Background:

Vim is an amazing editor and I have been using it for almost 5 years now. I am so used to vim that when I open a file in any other editor I type something and hit :w to save. ( Vim users know what I am talking about ). Over the years every one have their own settings, vim scripts (Plugins), themes etc. And every now and then you find some interesting setting which you want to add to your config (vimrc) or some new plugin for css3. Taking all your settings along with you is a pain if you didn’t sync them some where. I work in different hosts for different projects and keeping Vim in sync across is not easy. This is where Vundle and your favorite version control come into picture.  The solution is simple and straight forward.You sync it somewhere using version control and get it to your working environment where you want to sync.

I use Git to sync it online. You are free to use any version control. Now what does Vundle do? Well Git keeps your  Vimrc and other stuff like themes etc in sync and Vundle manages your plugins. Vundle is a package manager for vim, and these days almost all plugins are hosted at Git. So Vundle makes them easy to install,update or remove. All you need to do is add Bundle 'mattn/emmet-vim' to install emmet plugin into your vim.

Sync Vim online

To sync vim online you have 2 steps. One is setting up your repo in github and getting your vim ready. Two is syncing when needed.
Setting up your Vim:

mv .vimrc ~/.vim/.vimrc
ln -s ~/.vim/.vimrc ~/.vimrc

Now Set up your Git:

cd ~/.vim
git init
touch README.md
git add --all
git commit -m "First commit for syncing dot vim"

Now create a guthub repo as you have a local repo ready. You can do that using this link. Read the Make a new repository on GitHub section and after creating a repo get the repo url usually

https://github.com/username/repository-name.git

Now with this url add it to git remote

git remote add origin git@github.com:username/repository-name.git 
git push origin master

Now your vimrc and other settings in your vim is stored in github. Now you need to manage plugins so install vundle.
Installing Vundle:
see link for more installation help.

git clone https://github.com/gmarik/vundle.git ~/.vim/bundle/vundle

And add these lines to .vimrc

set nocompatible               " be iMproved
filetype off                   " required!
 
 set rtp+=~/.vim/bundle/vundle/
 call vundle#rc()

 " let Vundle manage Vundle
 " required! 
 Bundle 'gmarik/vundle'
 filetype plugin indent on     " required!

To install bundles you add something like this to your vimrc

Bundle 'tpope/vim-fugitive'
Bundle 'Lokaltog/vim-easymotion'

Now launch vim and run :BundleInstall


Now you don’t want git to track your bundles as Vundle does the job for you. so create a .gitignore file and add these lines to the file to tell git to ignore these files.

~/.vim/bundle/*
bundle/*

Now part 2. Setting sync in your other environment. Go to your environment where you want to sync vim and do the following

1) Cloning your dotvim. The repo that you created while setting up your git.
	git clone https://github.com/username/repository-name.git 
2) soft link your vimrc
	ln -s ~/.vim/.vimrc ~/.vimrc
3) Seting up Vundle
	git clone https://github.com/gmarik/vundle.git ~/.vim/bundle/vundle
4) Installing the packages
	open vim and execute :BundleInstall

And voila… Your Vim is in sync!
