-----------------------------------------------------------
[~cos] [~rvs] and others interested in puppet. I dont know what to do here,
need advise.
Well, after some hacking around, i guess puppet core syntax really doesnt
support any way to
- validate x is an array OR
- catch an arbitrary exception with a simple error message
*So* really, the only way to provide any sanity to our users if the components
length is 1, is import {{stdlib}} as a bigtop puppet dependency *or* add a new
custom .pp function of our own.
Should we
1) Add puppet {{stdlib}} to bigtop ? It might enable other cleanup tasks in the
future. We can easily validate strings, cast to arrays and so on w/ stdlib
puppet dependencies. *or*
2) Add a custom function for checking that components is an array ? Advantage
here is no external dep, but yet another 10 lines of code we carry around and
maintain
Im no puppet exper either, so either is neutral for me. Just let me know !
