code completion with type check

code completion with type check

[Martin]

Hi,

I am programming in C using emacs and some extensions as cc-mode.
Using M-/ (dabbrev-expand) is quite useful, but what I'm really
looking for is a tool that

1. shows me the parameter list when I start a functioncall.
2. gives me a choice for my parameter, e.g. if the parameter's type is
an enum of type test_enum_t (s.below) then I want the extension to
show me that I can pick CHOICE_A and CHOICE_B.
In some C++ or Delphi IDEs this is done by CTRL-Space.
So, there must be something like this out there, right?
I found XRefactory, but it's not free and it only comes up with
feature 1 (if at all).

Martin

typedef enum test_enum {
CHOICE_A = 0,
CHOICE_B = 1
} test_enum_t;

Maybe CEDET/Semantic (http://cedet.sf.net)...

Thanks ...
actually I found semantic a few days ago (I forgot to mention it).
However, semantic does not know about types :(
And I'm having problems getting semantic to only parse a specific set
of directories.
It usually works by diving into a directory structure recursively to
extract tag information.

But if someone has some experience with semantic, I would be gratetful
if someone would share his knowledge/insights.

I'm afraid you won't find the exact thing you're looking for.  CEDET's
Semantic offers some completion mechanisms, but none as integrated and
complete as you see in some IDEs.  `semantic-idle-summary-mode' is
probably your best bet for parameter lists.

I doubt there's anything offering syntactic completions with type checks.


You might find some more stuff at

and

But if you're looking for the IntelliSense fix[0], Emacs is probably not
the best place.
