Yes thank you for trying it out. It is nice when a project gets some attention.
Some examples are a bit forgotten that they exist, and then when someone tries
to compile them I get reminded that they should either be fixed to work, or
removed. I decided to leave a comment in there that they are a bit on ice by
now. Everything is still under development and nothing is abandoned, I just
cant do everything at the same time. The most active example at the moment is
the noise_landscape. I recently started to implement portals in there, but they
don't work yet. It's actually quite hard to understand what they are when you
see them in the current state, but they do interesting.
I would be really happy if you try to do something with that project, I made it
so other people can do something with it. But I cannot really recommend using
it as a library. I will make breaking changes when I feel the overall product
will improve on it. If you add another example that does something interesting
though, I might accept your pull request and will maintain it. That is what I
did with the neural network example.
But where do I have regexp code? I can't remember using it.
