为 lstnewenvironment 提供文档输入

Question

我最近问了这个问题：不同列表语言脚本的独立标题和编号

而我需要的答案是使用\lstnewenvironment。问题是我仍在处理代码，所以我需要导入代码。我以前使用过\lstinputlisting，但它似乎与不兼容\lstnewenvironment。

有没有办法将输入文档提供给\lstnewenvironment就像那样\lstinputlisting？

我尝试了这个，但没有成功：

\documentclass{extarticle}
\usepackage{listings}

\newcounter{pythoncode}
\lstnewenvironment{pythoncode}[3]{
    \renewcommand\lstlistingname{Python Code}
    \setcounter{lstlisting}{\value{pythoncode}}
    \lstset{
        frame=single,   
        language=python,
        rulecolor=\color{black},
        commentstyle=\color{mGreen},
        keywordstyle=\color{mOrange},
        caption={[#1]{#1}},
        label={#2},    
        inputpath={#3}    
    }
} {\addtocounter{pythoncode}{1}}

\begin{document}

    \begin{pythoncode}{someCaption}{someLabel}{patronesOptimos.py}
    \end{pythoncode}

\end{document}

输出是这样的（当然它不是一个空的 Python 文件）：

我也尝试过这个，但它会产生超时：

\documentclass{extarticle}
\usepackage{listings}

\lstdefinestyle{mypy}{
        frame=single,   
        language=python,
        rulecolor=\color{black},
        commentstyle=\color{mGreen},
        keywordstyle=\color{mOrange},
}

\newcounter{pythoncode}
\lstnewenvironment{pythoncode}[3]{
    \renewcommand\lstlistingname{Python Code}
    \setcounter{lstlisting}{\value{pythoncode}}
    \lstset{
        escapeinside={(*@}{@*)},
        caption={[#1]{#1}},
        label={#2}
    }
} {\addtocounter{pythoncode}{1}}

\begin{document}

    \begin{pythoncode}{someCaption}{someLabel}
        (*@
        \lstinputlisting[style = mypy]{Codigos/patronesOptimos.py}
        @*)
    \end{pythoncode}

\end{document}

你不想要环境。

\begin{filecontents*}{\jobname.py}
print("Hello, World!")
\end{filecontents*}
\begin{filecontents*}{\jobname.run}
model cut.mod;
data cut.dat;
option solver cplex, solution_round 6;
option display_1col 0, display_transpose -10;

problem Cutting_Opt: Cut, Number, Fill;
option relax_integrality 1;

problem Pattern_Gen: Use, Reduced_Cost, Width_Limit;
option relax_integrality 0;

let nPAT := 0;
for {i in WIDTHS} {
   let nPAT := nPAT + 1;
   let nbr[i,nPAT] := floor (roll_width/i);
   let {i2 in WIDTHS: i2 <> i} nbr[i2,nPAT] := 0;
}

repeat {
   solve Cutting_Opt;
   let {i in WIDTHS} price[i] := Fill[i].dual;

   solve Pattern_Gen;
   if Reduced_Cost < -0.00001 then {
      let nPAT := nPAT + 1;
      let {i in WIDTHS} nbr[i,nPAT] := Use[i];
   }
   else break;
}
display nbr, Cut;

option Cutting_Opt.relax_integrality 0;
solve Cutting_Opt;
display Cut;
\end{filecontents*}

\documentclass{article}
\usepackage{listings}
\usepackage{xcolor}
\usepackage{newfloat}

\colorlet{mGreen}{green!65!blue}
\colorlet{mOrange}{red!50!green}
\colorlet{mGray}{black!60}
\colorlet{mPurple}{red!70!blue}

\newcommand{\genericcode}[3]{%
  % #1 = language (long), #2 = language (short), #3 = style to load
  \DeclareFloatingEnvironment[placement={!htp},name=#1 code]{#1Float}%
  \expandafter\newcommand\csname #2code\endcsname[3]{%
    \begin{#1Float}
    \lstset{style=#3,columns=fullflexible}% <-- I can't stand the default
    \lstinputlisting{##3}%
    \caption{##1}\label{##2}
    \end{#1Float}
  }%
}
\genericcode{Python}{python}{mypy}
\genericcode{AMPL}{ampl}{StyleAMPL}

% You can now use e.g. \counterwithin in the following fashion
\counterwithin{PythonFloat}{section}

\lstdefinestyle{mypy}{
  frame=single,   
  language=python,
  rulecolor=\color{black},
  commentstyle=\color{mGreen},
  keywordstyle=\color{mOrange},
}

\lstdefinestyle{StyleAMPL}{  
  frame=single,   
  rulecolor=\color{black},
  commentstyle=\color{mGreen},
  keywordstyle=\color{magenta},
  numberstyle=\tiny\color{mGray},
  stringstyle=\color{mPurple},
  basicstyle=\footnotesize,           
  showstringspaces=false,
  showtabs=false,                  
  tabsize=3,
%  language=AMPL,
}

\begin{document}
\section{Gives us a section number}
\pythoncode{Caption with section number}{PyLabel}{\jobname.py}

\amplcode{Caption without section number}{AMPLLabel}{\jobname.run}

\end{document}

笔记。我注释掉了，language=AMPL因为我不知道应该如何定义它。我还添加了columns=fullflexible，因为我总是对按列对齐的可变大小字符列表感到恐惧。

Answer 2

找到了！我还在处理细节问题，但主要问题已经解决了。

\lstinputlisting解决方案是使用在内部创建一个新的浮动环境usepackage{newfloat}。

我只需要找出如何[h!]在新的浮动环境中添加放置参数。

\documentclass{article
\usepackage{listings}
\usepackage{newfloat}

\input{colors.tex} % mOrange, mGreen and so
\input{AMPL.tex} % where is \lstdefinelanguage{AMPL}{...}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% defining the styles
\lstdefinestyle{mypy}{
        frame=single,   
        language=python,
        rulecolor=\color{black},
        commentstyle=\color{mGreen},
        keywordstyle=\color{mOrange},
}

\lstdefinestyle{StyleAMPL}{  
    frame=single,   
    rulecolor=\color{black},
    commentstyle=\color{mGreen},
    keywordstyle=\color{magenta},
    numberstyle=\tiny\color{mGray},
    stringstyle=\color{mPurple},
    basicstyle=\footnotesize,           
    showstringspaces=false,
    showtabs=false,                  
    tabsize=3,
    language=AMPL
}
