EVALUATE ARITHMETIC EXPRESSIONS PROJECT

In this small project, I'm implementing a parser that will parse arithmetic expressions and evaluate them!

This is a part of my bigger project which is the DJOLANG which will be a programming language made for educational purposes!

EXPLANATION

You'll find in the src directory the files needed for the implementation of this parser!

string_viewf.pas : contains the implementation of the string view data structure needed in lexing the user input!

lexerf.pas : contains the lex function which will take the user input and return a sequence of tokens needed for parsing!

parserf.pas : contains the functions nedded for parsing user input and generating the abstract syntax tree!

astf.pas : contains the constructors of the AST nodes!

Getting Started

Follow these instructions to compile and run the programs:

Prerequisites

• FREE PASCAL COMPILER: Make sure you have fpc installed to compile the PASCAL programs.

Compilation

To compile the programs, use the following commands in your terminal:

$ cd bin
$ ./make.sh

Usage

EXECTUING

After compiling, run the programs as follows:

$ ./run.sh
