61
62Zeal - Read and query Dash/Zeal docsets
63
64=head1 SYNOPSIS
65
66 use Zeal;
67 my $zeal = Zeal->new("/home/mgv/docsets/:/home/mgv/something.docset");
68 $zeal->add('/home/mgv/somethingelse.docset'); # Add another docset
69 $zeal->add('/home/mgv/moredocsets/'); # Add a directory containing docsets
70
71 my $doc = $zeal->query('length'); # Documentation for 'length' in all docsets
72 my @docs = $zeal->query('Test::%', 'perl'); # Documentation for all Test:: perl modules
73 @docs = $zeal->query('perl:Test::%); # Alternative syntax
74
75=head1 DESCRIPTION
76
77Dash is an offline API documentation browser. Zeal.pm is a module for
78reading and querying Dash documentation sets.
79
80This module queries multiple docsets. If you only have one docset, you
81should use the L<Zeal::Docset> module directly.
82
83Available methods:
84
85=over
86
87=item Zeal->B<new>([I<$path>])
88
89Create a new Zeal object. I<$path> is an optional colon delimited
90string for initializing the object. Each of its components is
91recursively scanned for docsets (and can also be a docset itself). If
92I<$path> is not provided, the value of I<$ENV{ZEAL_PATH}> (if defined)
93is used instead.
94
95=item $zeal->B<add>(I<$path>)
96
97Recursively scan a path for docsets, adding them to this object.
98
99=item $zeal->B<sets>([I<$family>])
100
101Return a list of docsets (L<Zeal::Docset> objects) in the given
102family, or in all families if I<$family> is not provided.
103
104=item $zeal->B<query>(I<"$family:$query">)
105
106=item $zeal->B<query>(I<$query>, [I<$family>])
107
108Return a list of documents (L<Zeal::Document> objects) matching a
109query, optionally restricted to a family. In scalar context only one
110such document is returned. I<$query> is a SQL LIKE condition.
