I didn't know that not placing a replacement character can slow it down. I'll keep that in the memory bank for the next time I use it.

Same.  Kudos for the tip!

It count the replacements out of the box.

Note that I replace with a character (any character will do). If you don't wire the replacement, the string will be shrunk for every replacement, slowing things down.

I guess it gets more complicated if you add "sometimes 'y'".

Yes, but not by much:

Since the entire match is a capturing group (the first) we can replace the match with itself (indicated by "$1").

But "y" is only a vowel (in the US) under certain conditions.

Ah, didn't know that.

That would make a funky regex.

But if there is one online, it will work.

Here's a discussion about vowels vs consonants regex's, but I don't think that covers it all: Regex - matching world which contain only vowels or consonants - Stack Overflow

I never thought of that.  Someone, somewhere probably made a regex for that!

OMG here's what ChatGPT came up with:

[aeiouAEIOUYy](?<![aeiouAEIOUy])[aeiouAEIOU]*$|(?<=[aeiouAEIOYy])y(?![aeiouAEIOUy])

Explanation:

• [aeiouAEIOUYy] matches any vowel, including 'y' in both lowercase and uppercase.
• (?<![aeiouAEIOUy])[aeiouAEIOU]*$ matches a vowel (excluding 'y') that is at the end of a word or syllable. The (?<![aeiouAEIOUy]) is a negative lookbehind that ensures there's no vowel or 'y' before the vowel we're matching.
• (?<=[aeiouAEIOYy])y(?![aeiouAEIOUy]) matches 'y' that is surrounded by vowels (including 'y') in the middle of a syllable. The (?<=[aeiouAEIOYy]) is a positive lookbehind that ensures there's a vowel or 'y' before the 'y', and the (?![aeiouAEIOUy]) is a negative lookahead that ensures there's no vowel or 'y' after the 'y'.

At a glance, it looks like it will check a word for vowels.

It doesn't seem to check vowels in a text. Or at least I don't see anything related to word barriers.

The rules I gave it related to a single word.  I forgot about that.
