constant string in regular expression

hello!

i am new to perl. i searched the online documentation for this
problem, but i didn't find an answer.

here is a part of my code:

[...]
use constant _GROUP => "gruppe";
[...]
if ($configLine =~ /^\s*_GROUP\s+(.+?)\s*$/) {
[...]

of couse in the regexp the character sequence _GROUP does not get
replaced, but i want that it is regarded as the name of the constant
and therefore replaced by "gruppe".

i hope that my post is understandable enough.

many thanks in advance,

~michael

Use the Readonly module instead:

use Readonly;
Readonly::Scalar my $_GROUP => "gruppe";
....
if ($configLine =~ /\s*$_GROUP\s+(.+?)\s*$/) {
....

Use the Readonly module instead:

use Readonly;
Readonly::Scalar my $_GROUP => "gruppe";

if ($config
