75 | =head1 DESCRIPTION | |
76 | ||
77 | Dash is an offline API documentation browser. Zeal.pm is a module for | |
78 | reading and querying Dash documentation sets. | |
79 | ||
80 | This module queries multiple docsets. If you only have one docset, you | |
81 | should use the L<Zeal::Docset> module directly. | |
82 | ||
83 | Available methods: | |
84 | ||
85 | =over | |
86 | ||
87 | =item Zeal->B<new>([I<$path>]) | |
88 | ||
89 | Create a new Zeal object. I<$path> is an optional colon delimited | |
90 | string for initializing the object. Each of its components is | |
91 | recursively scanned for docsets (and can also be a docset itself). If | |
0c1fd452 | 92 | I<$path> is not provided, the value of I<$ENV{ZEAL_PATH}> (if defined) |
c1c9c817 MG |
93 | is used instead. |
94 | ||
95 | =item $zeal->B<add>(I<$path>) | |
96 | ||
97 | Recursively scan a path for docsets, adding them to this object. | |
98 | ||
99 | =item $zeal->B<sets>([I<$family>]) | |
100 | ||
101 | Return a list of docsets (L<Zeal::Docset> objects) in the given | |
102 | family, 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<$family>]) | |
107 | ||
108 | Return a list of documents (L<Zeal::Document> objects) matching a | |
109 | query, optionally restricted to a family. In scalar context only one | |
110 | such document is returned. I<$query> is a SQL LIKE condition. | |
