The embedded regex tester for creating new log reading is working fine.

What would be great is an additional field where you get the json_encoded version of the regex.
I was in need to write a small php script for getting/testing it.

By using the own small script, I identified that it makes a huge difference in using the regex entered in the tester and a json_encoded version of it. The pure regex can do fine while the jsoned version can make troubles, especially when you deal with single/double quotes.

Therefore a tester running both, pure regex and jsoned regex would be also very helpful
