ParaCL

Description

Hello everyone! Here you will find my implementation of the lexer and parser of the ParaCL (Para = "Paralympics", C = "C", L = "Language") programming language, which is currently C-like.

The project is written in C++ using the following generators: Flex for the lexer, Bison for the parser, which is different from my first fully handwritten Scielang language.

Opportunities

The language supports

• standard arithmetic and logical operations;

a = 2;
c = a + b;
c = a - b;
c = a * b;
c = a / b;

c = a == b;
c = a != b;
c = a > b;
c = a < b;
c = a >= b;
c = a <= b;

c = (a == 2 && b == 3);
c = (a == 1 || b == 4);

c = -(a+10);

• if/else expressions;

a = 1;
b = -4;
if (a == 0)
    a = b + 5;
else
    a = b;

• while loops;

a = 4;
while (a != 0)
{
    a = a - 1;
}

• input and output functions

a = ?;
print a;

Added the ability to handle syntactic (and a few semantic) errors.

Future updates

Support for functions.
