Tal Liron updated ARIA-273:
---------------------------
Description:
It should be easy to wrap various regex engines via an API and make this
configurable to the user. (Specifically to be used for TOSCA constraints.)
The reason this is necessary is that Python's {{re}} is rather quirky and may
not be compatible with other TOSCA implementations. Of course, this is all
OASIS's fault for not specifying the regex language!
For Python especially note there is a [wrapper
library|https://github.com/awahlig/python-pcre] supporting
[PCRE|http://www.pcre.org/], which is likely the most widely used regex. It
might even be worth considering making PCRE the default for ARIA.
