Ran Ziv updated ARIA-273:
-------------------------
Priority: Trivial (was: Minor)
> 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: Trivial
>
> 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.
