Overview

Abstract Extension base class. Extensions allow modular additions of custom directives, AST transformations, and validation rules without modifying core compiler files.

Defined in:

crshader/extensions/extension.cr

Instance Method Summary

#handle_directive(directive_name : String, call : Crystal::Call, parser : DslParser) : Bool
Custom top-level directives (e.g.
#name : String
#transform_program(program : ShaderProgram) : Nil
AST transformation pass executed before semantic validation and code generation.
#validate(program : ShaderProgram, context : Validator::ValidationContext) : Nil
Custom semantic validation rules executed during Validator::SemanticValidator pass.

abstract def name : String #

def transform_program(program : ShaderProgram) : Nil #

def validate(program : ShaderProgram, context : Validator::ValidationContext) : Nil #
