Translation of a dynamic regex in awk
 

I am writing a number of dynamic regular expressions. These can get quite complicated.

Is it possible to write an awk function that takes a dynamic regex and prints only what
awk would actually see when interpreting the dynamic regex ?

regexp itself is just a string. You can print it as any other string (if it is stored in a variable). But you cannot print a regex like this:
because it is not stored anywhere.

You are correct, I can print the string. But the string could contain any sort of escape sequences and so on.

What I am looking to do is exclude the complications to have a better and clear idea of what it would match.
