31 * This file contains various searching-related routines. These fall into | |
32 * three groups: | |
33 * 1. string searches (for /, ?, n, and N) | |
34 * 2. character searches within a single line (for f, F, t, T, etc) | |

40 * | |
41 * The string search functions are divided into two levels: | |
42 * lowest: searchit(); uses an pos_T for starting position and found match. | |
43 * Highest: do_search(); uses curwin->w_cursor; calls searchit(). | |
44 * | |
45 * The last search pattern is remembered for repeating the same search. | |
46 * This pattern is shared between the :g, :s, ? and / commands. | |
47 * This is in search_regcomp(). | |
48 * | |
49 * The actual string matching is done using a heavily modified version of | |
50 * Henry Spencer's regular expression library. See regexp.c. | |
