Compiler of a Simple Imperative Language

Developed as part of a Formal Languages and Translation Techniques course at Wrocław University of Science and Technology (winter 2020/2021).

Technologies

Created using:

• Python 3.8.5
• SLY 0.4

How to use

In the main directory run

python3 compiler.py <input file> <output file>

Files

• specs.pdf – project guidelines including the grammar of the compiled langugage and the assembly commands available in the virtual machine (in Polish),
• compiler.py – the lexer and the parser,
• symbol_table.py – memory management and the symbol table,
• code_generator.py – generation of the output assembly code from the syntax tree.

The tests_* directories contain some examples that allow to test the output code. Most of them were written by Maciej Gębala and Karol Gotfryd. They can be conveniently run with

./test.sh <directory name>

Error handling tests can be run using

./test_errors.sh

Both scripts require a pre-compiled virtual machine executable in the main project directory. The machine was developed by the lecturer, Maciej Gębala. Its sources can be found inside the virtual_machine directory. In order for all tests to run correctly, build it with the CLN library installed.

The misc directory contains some simple scripts that helped me during the development process.
