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

I happen to skim this thread and had a related question.

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.
