|
|
|
|
Retrieve the values defined with preprocessor statements in a selection of
|
|
[GLSL tokens](http://github.com/stackgl/glsl-tokenizer).
|
|
|
|
Doesn't handle full function-style macros for the time being. Patches welcome!
|
|
|
|
## Usage
|
|
|
|
[](https://nodei.co/npm/glsl-token-defines/)
|
|
|
|
### `defs = defines(tokens)`
|
|
|
|
Where `tokens` is an array of tokens produced by
|
|
[glsl-tokenizer](http://github.com/stackgl/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: ''
|
|
}
|
|
```
