Settings in My Shell Profile that Just Make Sense

Here are some useful settings in my Zsh profile and a few other dotfiles.

# Docker stuff

If you have an M-series (Intel) Mac, put this in your .zshrc right now to avoid bad times later on with docker stuff

export DOCKER_DEFAULT_PLATFORM=linux/amd64

# Aliases

I work for a consulting agency, and have many different projects on my machine for many different clients. So I made aliases to change directories to where I might want to go.

# aliases for fast switching
# To use these, have a code folder that includes 3 folders: clients, internal, and personal
# clients with multiple repos should go in their own folder inside clients/
alias clients="cd ~/code/clients/"
alias personal="cd ~/code/personal"
alias internal="cd ~/code/internal"

alias a-cool-client-app="cd ~/code/clients/my-cool-client-app"

alias my-client-with-10-apps="cd ~/code/clients/this-client"
alias another-client-app="cd ~/code/clients/this-client/another-client-app"

# SSH

Make sure my ssh keys are always available in my terminal session. You may need to add the keychain option to ssh-agent if you set up ssh-agent to use a password from your keychain.

# make sure ssh keys are added
eval `ssh-agent`
ssh-add

# Ruby & Rails stuff

Suppress warnings & deprecations; use at your own risk!

# suppress warnings & deprecations from Ruby
export RUBYOPT='-W0'

Working on a Ruby version that requires OpenSSL 1.1? You'll want this. Swap in OpenSSL 3.0 as needed... See my friend John's blog post explaining the OpenSSL error situation with Ruby, an explanation I have been wanting and not finding for years now of dealing with these errors and only finding obscure Q&A posts with out of date or incredibly wrong/risky info on what to do about the issue.

Make sure this line goes above your rbenv init lines, if using.

export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix [email protected])"

Stick these in & uncomment as needed... See the above re: OpenSSL!

# export LDFLAGS="-L/opt/homebrew/opt/[email protected]/lib"
# export CPPFLAGS="-I/opt/homebrew/opt/[email protected]/include"
# export LDFLAGS="-L/opt/homebrew/opt/libpq/lib:$LDFLAGS"
# export CPPFLAGS="-I/opt/homebrew/opt/libpq/include:$CPPFLAGS"

# ASDF configs

If you're using ASDF for tool version management, but working on legacy projects or projects where others are not, set legacy_version_file = yes in $HOME/.asdfrc to make sure if your project already has a .ruby-version or .nvmrc or .node-version, ASDF will use it automatically.

# Git Configs

Here are things I like in my $HOME/.gitconfig:

Note the editor part is opening up VS Code, and saving when the file is closed in VS Code. You'll need to make sure you have the VS Code command line tools installed first. I like those because then I can do code . in any given folder to see that folder in my editor.

autoSetupRemote is nice; it lets me skip git push --set-upstream origin myBranchName and just git push even if the branch isn't on the remote yet.

The main alias is great if you work in repos where some of them are using main as the primary branch, and some still have master as the primary branch, and it's out of your control to fix this right now and never think about it again. It lets you do git main and it takes you to whichever branch exists.

[pull]
	rebase = false
[pager]
	log = less
[core]
	pager = cat
	autocrlf = input
	editor = code --wait
	excludesfile = ~/.gitignore_global
[alias]
	main = "!bash -c 'git switch $(git rev-parse origin/main >/dev/null 2>&1 && echo main || echo master)'"
[push]
	autoSetupRemote = true
