move()

MAYAFLUX_API void MayaFlux::Portal::Text::move	(	EditableText &	s,
		int	n
	)

Move the cursor by n codepoints.

Positive n moves toward the end of the text, negative toward the start. Clamps at whichever text boundary is reached first rather than wrapping or erroring on an out-of-range count.

    if (n > 0) {
        for (int i = 0; i < n && s.cursor < s.text.size(); ++i)
            s.cursor = next_codepoint_offset(s.text, s.cursor);
    } else {
        for (int i = 0; i > n && s.cursor > 0; --i)
            s.cursor = previous_codepoint_offset(s.text, s.cursor);
    }
