Glint’s for Loops

Let’s get loopy!

Ranged For

for <identifier> in <container> <body>;

This form of the for loop mimics C++’s ranged for loops. It’s purpose is to easily loop over built-in containers like dynamic arrays and views.

In effect, it binds <identifier> to a reference to each element within <container>.

Emits code in the form of: NOTE: Should we cache <container> expression, or evaluate it multiple times?

cfor
  {
    iter :: <container>.data;
    end :: <container>.data[<container>.size];
  };
  iter != end;
  iter [= 1;
  {
    <identifier> :: @iter;
    <body>;
  };

C For

for <initialiser>; <condition>; <increment>; <body>;

This form of the for loop mimics a C for loop exactly.

Emits code in the form of:

{
  <initialiser>;
  while <condition> {
    <body>;
    <increment>;
  };
};
