Local prune: garden.Prune() removes orphaned blobs. 2 tests. CLI commands: sgard push, sgard pull (with SSH auth via --ssh-key or ssh-agent), sgard prune (local by default, remote with --remote). Server daemon: cmd/sgardd with --listen, --repo, --authorized-keys flags. Runs gRPC server with optional SSH key auth interceptor. Root command gains --remote and --ssh-key persistent flags with resolveRemote() (flag > env > repo/remote file). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
sgard — Shimmering Clarity Gardener
A dotfiles manager that checkpoints files into a portable repository and restores them on demand.
The repository is a single directory that can live anywhere — local disk, USB drive, NFS mount — making it portable between machines.
Installation
Homebrew:
brew tap kisom/homebrew-tap
brew install sgard
From source:
git clone https://github.com/kisom/sgard && cd sgard
go build -o sgard ./cmd/sgard
Or install into $GOBIN:
go install github.com/kisom/sgard/cmd/sgard@latest
NixOS (flake):
nix profile install github:kisom/sgard
Or add to your flake inputs and include sgard.packages.${system}.default
in your packages.
Binaries are also available on the releases page.
Quick start
# Initialize a repo (default: ~/.sgard)
sgard init
# Track some dotfiles
sgard add ~/.bashrc ~/.gitconfig ~/.ssh/config
# Checkpoint current state
sgard checkpoint -m "initial"
# Check what's changed
sgard status
# Restore from the repo
sgard restore
Use --repo to put the repository somewhere else, like a USB drive:
sgard init --repo /mnt/usb/dotfiles
sgard add ~/.bashrc --repo /mnt/usb/dotfiles
sgard restore --repo /mnt/usb/dotfiles

How it works
sgard stores files in a content-addressable blob store keyed by SHA-256. A YAML manifest tracks each file's original path, hash, type, permissions, and timestamp.
~/.sgard/
manifest.yaml # human-readable manifest
blobs/
a1/b2/a1b2c3d4... # file contents stored by hash
On restore, sgard compares the manifest timestamp against the file's
mtime. If the manifest is newer, the file is restored without prompting.
Otherwise, sgard asks for confirmation (--force skips the prompt).
Paths under $HOME are stored as ~/... in the manifest, making it
portable across machines with different usernames.
