gtags

安装GUN global though source code 注意不要用brew安装，因为必须要配置sqlite3

wget http://tamacom.com/global/global-6.5.7.tar.gz
tar xvf global-6.5.7.tar.gz
cd global-6.5.7
./configure --with-sqlite3
make
sudo make install

go get github.com/juntaki/gogtags

在项目目录中输入：
gogtags -v
会生成GTAGS等文件

(use-package helm-gtags
  :config
  (setq helm-gtags-ignore-case t
        helm-gtags-auto-update t
        helm-gtags-use-input-at-cursor t
        helm-gtags-pulse-at-cursor t
        helm-gtags-prefix-key "\C-cg"
        helm-gtags-suggested-key-mapping t)
  :bind (:map helm-gtags-mode-map
              ("C-c g a" . helm-gtags-tags-in-this-function)
              ("C-j" . helm-gtags-select)
              ("M-." . helm-gtags-dwim)
              ("M-," . helm-gtags-pop-stack)
              ("C-c <" . helm-gtags-previous-history)
              ("C-c >" . helm-gtags-next-history))
  :hook ((dired-mode eshell-mode c-mode c++-mode asm-mode) . helm-gtags-mode))

这时候再项目中即可使用
M-x helm-gtags finn partern 等查找tags
