NAME ^

SWISH::Prog::Config - read/write Swish-e config files

SYNOPSIS ^

 use SWISH::Prog::Config;
 
 my $config = SWISH::Prog::Config->new;
 $config->write2();
 $config->read2('path/to/file.conf');
 $config->write3();

DESCRIPTION ^

The SWISH::Prog::Config class is intended to be accessed via SWISH::Prog->new().

See the Swish-e documentation for a list of configuration parameters. Each parameter has an accessor/mutator method as part of the Config object. Some preliminary compatability is offered for SWISH::3::Config with XML format config files.

NOTE: Every config parameter can take either a scalar or an array ref as a value. In addition, you may append config values to any existing values by passing an additional true argument. The return value of any 'get' is always an array ref.

Example:

 $config->MetaNameAlias( ['foo bar', 'one two', 'red yellow'] );
 $config->MetaNameAlias( 'green blue', 1 );
 print join("\n", @{ $config->MetaNameAlias }), " \n";
 # would print:
 # foo bar
 # one two
 # red yellow
 # green blue

METHODS ^

new( params )

Instantiate a new Config object. Takes a hash of key/value pairs, where each key may be a Swish-e configuration parameter.

Example:

 my $config = SWISH::Prog::Config->new( DefaultContents => 'HTML*' );
 
 print "DefaultContents is ", $config->DefaultContents, "\n";

debug

Get/set the debug level. Default is 0.

verbose

Get/set flags affecting the verbosity of the program.

get_opt_names

Class method.

Returns array ref of all the option (method) names supported.

read2( path/file )

Reads version 2 compatible config file and stores in current object. Returns parsed config file as a hashref or undef on failure to parse.

Example:

 use SWISH::Prog::Config;
 my $config = SWISH::Prog::Config->new();
 my $parsed = $config->read2( 'my/file.cfg' );
 
 # should print same thing
 print $config->WordCharacters->[0], "\n";
 print $parsed->{WordCharacters}, "\n";

write2( path/file [,prog_mode] )

Writes version 2 compatible config file.

If path/file is omitted, a temp file will be written using File::Temp.

If prog_mode is true all config directives inappropriate for the -S prog mode in the Native::Indexer are skipped. The default is false.

Returns full path to file.

Full path is also available via file() method.

file

Returns name of the file written by write2().

write3( path/file )

Write config object to file in SWISH::3::Config XML format.

as_hash

Returns current Config object as a hash ref.

all_metanames

Returns array ref of all MetaNames, regardless of whether they are declared as MetaNames, MetaNamesRank or MetaNameAlias config options.

stringify([prog_mode])

Returns object as version 2 formatted scalar.

If prog_mode is true skips inappropriate directives for running the Native::Indexer. Default is false. See write2().

This method is used to overload the object for printing, so these are equivalent:

 print $config->stringify;
 print $config;

ver2_to_ver3( file )

Utility method for converting Swish-e version 2 style config files to SWISH::3::Config XML style.

Converts file to XML format and returns as XML string.

  my $xmlconf = $config->ver2_to_ver3( 'my/file.config' );

If file is omitted, uses the current values in the calling object.

get_stemmer_lang([ fuzzymode ])

Returns the 2-letter language code for the Snowball stemmer corresponding to fuzzymode. If fuzzymode is not defined, calls FuzzyIndexingMode() method on the config object.

TODO ^

IgnoreTotalWordCountWhenRanking defaults to 0 which is not the default in Swish-e. This is to make the RankScheme feature work by default. Really, the default should be 0 in Swish-e itself.
