A compiler and interpreter for the minimal programming language PL/0 written in C++.

The parser uses the grammar from Wikipedia

The compiler targets a custom instruction set. Therefore the project also builds an assembler and vm to execute the generated code.

To compile the code yourself, execute the following steps:

1. Navigate to the projects root
2. Create a new folder (e.g. Debug) with mkdir Debug && cd Debug
3. Within this folder, issue the command cmake .. -DCMAKE_BUILD_TYPE=Release
4. Now you have to decide which target to build
   • pl0: this only builds the interpreter
   • pl0c: this builds the compiler, assembler and vm
   • compile_and_run_example: this is a handy target, if you want to execute the generated asm code directly. This target assumes you have a file called example.pl0 in the projects root. To use another file set the cmake variabel EXAMPLE_FILE to the filepath you want to use
5. Now you can run all build executables located in the ./bin folder
6. All executables take a file as their first command line argument. Image you have a hello.pl0 file, then you would invoke the compiler, interpreter, assembler, or vm with <executable> hello
