NAME ^

SWISH::Prog::Headers - create document headers for Swish-e -S prog

SYNOPSIS ^

  use SWISH::Prog::Headers;
  use SWISH::3;
  my $f = 'some/file.html';
  my $buf = SWISH::3->slurp( $f ):
  my $headers = SWISH::Prog::Headers->new;
  print $headers->head( $buf, { url=>$f } ), $buf;

DESCRIPTION ^

SWISH::Prog::Headers generates the correct headers for feeding documents to the indexer.

VARIABLES ^

$AutoURL

The $AutoURL package variable is used when no URL is supplied in the head() method. It is incremented each time it is used in head(). You can set it to whatever numerical value you choose. It defaults to $^T.

$Debug

Set to TRUE to carp verbage about content length, etc.

METHODS ^

new

Returns a new object.

init

Called by new().

version

Get/set the API version. Default is 2.

head( buf [, \%opts ] )

Returns scalar string of proper headers for a document.

The only required parameter is buf, which should be the content of the document as a scalar string.

The following keys are supported in %opts. If not supplied, they will be guessed at based on the contents of buf.

version

Which version of the headers to use. The possible values are 2 for Swish-e version 2.x or 3 for Swish3.

url

The URL or file path of the document. If not supplied, a guaranteed unique numeric value will be used, based on the start time of the calling script.

modtime

The last modified time of the document in epoch seconds (time() format). If not supplied, the current time() value is used.

parser

The parser type to be used for the document. If not supplied, it will not be included in the header and Swish-e will determine the parser type. See the Swish-e configuration documentation on determining parser type. See also the SWISH::Prog parser() method.

type

The MIME type of the document. If not supplied, it will be guessed at based on the file extension of the URL (if supplied) or $DefMime. NOTE: MIME type is only used in SWISH::3 headers.

action

Should the doc be added to, updated in or deleted from the index. The url value is used as the unique identifier of the document in the index. The possible values are:

add (default)

If a document with the same url value already exists, a fatal error is thrown.

update

If a document with the same url does not already exist in the index, a fatal error is thrown.

add_or_update

Check first if url exists in the index, and then add or update as appropriate. Since this requires additional processing overhead for every document, it is not the default. It is, however, the safest action to take.

delete

Remove the document from the index. If url does not exist, a fatal error is thrown.

NOTE: The special environment variable SWISH3 is checked in order to determine the correct header labels. If you are using SWISH::3, the environment variable is set for you. Otherwise, set the version with the version method or param.

Headers API ^

See the Swish-e documentation at http://swish-e.org/.
