Re: return() errors inside iteration functions
Henrik Lindberg I'm sorry, I'm not sure that I'm parsing this sentence accurately.
If called from within a lambda the return will return from the function containing the lambda (as opposed to from the function being given the lambda).
Specifically, I don't understand "the return will return from the function", and I'm not confident that I understand the distinction between "the function containing the lambda" and "the function being given the lambda".
Is this interpretation accurate?
If the return function is called from within a lambda, the return action is from the scope of the function containing the lambda (top scope), not the function accepting the lambda (local scope).
With the additional example of:
**Example:** Using `return` in a lambda
# Concatenate three strings into a single string formatted as a list.
function getFruit() {
with("apples", "oranges", "bananas") |$x, $y, $z| {
return("${x}, ${y}, and ${z}")
}

Re: return() errors inside iteration functions
Jo Rhett The thing here is that the return ends up returning from the "top scope". If instead wrapped in a function (like below), then you get a return from the function lexically containing the lambda:
function test() {
with(1) |$num| {
return()
}
notice "not reached"
}
test()

Title: Message Title Henrik Lindberg commented on PUP-7904 Re: return() errors inside iteration functions The documentation is wrong - the return is (and should be) from the lambda's closure as shown by the spec test. Changing this to a docs ticket. I think the docs should be changed to: If called from within a lambda the return will return from the function containing the lambda (as opposed to from the function being given the lambda) Add Comment This message was sent by Atlassian JIRA (v6.4.14#64029-sha1:ae256fe) -- You received this message because you are subscribed to the Google Groups "Puppet Bugs" group.

return() errors inside iteration functions
Issue Type:
Bug
Affects Versions:
PUP 4.10.6
Assignee:
Unassigned
Created:

Major
Reporter:

So the documentation for return() says plainly that it will return from a lambda, ending evaluation of the function.
https://docs.puppet.com/puppet/4.10/function.html#return:
If called from within a lambda the return will return from the function evaluating the lambda.
So let's build a short manifest and use a function that evaluates a lambda:
with(1) |$num| {
return()
