Hi,
is there a way to iterate with the ruby .times function inside an EPP template?
e.g.
<% $i.times |$x| { -%>
i = <%= $x +1 %>
<% } -%>
The code above seems to need a puppet4 function with name “times”.
Result:
Error: Evaluation Error: Unknown function: 'times'.
When changing to ruby code style another error occurs:
<% $i.times do |$x| -%>
i = <%= $x +1 %>
<% end -%>
Error: Evaluation Error: Error while evaluating a Function Call, epp(): Invalid EPP: Syntax error at ‘|'
thanks,
Martin

Looking at the examples for the 'each' function (https://docs.puppetlabs.com/references/latest/function.html#each) you can replace 'times' with 'each' and I think it'll work.

each can be used on arrays. In my case the variable is an integer.
I want to print stuff $i times into the final file.

You use the range function from stdlib to create an array. For example: range(1,5).each |$x| {notice($x)}

I played around a little bit with the solution mentioned by Michael:
one can use .each on an integer in a template
this results in the same behaviour of .times in ruby.

Yes, that's what I was getting at. I ran out of time for more context.

The same is achieved with an Integer type:

Integer[1,5].each |$x| { notice $x }
It is more efficient than the range function since it does not create an
array of all values in the range.
