annotate libinterp/corefcn/input.cc @ 27502:f62f1170ad98

in base_reader, store reference to interpreter instead of lexer * input.h, input.cc (base_reader::m_interpreter): New data member. (base_reader::m_lexer): Delete. (terminal_reader, file_reader, eval_string_reader, input_reader): Change class constructors to accept interpreter object instead of lexer. Change all uses. (base_reader::octave_gets, file_reader::get_input): Access interpreter state using stored reference to interpreter instead of global functions.
