17 | =head1 DESCRIPTION |
18 | |
19 | For an overview of the package, see the documentation for the |
20 | Text::Tradition::Graph module. |
21 | |
22 | This module is meant for use with certain of the other Parser classes |
23 | - whenever a list of variants is given with reference to a base text, |
24 | these must be joined into a single collation. The parser should |
25 | therefore make a list of variants and their locations, and BaseText |
26 | will join those listed variants onto the reference text. |

33 | |
34 | parse( $graph, %opts ); |
35 | |
36 | Takes an initialized graph and a set of options, which must include: |
37 | - 'base' - the base text referenced by the variants |
38 | - 'format' - the format of the variant list |
39 | - 'data' - the variants, in the given format. |

44 | my( $tradition, %opts ) = @_; |

45 | |
46 | my $format_mod = 'Text::Tradition::Parser::' . $opts{'format'}; |
47 | load( $format_mod ); |
48 | my @apparatus_entries = $format_mod->can('read')->( $opts{'data'} ); |

54 | merge_base( $graph, 'reference.txt', @apparatus_entries ) |
55 | |
56 | Takes three arguments: a newly-initialized Text::Tradition::Graph |
57 | object, a text file containing the reference text, and a list of |
58 | variants (apparatus entries). Adds the base text to the graph, and |
59 | joins the variants to that. |
60 | |
61 | The list of variants is an array of hash references; each hash takes |
62 | the form |
63 | { '_id' => line reference, |
64 | 'rdg_0' => lemma reading, |
65 | 'rdg_1' => first variant, |
66 | ... # and so on until all distinct readings are listed |
67 | 'WitnessA' => 'rdg_0', |
68 | 'WitnessB' => 'rdg_1', |
69 | ... # and so on until all witnesses are listed with their readings |
70 | } |
71 | |
72 | Any hash key that is not of the form /^rdg_\d+$/ and that does not |
73 | begin with an underscore is assumed to be a witness name. Any 'meta' |
74 | information to be passed must be passed in a key with a leading |
75 | underscore in its name. |
