6. Compile

cd /snake

make
./snake

or

make D=1
gdb snake
use gdb to your heart's content

• note: compile with debug if you get a out of bounds compilation error.
