7 | 5192 * copycol Column in the old text where we started |
5193 * looking for a match; from here old text still | |
5194 * needs to be copied to the new text. | |
5195 * matchcol Column number of the old text where to look | |
5196 * for the next match. It's just after the | |
5197 * previous match or one further. | |
5198 * prev_matchcol Column just after the previous match (if any). | |
5199 * Mostly equal to matchcol, except for the first | |
5200 * match and after skipping an empty match. | |
5201 * regmatch.*pos Where the pattern matched in the old text. | |
5202 * new_start The new text, all that has been produced so | |
5203 * far. | |
5204 * new_end The new text, where to append new text. | |
5205 * | |
1499 | 5206 * lnum The line number where we found the start of |
5207 * the match. Can be below the line we searched | |
5208 * when there is a \n before a \zs in the | |
5209 * pattern. | |
7 | 5210 * sub_firstlnum The line number in the buffer where to look |
5211 * for a match. Can be different from "lnum" | |
5212 * when the pattern or substitute string contains | |
5213 * line breaks. | |
5214 * | |
5215 * Special situations: | |
5216 * - When the substitute string contains a line break, the part up | |
5217 * to the line break is inserted in the text, but the copy of | |
5218 * the original line is kept. "sub_firstlnum" is adjusted for | |
5219 * the inserted lines. | |
5220 * - When the matched pattern contains a line break, the old line | |
5221 * is taken from the line at the end of the pattern. The lines | |
5222 * in the match are deleted later, "sub_firstlnum" is adjusted | |
5223 * accordingly. | |
5224 * | |
5225 * The new text is built up in new_start[]. It has some extra | |
5226 * room to avoid using alloc()/free() too often. new_start_len is | |
1389 | 5227 * the length of the allocated memory at new_start. |
7 | 5228 * |
5229 * Make a copy of the old line, so it won't be taken away when | |
5230 * updating the screen or handling a multi-line match. The "old_" | |
5231 * pointers point into this copy. | |
