1. Developer Tools

I have been consistently using a series of commands for some time to reproduce a development environment across various machines. For the most part, these commands were kept as gists. Recently, I managed to compile them all into a single shell script and a runcom (rc) file. I hope this proves helpful to others!

1.2. setup_env.sh

Warning

The script is tested on Apple M2 Pro (should also work on M1) and zsh shell.

If you haven't already installed Xcode Command Line Tools, you'll see a message that The Xcode Command Line Tools will be installed.

Check the output below to see if the Command Line Tools are installed:

    ==> Searching online for the Command Line Tools
    ==> /usr/bin/sudo /usr/bin/touch /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress

Change to bash shell as Homebrew install script uses batch. Type bash and hit enter. You would see error "Bash is required to interpret this script" otherwise.
Install Homebrew (Pre-requisite)
Clone this repo: git clone https://github.com/yaravind/dev-tools.git
cd dev-tools
Copy .zshrc (or .bashrc based on your shell) to home directory: cp .zshrc ~/
Make setup_env.sh executable: chmod +x setup_env.sh
Run: ./setup_env.sh

Warning (on macOS)

Your terminal does not have App Management permissions, so Homebrew will delete and reinstall the app. This may result in some configurations (like notification settings or location in the Dock/Launchpad) being lost. To fix this, go to System Settings > Privacy & Security > App Management and add or enable your terminal.

1.2.1 Developer Folder

mkdir ~/Developer: It has a fancy icon in finder!

1.3 setup_jenv.sh

setp_jenv.sh automates the process of adding Java Virtual Machine (JVM) installations to the jenv version manager on a macOS system. Here is an overview of what the script does:

Uses /usr/libexec/java_home --xml to get xml output of the installed JVMs.
Parses the installation directories using xmllint
Adds the JVMs to jenv using jenv add command.
Lists the JVMs managed jenv versions command.

To list the version, architecture, and folder location of all installed JVMs on your Mac:

$ /usr/libexec/java_home --verbose

Output:

Matching Java Virtual Machines (2):
    11.0.25 (arm64) "Microsoft" - "OpenJDK 11.0.25" /Library/Java/JavaVirtualMachines/microsoft-11.jdk/Contents/Home
    1.8.0_422 (arm64) "Amazon" - "Amazon Corretto 8" /Users/aravind/Library/Java/JavaVirtualMachines/corretto-1.8.0_422/Contents/Home
/Library/Java/JavaVirtualMachines/microsoft-11.jdk/Contents/Home

alias gslc='git shortlog -sn'

gsu() { git log --shortstat --author="$1" | grep -E "fil(e|es) changed" | awk '{files+=$1; inserted+=$4; deleted+=$6; delta+=$4-$6; ratio=deleted/inserted} END {printf "Commit stats:\n- Files changed (total)..  %s\n- Lines added (total)....  %s\n- Lines deleted (total)..  %s\n- Total lines (delta)....  %s\n- Add./Del. ratio (1:n)..  1 : %s\n", files, inserted, deleted, delta, ratio }' - ;}
