OWCSTL string missing C++98 features

[adamyg]

Hi, the following C++98 elements are missing from the current <string> / <_strdef.h> implementation:

Iterator interfaces:

template <class InputIterator>
string  (InputIterator first, InputIterator last);

template <class InputIterator>
string& assign (InputIterator first, InputIterator last);

Compare Methods:

int compare (const string& str) const;
int compare (size_t pos, size_t len, const string& str) const; 
int compare (size_t pos, size_t len, const string& str, size_t subpos, size_t sublen) const;
int compare (const char* s) const;
int compare (size_t pos, size_t len, const char* s) const;
int compare (size_t pos, size_t len, const char* s, size_t n) const;

For greater portability the following C++11 features could also be added:

const_iterator cbegin() const /*noexcept*/;
const_iterator cend() const /*noexcept*/ ;

const_reverse_iterator crbegin() const /*noexcept*/ ;
const_reverse_iterator crend() const /*noexcept*/;

char& front();
const char& front() const;
void pop_back();
void shrink_to_fit()

not sure how far it has progressed since i last checked, but open watcoms c++ compiler was pretty barebones and did not have full support for C++98. To get better support the C++ compiler needs an update unfortunatly the project only has one devoted C++ maintainer. Im sure any help is appeciated non the less :).

Thanks for your report. As @revelator mentioned, support for even C++98 is incomplete throughout the library. There is (very slow) work toward remedying that situation, and it is ongoing. I will mark this issue as a library enhancement.

I copied the list of missing members to the Wiki for reference. The Wiki is the place where we are accumulating information on which library components still need to be implemented.

Was wondering how much of the missing elements could be taken from an older boost version?

1.64.0, an example supported MSVC-2002 which wasn't C+03

It would be more fun just to write them. :)

Indeed build verses buy; the following was only a test.

//
//  Demonstrate boost/array, OpenWatcom
//

#if defined(__WATCOMC__)
#define _MSC_VER 1310  //Visual Studio .NET 2003
#endif
#include <boost/array> //boost_1_33_1
#if defined(__WATCOMC__)
#undef _MSC_VER
#endif
#include <iostream>

int
main()
{
    boost::array<int, 5> numbers = {1, 2, 3, 4, 5};

    std::cout << "The elements are: ";
    for (boost::array<int,5>::const_iterator it = numbers.begin(), end = numbers.end(); it != end; ++it) {
        std::cout << *it << " ";
    }
    std::cout << "\n";
}

//end
