NAME

6       Biblio::EndnoteStyle - reference formatting using Endnote-like
7       templates
8

SYNOPSIS

10        use Biblio::EndnoteStyle;
11        $style = new Biblio::EndnoteStyle();
12        ($text, $errmsg) = $style->format($template, \%fields);
13

DESCRIPTION

15       This small module provides a way of formatting bibliographic references
16       using style templates similar to those used by the popular reference
17       management software Endnote (http://www.endnote.com/).  The API is
18       embarrassingly simple: a formatter object is made using the class's
19       constructor, the "new()" method; "format()" may then be repeatedly
20       called on this object, using the same or different templates.
21
22       (The sole purpose of the object is to cache compiled templates so that
23       multiple "format()" invocations are more efficient than they would
24       otherwise be.  Apart from that, the API might just as well have been a
25       single function.)

METHODS

28   new()
29        $style = new Biblio::EndnoteStyle();
30
31       Creates a new formatter object.  Takes no arguments.
32
33   debug()
34        $olddebug = $style->debug(1);
35
36       Turns debugging on or off and returns the old debugging status.  If an
37       argument is provided, then debugging is turned either on or off
38       according to whether then argument is true or false.  In any case, the
39       old value of the debugging status is returned, so that a call with no
40       argument is a side-effect-free inquiry.
41
42       When debugging is turned on, compiled templates are dumped to standard
43       error.  It is not pretty.
44
45   format()
46        ($text, $errmsg) = $style->format($template, \%fields);
47
48       Formats a reference, consisting of a hash of fields, according to an
49       Endnote-like template.  The template is a string essentially the same
50       as those used in Endnote, as documented in the Endnote X User Guide at
51       http://www.endnote.com/support/helpdocs/EndNoteXWinManual.pdf pages
52       390ff.  In particular, pages 415-210 have details of the recipe format.
53       Because the templates used in this module are plain text, a few special
54       characters are used:
55
56       ¬   Link adjacent words.  This is the "non-breaking space" described on
57           page 418 of the EndNote X
58
59       |   Forced Separation of elements that would otherwise be dependent.
60
61       ^   Separator for singular/plural aternatives.
62
63       `   Used to prevent literal text from being interpreted as a fieldname.
64
65       The hash of fields is passed by reference: keys are fieldnames, and the
66       corresponding values are the data.  PLEASE NOTE AN IMPORTANT
67       DIFFERENCE.  Keys that do not appear in the hash at all are not
68       considered to be fields, so that if they appear in the template, they
69       will be interpreted as literal text; keys that appear in the hash but
70       whose values are undefined or empty are considered to be fields with no
71       value, and will be formatted as empty with dependent text omitted.  So
72       for example:
73
74        $style->format(";Author: ", { Author => "Taylor" }) eq ":Taylor: "
75        $style->format(";Author: ", { Author => "" }) eq ";"
76        $style->format(";Author: ", { xAuthor => "" }) eq ";Author: "
77
78       "format()" returns two values: the formatted reference and an error-
79       message.  The error message is defined if and only if the formatted
80       reference is not.
