IupControlsOpen and others, are not necessary. When using Lua the Iup initialization functions, IupOpen, Iuplua_open function is declared in the header file iuplua. You must call the initialization functions manually. There are IUP dynamic libraries with names that will conflict with the names usedĪdditionally you can statically link the IupLua libraries, but The simplest form require" iup" and so on, can not be used because Or you can set it in Lua before loading iup modules: package.cpath = package.cpath. If you are using another Lua distribution you can use the environment: export LUA_CPATH=./\?.so\. Includes these modifications on the default search path. Must also contains at least the following:Īlso compatible with Lua 5.2 and 5.3, just replace the "51" suffix by "52" You can use require" iuplua" and so on, but the LUA_CPATH Lua 5.1 "require" can be used for all the IupLua It has support for all the additional controls, for IM,Īvailable at the Download. The distribution files include an executable called iuplua51, that you can Today IupLua completely replaces the LED functionality and adds much more.> Still using LED, its support will continue in IUP. Lua was created after LED, so that's why LED Parameters and attributes: IupButton("test") > iup.button endĬonstructors were changed so you can use tables to initialize their
IupSetCallback(button, "ACTION", button_action_cb) > function button:action(). Title = IupGetAttribute(label, "TITLE") > title = label.title In Iup additional features were created for the Lua Binding using the metamethods.Īttributes and callbacks can be set and get in a much more natural way: IupSetAttribute(label, "TITLE", "test") > label.title = "test" (names are in lower case) Manually call iup.Destroy or elem: destroy, if In Lua all parameters are checked and a Lua error is emitted when the check fails.Īll the objects are NOT garbage collected by the Lua garbage collector, you must In which enumeration flags are combined with the bitwise operator OR, in Lua the flags are added arithmetically. Parameters that would have their values modified are now returned by the function in the same order. Metatables have the "tostring" metamethod implemented to helpĪlso the functions which receive values by reference in C were modified. Under the table "iup" using the following name rules: iupXxx -> iup.Xxx (for functions) The functions and definitions will be available General application will do require"iuplua", and require"iupluaxxxx" to all other All the IUP functions are available in Lua, with a few exceptions.
