\section{引言}

\pkg{circledtext}是一个基于\pkg{l3draw}用\pkg{expl3}开发的
排版带圈文字的宏包，它提供了唯一的一个排版命令\tn{circledtext}%
用于对其必选参数中的文本按指定的基字符大小缩放后，再为其添加
圆形边框，然后排版输出。其带星号``*''命令\tn{circledtext*}用于
实现反色阴文排版输出。可以通过该命令的命令选项或\tn{circledtextset}%
命令设置排版输出的不同外观。

\section{用户接口}

\subsection{\cs{circledtext}排版命令}

\begin{function}{\circledtext}
  \begin{syntax}
    \cs{circledtext} \oarg{外观选项} \marg{文本}
  \end{syntax}
\end{function}

  按设置的\oarg{外观选项}对指定的\marg{文本}添加圆圈后排版输出。

  该命令仅有一个必选参数\marg{文本}，用于指定需要排版的文本。

  在\oarg{外观选项}中可以通过key-value的方式设置颜色、字体、字号、线宽等外观。

  外观也可以通过\cs{circledtextset}命令，以逗号分隔key-value列表进行设置。

  通过\oarg{外观选项}设置的外观参数仅对当前命令局部有效，
  通过\cs{circledtextset}命令设置的外观参数对后续所有命令有效。

  其星号版本命令用于反色阴文输出。

\subsection{\cs{circledtextset}外观选项设置命令}

\begin{function}{\circledtextset}
  \begin{syntax}
    \cs{circledtextset} \marg{外观选项}
  \end{syntax}
\end{function}

  用于设置外围圆圈及文本的外观。

  在\marg{外观选项}中可以通过key-value方式设置颜色、
  字体、字号、线宽等外观。

  通过\cs{circledtextset}命令设置的外观参数对后续所有命令有效。

\section{Introduction}

\pkg{circledtext} is a text with circle package based on%
\pkg{l3draw} by \pkg{expl3}. This package provides a macro
\tn{circledtext} to create arbitrary ``circled'' text. The 
starred macro can create negative ``circled'' text.
a macro \tn{circledtextset} to set the format of ``circled''
text.

\section{Inerface}

\subsection{\cs{circledtext} macro}

\begin{function}{\circledtext}
  \begin{syntax}
    \cs{circledtext} \oarg{options} \marg{text}
  \end{syntax}
\end{function}

  According to \oarg{options} to create ``circled''
  \marg{text}.

  \oarg{options} are key-value for color, font, size and so on.。

  Macro's \oarg{options} are local setting.

  If global settings are needed, the \cs{circledtextset} macro is required.

  The starred version can create negative ``circled'' text.

\begin{SideBySideExample}[frame=single,numbers=left,xrightmargin=.45\linewidth,gobble=2]
  \centering
  \circledtext{8}\quad
  \circledtext{888}\quad
  \circledtext*{8}\quad
  \circledtext*{888}
\end{SideBySideExample}
\subsection{\cs{circledtextset} macro}

\begin{function}{\circledtextset}
  \begin{syntax}
    \cs{circledtextset} \marg{options}
  \end{syntax}
\end{function}

  Used to set the appearance of ``circled'' text.

  In \marg{options} you can set the appearance of the 
  color, font, size, linewidth, etc. by key-value lists.

  The appearance seted by the \cs{circledtextset} are 
  valid for all subsequent macros.

\section{options}

\begin{option}{ opt = basechar, desc = {= \meta{base char}}, init=好/x }
  Set size measurement base character. If compiled with xetex or luatex engine,
  the initial value is ``好'' in Chinese, otherwise the initial value is the 
  letter ``x'' in English.
