I fixed the problem by prefixing the one-line definition of basename with a
return.
Should I infer Puppet doesn't support the standard Ruby mechanism of
returning the last evaluated result within a function?
I did have:
module Puppet::Parser::Functions
newfunction(:basename, :type => :rvalue) do |args|
File.basename(*args)
end
end
..which resulted in:
err: Could not retrieve catalog from remote server: Error 400 on SERVER:
undefined method `basename'
I now have:
module Puppet::Parser::Functions
newfunction(:basename, :type => :rvalue) do |args|
return File.basename(*args)
end
end
..which works like a charm.
Cheers,
David
