I am looking at that since right now something like this:
-var-create - * "(anonymous namespace)::foobar"
will not work since c_parse doesn't know anything about '(anonymous
namespace)'. I guess it wouldn't be too hard to hack around this
particular case, but a proper solution would be preferable.
I wonder what the right thing to do on a statement like that is. The
problem with anonymous namespaces is that we call them all "(anonymous
namespace)", but they're many different namespaces, one for each file
with anonymous namespaces. In that file, you would access the type
as just "foobar". Maybe we should give each anonymous namespace
a different name.
However, in the case I am talking about, it is known which anonymous namespace
is relevant since we have the frame, so really the only thing that is missing is
to recognize that '(anonymous namespace)' could, effectively, be removed from
the type name and then using the 'bare' var name crawl up the blocks to find the
matching visible var in the given context. But I am not 100% sure the solution
ok. So we could, perhaps, use it if c_parse fails and the language is c++?
Anyway, cp-name-parser.y isn't a replacement for c-exp.y. It's a name
parser; it accepts both names and types in cases where we don't know
which are which, and it does not support any expressions except when
they can appear inside a template argument. Once you've identified
something as a symbol name then you might hand it off to this parser
to find the canonical form of the name, before searching the symbol
In the example above 'foobar' is a variable defined in the anon. namespace, and
'FooBar' is class name, and my last comment is not precise; IDE uses the
variable name correctly but I am not familiar with internals on what does it do
to build that name. In any case, the '(anonymous namespace)' part comes from gdb.
The issue is evident when using IDE (CDT). IDE will call
which prints type (correctly) something like this: '(anonymous
namespace)::FooBar' and then IDE uses this string as argument to
-var-create, but unfortunately, this doesn't work.
(Why are you creating a varobj for a type, anyway?)
