namespace boost { namespace program_options { namespace detail { /** Standalone parser for config files in ini-line format. The parser is a model of single-pass lvalue iterator, and default constructor creates past-the-end-iterator. The typical usage is: config_file_iterator i(is, ... set of options ...), e; for(; i !=e; ++i) { *i; } Syntax conventions: - config file can not contain positional options - '#' is comment character: it is ignored together with the rest of the line. - variable assignments are in the form name '=' value. spaces around '=' are trimmed. - Section names are given in brackets. The actual option name is constructed by combining current section name and specified option name, with dot between. If section_name already contains dot at the end, new dot is not inserted. For example: @verbatim [gui.accessibility] visual_bell=yes @endverbatim will result in option "gui.accessibility.visual_bell" with value "yes" been returned. TODO: maybe, we should just accept a pointer to options_description class. */ class common_config_file_iterator : public eof_iterator
