Tmux分屏

• cat ~/.tmux.conf

  set -g default-terminal "screen-256color"
  set -g history-limit 10000
  
  # Easy config reload
  bind r source-file ~/.tmux.conf \; display-message "tmux.conf reloaded"
  bind C-a source-file ~/.tmux/layout/mylayout \; display-message "tmux.conf reloaded"
  
  # Use Alt-arrow keys to switch panes
  unbind-key j
  bind-key j select-pane -D
  unbind-key k
  bind-key k select-pane -U
  unbind-key h
  bind-key h select-pane -L
  unbind-key l
  bind-key l select-pane -R
  
  unbind '"'
  bind - splitw -v -c '#{pane_current_path}' # 垂直方向新增面板，默认进入当前目录
  unbind %
  bind | splitw -h -c '#{pane_current_path}' # 水平方向新增面板，默认进入当前目录

Vim Ctags

• sudo apt-get install vim universal-ctags
• make ARCH=arm tags
  • 要等得挺久才行
• cat ~/.vimrc

  set mouse-=a
  
  syntax on
  set hlsearch
  hi Search ctermbg=white
  hi Search ctermfg=black
  
  set tabstop=4
  set shiftwidth=4
  "set expandtab
  
  set tags+=/home/pi/zengjf/linux-rpi-5.4.y/tags

Vim Cscope

• sudo apt-get install cscope
• make ARCH=arm cscope
• ls cscope*
• cat ~/.vimrc

  set mouse-=a
  syntax on
  set hlsearch
  hi Search ctermbg=white
  hi Search ctermfg=black
  
  set tags+=/home/pi/zengjf/linux-rpi-5.4.y/tags

  • s: 查找C语言符号，即查找函数名、宏、枚举值等出现的地方
  • g: 查找函数、宏、枚举等定义的位置，类似ctags所提供的功能
  • d: 查找本函数调用的函数
  • c: 查找调用本函数的函数
  • t: 查找指定的字符串
  • e: 查找egrep模式，相当于egrep功能，但查找速度快多了
  • f: 查找并打开文件，类似vim的find功能
  • i: 查找包含本文件的文
