OK, you probably don't even need to be an expert - just better than me!

I want to detect if an expression includes "Keyboard 2" (without the quotes) - the K can be capitalized or not. "Keyboard 2" may appear at the beginning, middle or end of my expression.

rename your post as follows:

So I've tried [regexp "K|keyboard 2"] , and that gets me a "keyboard 2" out the substring outlet when I give it an expression that contains "keyboard 2" - so far so good. But then it inappropriately matches a "K" substring for any expression that includes a K....

"K|keyboard 2" - will do a or'ed match of either K and keyboard 2

"[Kk]eyboard 2" - matches a character class (group of characters between []), then the rest of the search (eyboard 2)

Oh man! My Max5 license is still on my old laptop and I can't afford Max6 on this machine yet so I haven't been around much. Sorry if you feel I've been neglecting you Dan! ;)

i saved every successful use of regexp + i collect these examples from any regexp thread appearing here since i don't know, a year or two. all in a big patch. this is already helping me so much when i'm stucked again with regexp. because in most cases one example comes at least close to what i want to do. this might be a good tool release one day after they have been categorised a little bit.

There are many online (general) regex test pages out there, a good one is

Whilst not specific to max, its handy non the less.

Also, you could dive into the Perl regex tutorial, which would help quite a bit

There'll be more in there than is possible with the max regex object, but it's all good stuff

Wow, gskinner is very nice, thanks for that tip big_pause!

OK - follow up to my original question in this thread: now I want to detect when there is a "Keyboard" 

 a "2" in a symbol. But unlike my previous question, the 2 may not necessarily appear right after the Keyboard; it might appear before, or several words after the Keyboard. How to do with regexp?

[regexp "[Kk]eyboard.*2|2.*[Kk]eyboard"]


Thank you again! So that *almost* works - it doesn't however match something like "Trackpad/Keyboard 2", which it should. So I changed your suggestion to [regexp .*[Kk]eyboard.*2|2.*[Kk]eyboard] and it seems to work...

The thing I wasn't familiar with is the "." - does that mean any character or space? I know that the following "*" means "zero or more occurrences of the preceding character."

The .dot. means anything but a line break, which you shouldn't have to worry about in this case so your example should work just fine.

you shouldn't need that .* that you've added

Calling all regexp experts!
