4962 * needs to be copied to the new text. | |
4963 * matchcol Column number of the old text where to look | |
4964 * for the next match. It's just after the | |
4965 * previous match or one further. | |
4966 * prev_matchcol Column just after the previous match (if any). | |
4967 * Mostly equal to matchcol, except for the first | |
4968 * match and after skipping an empty match. | |
4969 * regmatch.*pos Where the pattern matched in the old text. | |
4970 * new_start The new text, all that has been produced so | |
4971 * far. | |
4972 * new_end The new text, where to append new text. | |
4973 * | |
1499 | 4974 * lnum The line number where we found the start of |
4975 * the match. Can be below the line we searched | |
4976 * when there is a \n before a \zs in the | |
4977 * pattern. | |
7 | 4978 * sub_firstlnum The line number in the buffer where to look |
4979 * for a match. Can be different from "lnum" | |
4980 * when the pattern or substitute string contains | |
4981 * line breaks. | |
4982 * | |
4983 * Special situations: | |
4984 * - When the substitute string contains a line break, the part up | |
4985 * to the line break is inserted in the text, but the copy of | |
4986 * the original line is kept. "sub_firstlnum" is adjusted for | |
4987 * the inserted lines. | |
4988 * - When the matched pattern contains a line break, the old line | |
4989 * is taken from the line at the end of the pattern. The lines | |
4990 * in the match are deleted later, "sub_firstlnum" is adjusted | |
4991 * accordingly. | |
4992 * | |
4993 * The new text is built up in new_start[]. It has some extra | |
4994 * room to avoid using alloc()/free() too often. new_start_len is | |
1389 | 4995 * the length of the allocated memory at new_start. |
7 | 4996 * |
4997 * Make a copy of the old line, so it won't be taken away when | |
