我希望创建一个索引方案,其中的条目可以分别打印在不同的位置,以便允许在条目之间添加各种文本和注释,或者允许条目出现在这样的注释中,例如在括号之间。(因此,我所追求的不同于每个条目包含多个数据的索引,如问题“手动添加附加数据的索引”。)
因此我不能(据我所知!)使用通常的索引工具,因为它们不允许这种“传播”。
我写了以下三个命令,一个用于索引条目的第一次出现,一个用于后续出现,一个用于打印索引,其逻辑在注释掉的行中进行了解释。
我遇到的问题如下所示:\thepage 有时会给出错误的值(页面的开始出现在段落中的,而不是实际的当前的在某些情况下,索引条目会在其本身出现的页面上丢失,这会导致一些索引条目在跨越多页的段落中出现时丢失。
\documentclass[oneside,10pt]{article}
\usepackage{ifthen}
\newcommand\IDx[1]
{%
\newcounter{#1}%
%Not yet used: will be used in \INDEX (see explanation below)
\newcounter{#1page}%
%this counter is redefined with the index is incremented, so as to allow for a comparison of the indexed page with subsequent entries
%As this is the first entry, I redefine it:
\setcounter{#1page}{\thepage}%
%Then this counter:
\newcounter{#1index}%
%registers the number of pages that have been indexed,
%which we will need later on, in \INDEX, in order to know how many pages to look for
%As this is the first entry, we increment it:
\refstepcounter{#1index}%
%We put there a unique label which \INDEX will then look for to get the current page number
\label {#1=\csname the#1index\endcsname}%
}%
\newcommand\IDX[1]
{%
%Then we compare the value that #1page has had at the last point of index with the value of the current page
%If they are the same, we do nothing: the page is already indexed.
%If they differ, we repeat the scheme of above
\ifthenelse {%
\equal {\csname the#1page\endcsname}
{\thepage}%
}%
{}
{%
\refstepcounter{#1index}%
\label {#1=\csname the#1index\endcsname}%
\setcounter{#1page}{\thepage}%
}%
}%
\newcommand\INDEX[1]
{%
%We can now print the index:
%To avoid an unwanted coma before the first entry, we print this one first entry separately:
\stepcounter{#1}%
\pageref{#1=\csname the#1\endcsname}%
%Then we run the following as many times as required, i.e. till #1 has reached, here, the value that #1index has reached throughout the document
\whiledo{\NOT\value{#1}=\value{#1index}}%
{%
\stepcounter{#1}%
,
\pageref{#1=\csname the#1\endcsname}%
}%
\smallskip
}
\begin {document}
\IDx {Try}
Text
\newpage
%This paragraph to appear on two pages to illustrate the problem:
\vspace*{43\baselineskip}%
\IDX {Try}
Text textText text

\IDX {Try}

Now I print the index for ‘Try’:
\INDEX{Try}
\end {document}
在此示例中,第 3 页上的条目未被索引,因为命令“thepage”获取了第开始使用该值的段落的值(即此处的第 2 页),而不是人们可能期望的打印页的值(第 3 页)。因此,我的“ifthenelse”检查无法在第 3 页按预期运行。
所以我的问题是:我可以用什么来替换 \thepage 以防止这种情况发生?标签乍一看似乎是解决方案,但我无法用我的参数 #1 定义(还)另一个计数器,无法为每次出现创建(还)另一个标签,也无法使用类似 \pageref{#1-\the#1othercounter} 的内容:这样的引用不起作用。
