CIE Pseudo-Code Compiler

This is a pseudo-code compiler for the CIE IGCSE and AS&A Levels Computer Science course. It is designed to be used with 0478/9718/9708.

I am using the official CIE pseudo-code specification as a reference for this compiler. You can find the specification here.

Small rant

WHY IS IT CALLED PSEUDOCODE IF IT CAN BE COMPILED? IT'S NOT PSEUDOCODE IF IT CAN BE COMPILED. IT'S A REAL PROGRAMMING LANGUAGE. IT'S NOT PSEUDO.

How does it work?

The compiler is not exactly a compiler, I am using ply (Python Lex-Yacc) to parse the pseudo-code and convert it to an abstract syntax tree (AST). I then use the AST to generate C++ code, and call g++ to compile the generated C++ code.

How to use

1. Write your pseudo-code in a file (e.g. code.psc)
2. Run the compiler with the file as an argument (e.g. python main.py code.psc)
3. The generated C++ code will be in temp/temp.cpp
4. The compiled binary will be in temp/temp(.exe)
5. If the -r flag is used, the compiled binary will be run

Requirements

• Python 3
• gcc (for compiling the generated C++ code)

Usage

$ python main.py -h
usage: main.py [-h] [-o OUTPUT] [-c CFILE] [-r] [-d] file

positional arguments:
  file                  The file to compile

options:
  -h, --help            show this help message and exit
  -o OUTPUT, --output OUTPUT
                        The output file
  -c CFILE, --cfile CFILE
                        The C file to generate
  -r, --run             Run the compiled file
  -d, --debug           Debug output
