This is a personal guide for how to setup Fish & Ruby in macOS Monterey running on an Apple/Silicon M1. asdf is used as a version manager for Node and Ruby.

Homebrew

Go to https://brew.sh/ and run the script.

On this version of macOS, it installs to /opt/homebrew. This means that paths that reference /usr/local/share should instead reference /opt/homebrew/opt/<package-name>/share. This can be a little confusing when following guides. I guess you could do some symlinking to avoid this.

Fish

Skip if you prefer bash or zsh :)

This guide is pretty good.

You may need to use this guide to set fish as your default shell.

Don't forget to add brew to fish path: set -U fish_user_paths /opt/homebrew/bin $fish_user_paths

As a reminder, the fish config file (equivalent of .bash_profile) is stored in ~/.config/fish/config.fish.

asdf

asdf is the version manager we will use for Node and Ruby. Use this guide, relevant stops copied over here.

Install asdf (fish specific)

brew install asdf
echo -e "\nsource "(brew --prefix asdf)"/libexec/asdf.fish" >> ~/.config/fish/config.fish

Now we can add the Node and Ruby plugins.

asdf plugin add nodejs https://github.com/asdf-vm/asdf-nodejs.git
asdf plugin add ruby https://github.com/asdf-vm/asdf-ruby.git

Go to the repo and run asdf install to install the relevant versions of Node and Ruby. You can check the current versions using asdf current.

Personal config

Install iTerm2. Go to Profile.

• Uner General->Working Directory, set to "Reuse previous session's directory"
• Under Colors, set background colour to 14191e and foreground colour to dbdbdb.
• Under Keys->Key mappings, set the preset to Natural Text Editing (allows for opt+arrow for word navigation).

Run fish_config. Set Dracula as your colour theme.
