Hi,
I have a situation where I would like to parse the command line options not as (int argc, char **argv)
template<typename charT> basic_parsed_options< charT > parse_command_line(int argc, const charT *const argv, const options_description &, int style = 0, function1< std::pair< std::string, std::string >, const std::string & > ext = ext_parser());
but as a std::string.
The std::string is the equivalent of the command line but obtain either from reading some file or cut and paste.
E.g. my input string would be something like "myprog 817382 --lod="lod.cfg" --radius=3.0"
With such string as the above, I'd like to know how I should pass it to boost::program_options
Hi Nicolas, I am afraid you'd have to tokenize this string according to the rules you want. For windows, there's parse_winmain function that does that, but for Linux, there's no such function because: - On Linux, program entry point always has array of chars - Implementing tokenization for linux might be even trickier than for windows.
