Emacs初始化为org文件：如何获得正确版本的org-mode？

Question

我一直在试验org-babel教程 ，该教程描述了如何将大量emacs init.el文件放入组织文件中。 但是，我想使用org-mode 8（主要用于新的导出器），而且我在内置org-mode 7.9的gnu emacs 24.3.1（对于windows），所以我安装了org-mode来自elpa包管理器而不是使用内置版本。

我的问题是，emacs加载了emacs附带的组织模式，而不是我在elpa中安装的组织模式。 有没有办法加载elpa组织模式？

这是我的init.el，从org-babel教程改为指向（我认为）到我的org-mode发行版 - 但我的emacs-lisp知识很少，所以我真的不知道它在做什么。

;;; From http://orgmode.org/worg/org-contrib/babel/intro.html#literate-programming
;;; init.el --- Where all the magic begins
;;
;; This file loads Org-mode and then loads the rest of our Emacs initialization from Emacs lisp
;; embedded in literate Org-mode files.
;; Load up Org Mode and (now included) Org Babel for elisp embedded in Org Mode files
(setq dotfiles-dir (file-name-directory (or (buffer-file-name) load-file-name)))
(let* ((org-dir (expand-file-name
             "elpa" (expand-file-name
                     "org-plus-contrib-20130624" )))
  (org-contrib-dir (expand-file-name
                     "lisp" (expand-file-name
                             "contrib" (expand-file-name
                                        ".." org-dir))))
       (load-path (append (list org-dir org-contrib-dir)
                      (or load-path nil))))
  ;; load up Org-mode and Org-babel
  (require 'org-install)
  (require 'ob-tangle))

;; load up all literate org-mode files in this directory
(mapc #'org-babel-load-file (directory-files dotfiles-dir t "\\.org$"))

;;; init.el ends here

Answer 1

在调用org-babel-load-file或任何其他Org函数之前放(package-initialize) ，你就会得到ELPA版本。

Answer 2

我使用相同类型的初始化，最近做了两个主要的更改：

• 更改为基于https://github.com/dimitri/el-get的包装管理
• 升级到org-mode> 8.0

这是我的init.el现在的样子，

https://github.com/d4gg4d/my-emacs/blob/master/init.el

也，

• 我删除了随ubuntu一起提供的.deb打包的org-mode

Answer 3

我也在基于组织的配置文件中配置软件包存储库，因此，在加载org之前调整我的init.el中的加载路径：

;; remove org-mode shipped with emacs from the load-path
(setq custom-org-path (car (file-expand-wildcards
                            (concat my-init-dir "elpa/org-plus-contrib-20*")))) 
(when custom-org-path 
  (setq load-path (remove-if (lambda (x) (string-match-p "org$" x)) load-path))

  (add-to-list 'load-path custom-org-path))

Answer 4

虽然已经解决了并且只是有些相关，但我想我会为那些不使用基于包的解决方案但需要卸载org和cedet / semantic等内容而不重新启动emacs的人提供此功能。

一般来说，基于起始名称regexp卸载一组功能，我会做这样的事情 - 这似乎比安德烈亚斯答案的硬编码版本更完整，这似乎并不涵盖所有加载的组织功能（至少在我的情况）。

load-history是一个庞大的文件关联列表 - > reqs，provide，defuns，...

(mapc
 #'(lambda (f) (and (featurep f) (unload-feature f t)))
 (loop for file-syms in load-history
       for prov = (assoc 'provide file-syms)
       with features
       if (and prov (string-match "^org" (symbol-name (cdr prov)))) 
       collect (cdr prov) into features
       finally return features))

替换正则表达式"^org"以满足您的需求，或者去狂野并使它成为一个defun。

还可以修改此选项以从load-history获取所有已加载的组织功能，卸载它们，添加新的加载路径，并从新位置重新加载这些相同的功能。

以这种方式卸载已发布的org-mode和已安装的开发版本

(ar-load-PATH-TO-NEW-org-mode)

将PATH-TO-NEW-org-mode替换为您所使用的版本所在的目录。
