A simple python interpreter implemented by yacc and lex and it is capable of interpreting python-like languages simply.

We leads the language of the translation the analysis the method to produce the language rule.

This project is mainly contributed by Ke Rui and Jiawei Wang

Directory Structure

• src : All the important code of Python_Interpreter
  • .y : productions/rewriting mle and syntax-directed file
  • .l : code of lexical analysis and identify specific text strings to generate TOKEN
  • .cpp : functions implemented by c++
  • .h : the head file
  • Makefile : make all files
• assets : some pictures and others

Running

Make sure you get all the requestments, if not, do below

sudo apt-get install flex bison

Clone the repository from the github page

git clone git@github.com:Berkesole/Tiny_Python_Interpreter.git

You have two ways to make all the file

lex minipy-lab.l
yacc --defines=minipy-lab.tab.h minipy-lab.y

Then you should make the .cpp file, and maybe you should ignore some Warning Messages

c++ -g -o analysis y.tab.c minipy.cpp
/* Anyway, you can also use `make` to make all the files */
make
