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 Its ISO 15924 code is "Shaw" 281.
25 This module transliterates English text from the Latin alphabet into
27 the Shavian alphabet.
28 The API has changed since version 0.03 to be object-based.
30 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.

38 Lingua::EN::Alphabet::Shaw->new()
39 Constructor. Currently takes no arguments.
40 $shaw->transliterate($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 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 $shaw->unknown_handler([$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 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 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 $shaw->mapping($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 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 The letters "K" and "L" have no mapping to Shavian letters, and are
81 left alone.
82 $shaw->normalise($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 $shaw->transliterate_html($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
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 It should probably be possible to transliterate in reverse, from
103 Shavian to the conventional alphabet.
104 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 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 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 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 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 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 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 The HTML transliterator should add a "generator" META tag referencing
137 itself, if one is not already present.
138 The HTML transliterator should ignore sections marked as being written
140 in non-English languages.
141 The HTML transliterator should have an option to allow loading
143 documents in chunks, as "HTML::Parser" already does.
144 The mapping() method should have an extra parameter to cause it to map
146 in one direction only.
147 Most of these will be implemented before this module reaches version
149 1.00.
150
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 However, the Mac can handle the Shavian alphabet out of the box.
