Suppose, I have written reusable module in fasm.
This module requires some imports (kernel, user and so on).

Then I want to include this module in my main program module.
Can I declare imports required for reusable module in that reusable module and include them in the main program?
Or I can only declare all of the imports from all modules in the main program?

Is the following code legal:

Code:

library user32,'USER32.DLL'
library user32_module1,'USER32.DLL'

import user32, \
        DefWindowProc,'DefWindowProcA'

import user32_module1, \
        CreateWindowEx,'CreateWindowExA', \
        GetMessage,'GetMessageA'

[/code]

you can develop set of macros, which will collect list of imports. There were such macros some time ago, but they were very slow.

In my opinon, declaring imports once per project is not that much pain to make such solutions for it.

also note that when external symbols are declared only in main file, your module is even more reusuable. For example you can compile it to object, and then link with libraries.

1. And what about reusable projects? (Which can not be compiled into the library due to some reasons).

2. What if my main file does not use some of the functions implemented in the project? Will they be included in object module?

For example, I implemented framework for developing ActiveX control (like ATL). To create control it is ehough to type

Code:

stdcall CreateObject, \
    0, \
    sizeof.CMyControl, \
    CControlImpl_InterfaceMap, \
    CControlImpl_TableMap

But it requires also declaration of all imports used by whole framework. So using library modules in fasm requires A LOT OF TYPING. I think it is wrong.

what do you mean by "reusuable project"?

Depending on way you chose to use the module. If you are speaking about linking object - yes, they everything be present. If you link library (more object files compiled to single file), then only object files actually used will be present.
