SYNOPSIS

13         use Lingua::EN::Alphabet::Shaw;

15         my $shaw = Lingua::EN::Alphabet::Shaw->new();
16         print $shaw->transliterate('I live near a live wire.');

DESCRIPTION

19       The Shaw or Shavian alphabet was commissioned by the will of the
20       playwright George Bernard Shaw in the early 1960s as a replacement for
21       the Latin alphabet for representing English.  It is designed to have a
22       one-to-one phonemic (not phonetic) mapping with the sounds of English.
23
24       Its ISO 15924 code is "Shaw" 281.
25
26       This module transliterates English text from the Latin alphabet into
27       the Shavian alphabet.
28
29       The API has changed since version 0.03 to be object-based.
30
31       If you find an error in the translation database, you can change it
32       yourself at http://shavian.org.uk/wiki/ .  You may download a current
33       copy of the dataset at http://shavian.org.uk/set/ .  If you want to
34       override the database shipped with this module, place the new copy at
35       ~/.cache/shavian/shavian-set.sqlite and it will be used in preference.
36

METHODS

38   Lingua::EN::Alphabet::Shaw->new()
39       Constructor.  Currently takes no arguments.
40
41   $shaw->transliterate($phrase)
42       Returns the transliteration of the given phrase into the Shavian
43       alphabet.  Can handle multi-word phrases.  Does a reasonable job
44       resolving homonym ambiguity ("does he like does?").
45
46       If you pass multiple arguments, the results will be concatenated, and
47       only the odd-numbered arguments will be transliterated.  The state of
48       homonym resolution is maintained.  This allows you to embed chunks of
49       text which should not be transliterated into the line, such as XML
50       tags.
51
52   $shaw->unknown_handler([$handler])
53       If a word is not found in the translation database, the transliteration
54       routines will call a particular handler to find out what to do, with
55       the unknown word as both its first and second arguments.  (This is to
56       allow later expansion; see BUGS AND ISSUES, below.)  The result of the
57       handler should be a string, which will be inserted into the result of
58       the transliteration routine at the correct place.
59
60       This method allows you to set a new handler by passing it as an
61       argument.  If you pass no argument, this method returns the current
62       handler.
63
64       The default handler only returns its argument.  A replacement handler
65       could, for example, make an attempt at guessing the transliteration; it
66       could die, to abort the transliteration process; it could return its
67       argument but also store the new value in a table so that a list of
68       missing words could later be reported to the user.
69
70   $shaw->mapping($phrase)
71       There is a quasi-standard mapping of the conventional alphabet onto the
72       Shavian alphabet.  This method maps Shavian text into the conventional
73       alphabet and vice versa. It does not transliterate.  Think of this as a
74       kind of ASCII-armouring.
75
76       Various versions of the standard map the naming dot to "G", "B", and
77       "/".  This method does not support "/", but maps both "G" and "B" to
78       the naming dot; in reverse, it maps the naming dot to "G".
79
80       The letters "K" and "L" have no mapping to Shavian letters, and are
81       left alone.
82
83   $shaw->normalise($shavian_text)
84       Certain letters in the Shavian alphabet are ligatures of pairs of other
85       letters: because of this, these pairs should not exist separately.
86       (For example, the letter YEW is a ligature of YEA and OOZE.) This
87       method replaces these pairs with their ligature equivalents.
88
89   $shaw->transliterate_html($html)
90       Given a block of text in the conventional alphabet which is formatted
91       as HTML, this will make a reasonable attempt at returning the same text
92       transliterated into the Shavian alphabet.  It is aware of which tags
93       commonly break the flow of sentences, and handles homonym resolution
94       accordingly.
95

BUGS AND ISSUES

97       There should be a version of the main transliteration method which
98       returned a list of hashes, each of which gave the source and
99       destination forms of a word, part of speech and disambiguation
100       information, and a marking of the source (CMUDict or Shavian Wiki).
101
102       It should probably be possible to transliterate in reverse, from
103       Shavian to the conventional alphabet.
104
105       It should be possible to handle other alternative scripts, such as
106       Deseret and Tengwar.  This shouldn't be very difficult.  It would also
107       allow representation in the IPA, which would mean this module could be
108       used for simple text-to-speech processing.
109
110       The portion of the database which is taken from CMUdict exhibits
111       unhelpful mergers (notably father/bother).  There isn't much that can
112       be done about this except extending the Shavian wiki further.  In
113       addition, in some cases it does not use the letters ARRAY and ADO in
114       unstressed syllables as they should be; this could and should be fixed.
115
116       It would be useful on initialisation to read a text file in a standard
117       location, which gave a local mapping overriding the database for given
118       words.
119
120       It would be helpful if there was a callback for any words found from
121       the CMUDict data rather than from the Shavian Wiki data, so that the
122       wiki could be updated.
123
124       The HTML transliterator should mark its output as being encoded in
125       UTF-8, whatever the source encoding.  (Shavian cannot be represented in
126       any other standard encoding.)
127
128       The HTML transliterator should have an option which put a span around
129       each word whose title was the word's spelling in the conventional
130       alphabet, in the manner of translate.google.com.
131
132       The HTML transliterator should have an option to rewrite the
133       destinations of links, and to add a target to them, so that it can be
134       used by a web script to link back to itself.
135
136       The HTML transliterator should add a "generator" META tag referencing
137       itself, if one is not already present.
138
139       The HTML transliterator should ignore sections marked as being written
140       in non-English languages.
141
142       The HTML transliterator should have an option to allow loading
143       documents in chunks, as "HTML::Parser" already does.
144
145       The mapping() method should have an extra parameter to cause it to map
146       in one direction only.
147
148       Most of these will be implemented before this module reaches version
149       1.00.

FONTS

152       You will need a Shavian Unicode font to use this module.  There are
153       several such fonts at http://marnanel.org/shavian/fonts/ .  Please be
154       sure to get a Unicode font and not one with the "Latin mapping".
155
156       However, the Mac can handle the Shavian alphabet out of the box.
