缩小列表中的字体大小

Question

我正在使用 latex beamer，并尝试减小列表的字体大小以显示整个 JSON 代码，而不减小之前句子的字体大小。我该如何让它工作？

代码：

\documentclass[xcolor=dvipsnames]{beamer}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[english]{babel}
\usetheme{Antibes}
\usecolortheme[named=Maroon]{structure} 
\setbeamercovered{transparent}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\usepackage{xcolor}
\usepackage{listings}

\newcommand\JSONnumbervaluestyle{\color{red}}
\newcommand\JSONstringvaluestyle{\color{red}}

% switch used as state variable
\newif\ifcolonfoundonthisline

\makeatletter

\lstdefinestyle{json}
{
  showstringspaces    = false,
  alsoletter          = 0123456789.,
  morestring          = [s]{"}{"},
  stringstyle         = \ifcolonfoundonthisline\JSONstringvaluestyle\fi,
  MoreSelectCharTable =%
    \lst@DefSaveDef{`:}\colon@json{\processColon@json},
  basicstyle          = \ttfamily,
  keywordstyle        = \ttfamily\bfseries,
}

% flip the switch if a colon is found in Pmode
\newcommand\processColon@json{%
  \colon@json%
  \ifnum\lst@mode=\lst@Pmode%
    \global\colonfoundonthislinetrue%
  \fi
}

\lst@AddToHook{Output}{%
  \ifcolonfoundonthisline%
    \ifnum\lst@mode=\lst@Pmode%
      \def\lst@thestyle{\JSONnumbervaluestyle}%
    \fi
  \fi
  %override by keyword style if a keyword is detected!
  \lsthk@DetectKeywords% 
}

% reset the switch at the end of line
\lst@AddToHook{EOL}%
  {\global\colonfoundonthislinefalse}

Answer 1

只需将字体大小添加到基本样式中，例如，

basicstyle = \ttfamily\small,

当然，有了这么大的缩进，你就需要更小的字体了：

如果你

\begin{lstlisting}[style=json,basicstyle=\ttfamily\tiny]
        [{"stops": [{
                     "arrival_time": {
                                       "mon-fri": [ "04:31", "04:43"],
                                      "sat":     ["05:32", "06:32"],
                                      "sun":     ["05:32", "06:32"]
                                      },
                     "stop_name": "XYZ",
                     "stop_lat": "90.874136",
                     "stop_long": "19.665553"
                    }]
         }]
\end{lstlisting}
