Replace character in capture group

I can’t get any of the syntaxes listed … Replacement Expression

@Alan-Kilborn said in Replace character in capture group:

You are correct.

And you weren’t the first person this week to not notice that the \g and \k syntaxes are in the search section, and not in the replacement section (which tried to be explicit that any syntax not mentioned in the replacement section was not valid in the replacement field, but has apparently failed).

Could you both look at the proposed capture groups and backreferences phrasing and substitution phrasing , and make sure that the updated sections makes the distinction more clear?

repl: abc_$+{Name}_xyz
your examples show you were trying to use \g which I believe only works in the find expression.

Aha! Looks that’s true in NPP — though \g<Name> actually DOES work in PCRE replacement expressions at Regex101.

Thanks for the education.

DO NOT rely on regex101 for the more esoteric aspects of regex. Doing so, and then intending to use the results in Notepad++ will cause frustration. Sure, okay, for simple cases, but the caliber of stuff you have been discussing in this thread is going to be different in N++ and regex101.

Looks good to me so far, though coming from a fairly green regex user like me, I’d take that with a grain of salt. :-)

On a tangent here, I’ve noticed, on occasion when doing find/replace operations, that the In selection checkbox was sometimes ghosted (not available to check or uncheck), which I keep meaning to compile a list of circumstances for presentation and inquiry in these forums sometime. I notice that in both official and proposed versions of the doc, there seems to be no mention of any limitations on when the In selection checkbox is available. There seem to be some known limitations (at least one of which is mentioned here). Maybe they should be added to the docs?

I think I’ve already made it fairly clear, in my previous posts to this thread, that that’s what I’m finding to be the case.

Perhaps, but I get the feeling you might be holding on to regex101 a bit much. :-)

Plus, I’m kind of a late joiner to this thread; there’s a lot of content.

In selection checkbox enabled condition: A single selection of one or more characters, that is NOT a column block selection.

Note that the checkbox’s appearance status can only be relied upon when you actually switch input focus to the find (family) window – upon activation the code runs a check to make sure you have the proper type of selection, and updates the checkbox and its state at that time.

Thanks. Submitted PR #127. Hopefully, it will make it in before the next release of the npp-user-manual.org website.

Looked fine to me as well.
Thanks for your fine attention to the manual.
I just need to read it more when I have trouble with things. :-)

Hello, @peterjones,

Sorry, I’ve just seen your post where you asked people to verify the N++ official documentation ! I’ll try to have a look, myself, very soon. It would be better to do it before the next release of the website !

But, as I said to Alan, at the moment, my TO DO list, concerning N++ or else, is getting much longer ;-))

Cheers,
