我正在尝试写一篇distill::distill_article需要使用 LaTeX 数学环境的博文，例如定理、引理、证明等。

我已尝试遵循这些说明以及这些说明theorem，但无论使用LaTeX块还是 rmarkdown 块，我都无法渲染环境。

我还注意到，有人问过一个类似的问题distill::distill_article，即专门使用in bookdown。此修复程序也不起作用。请注意，我的用例是在内部使用 bookdown 定理环境distill::distill_article，而不是相反。

这是该问题的代表：

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
library(bookdown)
```

# TL;DR;

Trying to ensure that theorem environments are working in 
`distill::distill_article`.

# Main theorems

With the definitional background established, let's move onto the
main theorem of this article.

\begin{align} 
g(X_{n}) &= g(\theta)+g'({\tilde{\theta}})(X_{n}-\theta) \notag \\
\sqrt{n}[g(X_{n})-g(\theta)] &= g'\left({\tilde{\theta}}\right)
  \sqrt{n}[X_{n}-\theta ] (\#eq:align)
\end{align} 

<!-- # This  does not work, i.e., render in html -->
\begin{theorem}[Delta Method]\label{nthm:deltamethod}
g(X_{n}) &= g(\theta)+g'({\tilde{\theta}})(X_{n}-\theta) \notag \\
\sqrt{n}[g(X_{n})-g(\theta)] &= g'\left({\tilde{\theta}}\right)
  \sqrt{n}[X_{n}-\theta ] (\#eq:align)
\end{theorem} 

<!-- # This reference does not work, i.e., is not recognized -->
We have a labeled and named theorem below, and \@ref(nthm:deltamethod).

<!-- # This  does not work either, i.e., render in html -->
::: {.theorem #pythagoras name="Pythagorean theorem"}
For a right triangle, if $c$ denotes the length of the hypotenuse
and $a$ and $b$ denote the lengths of the other two sides, we have

$$a^2 + b^2 = c^2$$
:::

<!-- # This reference does not work either, i.e., is not recognized -->
We have a labeled and named theorem below, and \@ref(thm:pythagoras).

请注意，我加载bookdown了 rmarkdown，目的是呈现定理环境。但是它不起作用，即不呈现定理或交叉引用。有人可以帮忙解决这个问题吗？

bookdown功能可以使用此处base_format描述的参数与其他单一格式一起使用。

如果所有bookdown的特征都不是 100% 兼容distill格式，那么定理和证明处理应该是。所以这将起作用：

description: |
  Test description

date: 2021-12-31
output:
  bookdown::html_document2:
    self_contained: false
    base_format: distill::distill_article

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```

我没有完成所有这些，但这是引理的一个。这使用了两个类：lemma 和 lemmaS。当您使用类 lemma 时，它会更改整数，当您使用 lemmaS 时，它会增加小数。此方法可应用于所有不同类型的公式块。

更新的样式：

<style>
h1 {
  counter-reset: lemma;
}
h2 {
  counter-reset: lemmaS;
}
.lemma, .lemmaS, .theorem { /* updated to add two types of lemma */
  display: block;
  font-style: italic;
}
.lemma:first-of-type::before, 
.lemmaS:first-of-type::before {
  counter-set: lemma 1;
}
.theorem::before{
  content:"Theorem. ";
  font-weight: bold; 
  font-style: normal;
}
.theorem[name]::before{
  content: "Theorem (" attr(name) ") ";
}
.lemma::before {    /* This will increment by whole numbers: 1, 2, 3 */
  counter-increment: lemma; 
  content: "Lemma " counter(lemma) "." counter(lemmaS);
  font-weight: bold;
  font-style: normal;
}
.lemmaS::before {   /* This will increment by decimals numbers: 2.1, 2.2 */
  counter-increment: lemmaS;
  content: "Lemma " counter(lemma) "." counter(lemmaS) " ";
  font-weight: bold;
  font-style: normal;
}
</style>

代码，使用h1或#重置整数；<h2>或##重置小数点。

# TL;DR;

::: {.theorem name="Pythagorean theorem"}

在我打字的时候看着这个，我想到了一些可以让这个更干净的方法......但我只是想让它在那里工作！我确信有一种方法只使用一类引理，使用标题来表示何时增加整数。无论哪种方式，这都应该让你有其他选择。如果您不想要数字，请使用定理设置，只需将单词 theorem 更改为您想要查看的单词。如果要对它们进行编号，请将单词 lemma 更改为要出现的单词。如果您想要以上所有内容，请在 CSS 中附加名称。

例如，要使用编号，但添加推论 - 您可以在不使用“内容”一词的地方附加，在使用“内容”的地方，复制并更改该词：

.corrolary, 
.lemma, 
.lemmaS, 
.theorem {    /* updated to add two types of lemma */
  display: block;
  font-style: italic;
}
.corollary::before{. /* Copy of .theorem, updated for Corollary */
  content:"Corollary. ";
  font-weight: bold; 
  font-style: normal;
}

如果您希望能够通过超链接引用该定理，您可以使用href，如下所示：

如果你想参考你的定理，你可以这样做。考虑到<a href="#Pythagorean theorem">勾股定理</a>，应该有办法把它联系起来。
