我可以看一下纯 TeX 源文件吗？

我可以看一下纯 TeX 源文件吗？

所有 LaTeX 教程都告诉我 LaTeX 是一个简化 TeX 文档构建的扩展。可以理解的是，现在没有人再使用纯 TeX 了，对吧？

但当我掌握了 TeX 和 LaTeX 之间的联系后，我似乎学得更好了。有人有纯 TeX 示例文件的链接吗？我想知道哪些命令、宏等是特定于 LaTeX 的。

以下是一个例子：

The reconstruction conjecture states that the multiset of unlabeled

由于 TH 抓住机会发布了 xii.tex，我也抓住机会发布了我的进一步精简版本（相同输出所需的击键次数减少了近 14% :-)）。这次练习确实是我第一次深入研究 TeX 的内部工作原理。

答案3

有许多纯 TeX 源文件的示例。例如，我的所有书籍和文章都是用纯 TeX 编写的：

这里有一个用纯 TeX 编写的学士论文示例（包括来源）：

纯 TeX 无法分离 逻辑标记从排版任务我和我的学生始终尊重这条规则。例如，您可以在所提及的学士论文来源中验证这一点。

不幸的是，这不是一个好的例子，因为这里的排版宏和文本混在一起了。文档内部texbook.tex有，等等。\def's\eject

您可以创建糟糕的文档（其中排版任务与逻辑标记混合）或好的文档，而基本使用的宏是纯 TeX 或 LaTeX。从这个角度来看，这里接受的答案是坏例子在纯 TeX 中这是很好的做法，因为在文档的作者部分里面有\bigskip\bigskip， 等等。\centerline \indent

最后，我不同意 David Carlisle 的例子是纯 TeX 的典型例子。这只是 TeX 功能的一个例子。纯 TeX 与它没有任何共同之处。您可以创建以下文档：

并用 LaTeX 处理。你会说这是典型的 LaTeX 文档吗？

编辑我将展示与此处 (Sadeq) 接受的答案中相同的示例，但将部分分开：宏和作者的文本。作者可以是宏的程序员以外的其他人。

文本作者创建的纯 TeX 文件将是：
