Introduction

Purple is a simple compiled language. Right now it supports:

• Compilation into x86, MIPS
• Basic arithmetic parsing with precedence
• Comparisons
• Variable declaration and assignment
• If, Else statements
• While Loops

Examples

Purple uses C-style syntax, although this may change as the compiler is built

{
    int bob;
    int alice;
 
    bob = 5;
    alice = 10;
 
    print bob + alice; // 15
    print bob > alice; // 0
 
    int bob_alice;
    bob_alice = 10 + 10 + bob + alice; // 35
    if(bob_alice > 30){
        print bob_alice;
    }
 
    int i;
    i = 0;
    while (i < 20) {
        print i;
        i = i + 1;
    }
}
