Very concrete regexp question (TouchOSC related)

[toscanini]

Hello,
I have gone through ShelLusers excellent regexp tutorials but some aspects still remain unclear, namely routing issues. Most concretely I'd need to get the forelast element from /3/multitoggle3/6/1

All concrete help (and also a bit of extra theory around routing) most welcome!

Trial and error but I am getting there

[regexp (.*)/(.*)/(.*)]

...and outputting from backreferences...

[toscanini]

Ok there is still a problem left, what TouchOSC sends to [udpreceive] has either 3 or 4 elements. (by "elements" I mean the data between the slashes, for example /3/multitoggle3/6/1). I haven't found the solution yet that works both ways.
Something like [regexp /(.*)/(.*)/(.*)/?(.*)?] but better...

Replacing slash by space will produce a list for any number of elements.

[regexp / @substitute " "]

Lovely. I wouldn't claim I understand why, but it works!
No, wait! I actually do
thank you broc!

[regexp / @substitute " "]

AKA: the only regexp I actually use. Like, ever. Makes OSC parsing ever so easy.

Alternatively one can just use OSC-route, but I typically prefer not to.
