带有外文数字的 tikz 日历

Question

我想用多语种的梵文数字表示日期数字。后者提供了\devanagaridigits{}数字转换功能，但简单地执行\devanagaridigits{\tikzdaytext}此\pgfkeys{/tikz/day code= {...}}操作不起作用。

这是我的妈妈：

\documentclass{beamer}

\mode<presentation>
{    \usetheme{metropolis}    }

\geometry{verbose,papersize={160mm,90mm}}

\usepackage{fontsize,fix-cm}

\usepackage{polyglossia}
\newfontfamily\devanagarifontsf[Script=Devanagari]{NotoSansDevanagari}

\setmainlanguage{sanskrit}
\setmainfont[Script=Devanagari]{NotoSansDevanagari}
 
\usepackage{tikz}
\usetikzlibrary{calendar,fit}

\pgfkeys{/tikz/day code =
  {
    \node (lower right) at (0,0) [above left,font=\large] {
      \tikzdaytext};  
% here \devanagaridigits{\tikzdaytext} is not working

    \node (upper left) at (-\cellwidth,\cellheight)
    [below right,align=left,text width=\cellwidth-\pgflinewidth,
    font=\tiny,black] {};
    \node (lower left) at (-\cellwidth,0) {};
    \node[rounded corners, draw,
          fit=(lower right) (upper left) (lower left),
          inner sep=1mm] {};
  }
}

\pgfkeys{/tikz/inner sep = 0pt}
\pgfkeys{/tikz/day xshift=\cellwidth+2mm+2mm}
\pgfkeys{/tikz/day yshift=\cellheight+2mm+2mm}

\newlength{\cellheight}
\setlength{\cellheight}{5mm}
\newlength{\cellwidth}
\setlength{\cellwidth}{7mm}

\begin{document}
\begin{frame}{दिनदर्शिका}

  \begin{tikzpicture}
    \calendar (mycal) [dates=\year-10-29 to \year-11-2,
    day list right];
  \end{tikzpicture}

\end{frame}
\end{document}

Answer 1

默认\tikzdaytext值为速记 \%d-（最短表示，即没有前导零）默认情况下不可扩展。

您需要使用

• \%d0或者\pgfcalendarcurrentday，一个只包含日期数字但带有前导零的宏，或者
• \number\%d0\relax将数字转换为失去前导零的数字。

在第一种情况下，我们需要\%d0适当扩展（实际上是两次）

\expandafter\devanagaridigits\expanded{{\%d0}}

但我们不需要它\pgfcalendarcurrentday。
