## Introduction

This repository handles installation of dependencies on Apple Silicon M1. The pre-requisites for this repo to be running is nothing. Ideally, this is to scratch setup i.e. if you have freshly purchased a Macbook M1.

## Dependencies

* Zsh (default shell in Mac os)
* Installation of `oh-my-zsh` is recommended since it has default tools and plugins. Refer `prereq.sh` file for installations.
* Git (Xcode Command line tools. If not present run `xcode-select --install`)

## How to run

To execute the scripts, first you need to open the terminal of your choice preferrably `iTerm2`.
* If you have `oh-my-zsh` installed, you can skip the `prereq.sh`. If not, enter `zsh prereq.sh` which will install the shell.
* Once this done, you can move ahead in installing dependencies, by running `zsh deps_part1.sh`. This will install all the dependencies listed below.

## Part 1

Part 1 deals with installing basic dependencies necessary for developer to get started. Following are the tools that are supported as of now. Native support for `brew` has arrived for many formulae and they have been changed accordingly. The Rosetta version of `brew` has been kept for comptability purposes but might be removed in later commits.

- [x] Homebrew (Rosetta working, Native also working...)
- [x] Golang
- [x] ADB
- [x] OpenJDK
- [x] Htop
- [x] Node.JS (As of now, only v15 is supported)
- [x] NVM (Node Version Manager)
- [x] Heroku CLI
- [x] Redis
- [x] PostgreSQL
- [x] Yarn
- [x] Python
- [x] sqlc - SQL Compiler

Note that `Node.JS` would take a bit of time to install, as it needs to be built from source. This might involve usage of all cores and laptop getting a bit hot. `Python 3.9` is installed under Native M1 and `pyenv` has been setup under native `brew` which resides in `/opt/homebrew`

## Part 2

- [x] [Docker Developer Release](https://docs.docker.com/docker-for-mac/apple-m1/)

## Theme

![Terminal Theme](https://raw.githubusercontent.com/hjoshi123/M1DevSetup/master/theme/terminal.png)

The theme used for zsh is `agnoster`. The default theme has been edited to change some elements to make it visually more appealing and add more information.

* Once you install zsh, head over to `.zshrc` and edit the following `ZSH_THEME=` to `ZSH_THEME="agnoster"`.
* Install Powerline fonts (if required). Head over to [Powerline](https://github.com/powerline/fonts) for more details. I have choosen `Meslo LG S for Powerline` as my default font.
* Now cd to `.oh-my-zsh/themes` and replace the contents of `agnoster.zsh-theme` with the one given in the repo.
* Run `source ~/.zshrc` inside the terminal.

## Disclaimer

Note that `homebrew` under Rosetta is installed in `/usr/local/bin`. The official M1 supported version would be installed in `/opt/homebrew`. Whichever brew is in your path first will run when you use brew. If it’s the `/usr/local` one, you’ll need to add the `arch -x86_64` prefix every time. Your best bet for using both is to alias one of them.

UPDATE: As described above, the script has been updated to install both M1 and Rosetta (Intel) based homebrews with rosetta based having alias `ibrew`. Do note that the installations still remain under Intel as some of the formulae aren't supported natively yet.

To avoid this situation, what could be done is that Rosetta Homebrew could be given an alias like `ibrew` so that your brew points to the actual `ARM M1` version when the full support comes. This is a WIP and I will update the scripts so that we can have a native brew and an `ibrew` for Rosetta 2.

Some things might be broken in the script, I am working to fix the problems. Your comments and suggestions in the form of issues are always appreciated.
