annotate libinterp/parse-tree/parse.h @ 17693:efbe746f8fa8

eliminate octave_comment_buffer singleton * lex.h (octave_base_lexer::comment_buffer): New class adapted from octave_comment_buffer class. No longer a singleton class. (octave_base_lexer::comment_buffer::reset): New function. (octave_base_lexer::reset): Call comment_buf.reset. (octave_base_lexer::comment_buf): New data member. (octave_base_lexer::get_comment): New function. * comment-list.h, comment-list.cc (octave_comment_buffer): Delete. Change all uses of octave_comment_buffer to use local comment_buf object instead. * parse.h (octave_base_parser::make_statement): New member function. * oct-parse.in.yy (make_statement): Delete. Change all uses of make_statement to use the member function instead. (safe_fclose): Don't extract and delete comment list here.
