I'm new to Puppet and learning the program and language so this question
might seem novice. I'm confused why I can assign an escape character to a
variable but not inside any collection types (arrays or hashes). I was
doing the simply motd puppet module and I created this:
$red = "^[[0;31m"
$green = "^[[0;32m"
$white = "^[[0;33m"
$bold = "^[[1m"
$unbold = "^[[22m"
...
Those "^[" characters are actual escape characters (a.k.a. echo -e
\033[0;31m...). When I define my motd variable (which has the contents of
/etc/motd) I can do this:
$motd = @("END")
You are connecting to: *$**{bold}*${facts[hostname]}.${facts[networking][
'domain']}
*${unbold}......END*
This works when I apply my manifest. Well, I thought having all those
variables is stupid so I wanted to put them in a hash and just reference
them by key:
color = {
'red' => "^[[0;31m",
'green' => "^[[0;32m",
'white' => "^[[0;33m",
'bold' => "^[[1m",
'unbold' => "^[[22m",
}
...
$motd = @("END")
You are connecting to: *$**{color['bold']}*${facts[hostname]}.${facts[
networking]['domain']}${color['unbold']}
*......END*
However this produces an error
$puppet apply --environment sandbox ./manifests/
Error: Illegal attempt to assign to 'a Name'. Not an assignable reference
at /etc/puppetlabs/code/environments/sandbox/modules/motd/manifests/init.pp:
53:2 on node fenix.harmonywave.com
I get the same issue if I try using an array as well. I'm fine using a
variable for each color, I'm just curious why they can't be assigned to
collection types.
Thanks,
Joshua
