Question

我是关于emac的新人。我在youtube上关注了emacs的教程，作为c / c ++的ide 但有一些步骤对我来说无法完全发挥作用：c-header的自动完成。

我为C / C ++标题安装了yasnippet并自动完成。

我获得了#include <stdio.h的正常自动完成行为，但即使我在>

上键入标签，也未添加h关闭挂钩

其他人#include <float未使用.h>完成， #include <ctype.h>根据我的要求isdig而不是isdigit来调用

; start package.el with emacs
(require 'package)
;add MELPA to repository list
(add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/"))
;initialize package.el
(package-initialize)
;start auto-complete with emacs
(require 'auto-complete)
;do default config for auto-complete
(require 'auto-complete-config)
(ac-config-default)
;start yasineppet with emacs
(require 'yasnippet)
(yas-global-mode 1)
;let's define a function which initializes auto-complete-c-headers and gets called for c/c++ headers hooks
(defun my:ac-c-header-init ()
  (require 'auto-complete-c-headers)
  (add-to-list 'ac-sources 'ac-source-c-headers)
  (add-to-list 'achead:include-directories '"/usr/include/c++/5
 /usr/include/x86_64-linux-gnu/c++/5
 /usr/include/c++/5/backward
 /usr/lib/gcc/x86_64-linux-gnu/5/include
 /usr/local/include
 /usr/lib/gcc/x86_64-linux-gnu/5/include-fixed
 /usr/include/x86_64-linux-gnu
 /usr/include")
)
;now let's call this function from c/c++ hooks
(add-hook 'c++-mode-hook 'my:ac-c-header-init)
(add-hook 'c-mode-hook 'my:ac-c-header-init)

缺少什么？

我不确定C的配置。但是，我看到你在init文件中使用auto-complete模式。你能试试company-mode吗？在我看来，它比auto-complete模式

更有效

emacs auto-complete-c-headers关闭钩子
