Perl passing argument into eval
- by ehretf
I'm facing an issue using eval function.
Indeed I have some function name inside a SQL database, my goal is to execute those functions within perl (after retrieve in SQL).
Here is what I'm doing, considering that $RssSource-{$k}{Proceed} contains "&test" as a string retrieved from SQL:
my $str2 = "ABCD";
eval "$RssSource->{$k}{Proceed}";warn if $@;
sub test
{
my $arg = shift;
print "fct TEST -> ", $row, "\n";
}
This is working correctly and display:
fct TEST ->
However I would like to be able to pass $str2 as an argument to $RssSource-{$k}{Proceed} but I don't know how, every syntax I tried return an error:
eval "$RssSource->{$k}{Proceed}$str2"
eval "$RssSource->{$k}{Proceed}($str2)"
eval "$RssSource->{$k}{Proceed}"$str2
eval "$RssSource->{$k}{Proceed}"($str2)
May someone tell me how to properly pass an argument to the evaluated function?
Thanks a lot for your help
Regards.
