datatool 包未读取 csv 文件

Question

您的示例中的一些材料与每页打印引文的问题并不严格相关，因此我将其删除。但您可以使用包everypage来datatool执行您想要的操作。类似这样的操作将不断循环显示中的 11 条引文，.csv并在底部打印一条：

\begin{filecontents}{quotations.csv}
I\space think everybody in this country should learn how to program a computer because it teaches you how to think.; Steve Jobs
Computer Science is no more about computers than astronomy is about telescopes.; Edsger W. Dijkstra
The computer was born to solve problems that did not exist before.; Bill Gates
A\space computer would deserve to be called intelligent if it could deceive a human into believing that it was human.; Alan Turing

Imagination is more important than knowledge.  For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution.; Albert Einstein

需要注意的事项：

目前，在使用的页面上没有打印引文\chapter。我不确定所需的行为是什么。（此外，这些页面仍然“步进”计数器，因此您最终会跳过这些页面上的引文。） 新章节开始的页面上是否也应该有引文？
我将分隔符改为;（参见\DTLsetseparator{;}），因为一些引文本身带有逗号。
由于某种我还没有探究过的原因，当引文以一个字母的单词（例如“I”或“A”）开头时，它与后面的单词之间的空格就会丢失。（参见第 1、4 和 11 行.csv。）

变化：

现在，每页的底部都使用引文和作者。
留出空间是为了在页脚中放置小图像。（目前，我已将其设置为绘制一个 2 厘米 x 2 厘米的黑色框。）这需要对页面底部进行适当的设置，geometry并将引文放在为图像留出空间的框中（参见\setquoteandauthor）。
