Setup your Macbook as a developer machine

Create this article to summarize my scirpts to setup my Macbook:

Install ruby and rvm

curl -sSL https://get.rvm.io | bash -s stable --ruby
# install bundler
gem install bundler
# Add the following line into .bash_profile or .zshrc
source ~/.rvm/scripts/rvm

Setup VIM

brew rm vim vim python
brew install python
brew install vim --with-override-system-vi

Note: if python3 is not installed or configured as default

brew install macvim --with-cscope --with-lua --with-override-system-vim --with-luajit --with-python
brew linkapps macvim

Troubleshooting

Sometimes you get weird errors in VIM, due to the integration of various libraries.

One error you might frequently see in MacVim is about python:

E887: Sorry, this command is disabled, the Python's site module could not be loaded.

Follow this link regarding how to install vim properly in Mac.

Note: Sometimes you will have to reinstall everything to resolve this.

Intellij-IDEA

brew cask install intellij-idea-ce

iTerm configuration

Setup zsh/oh-my-zsh

# install zsh first
brew install zsh zsh-completions
# install oh-my-zsh on top of zsh
curl -L https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh | sh
#make zsh the default shell if not yet
chsh -s /usr/local/bin/zsh

Configure iTerm color thems

Download and configure iTerm color thems

configure zsh themes

# Add the following into .zshrc
ZSH_THEME=pygmalion

# enable plugins for git, vagrant, etc.
plugins=(git vi-mode colored-man colorize github vagrant brew mvn Forklift gradle httpie node npm pip python ruby rvm screen tmux osx zsh-syntax-highlighting)

Note: if you receive the following errors when using fl for Forklift, it’s very likely caused by the assistive access for Script Editor.

System Events got an error: osascript is not allowed assistive access. (-1719)

To enalbe the assitive access, go to System Preferences > Security & Privacy > Privacy > Accessibility.

Make sure Script Editor is checked in the list.

Configure SSH with remote server

• How To Configure SSH Key-Based Authentication on a Linux Server

enable vi mode in zsh

export VISUAL=vim
autoload edit-command-line; zle -N edit-command-line
bindkey -M vicmd v edit-command-line

ssh-config

store passphrase to keychain

Add you key file to keychain

/usr/bin/ssh-add -K /path/to/private_key

Note make sure use the capital K, and if it complains about the option not supported, make sure you use /usr/bin/ssh-add.

in your ~/.ssh/config file

 Host server.example.com
    IdentityFile ~/.ssh/id_rsa
    UseKeychain yes

If you are sharing your ssh configuration with systems running older versions of OpenSSH that don’t understand the UseKeychain option, you can specify the IgnoreUnknown option to keep your configuration compatible with both new and old versions, like this(just put it at the beginning of the config file):

IgnoreUnknown UseKeychain

See details in https://developer.apple.com/library/archive/technotes/tn2449/_index.html And also https://github.com/jirsbek/SSH-keys-in-macOS-Sierra-keychain

Troubleshooting

• I have recently experienced a random issue that iTerm hangs and I have to do a OS reboot to clear it up. It’s fairly painful, since Terminal.app is affected also. I ended up using Hyper Terminal as a backup when this occurs and I don’t want to reboot. I haven’t figured out the root cause of the issue yet. Here is a stackover flow discussion around the same issue. I will post an update once I have this fixed.
• Use time zsh -c -i exit to tune up the zsh loading time.

Tune startup time for zsh

If you notice slow startup time of zsh, you can use the following command to measure the startup time. And then you can adjust the zsh config to see how you can optimize it. A binary search is usually very helpful to identify what’s caused the slowness. Somehow, I found nvm is incredibly slow on MacOS. So I have to create a function to only enable it when I need it.

time zsh -i -c exit

• Another option is to use zprof to find out what has contributed to the longer loading time.
• If you can also use lazy load for some time-consuming plugins to reduce the startup time. Refer to this article: - https://kevin.burke.dev/kevin/profiling-zsh-startup-time/
