如何在 Latex 的新命令中添加空行
我正在使用以下使用 \newcommand （宏）的代码：
\documentclass[12pt]{article}
\usepackage{color}
\usepackage{graphicx}
\begin{document}
% definition of new commands:
\newcommand{\mytitle}[1]{\LARGE\color{black}\centering\textbf{#1\newline}}
% NEWLINE WORKS IN ABOVE LINE
\newcommand{\mycode}{\small\color{green}Code:\scriptsize\leftskip30pt\color{red}\\*}%
% CANNOT ADD NEWLINE BEFORE "Code:" IN ABOVE LINE
\newcommand{\mytext}{\normalsize\color{black}\leftskip0pt}
\newcommand{\myoutput}{\small\color{green}Output:\scriptsize\leftskip30pt\color{blue}\\}%
% CANNOT ADD NEWLINE BEFORE "Output:" IN ABOVE LINE
\quote % to prevent indentation of first line;
% main text starts here:
\mytitle{Simple text, code and figure.}
\mytext
This is normal text- part 1.\\
This is normal text- part 1.\\
This is normal text- part 1.\\
\mycode
This is code line 1.\\
This is code line 2.\\
This is code line 3.\\
\myoutput
This is output line 1.\\
This is output line 2.\\
This is output line 3.\\
\mytext
This is normal text- part 2.\\
This is normal text- part 2.\\
This is normal text- part 2.\\
\mycode
This is code part 2.\\
This is code part 2.\\
This is code part 2.\\
\myoutput
This is output part 2.\\
This is output part 2.\\
This is output part 2.\\
\mytext
The last line in normal text.\\
\end{document}
虽然输出没问题，但我无法在“代码：”、“输出”和文本部分之前输入空行：
我尝试使用\\ \newline并\linebreak[1]在箭头标记的点处添加空行，但它们都会产生以下错误：
There's no line here to end.
如何在文本的代码、输出和文本部分之前添加空行？谢谢你的帮助。
