My open course on Compilers, Grammars and Programming Languages

This repository contains the code I wrote for my self-inflicted class about Compilers https://pgrandinetti.github.io/compilers/.

Use it at your risks.

As side project for a MOOC on Compilers I built a new (basic) programming language. Turing-complete, but without supports for many things.

This repo contains the Grammar's specifications, as well as the compiler for this new language, written in C and organized in 4 modules:

• Lexical Analysis
• Parsing
• Semantic Analysis
• Code Generation

1. Compile my Compiler! You'll need a C compiler, e.g. gcc main.c cgen.c parser.c lexer.c
2. Write your program in my language and place it in a text file. An example is offered in the repo with the file code.e.
3. Now compile your program with ./a.out ./code.e.

The result is a Python executable script, by default ./out.py. You can optionally run ./a.out ./code.e /home/user/result.py, to specify the path for the output file.

• Why generated code is in Python?
• What is my language?
• How does the Compiler work?
