New Mac Dev Setup

mac-dev-setup

Every few years when I have to upgrade my MacBook getting it setup for development is usually an endeavor. I created this to help me install dev essentials or as a helpful starting place for others.

In a previous life I was a full-stack web developer (primarily ruby) but now I do more datascience work (Python and R). This spec reflects that mixed background.

I took lots of inspiration from:

• nicolashery/mac-dev-setup
• Tania Rascia

Getting Started

Configure the laptop according to your preferences, make you sure you are up-to-date on security patches

Clone this repository

mkdir ~/src
cd src
git clone https://github.com/elijahc/mac-dev-setup

Homebrew

Install the Homebrew package manager. This will allow you to install almost any app from the command line.

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install homebrew applications

cd ~/src/mac-dev-setup  && ./brew.sh

Git

I use Git/Github (obviously) as my Version Control System (VCS)

brew.sh should have installed git for you, now it just needs to be configured

touch ~/.gitconfig

Update gitconfig

[user]
  name   = Firstname Lastname
  email  = you@example.com
[github]
  user   = username
[alias]
  a      = add
  cm     = commit -m
  s      = status

With the above aliases, I can run git s instead of git status, for example. The less I have to type, the happier I am.

SSH

I often have to shell into remote systems for heavier duty work.

mkdir ~/.ssh && touch ~/.ssh/config

update .ssh/config

Host *
  AddKeysToAgent yes
  UseKeychain yes
  ForwardAgent yes

Host myssh
  HostName example.com
  User user

Create and RSA key:

ssh-keygen -t rsa -b 4096 -C "email@example.com"

Copy it to any hosts added to ~/.ssh/config:

ssh-copy-id myssh

Vim

I keep heavily customized configs for Vim in separate dotfiles repo.

Otherwise, Tim Pope as a set of sensible vim defaults.

mkdir -p ~/.vim/pack/tpope/start
cd ~/.vim/pack/tpope/start
git clone https://tpope.io/vim/sensible.git

Shell

I like zsh. Catalina comes installed with zsh, but it can be installed with brew if necessary:

brew install zsh zsh-completions

Oh My Zsh has sensible defaults. Install it with:

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Install zsh-syntax-highlighting:

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting

I like Avid theme

Programming Languages

Python

macOS, like Linux, ships with Python already installed. I like using pyenv to manage multiple versions of Python (ex: 2.7 and 3) should we need to.

Install pyenv via Homebrew by running:

brew install pyenv pyenv-virtualenv

Add the following to .bash_profile:

# Load pyenv and virtual env
if command -v pyenv 1>/dev/null 2>&1; then eval "$(pyenv init -)"; fi
if which pyenv-virtualenv-init > /dev/null; then eval "$(pyenv virtualenv-init -)"; fi

Ruby

Install rbenv

brew install rbenv

Add the following to .bash_profile/.bashrc:

eval "$(rbenv init -)"

Node

Use Node Version Manager (nvm) to install Node.js. This allows you to easily switch between Node versions, which is essential.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.2/install.sh | bash

Install the latest version:

nvm install node

Add the following to your .bash_profile:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion
