Hi!
I'm doing my first Nagios plugin based on Nagios::Plugins and I noticed that it automatically supports --extra-opts.
So I did my first attempt with this feature as it seem to well fit my needs.
unfortunately I observed 2 strange behaviours:
-
I had an argument "msg|message" and this led to some weird parsing of the extra opts. My config file was like this:
[experiment] percent=1 message=%d OKThe result was percent was undefined and msg was set to "--percent".
When I changed the argument to "message|msg", it worked. Now percent is set to 1 and message is set to '"%d OK"'.
And this leads to my second strange behaviour:
-
Every value, which contains spaces, is automatically quoted. So instead of having just
I get%d OK
. and I think this is a bug."%d OK"
Update
Some code to play with:
use strict; use warnings; use Nagios::Plugin; use Data::Dumper; my $n=Nagios::Plugin->new(version=>1,usage=>""); $n->add_arg("percent","",undef,0); $n->add_arg("msg|message=s","",undef,0); $n->getopts(); print Dumper $n->opts
Output is (shortened)
$VAR1 = bless( { : : 'msg' => '--percent', 'verbose' => 0, 'usage' => undef, 'percent' => undef, : }, 'Nagios::Plugin::Getopt' );
Which is wrong. If you change "msg|message=s" to "message|msg=s" the output will be almost correct:
$VAR1 = bless( { : : 'percent' => 1, 'version' => undef, 'message' => '"%d OK"', }, 'Nagios::Plugin::Getopt' );
More Updates
Quoting isn't done properly, I think. When I use this configuration file:
[experiment] percent=1 message="%d" OK
I get a very unusual quoted string: ""%d" OK"
