不備があったので種々修正

Descritpion

• 対象環境

  • Mac Sierra
  • python 2.x.x
  • 対象言語 : ruby / python / go
  • Emacs 24 or higher.
  • helm 1.7.7 or higher (helm設定済みとする)
  • GNU Global 6.2.3 or higher

• helm-gtagとは

  • 関数定義へ M-g などで飛べる (関連箇所の list up)

install

console

# pythonはinstall済みとする
brew install ctags
brew install global --with-exuberant-ctags --with-pygments

tag作成

console

sudo cp /usr/local/share/gtags/gtags.conf /etc/

cd [project root] # gtagを作成するdirへ移動

# gtags -v --gtagslabel=exuberant-ctags --gtagsconf=/usr/local/share/gtags/gtags.conf
gtags -v --gtagslabel=pygments --gtagsconf=/usr/local/share/gtags/gtags.conf
global -x -t ignore_missing

console

# 検索テスト
global -ax -t [関数名]

install emacs package

emacs_packages

# package install
helm-gtags
exec-path-from-shell

init.el

init.el

# 以下書き込み
(exec-path-from-shell-initialize)

(require 'helm-gtags)

;; Enable helm-gtags-mode
(add-hook 'go-mode-hook (lambda () (helm-gtags-mode)))
(add-hook 'python-mode-hook (lambda () (helm-gtags-mode)))
(add-hook 'ruby-mode-hook (lambda () (helm-gtags-mode)))

;; gtag setting
(setq helm-gtags-path-style 'root)
(setq helm-gtags-auto-update t)

;; key bind
(add-hook 'helm-gtags-mode-hook
          '(lambda ()
             (local-set-key (kbd "M-g") 'helm-gtags-dwim)
             (local-set-key (kbd "M-s") 'helm-gtags-show-stack)
             (local-set-key (kbd "M-p") 'helm-gtags-previous-history)
             (local-set-key (kbd "M-n") 'helm-gtags-next-history)))

以上

Jump

• 当該directoryの何らかのfileを開く
• 任意のsymbolの上にカーソルをのせ, M-gで関数定義箇所へ飛ぶ. (もしくは, list up)

補足

tagはfile保存時に自動で再生成される (はず)
