Variables inside variables

[Jonathan Gazeley]

Hi folks,

Short version:

I want to use a variable inside a variable to access a fact. Is this
possible?

Long version:

Facter provides facts $::ipaddress and $::netmask which figure out which
is your primary interface and then return values like $::ipaddress_eth0
and $::netmask_eth0. However there is not a $::network fact to reflect
$::network_eth0.

I have a custom fact $::gateway_dev which returns the name of the
primary interface. Is it possible to access the variable like
${::network_${::gateway_dev}} ?

Thanks,
Jonathan

I achieve this by using the getvar function in stdlib. For example:

getvar("::network_${::gateway_dev}")
