Command line input handling TLC
I didn't manage to usefully split this further into smaller independent pieces, so: - Use "struct buffer" more. - Split out the responsibility of composing a complete command line from multiple input lines split with backslash ( E.g.: (gdb) print \ 1 + \ 2 $1 = 3 (gdb) ) to a separate function. Note we don't need the separate readline_input_state and more_to_come globals at all. They were just obfuscating the logic. - Factor out the tricky mostly duplicated code in command_line_handler and command_line_input. gdb/ChangeLog 2016-03-09 Pedro Alves <palves@redhat.com> * event-top.c (more_to_come): Delete. (struct readline_input_state): Delete. (readline_input_state): Delete. (get_command_line_buffer): New function. (command_handler): Update comments. Don't handle NULL commands here. Do not execute commented lines. (command_line_append_input_line): New function. (handle_line_of_input): New function, partly based on command_line_handler and command_line_input. (command_line_handler): Rewrite. * event-top.h (command_handler): New declaration. (command_loop): Defer command execution to command_handler. (command_line_input): Update comments. Simplify, using struct buffer and handle_line_of_input. * top.h (struct buffer): New forward declaration. (handle_line_of_input): New declaration.
