NAME¶
Net::DNS::SEC::Tools::BootStrap - Optional loading of Perl modules
SYNOPSIS¶
use Net::DNS::SEC::Tools::BootStrap;
dnssec_tools_load_mods(
PerlModule => 'Additional help/error text'
);
DESCRIPTION¶
The DNSSEC-Tools package requires a number of Perl modules that are only needed
by some of the tools. This module helps determine at run-time, rather than at
installation time, if the right tools are available on the system. If any
module fails to load,
dnssec_tools_load_mods() will
display an error message and calls
exit(). The error
message describes how to install a module via CPAN.
The arguments to
dnssec_tools_load_mods() are given in
pairs. Each pair is a module to try to load (and import) and a supplemental
error message. If the module fails to load, the supplemental error message
will be displayed along with the installation-via-CPAN message. If the error
message consists of the string "noerror", then no error message will
be displayed before the function exits.
CAVEATS¶
The module will try to import any exported subroutines from the module into the
main namespace. This means that the
BootStrap.pm module is
likely to not be useful for importing symbols into other modules. Work-arounds
for this are:
- - import the symbols by hand
-
dnssec_tools_load_mods(
PerlModule => 'Additional help/error text'
);
import PerlModule qw(func1 func2);
func1(arg1, arg2);
- - call the fully qualified function name
-
dnssec_tools_load_mods(
PerlModule => 'Additional help/error text'
);
PerlModule::func1(arg1, arg2);
