<div dir="ltr"><div><div>My point is that quoting problem do exists probably but it exists even without YAQL being used anywhere.<br></div>For example consider Mistral workbook containing value: { get_attr: [my_instance, first_address] }. get_attr in Mistral may have nothing to to with Heat's get_attr and even if it is it may be just a HOT snippet that cannot be evaluated at the moment. For example it may be part of a HOT template embedded into Mistral workbook and Mistral workflow is going to create another Heat stack using that template. Now if you embed such workbook into HOT template (and thus get HOT embedded into Mistral embedded into HOT :) ) you need to make sure that Heat's parser is not going to try to parse that workbook but treats it like a black box. This is regardless of YAQL being even exist.

</span>So far nobody has stepped up to defend me, so I'll accept that maybe<br>
people do think it is crazy. What I'm really confused by is why we have<br>
a new weird ugly language like YAQL (sorry, it, like JQ, is hideous),<br>
and that would somehow be less crazy than a well known mature language<br>
that has always been meant for embedding such as javascript.<br>
<br>
Anyway, I'd prefer YAQL over trying to get the intrinsic functions in<br>
HOT just right. Users will want to do things we don't expect. I say, let<br>
them, or large sections of the users will simply move on to something<br>
else.<br>
