Quick Start

git clone --recurse-submodules https://github.com/BumpyClock/dotfiles.git
cd dotfiles

Unix/Linux/macOS

./shell/zsh/install-deps.sh
bun scripts/link-dotfiles/link-dotfiles.ts --dotfiles-dir "$PWD" --setup both

On Unix/macOS, the linker manages ~/.zshrc. It backs up an existing unmanaged file once, writes a small managed entrypoint that sources shell/zsh/shared.zsh, and creates ~/.zshrc.local for machine-specific customizations.

Windows (PowerShell)

bun scripts/link-dotfiles/link-dotfiles.ts --dotfiles-dir "$PWD" --setup both

On Windows, directory links are created as junctions (no elevation needed).
If file symlinks are blocked, the linker falls back to hardlinks; only if both are blocked should you run elevated or enable Developer Mode.

Linker CLI

Primary entrypoint is scripts/link-dotfiles/link-dotfiles.ts.

# Interactive chooser: dotfiles, ai-agents, or both
bun scripts/link-dotfiles/link-dotfiles.ts --dotfiles-dir "$PWD"

# Non-interactive
bun scripts/link-dotfiles/link-dotfiles.ts --dotfiles-dir "$PWD" --setup dotfiles
bun scripts/link-dotfiles/link-dotfiles.ts --dotfiles-dir "$PWD" --setup ai-agents
bun scripts/link-dotfiles/link-dotfiles.ts --dotfiles-dir "$PWD" --setup both

# Status
bun scripts/link-dotfiles/link-dotfiles.ts --dotfiles-dir "$PWD" --show

# Link repo agents into a project's .claude/agents
bun scripts/link-dotfiles/link-dotfiles.ts --dotfiles-dir "$PWD" --setup dotfiles --project-agents /path/to/project

AI-agent destination mappings are defined in scripts/ai-agent-links.json.

During setup, installable CLI sources in tools/ are also published into ~/.local/bin. TypeScript/Bun tools are compiled into native binaries on the current OS, while other shebang-based tool scripts are linked directly. If secrets/api-keys/env.json exists, the linker also generates ~/.config/dotfiles/env.sh and ~/.config/dotfiles/env.ps1 so shells can load managed API keys automatically.

On Unix/macOS, the linker also manages ~/.zshrc. Existing unmanaged content is moved to a timestamped backup such as ~/.zshrc.backup.20260518_143000; personal shell snippets belong in ~/.zshrc.local, which the managed entrypoint sources after the shared config.

Submodules

git submodule update --init --recursive

References and Attribution

Notes

  • ~/.zshrc is managed by the linker on Unix/macOS. Use ~/.zshrc.local for machine-specific shell snippets; existing unmanaged ~/.zshrc content is preserved in a timestamped backup on first migration.
  • scripts/sync-github-folder.{sh,ps1} remain available for project-level .github syncing.
  • tools/trash.ts moves files and directories to the system trash on macOS, Windows, and Linux; Linux support is best-effort through the underlying XDG-compatible backend.
