please consider following testcase:
$ cat t.cpp
#include <set>
#include <string>
template < typename T, typename S = std::set< std::string >, int N = 1 >
struct X
{
virtual ~X() = 0;
};
void f()
{
X< float > x; // error here.
}
in the standard way g++ reports all template arguments
in diagnostics messages.
$ g++ t.cpp -Wall -c
t.cpp: In function 'void f()':
t.cpp:10: error: cannot declare variable 'x' to be of abstract type 'X<float,
std::set<std::string, std::less<std::string>, std::allocator<std::string> >,
1>'
t.cpp:5: note: because the following virtual functions are pure within
'X<float, std::set<std::string, std::less<std::string>,
std::allocator<std::string> >, 1>':
t.cpp:6: note: X<T, S, N>::~X() [with T = float, S = std::set<std::string,
std::less<std::string>, std::allocator<std::string> >, int N = 1]
it hurts my eyes to read this.
tons of expanded arguments in boost/stlport diagnostics aren't so funny ;)
it would nice to see a magic -Whuman-readable;) option to enable more
human readable reporting, e.g.:
t.cpp: In function 'void f()':
t.cpp:10: error: cannot declare variable 'x' to be of abstract
type 'X<float, [defaults]>'
t.cpp:5: note: because the following virtual functions are pure
within 'X<float, [defaults]>':
t.cpp:6: note: X<T, S, N>::~X() [with T = float, [defaults]]
is it possible to implement this in easy way?
