給我自己的物品貼上標籤

Question

我正在用latex寫一份小型財務報告...整個報告中有幾個expenses經常重複的內容，例如food，，，等等hotels。train tickets

例如，我第一次寫 時food，我可以在文件food中寫一個靠近它的標籤tex（例如\labelexpenses{food}）；當我寫的時候hotels，我就寫\labelexpenses{hotels}在它旁邊。然後，透過Expense~\refexpenses{food}在 tex 檔案中編寫類似的內容，它可以在 pdf 中顯示Expense 1；Expense~\refexpenses{hotels}在 tex 檔中生成Expense 2.數字1和2由系統產生。

所以它與\label{...}和非常相似\ref{...}，但保留為我可以自己定義的東西，並且數字將由系統自動生成。

有誰知道如何實現這一點？

Answer 1

我猜你的意思是這樣的：

\documentclass{article}
\usepackage{hyperref}
\newcounter{refexp}
\setcounter{refexp}{0}

\newcommand{\labelexpenses}[1]{%
  \phantomsection
  \refstepcounter{refexp}%
  \label{#1}%
}

\newcommand{\refexpenses}[1]{%
  \ref{#1}%
}


\begin{document}

For instance, the first time I write food, I can write a label food
close to it in the tex file (for example
\verb|\labelexpenses{food}|\labelexpenses{food}); when I write hotels,
I write \verb|\labelexpenses{hotels}|\labelexpenses{hotels} next to it. 

Then later, by writing something like Expense~\refexpenses{food} in the 
tex file, it could show in the pdf Expense 1; Expense~\refexpenses{hotels} 
in the tex file generates Expense 2. The numbers 1 and 2 are generated by 
the system.

\end{document}

Answer 2

這是另一個雖然相似的選項：

\documentclass{article}

\usepackage{booktabs}

\newcounter{expensecntr}
\renewcommand{\theexpensecntr}{(\arabic{expensecntr})}
\newcommand{\labelexpense}[1]{%
  \refstepcounter{expensecntr}%
  \label{expense:#1}%
  #1~\theexpensecntr}
\newcommand{\refexpense}[1]{\ref{expense:#1}}

\begin{document}

\begin{tabular}{lr}
  \toprule
  \textbf{Expense} & \textbf{Total} \\
  \midrule
  \labelexpense{Food}  & abc \\
  \labelexpense{Hotel} & def \\
  \labelexpense{Gas}   & ghi \\
  \bottomrule
\end{tabular}

Expense~\refexpense{Hotel} is really expensive.

\end{document}

Answer 3

這就是我過去做類似事情的方式：

\documentclass{article}
\usepackage{etoolbox}
\usepackage{hyperref}

\makeatletter
% save text as a \ref-erencable reference in the auxfile
% usage: \labelledText{label}{text}  --> \ref{label} recalls it
\newrobustcmd{\labelledText}[2]{#2\edef\@currentlabel{#2}\label{#1}}
\makeatother

\begin{document}

    Here is something that I want to refer to later
    \labelledText{later}{101}

    And here I go using \ref{later} again.

    \newcounter{test}

    Saving test to none: \labelledText{none}{\thetest}.

    \addtocounter{test}5

    Saving test to five: \labelledText{five}{\thetest}.

    Using the saved values of none=\ref{none} and five=\ref{five}.

\end{document}

這是輸出：

因此，您可以使用\labelledText{mylabel}{some text}列印some text並為其指派標籤mylabel。之後您可以用來\ref{mylabel}重新列印結果。

無論有沒有 out 都可以使用超引用。
