emacs - 在组织模式下，如何为 LaTeX 和 HTML 指定不同的导出选项？

Question

在组织模式下，我想为不同的导出类型指定不同的导出选项，即用于导出到 LaTeX/PDF 的编号标题和目录，用于导出到 HTML 的没有编号和目录。

是否可以在不必每次手动编辑导出选项的情况下执行此操作？

在 ox.el (组织模式的通用导出引擎)有一个过滤系统:

Filters allow end-users to tweak easily the transcoded output. They are the functional counterpart of hooks, as every filter in a set is applied to the return value of the previous one.

其中一个过滤器是 :filter-options :

`:filter-options' applies to the property list containing export
options.  Unlike to other filters, functions in this list accept
two arguments instead of three: the property list containing
export options and the back-end.  Users can set its value through
`org-export-filter-options-functions' variable.

这意味着您可以定义一个类似于此的函数:

(defun my-org-export-change-options (plist backend)
  (cond 
    ((equal backend 'html)
     (plist-put plist :with-toc nil)
     (plist-put plist :section-numbers nil))
    ((equal backend 'latex)
     (plist-put plist :with-toc t)
     (plist-put plist :section-numbers t)))
  plist)

并将其添加到导出过滤器中:

(add-to-list 'org-export-filter-options-functions 'my-org-export-change-options)

该函数将由导出调用，并根据后端将启用或禁用目录/节编号。
