@ -80,6 +80,11 @@ The supported built-in functions are:
|
|||
* `base64encode(string)` - Returns a base64-encoded representation of the
|
||||
given string.
|
||||
|
||||
* `compact(list)` - Removes empty string elements from a list. This can be
|
||||
useful in some cases, for example when passing joined lists as module
|
||||
variables or when parsing module outputs.
|
||||
Example: `compact(module.my_asg.load_balancer_names)`
|
||||
|
||||
* `concat(list1, list2)` - Combines two or more lists into a single list.
|
||||
Example: `concat(aws_instance.db.*.tags.Name, aws_instance.web.*.tags.Name)`
