Need to substitute a string in a file using puppet

I need help replacing a word in an apache Vhost's file using Puppet. My Vhost file looks like:

<VirtualHost *:80>
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{SERVER_NAME}/$1 [R,L]
</VirtualHost>

Now I want to substitute the * with the $fqdn facter variable on the first line. I don't want to use the apache module from Puppet Forge. I found file_line from the stdlib module but it is not able to substitute with a facter variable.

I could use the exec resource type which will run a sed command to replace * with the hostname, but I want to avoid doing that. Is there any other way to do this?

Ok, so I found my answer:

append_on_no_match => false,

Added that to the match statement; seems to prevent appending if no match is found.

The problem with this answer, is that if puppet doesn't match a string it still appends, and this cannot always happen, in fact, it often cannot happen.

I don't have an answer, but perhaps someone else might. I would prefer a puppet answer vs me writing a script (with sed or perl).

Sincerely,

Some puppet user....

You can in fact use file_line here:

include stdlib
$fqdn = $facts['fqdn']
file_line { 'virtual_host':
  ensure => present,
  path   => '/path/to/httpd.conf',
  line   => "<VirtualHost ${fqdn}:80>",
  match  => '<VirtualHost \*:80>',
}
