D Sharp | Weston Gorczyca

D Sharp is an interpreted programming language with the these math operations:

() ^ * / + -

Here is an example scriptexample script:

a = 1 + 2 + 3;
b = 1 * 2 * 3;
print(a);
print(b);
c = a * b;
print(c);

Here is another one:

hello = 6 + 4; y = 7 * 9;
print(hello + y);
print(y);

In order to run this script, it goes through three stages: tokenization, parsing, and interpretation.

tokenizer:

a = 1 + 2 + 3 -> [VARIABLE(a), EQUALS, NUMBER(1), PLUS, NUMBER(2), PLUS, NUMBER(3)]

parser:

[VARIABLE(a), EQUALS, NUMBER(1), PLUS, NUMBER(2), PLUS, NUMBER(3)] 
->
PROGRAM
  ASSIGNMENT
    VARIABLE(a)
    EXPRESSION
      OPERATION(PLUS)
        OPERATION(PLUS)
          NUMBER(1)
          NUMBER(2)
        NUMBER(3)

interpreter:

sets a to { 1 + 2 + 3 }
evaluates { 1 + 2 + 3 } to 6
