Hi, > What works as expected: >> var from file.txt.erb: <%= var %>
using var instead of @var produces this warning on puppet 3: *Warning: Variable access via 'var' is deprecated. Use '@var' instead. * and it's explained here: http://docs.puppetlabs.com/guides/templating.html *Historically, all of the variables visible in the current scope were also available as Ruby methods — that is, fqdn, memoryfree, operatingsystem, etc., without the prepended @ sign. This style of reference caused problems when variable names collided with Ruby method names; its use emits deprecation warnings as of Puppet 3 and will be removed in Puppet 4. Please update any existing code which uses it and start any new code out with the @fqdn instance-variable syntax.* > var from file.txt.erb: <%= scope.lookupvar("var") %> yes, we need to use this function if we need to access someothermodule::var, or a hiera variable. however, using this function for all variables in the current scope would be ugly. > The fact that the member variable syntax @var works at all is confusing, > and may be considered a bug. yes. that's what we are saying. dynamic lookup in templates should show a warning in puppet 2.7, and stop working on puppet 3.
