Private Methods

Method	Description
CommentLinesWith ( string _Source, string _Pattern ) : string	Comments any line containing the specified pattern
ConvertConstantBuffers ( string _Source ) : string	Converts all constant buffers syntax (cbuffer) into a struct with a cbuffer attribute Builds a dictionary of constant names so we can replace their simple use by a composition cbufferName.ConstantName instead
ConvertFloatToDouble ( string _Source ) : string	Converts the float type to double type
ConvertOutFunctions ( string _Source ) : string	Converts all functions with an "inout" syntax as "ref" and fix callers of such functions to issue either a "ref" or an "out" prefix
ConvertRegisters ( string _Source ) : string	Converts all registers syntax (: register(xx)) into an attribute inserted above the line with register
ConvertSemantics ( string _Source ) : string	Converts all semantics syntax (: NAME) into an attribute inserted above the line with semantic
ConvertVectorConstructors ( string _Source ) : string	Converts vector constructors (float2, float3, float4, uint2, uint3, uint4, etc.) by a function that calls actual C# constructors
EnsureAlphanumeric ( string _Name ) : bool	Ensures the provided name is alphanumeric
ErrorIfLinesWith ( string _Source, string _Pattern ) : void	Throws an exception if there is a line with the //#if syntax, which is not supported in C# (except very annoying //#define at the very beginning of the file)!
FindBOL ( string _Source, int _StartIndex ) : int	/// Inserts a snippet of text at a specific index in the source /// Finds the index of the beginning of the current line
FindEOL ( string _Source, int _StartIndex ) : int	Finds teh index of the end of the current line
IndexOfBetween ( string _Source, string _Pattern, int _StartIndex, int _EndIndex ) : int	Same as IndexOf except it returns -1 if the match is outside of the specified [Start,End] range
IsCommentedLine ( string _Source, int _Index ) : bool	Checks if the current position is part of a comment (warning: only // coments are supported!)
MakeStructFieldsPublic ( string _Source ) : string	Makes all the fields in structs public
ResolveIncludes ( FileInfo _ShaderPath, string _ShaderSource ) : string	Resolves all include files an merge them into the shader source
