MyMac Setup

Rebuild script

Show hidden files

Launch any terminal and run:

$ defaults write com.apple.finder AppleShowAllFiles YES; killall Finder

Development environment

If a Bourne-shell (bash) is installed with make utils, execute:

$ make build

And copy configuration files across:

$ make install

Manual installation

Install Homebrew

Launch terminal and execute:

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

with the latest Homebrew version (2.2.2),

• Apple's Xcode will be downloaded automatically,
• once the bootstrap script has installed the brew executable,
• while the core and cask taps are installed by default.

In $PATH, make sure /usr/local/bin is before /usr/bin:

export PATH=/usr/local/bin:/usr/local/sbin:$PATH

Install Zsh

With Homebrew setup as the default package manager:

$ brew install zsh

with MacOS Catalina,

• Apple base shell has been switched to the Z-shell.

Allow system to access the shell and make Z-shell the defaut shell:

$ sudo echo $(which zsh) > /etc/shells
$ chsh -s $(which zsh)

In order to switch back to the Bourne-shell:

$ chsh -s $(which bash)

Install Oh-My-Zsh

Launch terminal and execute:

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

Install Pyenv

To get Pyenv installed:

$ brew install pyenv pyenv-virtualenvwrapper

And make sure to add the following into your ~/.zshrc:

# Pyenv
eval "$(pyenv init -)"
# Pyenv-virtualenvwrapper
export WORKON_HOME=${HOME}/.pyenv
eval "pyenv virtualenvwrapper"

Install Rbenv

To get Rbenv installed:

$ brew install rbenv

And make sure to add the following into your ~/.zshrc:

# Rbenv
eval "$(rbenv init -)"

Lastly... cheatsheet!

Generate SSH keys

Either generate key pair id_rsa / id_rsa.pub via ssh agent:

$ ssh-keygen -t rsa -b 4096 -C "label"
$ eval "$(ssh-agent -s)"
$ ssh-add -K ~/.ssh/id_rsa

Or copy-over existing keys:

$ chmod 400 id_rsa
$ chmod 400 id_rsa.pub

Autoreload iPython shell

Install iPython in a Python virtual environment and generate a profile,

$ ipython profile create

Then amend the configuration file (found at ~/.ipython/profile_default/)

Django Shell_plus for PyCharm

Enable Django support in Languages & Frameworks > Django,

Then add the the following starting script in Build, Execution, Deployment > Django Console,

import sys

print(f"Python {sys.version} on {sys.platform}")
sys.path.extend([WORKING_DIR_AND_PYTHON_PATHS])

import django

print(f"Django {django.get_version()}")
if 'setup' in dir(django):
    django.setup()

import django_manage_shell

django_manage_shell.run(PROJECT_ROOT)

from django_extensions.management.shells import import_objects
from django.core.management.color import no_style

globals().update(
    import_objects({"dont_load": [], "quiet_load": False}, no_style())
)
