Zeal::Docset - Class representing a Dash/Zeal docset


  use Zeal::Docset;
  my $ds = Zeal::Docset->new('/home/mgv/docsets/Perl.docset');
  say $ds->$path;  # /home/mgv/docsets/Perl.docset
  say $ds->name;   # Perl
  say $ds->id;     # perl
  say $ds->family; # perl

  # In SQL LIKE, % is .* and _ is .
  my @matches = $ds->query('perlopen%'); # finds perlopenbsd and perlopentut
  my $doc = $ds->query('perlsec'); # A Zeal::Document object for perlsec
  my $html = $ds->get('perls_c'); # HTML documentation of perlsec
  my @docs = $ds->list; # all documents


Dash is an offline API documentation browser. Zeal::Docset is a class
representing a Dash/Zeal docset.

Available methods:


=item Zeal::Docset->B<new>(I<$path>)

Create a Zeal::Docset object from a given docset. I<$path> should be
the path to a F<something.docset> directory.

=item $ds->B<path>

The path to the docset folder.

=item $ds->B<plist>

A hashref with the contents of Info.plist.

=item $ds->B<dbh>

A DBI database handle to the docSet.dsidx index.

=item $ds->B<name>

The name of this docset. Equivalent to
C<< $ds->plist->{CFBundleName} >>

=item $ds->B<id>

The identifier of this docset. Equivalent to
C<< $ds->plist->{CFBundleIdentifier} >>

=item $ds->B<family>

The family this docset belongs to. Dash uses this as the keyword for
restricting searches to a particular family of docsets. Equivalent to
C<< $ds->plist->{DocSetPlatformFamily} >>

=item $ds->B<fetch>(I<$path>)

Internal method for fetching the HTML content of a document. I<$path>
is either the path to the document relative to C<< $ds->B<path> >> or

=item $ds->B<query>(I<$cond>)

In list context, return all documents (L<Zeal::Document> instances)
matching I<$cond>. In scalar context, return one such document.
I<$cond> is a SQL LIKE condition.

=item $ds->B<get>(I<$cond>)

The HTML content of one document that matches I<$cond>.
I<$cond> is a SQL LIKE condition.

This method is shorthand for C<< $ds->query(I<$cond>)->fetch >>.

=item $ds->B<list>

The list of all documents (L<Zeal::Document> instances) in this
