Capitalize the next char after "Mc" or "Mac"

I hate regex. Well, it hates me. So it seems mutual.

Tried this

Expression: \bMc(\l)
Replace: Mc\U($1)

Tought it would upper all the Scottish names (like McDonalds, McCoy, McScott.....) but it didnt. Probably not even close. Cause I dont know what I do lol.

Anyone know the proper regex for this?

Also, for MacIntosh, LeMans etc. But I can adapt that myself. I think.

You are very close.

FROM:
Mcdonalds, Mccoy, Mcscott.
TO:
McDonalds, McCoy, McScott.

TRY:

1) Regular Expressions: Replace expression "\bMc(.)" with "Mc\U$1" (case sensitive) (skip extension)

Explanations:

\b >> word boundary
Mc >> literal text
. >>> one sign of any character (the symbol is just a dot)
() >> Subexpression, here for to store for later reuse
\U >> Convert all following characters to uppercase.
$1 >> backreference what was matched in subexpression

I take solace in the fact that I have various other skills. Even if my incapability in regex makes me sad.

thanks mate, works perfectly!

So, Macy Gray becomes MacY Gray lol. Do I just add this as an exception (e.g. revert it back to Macy at the end of all actions) or is there a more elegant way to eliminate those - probably rare - instances?

\bMac(.{3,}) >>> for to match "Mac" plus at least 3 of any signs.
In the replacement use then lower case u instead of upper case U.

\u >> Convert only the first character to uppercase.

And in a quiet minute I’ll try to understand how and why it works :-)
