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

annotate libinterp/parse-tree/parse.h @ 28407:808e3964987b stable

accept multi-line interactive input (bug #58370) * lex.h, lex.ll (base_lexer::input_buffer::m_pos): Delete. Use offset from beginning of buffer instead. (base_lexer::input_buffer::m_offset): New data member. (base_lexer::input_buffer::copy_chunk): New argument, BY_LINES. Perform line buffering on input if BY_LINES is true. (push_lexer::fill_flex_buffer): Call copy_chunk with BY_LINES = true. * parse.h, oct-parse.yy (base_parser::statement_list): Append new statements to existing m_stmt_list. (base_parser::run (const std::string&, bool)): Also continue parsing input if lexer input buffer is not empty.
