Thanks for weighing in. What I’m trying to do is a somewhat complicated regex find/replace on a file roughly represented as such:

[1st line containing data to be used in replacement elsewhere]
[…]
[2nd line containing data to be used in replacement elsewhere]
[…]
[3rd line containing data to be used in replacement elsewhere]
[…]
[1st line where replacement will take place]
[…]
[2nd line where replacement will take place]
[…]
[3rd line where replacement will take place]
[…]

Each instance of […] is one or more lines of other data.

Starting at the beginning of the file, my FIND pattern will match from [1st line containing data to be used in replacement elsewhere] all the way through [1st line where replacement will take place], then insert data retrieved from the former into the latter, and also deleting all lines from start of file up to but not including [2nd line containing data to be used in replacement elsewhere] in the same process. I was hoping it would be simple to have it go on finding/replacing for all the remaining corresponding line pairs if I could make it use Wrap around and Replace All— though perhaps it wouldn’t, since some of the data within the target match areas will have changed between quasi-iterations — but guess I’ll concede defeat and make a loop. Thanks again!

There are two ways of looking at “wrap around”

1. If you really mean, “I want to search the whole document, regardless of where my caret is right now.” That can easily be implemented using the startPosition=0 argument. (I believe that’s what effectively happens when you do a regular expression replacement in the N++ Replace dialog using Replace All)
2. If you really mean, “I want to search the whole document, starting where I am right now and going until the end.” For that in PythonScript, if p is the current caret location, then do it with two calls to the editor.rereplace() or similar function: the first with startPosition=p and endPosition as the length of the file (or without it supplied, that’s what it will default to); and then a second with startPosition=0 and endPosition=p (… which is what Alan posted just as I was typing the last clause)

No, if you want it to “wrap around”, you’d have to do two calls to editor.research(). The first one should search caret position to end-of-file position, then the second one should search position 0 to the original caret position.

Note that in Notepad++ searches with “wrap around” enabled, it also does this; there is no native support in Scintilla for it.
