unki	214009e0f3	fix yamldecode()-example, missing a file() call	6 years ago
Martin Atkins	02576988c1	lang: "try" and "can" functions ... These are intended to make it easier to work with arbitrary data structures whose shape might not be known statically, such as the result of jsondecode(...) or yamldecode(...) of data from a separate system. For example, in an object value which has attributes that may or may not be set we can concisely provide a fallback value to use when the attribute isn't set: try(local.example.foo, "fallback-foo") Using a "try to evaluate" model rather than explicit testing fits better with the usual programming model of the Terraform language where values are normally automatically converted to the necessary type where possible: the given expression is subject to all of the same normal type conversions, which avoids inadvertently creating a more restrictive evaluation model as might happen if this were handled using checks like a hypothetical isobject(...) function, etc.	6 years ago
