⁠Free Pascal Compiler

If you have legacy Pascal code or want to explore computer history, check out Free Pascal⁠. Developed in the 70s and 80s, this language was traditionally taught as a first programming language in many university courses during the 80s and 90s. Free Pascal is a mature, versatile, open-source compiler for Pascal and Object Pascal.

⁠Launching

Prepare your Pascal code. For example, here's a simple "Hello, World!" program:

program helloWorld(output);
begin
	writeLn('Hello, World!')
end.

Let's create a pas_code/ directory to hold a Pascal project. Save the code above in a file named pas_code/helloworld.pas.

1. Create a container with pas_code/ mapped to /home/devf:

   docker pull 200ms/fpc_devf
   docker run -it -v pas_code:/home/devf 200ms/fpc_devf bash
   

   Copy
2. Inside the container, compile your code:

   fpc helloworld.pas
   

   Copy
3. Run the compiled program:

   ./helloworld
   

   Copy

Enjoy and have fun exploring Pascal!
