Tal Liron created ARIA-273:
------------------------------
Summary: Allow user to choose among multiple regex engines for
TOSCA constraints
Key: ARIA-273
URL: https://issues.apache.org/jira/browse/ARIA-273
Project: AriaTosca
Issue Type: Story
Reporter: Tal Liron
Priority: Minor
It should be easy to wrap various RE 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.
