I''m trying to exclude uploading a file to certain hosts. In nodes.pp I
have:
node "x.example.com" inherits basenode {
$skip_file = true
}
In the module''s init.pp I have:
file {"/path/to/file":
if $skip_file {
noop => true
}
owner => root,
.
.
I get an error:
err: Could not retrieve catalog: Could not parse for environment
production: Syntax error at ''if''; expected
''}'' at ...
Is this a reasonable way of excluding one file from certain hosts? Also, I
clearly do not understand the syntax for ''if'' (and
it''s very hard to
Google "puppet if statement"), so what am I doing incorrectly?
Thanks

> Please let me know if this update makes more sense:It does, and thank you for updating the page. I think it would be further improved by defining what an "in-statement" and an "around statement" are - the latter, particularly, sounds somewhat nebulous. Perhaps, for now, a little emphasis to differentiate the terms from the rest of the sentence: Puppet currently supports two types of conditionals: <i>in-statement</i> (or inside a resource) and <i>around statements</i>. The only in-statement conditional currently is the <i>selector</i>, and there are two around statement conditionals: <i>case</i> and an <i>if/else structure</i>. But thank you again for a quick enhancement to the documentation.
