zcl User Functions Extension
This zcl extension allows a calling application to support user-defined functions.
Functions are defined via a specific block type, like this:
function "add" {
params = ["a", "b"]
result = a + b
}
The extension is implemented as a pre-processor for cty.Body objects. Given
a body that may contain functions, the DecodeUserFunctions function searches
for blocks that define functions and returns a functions map suitable for
inclusion in a zcl.EvalContext. It also returns a new cty.Body that
contains the remainder of the content from the given body, allowing for
further processing of remaining content.
