Puppet users - Feb 2007 - use of $name

Hello

The following chunk is within a class definition. ${name} is being  
exchanged with an empty string:

     remotefile { "/${server_xml}":
         owner => tomcat, group => tomcat, mode => 600,
         source => "${ftoe_src_prefix_dev}${name}.jvm1"
     }

However in the following chunk, lower down in the same class  
definition, ${name} is being exchanged with "/usr/local/tomcat/conf/ 
tomcat-users.xml" as I would expect:

     remotefile { "/usr/local/tomcat/conf/tomcat-users.xml":
         owner => tomcat, group => tomcat, mode => 600,
         source => "${ftoe_src_prefix_dev}${name}"
     }

i can make the first one work by making the source line:

         source => "${ftoe_src_prefix_dev}/${server_xml}.jvm1"

but I don''t know why this is necessary. Is it a bug? Or am I doing  
something wrong / expecting too much?

Thanks
Jesse

Actually, the ${name} in the second remotefile above doesn''t work  
properly either, it kind of works but the file (tomcat-users.xml) is  
created as a directory instead of a file. Changing:

to

> tomcat-users.xml"

makes it work correctly, however it seems that it should be  
unnecessary to have that long file path written out twice. Why  
doesn''t ${name} work here?

Thanks

This will never work because $name is evaluated within the context of  
the class, not the context of the remotefile, so it''s actually  
unbound and evaluates to "".

If you have a lot of these, it might be worth making another wrapper  
around remotefile that does that for you.
