Question

In the Boost date time library, is there a utility function for converting month short strings (e.g. Jan, Feb, Mar, Apr) to boost::gregorian::greg_month type? The documentation for the library isn’t great and I can’t see anything in the headers.

Answer 1

A hacky work around could be:

#include <iostream>
#include <boost/date_time/gregorian/gregorian.hpp>

int main(void)
{
  auto ptr = boost::gregorian::greg_month::get_month_map_ptr();

  if (ptr)
  {
    auto it = ptr->begin();
    for(; it != ptr->end(); ++it)
    {
      std::cout << it->first << " " << it->second << '\n';
    }
  }
}

This map contains mapping between all the short/long names and the short necessary to create a greg_month instance. Just need to create a little wrapper around it…

per Graeme’s discovery, there is a convenience function which wraps this already boost::date_time::month_str_to_ushort<>
