Install my SSH and GPG keys

Fix macOS Sierra ssh-agent issue

cat >> ~/.ssh/config <<EOF

Clone the dotfiles

mkdir -p ~/Projects
git clone git@github.com:tungd/dotfiles-lean.git ~/Projects/dotfiles

Making aliases

mkdir -p ~/.local/bin

ln -s ~/Projects/dotfiles/.bash_profile ~/.bash_profile
ln -s ~/Projects/dotfiles/.bashrc ~/.bashrc
ln -s ~/Projects/dotfiles/.emacs.d ~/.emacs.d
ln -s ~/Projects/dotfiles/.gitconfig ~/.gitconfig
ln -s ~/Projects/dotfiles/.npmrc ~/.npmrc
ln -s ~/Projects/dotfiles/.eslintrc ~/.eslintrc

Install apps and utilities

XCode

xcode-select --install

nix

The global CLI profile is managed from this repo:

nix profile install ~/Projects/dotfiles/nix/profile
nix profile upgrade --impure nix-profile

It currently owns small standalone tools that should not be installed via MacPorts:

cloudflared direnv emacs-weekly fd fzf gh git-lfs htop jq opam ripgrep tmux tokei tree universal-ctags uv valkey wget

macports

No longer used; global tools moved to the Nix profile above.

I also maintained a separate port for building Emacs. I have it updated weekly.

The replacement is nix/profile/packages/emacs-weekly.nix.
