glsl-token-defines

Retrieve the values defined with preprocessor statements in a selection of GLSL tokens.

Doesn't handle full function-style macros for the time being. Patches welcome!

Usage

defs = defines(tokens)

Where tokens is an array of tokens produced by glsl-tokenizer.

Returns an dictionary object where keys are the name of the defined variable, and values are the values of the defined variable. If a variable is not assigned a value, this will be an empty string.

For example, the following:

#define PI 3.14
#define TAU (PI*2.)
#define VEC vec3(1.)
#define EMPTY

Would yield:

{
  PI: '3.14',
  TAU: '(PI*2.)',
  VEC: 'vec3(1.)',
  EMPTY: ''
}
