Martin Atkins	26e820d829	addrs: Don't return zero-length slice in Reference.Remaining. ... Although this rarely matters, making it always be nil when empty makes deep assertions simpler in tests. This also includes a minor update to the test in the core package that first encountered this problem, to improve the quality of its output on failure.	8 years ago
Martin Atkins	4833d2aa79	addrs: helper wrappers for parsing addresses in strings ... Our "Parse..." functions all take hcl.Traversal objects rather than strings, assuming that in most cases we've already parsed a traversal out of some larger construct (usually a config file) before interpreting it as an address. However, there are some situations -- particularly tests -- where being able to easily parse a string directly is helpful. These new "Parse...Str" functions all wrap the function of the same name with no "Str" suffix and first parse the string with the HCL native syntax traversal parser. As noted in the function doc comments, this should not be used in "real" code except in exceptional circumstances, since it creates addresses and diagnostics that do not have useful source location information for reporting diagnostics.	8 years ago
Martin Atkins	63041ffa09	addrs: ParseRef function, for parsing references in expressions ... This function corresponds to terraform.NewInterpolatedVariable, but built with HCL2 primitives. It accepts a hcl.Traversal, which is what is returned from the HCL2 API functions to find which variables are referenced in a given expression.	8 years ago
