Mac OS Setup

Setting up vim

" You need to import default vim settings first, e.g. syntax highlighting, etc.
source $VIMRUNTIME/defaults.vi

" Set non visual mode when mouse is dragging on vim
set mouse-=a

" set 1 tab == 4 spaces..
filetype plugin indent on
" show existing tab with 4 spaces width
set tabstop=4
" when indenting with '>', use 4 spaces width
set shiftwidth=4
" On pressing tab, insert 4 spaces
set expandtab

run .bashrc at .bash_profile time

if [ -f $HOME/.bashrc ]; then
        source $HOME/.bashrc
fi

• Difference between .bashrc and .bash_profile
  • Basically .bash_profile runs at log-in, .bashrc runs when you run an interactive shell
  • But in Mac OS X, it runs login shell every time (even for starting an interactive shell).

Highlight for git branch name

• Find git-prompt.sh from official git repo
• Setup code example

source ~/.git-prompt.sh
PS1='[\u@\h \W$(__git_ps1 " \[\033[32m\](%s)\[\033[00m\]")]\$ '

Double Pinyin (双拼)

1. 使用Ctrl + space来改变输入法。 Use Ctrl + space to change input source..

2. 使用Karabiner来把Shift键映射为Ctrl + space。Use Karabiner to support using Shift to switch between input sources.

   • 以下为映射代码 （需要放在~/.config/karabiner/karabiner.json，可能需要先做Karabiner UI里面先映射一个simple modification，然后karabiner.json文件才会被创建。）Code to do that (to be put in ~/.config/karabiner/karabiner.json, you may need to set a simple modification first in Karabiner UI, then do this).
   • 更改文件中 complex_modifications => rules 的内容。You need to change the complex_modifications => rules as follows:

                     "rules": [
                      {
                       "manipulators": [
                           {
                               "description": "Change left_shift to control+space when used alone",
                               "from": {
                                   "key_code": "left_shift",
                                   "modifiers": {
                                       "optional": [
                                           "any"
                                       ]
                                   }
                               },
                               "to": [
                                   {
                                       "key_code": "left_shift"
                                   }
                               ],
                               "to_if_alone": [
                                   {
                                       "key_code": "spacebar",
                                       "modifiers": [
                                           "left_control"
                                       ]
                                   }
                               ],
                               "type": "basic"
                           }
                       ]
                   }
               ]
