ExtensionBehavior

enum Wizt::Programmable::ShaderPrefix::ExtensionBehavior

https://www.khronos.org/opengl/wiki/Core_Language_(GLSL)#Extensions

Enumerator
enable	Causes the named extension to work; if the implementation does not support the extension, it only gives a warning. Fails if used with all.
require	Causes the named extension to work; if the implementation does not support the extension, it fails. It also fails if used with all.
warn	Causes the named extension to work; however, using the extension will emit warnings. If used with all, then the use of any extensions will emit warnings.
disable	Prevents the named extension from working at all. Thus, any use of it will be seen as undefined syntax and cause an error. If used with all, then this prevents any extensions from working.

fillSources()

bool Wizt::Programmable::ShaderPrefix::fillSources

(

std::vector< std::string > &

Sources

)

const

Fill the first elements of the given Sources with the shader prefixes as computed from the current prefix settings.

Returns

false if there size of the Sources vector is smaller than getNumberOfSources().

setExtensionBehavior()

void Wizt::Programmable::ShaderPrefix::setExtensionBehavior	(	const glsl &	Ext,
		const ExtensionBehavior	E = enable
	)

Generates a string of the kind.

#extension Extension : enable

and places it into the extensions list.
