Idea: adding recasting/renaming for assignments with structure members

[saidelike]

One idea that may not be hard to implement since what HexraysPyTools does is already more complicated would be to add support for recasting/renaming simple assignments:

So something similar to https://github.com/igogo-x86/HexRaysPyTools#recasting-shiftr-shiftl-renaming-shiftn-ctrlshiftn but for assignments

So the idea is if we have, with PVOID v1, and struct1 { int arg1};:

v1 = (PVOID)struct1->arg1;

When we click on v1 and hit SHIFT+L it would change the type of v1 to int:

v1 = struct1->arg1;

Then we hit SHIFT+N and it would rename v1 to arg1:

arg1 = struct1->arg1;

We just need to support appending an underscore to the name until the rename succeeds as the name may already exist, so it could generate something like:

arg1___ = struct1->arg1;

We could also imagine supporting the other direction (i.e. renaming the right part based on the left part but I think the initial idea is more useful.

What do you think?

Re-reading the linked part, it is actually already supported for simple assignments, but not for structure members

Another example would be this function call:

  result = Func1(
             whatever,
             struct2->InputBuffer,
             struct2->OutputBuffer,
             struct2->OutputBufferLength,
             &struct2->total_size);

and the prototype of Func1:

int __stdcall Func1(WHATEVER*whatever, _BYTE *a2, void *a3, unsigned int a4, _DWORD *a5)

It would be nice if we could name a2 = InputBuffer, a3 = OutputBuffer, a4 = OutputBufferLength and a5 = total_size just by using the recasting/renaming shortcuts.

Yeah that's good ideas, there're more minor facilities like this can be added. I hope to get around to implementing it
