|

|
|
4499 * previous match or one further.
|
|

|

4501 * Mostly equal to matchcol, except for the first
|
|
|
4502 * match and after skipping an empty match.
|
|

4503 * regmatch.*pos Where the pattern matched in the old text.
|
|
|
4504 * new_start The new text, all that has been produced so
|
|
|
4505 * far.
|
|
|
4506 * new_end The new text, where to append new text.
|
|
|
4507 *
|
|
1499
|
4508 * lnum The line number where we found the start of
|
|
|
4509 * the match. Can be below the line we searched
|
|
|
4510 * when there is a \n before a \zs in the
|
|
|
4511 * pattern.
|

|
|

|

|

4515 * line breaks.

4518 * - When the substitute string contains a line break, the part up
|
|
|
4519 * to the line break is inserted in the text, but the copy of
|
|
|
4520 * the original line is kept. "sub_firstlnum" is adjusted for
|
|
|
4521 * the inserted lines.
|
|
|
4522 * - When the matched pattern contains a line break, the old line
|
|
|
4523 * is taken from the line at the end of the pattern. The lines
|
|
|
4524 * in the match are deleted later, "sub_firstlnum" is adjusted
|
|
|
4525 * accordingly.
|
|
|
4526 *
|
|
|
4527 * The new text is built up in new_start[]. It has some extra
|
|
|
4528 * room to avoid using alloc()/free() too often. new_start_len is
|
|
1389
|
4529 * the length of the allocated memory at new_start.

7
