Re: [Boost-users] Template type to constant string

6 Nov 2007

      The solution proposed here is by no means perfect, because if for any reason
I wasn't using RTTI in my application this method wouldn't be acceptable.
However, I suppose I got lucky. I think it would be useful to find a
compile-time alternative to converting a type to a string. The second reason
why the typeid() approach isn't perfect is because it contains the entire
decorated name in the string. In other words, for a class named
"CFooSomeClass" the string returned by typeid( CFooSomeClass).name() is
"class CFooSomeClass" instead of just "CFooSomeClass".

I'm using typeid() as a hack/workaround at the moment until I find something
I'm satisfied with being a permanent solution. I'd appreciate it if you guys
would continue throwing thoughts at this thread so I can check up on it and
maybe get some more ideas.

So far this thread has been a bit off topic in that we've not really
utilized boost at all. Perhaps this is a hint that boost could excel in this
area (assuming it hasn't already)? Maybe there's something boost can do for
me that would help out? I'll review the MPL portion of boost and see what I
can dig up.

Thanks again for everyone's help, I really do appreciate the quick
responses!

Maybe you can try with typeid(t_type).name(), included in
<typeinfo>.
Is this evaluated at compile time ( I thought the OP said something
about
macros )?
No, evaluated at run time
I was looking for template programming ideas and I hit

a case where I needed compile-time type information and I didn't know
offhand how to do it so I gave up ( for some reason a specialization
didn't seem like an easy thing to do).
Does anyone have a good reference link on interesting (portable)
template
programming
approaches ? I found a few things on google but nothing stuck me as
being a complete reference.
Thanks.

Hi,
This is not MS specific. It works with many compilers, and at least
with
gcc
(do not remember the exact version). However, I think "name()" return
value
is not standard and can vary between platforms.

Thanks!
This seems to work, however looking at the implementation of
<typeinfo>
I
...
don't see the keyword "typeid" anywhere. Where in the world is it
coming
from? Is <typeinfo> part of the standard? It's obviously not in STL
since it
lacks the namespace. I'm a little confused as to where the file
comes
from,
as I've never heard of it before. I'm guessing it is a microsoft
specific
thing.
Let me know. Thanks again.

Hi,
As you know, with Microsoft VS preprocessor operators you can
convert
...
...
a type passed in to a macro to a string. For example:
#define TO_STRING( type ) #type
I would like to do the same thing with a template type:
template< typename t_type >
void TO_STRING()
{
  // Do something here with t_type to make it a string and then
return
it
}
Is there something in boost that can facilitate the behavior I'm
describing? Thanks.
