Question

How can I obtain similar functionality with boost

  int idx = md.filepath.lastIndexOf('/');                                 
      md.title = md.filepath.right(md.filepath.length() - idx -1);            
      md.title = md.title.left(md.title.length() - 4);      

Above code( QT based) finds the name of the file without extension , md is an object , filepath, title are QString . I have browsed boost’s string methods like find_last but it returns iterator_range. I m new to boost , thanks in advance .

If all you want to do is filename parsing then you’d be better off using the boost::filesystem::path class. In particular the following methods:

path filename() const;

path stem() const; and

path extension() const;

The class provides conversions to and from std::string and std::wstring.
