Adding git branch on the Bash/ZSH command prompt
------------------------------------------------

Add the following line to your .bashrc/.zshrc:
  source ~/utils/git-prompt.sh
(we assume git-prompt.sh is located in ~/utils/)

Change your PS1 to call __git_ps1 as command-substitution:
  Bash:
    PS1='\[\e]0;\w\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]$(__git_ps1 " (%s)")\n\$ '
  ZSH:
    setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '


Adding git completion for the Bash
----------------------------------

Add the following line to your .bashrc:
  source ~/utils/git-completion.bash


Global git configuration
------------------------

Create symbolic link to local git.config to use it as global Git configuration:
  $ ln -s ~/utils/git.config ~/.gitconfig


Git scripts source
------------------

git-completion.bash and git-prompt.sh are taken from
https://github.com/raw/git/git/master/contrib/completion/

  $ wget https://github.com/raw/git/git/master/contrib/completion/git-completion.bash
  $ wget https://github.com/raw/git/git/master/contrib/completion/git-prompt.sh


Show diff output as two windows in vimdiff
------------------------------------------

To use you can create a symbolic link to xd in /usr/local/bin:
  $ ln -s ~/utils/xd /usr/local/bin/xd

Usage:
  $ git diff ... |xd
  $ hg diff ... |xd
  $ svn diff ... |xd
  $ cat some.patch |xd

You can also preprocess diff output to get more precise results:
  $ git diff ... |grep -v ... |sed ... |xd
  $ cat some.patch |grep -v ... |sed ... |xd


YouCompleteMe configuration for the linux kernel
------------------------------------------------

Replace "/home/pcie/ac/mld/" in the file ycm_extra_conf.py with your path to
the kernel sources.  Then

  $ ln -s ~/utils/ycm_extra_conf.py  <your-kernel-source-root>/.ycm_extra_conf.py
