[Puppet Users] if statement: ''true'' from left operand of ''in'' expression is not a string
Hi *,
using the following snippet of code ..
------------------------------------------------------------------------
[...]
7 if ! ($installplugins in [ true, false ]) {
8 fail("nrpe installplugins parameter must be true or false")
9 }
[...]
24 if $installplugins == true {
25 package { ["mypluginpackage",
26 ensure => installed }
27 }
[...]
------------------------------------------------------------------------
.. puppet throws the following error:
------------------------------------------------------------------------
err: Could not retrieve catalog from remote server: Error 400 on SERVER:
''true'' from left operand of ''in'' expression
is not a string at
/etc/puppet/manifests/classes/monitoring.pp:7 on node puppet
------------------------------------------------------------------------
This snippet of code I got from the puppet style-guide:
http://docs.puppetlabs.com/guides/style_guide.html#class-inheritance
-> see the bluetooth class example
Any ideas? What am I missing?
Btw. I''m running a self-build version of puppet 2.6.4 without
additional
patches ...
Many thanks
Jan

Sorry that''s probably a bit premature. Ignore me.

From the message, I would guess that this would (also) work: if ! ("$installplugins" in [ true, false ]) { fail("nrpe installplugins parameter must be true or false") } (Since it''s the *left* side of the in operator that Puppet complains about not being a string.) Of course, it''s quite inconsistent that if one assigns bareword true to a variable, one cannot subsequently compare that variable against the same value, or against an array that (appears to) contain that value. I call bug, and I recommend filing a ticket. John -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
