octave: libinterp/parse-tree/pt-stmt.cc annotate

annotate libinterp/parse-tree/pt-stmt.cc @ 23723:ab8831d346c1

revamp echo command and move related variables inside tree_evaluator class * pt-stmt.h, pt-stmt.cc (tree_statement::echo_code): New argument, prefix. Pass prefix to tree_print_code constructor instead of VPS4. * basics.txi: Delete documentation for echo_executing_commands. * interpreter.h, interpreter.cc (interpreter::maximum_braindamage): Now a member function. (interpreter::interpreter): Call tree_evaluator::echo directly instead of using Fecho_executing_commands. Don't force input to be echoed if forced_interactive is etst. * input.h, input.cc (Fecho_executing_commands): Delete. (Vecho_executing_commands): Delete variable and all uses. (VPS4): Delete. (set_default_prompts): Don't set global value for PS4 here. (base_reader::do_input_echo): Delete. (gnu_readline): Don't call do_input_echo. * pt-eval.h, pt-eval.cc (Fecho_executing_commands): Delete. (FPS4): Move here from input.cc. (Fecho): Move here from input.cc Rewrite. Handle "echo function on|off" syntax. (echo_state): Move enum declaration to tree_evaluator class from input.h. * ov-usr-fcn.cc (octave_user_script::call, octave_user_function::call): Push echo state before executing commands. Don't print function header or trailer here. (octave_user_function::print_code_function_header, octave_user_function::print_code_function_trailer): New arg, prefix. Pass prefix to tree_print_code constructor instead of VPS4. * pt-eval.h, pt-eval.cc (tree_evaluator::m_PS4, tree_evaluator::m_echo, tree_evaluator::m_echo_state, tree_evaluator::m_echo_file_name, tree_evaluator::m_echo_file_pos, tree_evaluator::m_echo_files): New member variables. (tree_evaluator::echo_state, tree_evaluator::PS4, tree_evaluator::echo, tree_evaluator::push_echo_state, tree_evaluator::set_echo_state, tree_evaluator::set_echo_file_name, tree_evaluator::set_echo_file_pos, tree_evaluator::echo_this_file, tree_evaluator::echo_code): New member functions. (tree_evaluator::visit_break_command, tree_evaluator::visit_continue_command, tree_evaluator::visit_decl_command, tree_evaluator::visit_simple_for_command, tree_evaluator::visit_complex_for_command, tree_evaluator::visit_if_command, tree_evaluator::visit_no_op_command, tree_evaluator::visit_return_command, tree_evaluator::visit_switch_command, tree_evaluator::visit_try_catch_command, tree_evaluator::visit_unwind_protect_command, tree_evaluator::visit_while_command, tree_evaluator::visit_do_until_command): Manage echo_file_pos and echo code here.
