创建标题页：package .sty

Question

我想.sty为标题页创建一个包（）。我遵循了本指南https://en.wikibooks.org/wiki/LaTeX/Title_Creation从中我得到了以下两个代码：第一个代码是名为的包columbidaeTitle.sty，第二个代码是加载先前创建的包的文档。

哥伦比亚Title.sty

文档：

\documentclass{book}
\usepackage{columbidaeTitle}
\supervisor{Dr. James Miller}
\project{Bachelor Thesis}
\author{A LaTeX enthusiast}
\title{Why i want to be a duck}

\begin{document}
\maketitle
\tableofcontents
\chapter{Ducks are awesome}
\end{document}

我有一个问题。我希望整个文档都有这个边距：

\usepackage[bindingoffset=1.5cm, left=3cm, right=3cm, top=3cm, bottom=3cm]{geometry}

除了扉页，我希望

\newgeometry{left=3cm,right=3cm,bottom=2cm,top=3cm}

我尝试插入\RequirePackage{geometry}文件columbidaeTitle.sty然后

\newgeometry{left=3cm,right=3cm,bottom=2cm,top=3cm}
\begin{titlepage}
...
\end{titlepage}
\restoregeometry

但它不起作用。我该怎么做？

Answer 1

只需有条件地加载即可geometry。当然，文档应该明确说明该包必须如果使用此包，则在之后加载geometry。可以添加对此的测试。

columbidaeTitle.sty

输出

如果删除了geometryin的调用，则输出test.tex
