Define Documentation

#define SH_BEGIN_PROGRAM (  target   )

Begin a new program block. Nesting programs is not allowed. Return values: ShProgram  A reference to the new program. See also: SH_END_PROGRAM Definition at line 53 of file ShSyntax.hpp. Referenced by SH::access(), SH::cast(), SH::connect(), SH::dup(), SH::fillcast(), SH::keep(), SH::lerp(), SH::lose(), SH::namedConnect(), SH::operator<<(), SH::renameInput(), SH::renameOutput(), and SH::transform().

#define SH_BREAK

Break out of a loop, terminating the loop. See also: SH_CONTINUE SH_WHILE SH_DO SH_FOR Definition at line 149 of file ShSyntax.hpp.

#define SH_CONTINUE

Break out of a loop, continuing with the next iteration. See also: SH_BREAK SH_WHILE SH_DO SH_FOR Definition at line 157 of file ShSyntax.hpp.

#define SH_DECL (  var   )

Declare variable with the same name as var. Usage: Sh_Some_Type SH_DECL(var); or Sh_Some_TYPE SH_DECL(var) = initial_value; See also: SH_NAMEDDECL Definition at line 179 of file ShSyntax.hpp. Referenced by SH::lerp().

#define SH_DO

Indicate the start of a do-until statement. See also: SH_UNTIL Definition at line 112 of file ShSyntax.hpp.

#define SH_ELSE

Indicate the start of the else-block of an if statement. See also: SH_IF SH_ENDIF Definition at line 83 of file ShSyntax.hpp.

#define SH_END_PROGRAM

End the current program definition. If there is a backend and the program has a specified target (e.g. vertex or fragment), this will also compile the program. See also: SH_BEGIN_PROGRAM Definition at line 62 of file ShSyntax.hpp. Referenced by SH::connect(), SH::dup(), SH::keep(), SH::lose(), and SH::operator<<().

#define SH_ENDFOR

Indicate the end of a for statement. See also: SH_FOR Definition at line 137 of file ShSyntax.hpp.

#define SH_ENDIF

Indicate the end of an if-statement. See also: SH_IF SH_ELSE Definition at line 89 of file ShSyntax.hpp.

#define SH_ENDWHILE

Indicate the end of a while-statement. See also: SH_WHILE Definition at line 103 of file ShSyntax.hpp.

#define SH_FOR (  init, cond, update   )

Begin a for statement. The semantics are mostly the same as for C++ for statements, but unlike in C++ declaring variables in init part is not allowed. See also: SH_ENDFOR Definition at line 129 of file ShSyntax.hpp.

#define SH_IF (  cond   )

Begin an if statement. See also: SH_ELSE SH_ENDIF Definition at line 77 of file ShSyntax.hpp.

#define SH_NAME (  var   )

Set the name of a variable to be its C++ name. See also: SH_DECL SH_NAMEDECL Definition at line 168 of file ShSyntax.hpp.

#define SH_NAMEDECL (  var, varName   )

Declare variable with the given name Usage: Sh_Some_Type SH_NAMEDECL(var, "name"); or Sh_Some_Type SH_NAMEDECL(var, "name") = initial_value;. See also: SH_DECL Definition at line 189 of file ShSyntax.hpp. Referenced by SH::access(), SH::cast(), SH::dup(), SH::fillcast(), SH::keep(), SH::lerp(), SH::lose(), and SH::transform().

#define SH_UNTIL (  cond   )

End a do-until statement, iterating as long as cond is satisfied. See also: SH_DO Definition at line 117 of file ShSyntax.hpp.

#define SH_WHILE (  cond   )

Begin a while statement, iterating as long as cond is satisfied. See also: SH_ENDWHILE Definition at line 98 of file ShSyntax.hpp.
