乳胶环境中组织模式的段落填充 [英] Paragraph filling for org-mode inside latex environment

问题描述

我开始使用组织模式撰写数学论文，因此大量使用了乳胶环境，例如证明，定理，引理等。例如，我经常写

I started using org-mode to write mathematical papers so I make a heavy use of latex environments such as proof, theorem, lemma, etc. For example I often write

\begin{proof}

a very long proof follows

\end{proof}

问题是在组织模式下，填充段（或 Mq ）在乳胶环境中不起作用。这使我的生活变得复杂，因为一些证明可能很长，编译为pdf时会达到几页，而且我无法以org-mode有效地格式化它们。我在手册中找不到有关控制段落填充的选项的任何信息。在这种情况下是否可以启用填充段？

The problem is that in org-mode the fill-paragraph (or M-q) doesn't work inside latex environments. This complicates my life because some proofs can be very long, reaching several pages when compiled to pdf, and I am unable to efficiently format them in org-mode. I couldn't find any information in the manual on options controlling paragraph filling. Is it possible to enable fill-paragraph in this case?

推荐答案

如果您使用组织块而不是乳胶环境，问题就会消失：

The problem disappears if you use an org block instead of a latex environment:

#+BEGIN_proof 
...
#+END_proof 

这将导出为 \begin {proof } ... \end {proof} 。它还可以让您在块内使用org语法，并填充段落。

This gets exported as \begin{proof}...\end{proof}. It also lets you use org syntax inside the block, and fill paragraph works.

如果您不想这样做，可以尝试 visual行模式作为解决方法。

if you don't want to do that, maybe try visual-line-mode as a workaround.

编辑：更改填充段落的行为

如果想让段落在乳胶环境中工作，则必须更深入地研究。填充是通过 org.el 中的 org-fill-paragraph 完成的，默认情况下，此功能会忽略乳胶环境。要更改此设置，请转到函数末尾并替换

If you want fill paragraph to work in latex environments, you have to dig a little deeper. Filling is done by org-fill-paragraph in org.el and this function ignores latex environments by default. To change this, go to the end of the function and replace

  ;; Ignore every other element.
  (otherwise t)

with

  (latex-environment nil) ;; use default fill-paragraph
  ;; Ignore every other element.
  (otherwise t)

如果您不想更改组织来源，则可以请改用建议，例如

If you'd rather not change the org sources, you could use advice instead, e.g.

(defun org-fill-paragraph--latex-environment (&rest args)
  "Use default fill-paragraph in latex environments."
  (not (eql (org-element-type (org-element-context)) 'latex-environment)))

(advice-add 'org-fill-paragraph :before-while #'org-fill-paragraph--latex-environment)
