I want to put a/few values in a file using puppet but when I do the following:

<% @_zoo_cfgs.each do |zooconfig| -%>
<%=zooconfig -%>
<% end -%>

I get the below content in the file. I have a new line and a tab before the content and a new line after the content as well:

But I want the below content:

with no extra white spaces in the file before or after the value. Could anyone please let me know how could this be done? Any help will be highly appreciated.

Can you put your 'got' and 'wanted' content in a 'code' block? I can't tell a difference in how it's formatted

I can't tell a difference with the way you have your question formatted above. I'll try to answer what I can with what I can discern..

If I recreate your above example in a single .pp file for testing, this is the result that I get.

$_zoo_cfgs = ['one','two','three']

$content = inline_template('<% @_zoo_cfgs.each do |zooconfig| -%>
<%=zooconfig -%>
<% end -%>')


and the output

$ puppet apply test.pp
Notice: Scope(Class[main]): onetwothree
Notice: Compiled catalog for myhost in environment production in 0.05 seconds
Notice: Finished catalog run in 2.36 seconds

I see the entirety of the output on a single line, no whitespace before or after. Do you have an extra newline before or after the code that you have shown above? any whitespace in the template file outside of erb templating indicators <% ... %> will show up in the file?

<%= @_zoo_cfgs.join('') -%>
