NAME

SWISH::Prog::Index - handle Swish-e indexing

SYNOPSIS

use SWISH::Prog::Index
my $indexer = SWISH::Prog::Index->new(
               format      => 'native2' || 'btree2' || 'swish3',
               config      => SWISH::Prog::Config->new,
               exe         => 'path/to/swish-e',
               verbose     => 0|1|2|3,
               warnings    => 0|1|2|3,
               name        => 'path/to/myindex'
               );
               
$indexer->run;

print "index files: $_" for $indexer->files;

# or from the command line

DirTree.pl some/path | perl -MSWISH::Prog::Index -e go

DESCRIPTION

SWISH::Prog::Index performs Swish-e indexing. For version 2.x of Swish-e this is simply a convenience wrapper around the swish-e binary executable. See SWISH3 for details about how version 3 will work.

FUNCTIONS

go

Magic method to run the indexer with all defaults. See SYNOPSIS for an example.

You might object that the perl line is harder to remember than 'swish-e -v0 -W0 -S prog -i stdin' and it takes 0.1 second longer to run.

True enough. But go() was easy to code in two lines, so I did. And it requires one less keystroke. Laziness is a virtue!

Plus, Swish3 will have a native Perl XS API, and this module will support all versions with go(). See ENVIRONMENT VARIABLES for more details.

go() is the only export of this module.

METHODS

new

Create indexer object.

[TODO parameters]

fh

Get or set the open() filehandle for the swish-e process. CAUTION: don't set unless you know what you're doing.

You can print() to the filehandle using the SWISH::Prog index() method. Or do it directly like:

print { $indexer->fh } "your headers and body here";

The filehandle is close()'d by the DESTROY magic method in this class. So when $indexer goes undef, the indexing process is closed automatically.

rm

Remove the index (all the associated index files). Useful if creating a temp index for merging, etc.

files

Returns a list of all the associated files for the index.

run

Start the indexer on its merry way. Stores the filehandle with the fh method for later access via SWISH::Prog or other methods TBD.

Returns the $indexer object.

SWISH3

If the SWISH3 environment variable is set, SWISH::Prog::Index will load SWISH::Prog::Index::3 and use that interface instead.
