A wrapper for win32-api that simplifies and automates common idioms
== Description This is a wrapper for Win32::API that simplifies various idioms typically used by people who use Win32::API. == Synopsis require 'windows/api' include Windows # Defaults to 'V' prototype, 'L' return type and 'kernel32' library GetVersion = API.new('GetVersion') # Defaults to 'L' return type and 'kernel32' library CloseHandle = API.new('CloseHandle', 'L') # Defaults to 'kernel32' library GetWindowsDirectory = API.new('GetWindowsDirectory', 'LI', 'I') # Explicitly state every argument GetComputerNameEx = API.new('GetComputerNameEx', 'PPP', 'I', 'kernel32') # Use long data type names GetUserName = API.new('GetUserName',['LPTSTR','LPDWORD'],'BOOL','advapi32') # Attributes for possible inspection puts GetVersion.dll_name # 'kernel32' puts GetVersion.function_name # 'GetVersion' puts GetVersion.prototype # ['V'] puts GetVersion.return_type # 'L' # Automatic method generation # This code.... module Windows module Foo API.auto_namespace = 'Windows::Foo' API.auto_constant = true API.auto_method = true API.auto_unicode = true API.new('GetComputerName', 'PP', 'B') end end # Is the same as this code... module Windows module Foo GetComputerName = Win32API.new('kernel32', 'GetComputerName', 'PP', 'I') GetComputerNameA = Win32API.new('kernel32', 'GetComputerNameA', 'PP', 'I') GetComputerNameW = Win32API.new('kernel32', 'GetComputerNameW', 'PP', 'I') def GetComputerName(p1, p2) GetComputerName.call(p1, p2) != 0 end def GetComputerNameA(p1, p2) GetComputerName.call(p1, p2) != 0 end def GetComputerNameW(p1, p2) GetComputerName.call(p1, p2) != 0 end end end == Advantages over plain Win32::API * Automatic constant generation. * Automatic definition of ANSI and Unicode method wrappers, including special handling for boolean methods. * Ability to use more familiar Windows data types, e.g. DWORD. * Automatic handling of msvcrt vs msvcrXX via MSVCRT_DLL constant. == Other Stuff There's also a WideString class for easily creating wide strings for Ruby 1.8.x. Ruby 1.9.x can use Ruby's encoding methods to accomplish the same effect, however. == More documentation See the RDoc documentation, which should have been automatically generated if you installed this as a gem. == Future Plans This library will eventually be dropped in favor of FFI once I'm convinced that FFI is stable for both mingw and mswin. == Bugs None that I'm aware of.
