The expressions it generates work, but they are much more complex than the equivalent hand-crafted expression. Note that text2re uses a template-based, modularized and very generalized approach to regular expression generation.

I dare to say there is no automatic regex generator that gets it right without user intervention, since this would require the machine knowing what you want. I don't think this is available in source code, though. There is text2re, a free web-based "regex by example" generator.
