简历中使用的变量的基本定义

Question

我正在用 LaTeX 编写简历，希望实现一些命令来自动化章节样式（尽管我绝不打算编写整个类）。例如，我想在序言中包含一些用于联系信息的简单命令，然后我可以使用这些命令来构建页眉。理想情况下它看起来像这样（我已将其包含resume_config.tex在本文底部）：

% =============================================================================
%                                   Preamble
% =============================================================================
% Checks for correct LaTeX usage (no out of data packages, poor syntax etc.)
\RequirePackage[l2tabu,orthodox]{nag}
% -----------------------------------------------------------------------------
\documentclass[letterpaper,11pt]{article}
\input{resume_config.tex}

% =============================================================================
%                                    Inputs
% =============================================================================
\name{C. Gonzalez}
\email{[email protected]}
\address{000 E 0th St, Austin, TX 12345}
\phone{[phone]}

% =============================================================================
%                                     Body
% =============================================================================
\begin{document}
\makeheader
% \input{resume_education.tex}
% \input{resume_publications.tex}
\input{resume_experience.tex}
% \input{resume_coursework.tex}
% \input{resume_technical.tex}
% \input{resume_other.tex}
\end{document}

我一直在研究模板的 .cls 文件（awesome-cv），发现他们似乎使用以下代码实现了这种事情：

% Define writer's address
% Usage: \address{<address>}
\newcommand*{\address}[1]{\def\@address{#1}}

我的问题是，这段代码到底是什么意思？ 第一的，从我读过的内容来看，这听起来和\def是同一件事\newcommand*，不是吗？ 第二，是\@varname{#1}定义变量的语法，如\@varname = #1？我在 tex.stackexchange 的其他地方读过，但似乎无法弄清楚它到底\@是用来做什么的。 第三，编译器似乎不喜欢我之前使用这些命令\begin{document}，但我不确定这是否相关......

综上所述，对于我的使用来说，只需在“输入”部分写入以下内容是否相同？

\def\@name{C. Gonzalez}
\def\@email{[email protected]}
\def\@address{000 E 0th St, Austin, TX 12345}
\def\@phone{[phone]}

恢复配置.tex：
