😼 Homebrew

Before any installation, you should approve XCode license agreement by the following command:

$ sudo xcodebuild -license

You should execute the following command to install Homebrew:

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

If you are asked about XCode Command line tool while installing with Homebrew, please install it.

🗻 Oh-my-zsh

If you want to use a coftable Zsh customized by the community, let’s install
robbyrussell/oh-my-zsh.

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

👽 git

You should install git command line tool:

$ brew install git
$ git config --global user.name "USER_NAME"
$ git config --global user.email email@example.com
$ git config --global tag.sort version:refname

After installing git, we recommend to set global .gitignore:

# generator about .gitignore
$ brew install gibo

# Set some unnecessary files of JetBrains and Mac to .gitignore
$ gibo JetBrains OSX > .gitignore

# Set the .gitignore to set git global setting
$ git config --global --add core.excludesfile "$HOME/.gitignore"

You should set basic passwords to skip filling password by vi ~/.netrc:

machine github.com
login USERNAME
password PASSWORD

In addition, please add a alias git push-f to vi ~/.gitconfig

[alias]
  push-f = push --force-with-lease

🍣 autojump

If you want to fill a path more quickly,
wting/autojump is one of the greatest solutions.

$ brew install autojump

After installing, set the following setting by vi ~/.zshrc

# autojump
[[ -s $(brew --prefix)/etc/profile.d/autojump.sh ]] && . $(brew --prefix)/etc/profile.d/autojump.sh

After the setting, execute the following command to reflect the setting:

$ source ~/.zshrc

🏀 Font Ricty

Ricty is a fonts for programming, if you want to try it, please set the following command:

# Installing Ricty
$ brew install automake
$ brew tap sanemat/font
$ brew install Caskroom/cask/xquartz
$ brew install ricty

# Copy generated font information
$ cp -f /usr/local/Cellar/ricty/3.2.2/share/fonts/Ricty*.ttf ~/Library/Fonts/
$ fc-cache -vf

# Setting about anti-alias
$ defaults -currentHost write -globalDomain AppleFontSmoothing -int 2

😸 rbenv

To avoid installing unnecessary documents, add the following setting vim ~/.gemrc:

install: --no-document
update: --no-document

After the above setting, let’s install the following rbenv and ruby-build:

# Installing rbenv / ruby-build
$ brew install rbenv ruby-build

# Setting to installing gems when introducing new version
$ git clone https://github.com/sstephenson/rbenv-default-gems.git ~/.rbenv/plugins/rbenv-default-gems

# Setting default install gems
$ echo 'bundler\nrails\npg\ndokku-cli' > ~/.rbenv/default-gems

Edit the following setting by vi ~/.zshrc:

# rbenv
[[ -d ~/.rbenv  ]] && \
  export PATH=${HOME}/.rbenv/bin:${PATH} && \
  eval "$(rbenv init -)"

The setting is reflected by the following command:

$ source ~/.zshrc

Install Ruby by rbenv:

# show list of ruby versions which is able to install
$ rbenv install -l

# Install latest ruby version(e.g. 2.3.1)
$ rbenv install 2.3.1
$ rbenv global 2.3.1

🐡 PostgreSQL

# Install PostgreSQL
$ brew install postgresql

# To have launchd start postgresql at login:
ln -sfv /usr/local/opt/postgresql/*plist ~/Library/LaunchAgents

# Then to load postgresql now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

🐹 Docker

I think that we will use Docker in the near feature.
If you agree with my opinion, please install some docker images:

$ docker pull ruby:2.3.1
$ docker pull postgres:latest
$ docker pull redis:latest
$ docker pull ubuntu:14.04

After downloading the docker image, please set alias to vi .zshrc:

# Docker
alias d='docker'
alias dc='docker-compose'
alias dm='docker-machine'

After setting, reflect the upper settings:

source ~/.zshrc
