Sorry, I should have looked harder.

I found this:

regex object limitations/behavior for large regexes?

2009-12-30 Thread Aaron Watters
I'm thinking of a design which automatically generates
regex objects which are essentially disjunctions of simple
pattern alternatives.  The number of alternatives might
conceivably run into the thousands or more.

This raises the question: do regex objects behave nicely
when the regex gets very large?  Do they remain as fast?
Do they display reasonable (linear or n log n) memory
growth?  Do they just stop working at some point?

Please reply if you have any experience with very
large regexes or other insights.

Thanks in advance.  -- Aaron Watters
