glslify-hex

A transform stream for glslify that replaces CSS-style hexadecimal colors with vec3/vec4 definitions.

Usage

Once you've enabled the stream, you simply put your hex colors in your file like so:

void main() {
  gl_FragColor = vec4(#ff0000, 1.0);
}

The above color will be (naïvely) replaced with a GLSL vec3 definition, i.e.:

void main() {
  gl_FragColor = vec4(vec3(1.0, 0.0, 0.0), 1.0);
}

You can also use 8-digit hexadecimals for vec4 definitions. The above example could also be expressed like so:

void main() {
  gl_FragColor = #ff0000ff;
}

To use glslify transform streams, you currently need to use glslify-stream directly:

var createStream = requrire('glslify-stream')
 
var stream = createStream('./shader.vert', {
  transform: ['glslify-hex']
})
 
stream.pipe(process.stdout)

This might have changed by the time you read this though, so be sure to double check the glslify documentation!
