Compression converts else if to elseif

[micahjon]

H, I noticed that compressing this shader code:

    }else
    if (mode == 1.0){ // GROW

        offsetStrength *= 0.25;

Results in the following string:

}elseif(mode==1.0){offsetStrength*=0.25;

Where else if is converted to elseif

I'm guessing this is unintentional. My understanding is that elseif is not valid syntax for GLSL, or at least not widely supported. I realize having else if on separate lines is also strange, but I'm working with a large legacy codebase and figured compression shouldn't impact the output, as long as the input is valid.

Thanks for looking into this!

I'm also having this problem but with else blocks with no {}. Consider the following code:

// Copied from ThreeJS
float getFace( vec3 direction ) {
	vec3 absDirection = abs( direction );
	float face = - 1.0;
	if ( absDirection.x > absDirection.z ) {
		if ( absDirection.x > absDirection.y )
			face = direction.x > 0.0 ? 0.0 : 3.0;
		else
			face = direction.y > 0.0 ? 1.0 : 4.0;
	} else {
		if ( absDirection.z > absDirection.y )
			face = direction.z > 0.0 ? 2.0 : 5.0;
		else
			face = direction.y > 0.0 ? 1.0 : 4.0;
	}
	return face;
}

The else blocks get compressed into the contained statement resulting in elseface. Adding {} around the block is a good work around for me, but the compression should not break the code.

@vwochnik , just submitted a PR that should fix this issue. Thanks for considering!
