10 [B<-clean>] [B<-noclean>]
11 [B<-cpan> I<url or directory>]

17 [B<-trust_mtime>] [B<-notrust_mtime>]
18
19 =head1 DESCRIPTION
20
21 This is a port of C<cpanwait> from L<WAIT> perl search engine to node API of
22 Hyper Estraier.
23
24 All the hard work was done by Ulrich Pfeifer who wrote all parsers and
25 formatters. I just added support for Hyper Estraier back-end after.
26
27 B<This documentation is somewhat incomplete and off-the-sync with code.>
28
29 =head1 OPTIONS
30
31 =over 5
32
33 =item B<-clean> / B<-noclean>
34
35 Clean the table befor indexing. Default is B<off>.
36
37 =item B<-cpan> I<url or directory>
38
39 Default directory or URL for indexing. If an URL is given, there
40 currently must be a file F<indices/find-ls.gz> relative to it which
41 contains the output of C<find . -ls | gzip>.
42 Default is F<ftp://ftp.rz.ruhr-uni-bochum.de/pub/CPAN>.
43
44
45 =item B<-node> I<http://localhost:1978/node/cpan>
46
47 Specify node URI
48
49 =item B<-force>
50
51 Force reindexing, even if B<cpan> thinks files are up to date.
52 Default is B<off>
53
54 =item B<-keep> I<directory>
55
56 If fetching from a remote server, keep files in I<directory>. Default is
57 F</app/unido-i06/src/share/lang/perl/96a/CPAN/sources>.
58
59 =item B<-match> I<regexp>
60
61 Limit to patches matching I<regexp>. Default is F<authors/id/>.
62
63 =item B<-test> I<level>
64
65 Set test level, were B<0> means normal operation, B<1> means, don't
66 really index and B<2> means, don't even get archives and examine them.
67
68 =item B<-trust_mtime> / B<-notrust_mtime>
69
70 If B<on>, the files mtimes are used to decide, which version of an
71 archive is the newest. If b<off>, the version extracted is used
72 (beware, there are far more version numbering schemes than B<cpan> can
73 parse).

847
848 HyperEstraier::WAIT::Table
849
850 =head1 DESCRIPTION
851
852 This is a mode that emulates C<WAIT::Table> functionality somewhat.
853
854 There are some limitations and only one key attribute is supported (and used
855 for C<@uri>).
856
857 =head2 Porting from WAIT to this module.
858
859 Since only one key is supported (and used as C<@uri> attribute),
860 use first parametar of C<keyset> as C<key>.
861
862 Full text index is specified as C<invindex>, but you need just name of fields.
863
864 You will probably need to add
865
866 use WAIT::Parse::Base;
867
868 to your code after you remove C<WAIT::Config> and C<WAIT::Database>.
