Text::Karma - Process (and optionally store) karma points


 use 5.010;
 use strict;
 use warnings;
 use Text::Karma;
 use DBI;

 my $dbh = DBI->connect("dbi:SQLite:dbname=karma.sqlite","","");
 my $karma = Text::Karma(dbh => $dbh);

     nick  => 'someone',
     who   => 'someone!from@somewhere',
     where => '#in_here',
     str   => "this thing++ is awesome # some cool comment",

 say "Karma for thing: ".$karma->get_karma("thing");



Constructs and returns a Text::Karma object. Takes the following arguments:

'dbh', an optional database handle.

'table_prefix', a prefix to use for the table that will be created if you supplied a database handle.


Processes karma from a string, and returns the results. They will also be stored in the database if you supplied a database handle to new. Takes the following arguments:

'nick', the nickname of the person who wrote the text. Required.

'who', the full name of the person who wrote the text. Required.

'where', the place where the person wrote the text. Required.

'str', the text that the person wrote. Required.

'self_karma', whether to allow people to affect their own karma. Optional. Defaults to false.

The return value will be an arrayref containing a hashref for each karma operation. They will have the following keys:

'subject', the subject of the karma operation (e.g. 'foo' in 'foo++').

'op', the karma operation (0 if it was '--', 1 if it was '++').

'comment', a potential comment for the karma change.


This method returns the karma for a given subject from the database. Takes one argument, a subject to look up. If the subject is unknown, nothing is returns. Otherwise, you'll get a hashref with the following keys:

'up', number of karma upvotes for the subject.

'down', number of karma downvotes for the subject.

'score', the karma score for the subject ('up' minus 'down').
