Download MacVim from the official website.

Note: there is an alias for alias mvim that points to the application bin file; this way it can run from the terminal with the mvim command.

git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

In Mvim run:

:PluginInstall

sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

Add the following line to ~/.zshrc:

source ~/.vim/zshrc

Change the theme to Agnoster (ZSH_THEME="agnoster") if not already selected.

Fonts for powerline:

git clone https://github.com/powerline/fonts.git ~/Desktop/fonts &&
sh ~/Desktop/fonts/install.sh &&
sudo rm -R ~/Desktop/fonts

Select the font from the terminal.

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git 

git clone https://github.com/zsh-users/zsh-autosuggestions $ZSH_CUSTOM/plugins/zsh-autosuggestions

add in .zshrc:

plugins=(zsh-autosuggestions)

By default, word jumps (option + → or ←) and word deletions (option + backspace) do not work. To enable these, go to "iTerm → Preferences → Profiles → Keys → Load Preset... → Natural Text Editing → Boom! Head explodes"

By adding the source in .zshrc it will source the file automatically, but we can clean the output by adding the command in the settings. Add to the field "Send text at start" in iTerm: Pref->Profile->General:

clear; zen;

dconf write /org/gnome/desktop/input-sources/xkb-options "['caps:escape']"
