Mostly, I think you need to use the "recursive decent parser", so you create a
lot of functions like:
HandleClass();
HandleNamespace();
HandleWhile();
With the approach you suggest, is it still possible to parse things like
this?
#ifdef foo
class foo {
#else
class bar {
#endif

Yes, currently, codeblocks' parser can handle this kind of preprocessor
directive. But there are some limitations.
because
#if Const Expression
It need to do Const expression calculation and Macro expansion. Mostly,
it need a Macro symbol table look-up. and note that each translation
unit should have its own symbol table, so this is a time consuming work.
Current way, we just simplified this, if a symbol is not found, we just
set if to "0", so we can always take a conditional preprocessor branch,
although it is not 100% correct branch.
ctags has the same way to handle conditional preprocessor directives.
Global felt quite mature to me the last 10 years I used it. :)

Well, I'd admit that if your code is very complex (contains a lot of c++
template and template partial specialization), It is hard to parse them.
This time, a full compiler front end can solve the issue, but a full
compiler is always running slowly.:-)
Clang compiler has an index feature, but gcc currently doesn't have such
feature.
