I'm thinking of writing something that will accept a series of example texts and work out the common elements in order to build suitable Regular Expression(s) that will match all the examples.

Not identified a need for it, but it sounds like a fun thing to do. :)

So yeah, does anyone know of any tools that already do this? (Especially Open Source ones, so I can look at their code).

You have a strange concept of 'fun'.

I think he uses the word "fun" like we use the word "interesting".

:S How do you use the word interesting?

Something that stimulates my mind and makes me want to learn more.

 

Programming is interesting.

 

Rollercoasters are fun.

Oh, well I think we use both words the same way then. :D

I'd have to argue that anything you choose to pursue out of interest would have to be in some way, to you, fun. Fun in a specific (and kind of sad) way, admittedly, but I'd say fun nonetheless.

I dunno, I tend to think of "fun" as something that makes you happy but that also has an element of excitement to it.

I find some coding exciting :-$
