The vimrc file is a slightly modified version of the one from here: https://github.com/zenbro/dotfiles

Installation of neovim + some other useful tools

Note: this instruction is intended for Ubuntu 14.04 gnome, for newer Ubuntu versions some steps may look different

If you are on a fresh system, you may want to do these first steps:

Set up window switch on alt-tab, terminal launch opens new terminal window *TODO*
Switch off linux hotkeys for F1-F10 and Ctrl+Left, Ctrl+Right, because we will need to customize them *TODO*
Update and upgrade if necessary and install curl, git and build-essential

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install curl git build-essential

Install python dev packages, we are going to need it for code completion plugin later...

sudo apt-get install ctags python-pip python3-pip
sudo apt-get install python2.7-dev python3.4

Install ctags, meld

sudo apt-get install ctags meld

Install clang, (see https://stackoverflow.com/questions/30549502/installed-clang3-6-on-ubuntu-cant-select-as-alternative/30742451#30742451) for ubuntu 16 and newer clang version see https://blog.kowalczyk.info/article/k/how-to-install-latest-clang-5.0-on-ubuntu-16.04-xenial-wsl.html

sudo apt-get install git  llvm clang-3.5 lldb3-5

sudo update-alternatives --install /usr/bin/cc cc /usr/bin/clang-3.5 100
sudo update-alternatives --install /usr/bin/c++ c++ /usr/bin/clang++-3.5 100

If at any time you need to switch back to gcc or g++ you can use the --config option:

sudo update-alternatives --config c++

Create symbolic links for clang

sudo ln -s /usr/bin/clang-3.5 /usr/bin/clang
sudo ln -s /usr/bin/clang++-3.5 /usr/bin/clang++

sudo pip2 install --upgrade neovim
sudo pip3 install --upgrade neovim

Install vim plug *TODO: the init.vim config file should auto load vim plug on first start - check if this really works*

curl -fLo ~/.config/nvim/autoload/plug.vim --create-dirs \
     https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

Clone the dot files (this repository) and copy them to the appropriate locations

git clone https://github.com/conceptacid/dotfiles.git
cd dotfiles/
cp init.vim ~/.config/nvim/
rm -rf dotfiles

...the last but not least, download the default script for YouCompleteMe into your home directory

curl -fLo ~/.ycm_extra_conf.py https://raw.githubusercontent.com/Valloric/ycmd/master/cpp/ycm/.ycm_extra_conf.py

Start neovim nvim and hit enter to ignore any errors, the vim plug will install all the missing plugins...

nvim .

Restart neovim and run :PlugInstall command once again to make sure there are no errors this time. Now you're done with neovim.

Install Golang
