我正在準備一個索引，其中包含使用國際音標的條目（主要由小寫拉丁字母組成，但有附加內容）.xdy。指定的順序顯示例如，「ʌ」條目出現在「a」條目之前，但是在對鍵進行排序時，會出現預設排序順序：aʌ 出現。後代替前。 （我複製了下面程式碼中出現的排序順序。）我需要指定一些進一步的排序規則嗎？
xelatex
xindy -I latex -o xindy-ipa-sorting.ind -M ipa-alphabet xindy-ipa-sorting.idx
xelatex
xindy-ipa-sorting.tex：
\documentclass{book}
\usepackage{polyglossia}
\setmainfont{Times New Roman}
\usepackage{makeidx,lipsum}
\makeindex
\begin{document}
\lipsum[1]
\index{ʌa}
\index{ʌʌ}
\index{aa}
\index{aʌ}
\printindex
\end{document}

答案1
事實證明，更改關鍵字排序順序涉及定義新語言。在文件中定義新的字母組是不夠的.xdy。 （但是，一旦定義了新語言，您就可以免費獲得字母分組，所以這就是了。）
我遵循了中概述的程序這個答案，對於越南語。不過，我將在此處包含我的代碼，因為它可能比越南語變音符號更容易理解，並且添加步驟utf8-lang.xdy是新的。從答案中xindy-make-rules-0.2已下載和提取的點開始...
在xindy-make-rules-0.2/alphabets目錄中，我建立了一個名為的新資料夾ipa，然後utf8.pl.in使用以下內容建立：
#!/usr/bin/perl
$language = "IPA";
$prefix = "ipa";
$script = "latin";
$alphabet = [
['ʌ', ['ʌ']],
['a', ['a']],
['b', ['b']],
['d', ['d']],
['dʒ', ['dʒ']],
['e', ['e']],
['ɛ', ['ɛ']],
['f', ['f']],
['ɡ', ['ɡ', 'g']],
['ɣ', ['ɣ']],
['h', ['h']],
['i', ['i']],
['j', ['j']],
['k', ['k']],
['l', ['l']],
['m', ['m']],
['n', ['n']],
['o', ['o']],
['p', ['p']],
['q', ['q']],
['r', ['r']],
['s', ['s']],
['ʃ', ['ʃ']],
['t', ['t']],
['tʃ', ['tʃ']],
['u', ['u']],
['ʊ', ['ʊ']],
['w', ['w']],
['x', ['x']],
['z', ['z']],
['ʒ', ['ʒ']],
['ʔ', ['ʔ']],
];
$sortcase = 'Aa';
#$sortcase = 'aA';
@special = ('?', '!', '.', 'letters', '-', '\'', '{', '}');
do 'make-rules.pl';
（這超出了我上面 MWE 的範圍，但我認為這是可以理解的。）
我進行了編輯xindy-make-rules-0.2/alphabets/Makefile，以便INSTDIR（第 7 行）反映了我的安裝位置xindy（在我的例子中"D:\Program Files (x86)\MiKTeX 2.9\xindy\modules\lang"）。
然後在xindy-make-rules-0.2/alphabets目錄中我執行了這些指令：
make utf8
make install
注意：雖然這在當時有效，但當我最近嘗試相同的命令時，它不會建立我的文件，直到我將其包含在（副本的第 66 行）列表中myalphabet/utf8.xdy \。XDYSUTF8xindy-make-rules-0.2/alphabets/Makefile
（因為我是 Windows 用戶，所以我使用 執行這些命令msys。使用mingw32-make對我來說不起作用。）
無論出於何種原因，該腳本都沒有創建我認為至關重要的文件。因此，在xindy/modules/lang/ipa目錄中，我必須建立文件utf8-lang.xdy：
(require "lang/ipa/utf8.xdy")
(define-sort-rule-orientations (forward backward forward forward))
(use-rule-set :run 0
:rule-set ("ipa-alphabetize" "ipa-ignore-special"))
(use-rule-set :run 1
:rule-set ("ipa-resolve-diacritics" "ipa-ignore-special"))
(use-rule-set :run 2
:rule-set ("ipa-resolve-case" "ipa-ignore-special"))
(use-rule-set :run 3
:rule-set ("ipa-resolve-special"))
請注意，此文件需要ipa.xdy，這是上面問題中提供的文件。
回顧一下，現在ipaxindymodules/lang資料夾中應該有一個名為 的子資料夾（在我的例子中"D:\Program Files (x86)\MiKTeX 2.9\xindy\modules\lang"），而該資料夾應包含三個資料：utf8.pl.in、utf8.xdy和utf8-lang.xdy。
完成後，我可以調用xindy如下：
xindy -L IPA -I latex -o example.ind -M ipa example.idx
ipa.xdy是我上面的 MWE 的精簡版本。該文件現在實際上只提供基本選項和標記命令。 IPA 字母表沒有任何特定的內容。
