>SYNOPSIS</a></h1>
<pre> # 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
)
);
}</pre>
<h1><a class='u' href='#___top' title='click to go to top of document'
name="DESCRIPTION"
>DESCRIPTION</a></h1>
<p>This is a kind of a <i>role</i> 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 <a href="http://search.cpan.org/perldoc?App%3A%3ACmdline" class="podlinkpod"
>App::Cmdline</a>.</p>
<h1><a class='u' href='#___top' title='click to go to top of document'
name="OPTIONS"
>OPTIONS</a></h1>
<p>Particularly, this module extends the basic database-related options, adding an option for showing how the database options have been set. It inherits from <a href="http://search.cpan.org/perldoc?App%3A%3ACmdline%3A%3AOptions%3A%3ADB" class="podlinkpod"
>App::Cmdline::Options::DB</a> module, and, therefore, provides the same options defined there, and it adds the following option:</p>
<pre> [ 'dbshow' => "show database access properties" ],</pre>
<h2><a class='u' href='#___top' title='click to go to top of document'
name="--dbshow"
>--dbshow</a></h2>
<p>It prints (on STDOUT) values given to the database-related options. For example:</p>
<pre> 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</pre>
