This is mostly a note to myself on how to set up a fresh MacOS for Java Development. You can use these instructions to install Neovim and my dotfiles configuration, just follow them from the beginning up to Java section. If you are only interested in Neovim, you need only brew from the Bare Essentials (see below).

Open source software changes rapidly and usually with no concern for backwards compatibility. I learned this the hard way when installing my dotfiles in a new Mac. Newest tmux and neovim versions introduced changes that broke my configurations resulting in annoying bugs. Fixing these bugs sometimes takes a persistent and time consuming research on relevant online resources. Just keep this in mind while installing my dotfile configuration in your system. I did the best I could to document my installation during an actual new setup.

• Download and install Chrome
• Install Magnet for Window Management
• Install Brew
• Assign Basic Fn keys (Settings/keyboard/shortcuts) F2 Focus on menu bar, F3 Focus dock, F4 next active window

brew cask install iterm2

ssh-keygen -t rsa -C "kabasakalis@gmail.com" Copy the contents of the public key /Users/{user}/.ssh in my github and bitbucket key configurations.

brew install coreutils
brew install zsh zsh-completions
Run zsh for default configuration. Copy the following line to .zshrc:
fpath=(/usr/local/share/zsh-completions $fpath)

curl -L /~https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh | sh Switch shell from bash to zsh, in command line: chsh -s /bin/zsh The defaul .oh-my-zsh.zsh will be later overwritten from my dotfiles.

Download and install Powerline fonts.
cd fonts && install.sh

Make sure neovim/plugins.vim file in dotfiles contains Plug 'ryanoasis/vim-devicons'
Install Nerd fonts simply with
brew tap caskroom/fonts
brew cask instald font-hack-nerd-font
Also checkout instructions in nerd-fonts

After you have installed powerline fonts and nerd fonts you have to use them in iTerm2. Go to iTerm2 preferences and assign your favorite powerline font as the main editor font, and your favorite nerd font as the non-character font (used to render file-icons among other eye candy).

Add in .bashrc to make zsh default shell

if [ -t 1 ]; then
 exec zsh
fi

brew install neovim

sudo gem install rubocop rubocop-rspec starscope ruby-beautify haml-lint scss-lint mdl neovim && npm install js-beautify && install exuberant-ctags && install xclip rcodetools

sudo gem install tmuxinator

Install Python. This is required from Neovim.
brew install python (version 3)
brew install python@2 (version 2)
Then install these libraries:

pip3 install \
virtualenv \
flake8 \
isort \
jedi \
mistune \
psutil \
psutil \
setproctitle \
neovim \

pip2 install \
virtualenv \
flake8 \
isort \
jedi \
mistune \
psutil \
psutil \
setproctitle \
neovim \

Add in dotfiles/neovim/init.vim:
let g:python_host_prog = "/usr/local/bin/python2"
let g:python3_host_prog = "/usr/local/bin/python3"

Mainly for awesome tmuxinator gem
Make appropriate changes in .zshenv (default ruby version if you want to install a version manager).

brew cask install xquartz
brew install xclip

Install node.js, download pkg file.
Run in terminal npm install -g neovim

brew install the_silver_searcher

One of two ways:

1. brew install tmux

2. Run script, (edit version first) ./dotfiles/scripts/tmux_install.sh

(bottom bar in screenshot).See my disclaimer on top of this page. I was not able to make this work with the newer version of tmux.

git clone git@github.com:kabasakalis/dotfiles.git in your home folder.
cd dotfiles
git submodule update --init --recursive (fetches dotbot)
./dotbot/bin/dotbot -d ~/dotfiles -c ~/dotfiles/installmac.conf.yaml

Start iTerm2 and then neovim with nvim executable and type command
:PlugInstall (Plugins may install automatically on neovim startup)

Create yml configuration files inside dotfiles/tmuxinator folder, with name name, and start the session with alias txs name. Stop session with tks name.

In neovim run :checkheath and make sure there are no errors or warnings.

brew update
brew tap caskroom/cask

To check JDK 10 (latest)
brew cask info java

brew tap caskroom/versions
brew cask install java6
brew cask install java7
brew cask install java8

brew cask install java

brew install jenv

In .zshrc set:
eval "$(jenv init -)"
Add java paths in jenv, run in command line:
jenv add /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home/
jenv add /Library/Java/JavaVirtualMachines/jdk1.8.0_66.jdk/Contents/Home/
Check java versions:
