Retrieve the values defined with preprocessor statements in a selection of GLSL tokens
npm install 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!
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:
`` glsl`
#define PI 3.14
#define TAU (PI*2.)
#define VEC vec3(1.)
#define EMPTY
Would yield:
` javascript``
{
PI: '3.14',
TAU: '(PI*2.)',
VEC: 'vec3(1.)',
EMPTY: ''
}
