xlld.wrap.traits

This module implements the compile-time reflection machinery to automatically register all D functions that are eligible in a compile-time define list of modules to be called from Excel.

Import this module from any module from your XLL build and:

import xlld;

mixin(implGetWorksheetFunctionsString!("module1", "module2", "module3"));

All eligible functions in the 3 example modules above will automagically be accessible from Excel (assuming the built XLL is loaded as an add-in).

Members

Aliases

Identity alias Identity(alias T) = T: Undocumented in source.

Enums

Async enum Async: UDA for functions to be executed asynchronously

Functions

dllDefFile DllDefFile dllDefFile(string libName, string description, Flag!"onlyExports" onlyExports): Returns a structure descripting a Windows .def file. This allows the tests to not care about the specific formatting used when writing the information out. This encapsulates all the functions to be exported by the DLL/XLL.
generateDllDef void generateDllDef(string[] args)
getAllWorksheetFunctions WorksheetFunction[] getAllWorksheetFunctions(Flag!"onlyExports" onlyExports): Gets all Excel-callable functions from the given modules
getModuleWorksheetFunctions WorksheetFunction[] getModuleWorksheetFunctions(Flag!"onlyExports" onlyExports): Gets all Excel-callable functions in a given module
getTypeText wstring getTypeText(): Undocumented in source. Be warned that the author may not have intended to support it.
getWorksheetFunction WorksheetFunction getWorksheetFunction(): Take a D function as a compile-time parameter and returns a WorksheetFunction struct with the fields filled in accordingly.
implGetWorksheetFunctionsString string implGetWorksheetFunctionsString(): Implements the getWorksheetFunctions function needed by xlld.sdk.xll in order to register the Excel-callable functions at runtime This used to be a template mixin but even using a string mixin inside fails to actually make it an extern(C) function.
implGetWorksheetFunctionsString string implGetWorksheetFunctionsString(string[] modules): Undocumented in source. Be warned that the author may not have intended to support it.
