This adjusts `ternary` to use the same `template.IsTrue` that controls the semantics of the built-in `if` (and friends). For further context, `template.IsTrue` has been officially exported since Go 1.6 (golang/go@a326c3e).

There was a problem hiding this comment.
In my own library, I'd implemented this with a panic for !ok (which I'm happy to adjust this to), but I wasn't sure if panic was appropriate here. 😅

I looked into Sprig today because it implements many functions my own hand-rolled library was, in most cases with the same name/signature! Thank you for creating such a cool project.
One minor difference between my own
ternaryand the one provided by Sprig is that mine acceptsinterface{}instead ofbooland uses the officialtemplate.IsTruefunction that controls the semantics of the built-inif(and friends) to convertinterface{}intobool(for further context,template.IsTruehas been officially exported since Go 1.6: golang/go@a326c3e).Given that this would make
ternarymatch the semantics ofif, it felt like an appropriate change, and it was simple enough that I thought discussing over a concrete PR might be the easiest way to see if this is something that you'd be interested in. 😄Just to be explicit, I'm happy to adjust, rebase, amend, discuss, close, etc! ❤️
