Module `Ecaml__.Point`

"Point" is a special buffer position used by many editing commands. Like other positions, point designates a place between two characters (or before the first character, or after the last character), rather than a particular character. The value of point is a number no less than 1, and no greater than the buffer size plus 1.

Each buffer has its own value of point, which is independent of the value of point in other buffers. Each window also has a value of point, which is independent of the value of point in other windows on the same buffer. This is why point can have different values in various windows that display the same buffer. When a buffer appears in only one window, the buffer's point and the window's point normally have the same value, so the distinction is rarely important.

val forward_char_exn : int -> unit: forward_char_exn n moves point n characters forward (backward if n is negative). forward_char_exn raises on reaching end or beginning of buffer. (describe-function 'forward-char).

Precisely, if point is on line i, move to the start of line i + n ("start of line" in the logical order). If there isn’t room, go as far as possible (no error). (describe-function 'forward-line).
