| 38 * This file contains various searching-related routines. These fall into | |
| 39 * three groups: | |
| 40 * 1. string searches (for /, ?, n, and N) | |
| 41 * 2. character searches within a single line (for f, F, t, T, etc) | |
| 42 * 3. "other" kinds of searches like the '%' command, and 'word' searches. | |

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