octave-lyh: libinterp/parse-tree/parse.h annotate

annotate libinterp/parse-tree/parse.h @ 16139:2fd39ab12209

move a function and data member from lexical_feedback to octave_parser * parse.h: Include lex.h. * parse.h, oct-parse.yy (octave_parser::reset): New function. (octave_parser::end_of_input): New data member. (octave_parser::octave_parser): Initialize it. * lex.h, lex.ll (lexical_feedback::reset): Rename from reset_parser. (lexical_feedback::parser_end_of_input): Delete. * input.cc (get_debug_input): Call octave_parser::reset, not lexical_feedback::reset_parser. * toplev.cc (main_loop): Likewise. * oct-parse.yy (eval_string, parse_fcn_file): Likewise. * toplev.cc (main_loop): Set octave_parser::end_of_input, not lexical_feedback::parser_end_of_input. * oct-parse.yy: Use octave_parser::end_of_input, not lexical_feedback::parser_end_of_input.
