| 29 * This file contains various searching-related routines. These fall into | |
| 30 * three groups: | |
| 31 * 1. string searches (for /, ?, n, and N) | |
| 32 * 2. character searches within a single line (for f, F, t, T, etc) | |
| 33 * 3. "other" kinds of searches like the '%' command, and 'word' searches. | |

| 35 | |
| 36 /* | |
| 37 * String searches | |
| 38 * | |
| 39 * The string search functions are divided into two levels: | |
| 40 * lowest: searchit(); uses an pos_T for starting position and found match. | |
| 41 * Highest: do_search(); uses curwin->w_cursor; calls searchit(). | |
| 42 * | |
| 43 * The last search pattern is remembered for repeating the same search. | |
| 44 * This pattern is shared between the :g, :s, ? and / commands. | |
| 45 * This is in search_regcomp(). | |
| 46 * | |
| 47 * The actual string matching is done using a heavily modified version of | |
| 48 * Henry Spencer's regular expression library. See regexp.c. | |
| 49 */ | |

| 52 * Two search patterns are remembered: One for the :substitute command and | |
| 53 * one for other searches. last_idx points to the one that was used the last | |
| 54 * time. | |
