ARCHITECTURE.md: update package structure to reflect actual file layout (per-operation files, version command, flake, goreleaser), fix Garden struct (clock field, Restore confirm callback, List method), add .gitignore to repo layout, remove stale C++ note. README.md: add NixOS installation instructions. CLAUDE.md: add nix build command. PROGRESS.md: add post-Step-8 release work to change log.

# 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](https://github.com/kisom/sgard/releases).
|
|
|
|
## Quick start
|
|
|
|
```sh
|
|
# 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:
|
|
|
|
```sh
|
|
sgard init --repo /mnt/usb/dotfiles
|
|
sgard add ~/.bashrc --repo /mnt/usb/dotfiles
|
|
sgard restore --repo /mnt/usb/dotfiles
|
|
```
|
|
|
|
## Commands
|
|
|
|
| Command | Description |
|
|
|---|---|
|
|
| `init` | Create a new repository |
|
|
| `add <path>...` | Track files, directories, or symlinks |
|
|
| `remove <path>...` | Stop tracking files |
|
|
| `checkpoint [-m msg]` | Re-hash tracked files and update the manifest |
|
|
| `restore [path...] [-f]` | Restore files to their original locations |
|
|
| `status` | Show which tracked files have changed |
|
|
| `diff <path>` | Show content diff between stored and current file |
|
|
| `list` | List all tracked files |
|
|
| `verify` | Check blob store integrity against manifest hashes |
|
|
| `version` | Print the version |
|
|
|
|
## 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.
