vimrc & tmux 設定

"欸,你都用什麼編輯器?" "小畫家啊"

其實有蠻長一段時間都用sublime text寫code,但不管是在研究所時期或是現在工作以後,幾乎都需要連線到遠端開發機作業,即便可以用掛載磁碟的方式在本地端編輯,但若是加個VPN再參雜一些種花點心的網路...

恩,就這樣我又回到vim的懷抱。以往都直接抓vgod大神的設定檔來改,但你知道改code改到最後都會想說直接重寫還比較快,加上我用到的套件其實不多,所以乾脆自己設定一個。

基本上是使用Vundle這套plug-in manager 來幫我安裝所有的plugin,是我目前使用起來最簡潔的工具了

以下是我的vimrc,可以看得出來基本上是以javascriptreactjs開發為主

	set nocompatible              " be iMproved, required
	filetype off                  " required

	" set the runtime path to include Vundle and initialize
	set rtp+=~/.vim/bundle/Vundle.vim
	call vundle#begin()

	" let Vundle manage Vundle, required
	Plugin 'VundleVim/Vundle.vim'


	Plugin 'rstacruz/sparkup', {'rtp': 'vim/'}
	Plugin 'tpope/vim-fugitive'
	" vim-airline
	Plugin 'vim-airline/vim-airline'
	Plugin 'elzr/vim-json'
	Plugin 'pangloss/vim-javascript'
	Plugin 'mattn/emmet-vim'
	Plugin 'mxw/vim-jsx'

	" All of your Plugins must be added before the following line
	call vundle#end()            " required
	filetype plugin indent on    " required
	" To ignore plugin indent changes, instead use:
	"filetype plugin on
	"
	" Brief help
	" :PluginList       - lists configured plugins
	" :PluginInstall    - installs plugins; append `!` to update or just :PluginUpdate
	" :PluginSearch foo - searches for foo; append `!` to refresh local cache
	" :PluginClean      - confirms removal of unused plugins; append `!` to auto-approve removal
	"
	" see :h vundle for more details or wiki for FAQ
	" Put your non-Plugin stuff after this line
	"
	set nocompatible	" not compatible with the old-fashion vi mode
	set bs=2		" allow backspacing over everything in insert mode
	set history=50		" keep 50 lines of command line history
	set ruler		" show the cursor position all the time
	set autoread		" auto read when file is changed from outside
	set laststatus=2

	syntax on

	let g:airline_powerline_fonts = 1
	let g:airline_theme='solarized'
	syntax enable
	set nu

除此之外,既然要遠端連線工作,總不能每次斷線以後,都要手動重新打開上一次工作階段,並且清除temp file吧!

我們是程式設計師,我們很懶,所以需要更聰明的作法。因此tmux就很重要了!

tmux是什麼呢? 根據官方文件:

*tmux is a terminal multiplexer. It lets you switch easily between several programs in one terminal, detach them (they keep running in the background) and reattach them to a different terminal. And do a lot more. *

看到沒有!

** Detach them (they keep running in the background) and reattach them to a different terminal **

簡單來說,有了tmux,以後連線到遠端VM或是server時,就算在你開著好幾個session並且vim使用中的情況下,網路斷了或是你想拿著筆電去樓下買咖啡,回來時還是可以無痛回到你原先的工作狀態!不會因為連線中斷而需要重新initialize你原先的state。

那要怎麼使用這麼好用的工具呢?

於 Debian / Ubuntu Linux 安裝 Tmux
$ apt-get install tmux

安裝很簡單,接著要編輯tmux.conf,以下是我的設定檔:

	unbind C-b
	set -g prefix ^A
	bind a send-prefix

	# set colors
	set-window-option -g window-status-current-fg blue
	set-window-option -g window-status-current-bg yellow
	set-window-option -g window-status-current-attr default

	# switch to next window
	unbind C-Right
	bind -n C-Right next-window

	# switch to previous window
	unbind C-Left
	bind -n C-Left previous-window

	# split windows like vim
	# vim's definition of a horizontal/vertical split is reversed from tmux's
	bind s split-window -v
	bind v split-window -h

	# move around panes with hjkl, as one would in vim after pressing ctrl-w
	bind h select-pane -L
	bind j select-pane -D
	bind k select-pane -U
	bind l select-pane -R

	# vi-style controls for copy mode
	setw -g mode-keys vi
	unbind [
	bind Escape copy-mode
	unbind p
	bind p paste-buffer
	bind-key -t vi-copy 'v' begin-selection
	bind-key -t vi-copy 'y' copy-selection

	unbind ,
	bind A command-prompt "rename-window '%%'"

好,其實也很多是東抓西抓出來的,所以依照我這份設定檔,我常用的指令大概就是:

  • tmux 進入tmux session
  • tmux attach 在新的terminal (我推薦Iterm2) 重新attach回你之前的工作狀態(先前開啟中的tmux seesion)
  • Crtl + A & C 先按Crtl A,接著按下C,就會開啟一個新的tmux session
  • Crtl + A & Shift+7 其實就是Crtl + A接著按下 & 符號,就可以刪除當前session

用了tmux以後好像世界太平一片祥和風和日麗,但是事情沒有這麼簡單,當你用慣iterms方便的捲軸功能去瀏覽先前的terminal紀錄後,發現開了tmux就捲不上去時可能會很痛苦,不過沒關係,還是有折衷方案!

  • Crtl + A & pageUp or up Arrow 讓你可以往上或往下去terminal紀錄

好的,老實說這篇只是我想記錄一下我的記錄檔案... 所以如果需要好好學習tmux的人,可以移駕 Tsung's Blog
