关于公司模式和Yasnippet之间干扰的修复

Question

Emacs维基说:

公司确实干扰了Yasnippet的本土行为.这是一个快速修复:http: //gist.github.com/265010

代码如下:

(define-key company-active-map "\t" 'company-yasnippet-or-completion)

(defun company-yasnippet-or-completion ()
  (interactive)
  (if (yas/expansion-at-point)
      (progn (company-abort)
             (yas/expand))
    (company-complete-common)))

(defun yas/expansion-at-point ()
  "Tested with v0.6.1. Extracted from `yas/expand-1'"
    (first (yas/current-key)))

我将该代码放在我的.emacs中,并显示以下消息:

Warning (initialization): An error occurred while loading `c:/Documents and Settings/Alex.AUTOINSTALL.001/Application Data/.emacs.elc':

Symbol's value as variable is void: company-active-map

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the `--debug-init' option to view a complete error backtrace.

我是否必须将修复代码放在YASnippet的.el文件中？或者在我的.emacs中(这会引发错误)？

Answer 1

无论如何，您提到的代码段不再有效。

这是您可以使用的代码段：

(defun company-yasnippet-or-completion ()
  (interactive)
  (let ((yas-fallback-behavior nil))
    (unless (yas-expand)
      (call-interactively #'company-complete-common))))

要确保调用 this 而不是company-complete-common，请使用

(add-hook 'company-mode-hook (lambda ()
  (substitute-key-definition 'company-complete-common
                             'company-yasnippet-or-completion
                             company-active-map)))

背景：这会在本地更改 的值yas-fallback-behaviour，company-complete-common如果未找到完成，则会导致 yas 调用。

这听起来像是加载路径的问题。符号值为 void 意味着 emacs 找不到它的定义 - 很可能是因为包含其定义的文件尚未加载。

您可以尝试在 .emacs 中添加类似的内容（在导致错误的代码之前）：

;; where ~/.emacs.d/ is the path to a directory containing
;; additional library code you want emacs to load
(add-to-list 'load-path "~/.emacs.d/")
