5     cpanest - generate an Hyper Estraier index for CPAN
6    
7     =head1 SYNOPSIS
8    
9     B<cpanest>
10     [B<-clean>] [B<-noclean>]
11     [B<-cpan> I<url or directory>]
12     [B<-node> I<node_uri>]
13     [B<-force>] [B<-noforce>]
14     [B<-keep> I<directory>]
15     [B<-match> I<regexp>]
16     [B<-test> I<level>]
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).

823     HyperEstraier::WAIT::Table
824    
825     =head1 DESCRIPTION
826    
827     This is a mode that emulates C<WAIT::Table> functionality somewhat.
828    
829     There are some limitations and only one key attribute is supported (and used
830     for C<@uri>).
831    
832     =head2 Porting from WAIT to this module.
833    
834     Since only one key is supported (and used as C<@uri> attribute),
835     use first parametar of C<keyset> as C<key>.
836    
837     Full text index is specified as C<invindex>, but you need just name of fields.
838    
839     You will probably need to add
840    
841     use WAIT::Parse::Base;
842    
843     to your code after you remove C<WAIT::Config> and C<WAIT::Database>.
