v1.3.0

• convert: There are now conversions from map types to object types, as long as the given map type's element type is convertible to all of the object type's attribute types. (#42)
• function/stdlib: HashiCorp has contributed a number of additional functions to the standard library that were originally implemented directly inside their Terraform codebase: (#37)
  • Element: take an element from a list or tuple by index, using modulo wrap-around.
  • CoalesceList: return the first non-empty list argument.
  • Compact: take a list of strings and return a new list of strings with all empty strings removed.
  • Contains: returns true if a given value appears as an element in a list, tuple, or set.
  • Distinct: filters duplicate elements from a list while retaining the order of remaining items.
  • ChunkList: turn a list into a list-of-lists where each top-level list is a "chunk" of a particular size of elements from the input.
  • Flatten: given a sequence that might contain other sequences, eliminate any intermediate sequences to produce a flat sequence.
  • Keys: return a list of keys from a map or object value in lexical order.
  • Values: return a list of values from a map in the same order as Keys.
  • Lookup: conditional lookup of an element from a map if it's present, or a fallback value if not. (This one differs from its Terraform equivalent in that the default value argument is required.)
  • Merge: given one or more maps or objects, merge them together into a single collection.
  • ReverseList: given a list, return a new list with the same items in the opposite order.
  • SetProduct: compute the cartesian product of one or more sets.
  • Slice: extract a consecutive sub-list from a list.
  • Zipmap: given a pair of lists of the same length, interpret the first as keys and the second as corresponding values to produce a map.
  • A factory MakeToFunc to build functions that each convert to a particular type constraint.
  • TimeAdd: add a duration to a timestamp to produce a new timestamp.
  • Ceil and Floor: round a fractional value to the nearest integer, away from or towards zero respectively.
  • Log: computes a logarithm in a given base.
  • Pow: implements exponentiation.
  • ParseInt: parses a string containing digits in a particular base to produce a whole number value.
  • Join: concatenates the elements of a list of strings with a given separator to produce a string.
  • Split: partitions a string by a given separator, returning a list of strings.
  • Sort: sorts a list of strings into lexical order.
  • Chomp: removes one or more newline characters from the end of a given string, producing a new string.
  • Indent: prepends a number of spaces to all lines except the first in a given string, producing a new string.
  • Title: converts a string to "title case".
  • TrimSpace: trims spaces from the start and end of a given string.
  • Trim: generalization of TrimSpace that allows user-specified trimming characters.
  • TrimPrefix: like Trim but only at the start of the string.
  • TrimSuffix: like Trim but only at the end of the string.
