39 * This file contains various searching-related routines. These fall into | |
40 * three groups: | |
41 * 1. string searches (for /, ?, n, and N) | |
42 * 2. character searches within a single line (for f, F, t, T, etc) | |
43 * 3. "other" kinds of searches like the '%' command, and 'word' searches. | |

46 /* | |
47 * String searches | |
48 * | |
49 * The string search functions are divided into two levels: | |
50 * lowest: searchit(); uses an pos_T for starting position and found match. | |
51 * Highest: do_search(); uses curwin->w_cursor; calls searchit(). | |
52 * | |
53 * The last search pattern is remembered for repeating the same search. | |
54 * This pattern is shared between the :g, :s, ? and / commands. | |
55 * This is in search_regcomp(). | |
56 * | |
57 * The actual string matching is done using a heavily modified version of | |
58 * Henry Spencer's regular expression library. See regexp.c. | |
