Position of the insert cursor on the current input line.

Definition at line 183 of file cli.c.

u8 unix_cli_file_t::cursor_direction

The current direction of cursor travel.

This is important since when advancing left-to-right, at the right hand edge of the console the terminal typically defers wrapping the cursor to the next line until a character is actually displayed. This messes up our heuristic for whether to use ANSI to return the cursor to the end of the line and instead we have to nudge the cursor to the next line. A Value of 0 means we're advancing left-to-right; 1 means the opposite.
