Hi Markus,
The preprocessor constructs do not have a body in the sense
of IASTNodes, they can intersect with ast-nodes at
arbitrary points. Very often this is not the case, however
we have to deal with those cases as well.
CDT cannot
provide you with code completion in inactive code.
You can figure out a reasonable settting for the macros
used in your preprocessor conditionals and configure your
project accordingly. You can also have different settings
associated with different build configurations and switch back and forth between
them.
There is some limited support to get AST for inactive code.
Please consult the java-doc of ITranslationUnit.AST_PARSE_INACTIVE_CODE for
that.
Markus.
Hi
together,
my
name is Markus and I am currently working at a solution which can find the
elements inside of a preprocessor #if() body.
Here
a small sample what I mean:
void foo(void){
#if(x) {
int a;
}
#else ......
}
With this part of code in the code completion list of the cdt
editor the element "a" isn't listed. Important to know is that the element "x"
has in my scope of the project no value. So it isn't possible for the
parser/preprocessor to know if the _expression_ is true or false and will add
the elements of the #else part to the ast. As I can get all preprocessor
statements from the IASTTranslationUnit I think there should be a way to
acquire also the body of such preprocessor #if statements with unknown
_expression_ result, isn't it. And that is the point for my idea. If I can get
out the preprocessor #if body of the cdt everything would be
fine. Is
there a possibility to get this skiped part?
Thanks
in advance for all your support!!!!
Cheers,
Markus
