在org-mode中定义自己的标签

Question

在组织模式中#+AUTHOR或#+LATEX组织中有标签- 它们被称为标签吗？我想定义我自己的标签,它调用一个函数来预处理数据,然后输出它 - 如果导出目标是LaTeX.

Answer 1

我的解决方案是qtree为SRC块定义一种自己的语言.

#+BEGIN_SRC qtree
[.CP [.TP [.NP [] [.N' [.N Syntax] []]] [.VP [] [.V' [.V sucks] []]]]]
#+END_SRC

并相应地处理它.我甚至添加了一个qtree模式paredit.landscape如果树长大,还有一个参数.https://github.com/Tass/emacs-starter-kit/blob/master/vendor/assorted/org-babel-qtree.el

(require 'org)

(defun org-babel-execute:qtree (body params)
  "Reformat a block of lisp-edited tree to one tikz-qtree likes."
  (let (( tree
          (concat "\\begin{tikzpicture}
\\tikzset{every tree node/.style={align=center, anchor=north}}

                  (replace-regexp-in-string
                   " \\_<\\w+\\_>" (lambda (x) (concat "\\\\\\\\" (substring x 1))) 
                   (replace-regexp-in-string
                    (regexp-quote "]") " ]" ; qtree needs a space
                                        ; before every closing
                                        ; bracket.
                    (replace-regexp-in-string
                     (regexp-quote "[]") "[.{}]" body)) ; empty leaf
