whynot | And for _why day

Dealing with processing large matrices (NxM with 1K <= N <= 20K & 10K <= M <= 200K), I often need to pass Numpy matrices to C++ through Cython to get the job done and this works as expected & without copying.

However, there are times when I need to initiate and preprocess a matrix in C++ and pass it to Numpy (Python 3.6). Let's assume the matrices are linearized (so the size is N*M and it's a 1D matrix - col/row major doesn't matter here). Following the information in here: exposing C-computed arrays in Python without data copies & modifying it for C++ compatibility, I'm able to pass C++ array.

The problem is if I want to use std vector instead of initiating array, I'd get Segmentation fault. For example, considering the following files:

fast.h

I am trying to build a regex that captures successfully the following bolded text:

background-image: url( https://domain/adress/with/other/stuff?alsoaquerystring=whynot );

Expected output is:

https://domain/adress/with/other/stuff?alsoaquerystring=whynot

And this is what I have tried so far, but I can't manage to say "capture everything that's inside here, no matter what characters it has got".
