I have two variables and I want to compare them to each other. However,

Something like this:
$variable1 = 'foo'
$variable2 = 'foobar'
if($variable2 =~ /$variable1/) {
notify {"it works":}
} else {
notify {"regex did not work":}
}
root@test-slincsplunk1101r(~)# puppet apply /srv/tmp/test.pp
notice: regex did not work
notice: /Stage[main]//Notify[regex did not work]/message: defined
'message' as 'regex did not work'
How can I do this?
The docs say it's not available.
https://docs.puppetlabs.com/puppet/latest/reference/lang_datatypes.html#regular-expressions
"Alternate forms of regex quoting are not allowed and Ruby-style
variable interpolation is not available."

In Puppet 3.7 with future parser the right hand side can be any
expression that evaluates to a regular expression or a string (if string
it is
interpreted as a regexp and the string should not be enclosed in / /).
This will be standard in Puppet 4.0.
e.g
# The variable is a regexp string
if($variable2 =~ $variable) {
#...
# interpolated as part of a regext
if($variable2 =~ "xxxxx$variable") {
#...
Hope that helps
