App::Cmdline::Options::ExtDB - extended set of database-related options for command-line applications
version 0.1.0
# In your module that represents a command-line application:
sub opt_spec {
my $self = shift;
return $self->check_for_duplicates (
[ 'check|c' => "only check the configuration" ],
...,
$self->composed_of (
'App::Cmdline::Options::ExtDB', # here are the database options added
'App::Cmdline::Options::Basic', # here may be other options
)
);
}
This is a kind of a role module, defining a particular set of command-line options and their validation. See more about how to write a module that represents a command-line application and that uses this set of options in App::Cmdline.
Particularly, this module extends the basic database-related options, adding an option for showing how the database options have been set. It inherits from App::Cmdline::Options::DB module, and, therefore, provides the same options defined there, and it adds the following option:
[ 'dbshow' => "show database access properties" ],
It prints (on STDOUT) values given to the database-related options. For example:
senger@ShereKhan2:myapp --dbshow --dbname Emma --dbpasswd vrrr -dbhost 12.13.14.15 DBNAME: Emma DBHOST: 12.13.14.15 DBPORT: 3306 DBUSER: reader DBPASS: ...given but not shown DBSOCK: n/a
