Rotz Dotfiles Management

Context for working with rotz, a Rust-based dotfiles management tool, and rotz-based dotfiles projects.

Rotz System Critical Context

Project location: ~/.charmschool (not default ~/.dotfiles)

Fish shell focused: config.yaml sets shell_command to fish -c, so install commands use Fish syntax

Rotz structure:

• Any directory with dot.yaml = installable "dot"
• dot.yaml keys: installs (commands), links (symlinks), depends (dependencies)
• defaults.yaml provides inherited defaults (dots inherit by setting keys to null)
• Handlebars templating: {{file_name name}}, etc.

Repository structure:

• agents/ - coding agent/CLI configs
• apps/ - Homebrew casks (GUI apps)
• tools/ - Homebrew formulae (CLI/TUI)
• shell/ - Fish, kitty, starship
• editor/ - Neovim (LazyVim)
• lang/ - language tooling (transitioning to mise)
• git/ - git tooling/config

dot.yaml Patterns

# Simple (inherit from defaults.yaml)
installs: null  # Gets "brew install <name>" from defaults
links:
  config: ~/.config/tool/config

# Custom install
installs:
  - brew install custom-tool
  - custom-tool --setup
links:
  config.toml: ~/.config/custom/config.toml
depends:
  - ../other-tool

Adding New Tools

1. Determine location: apps/, tools/, lang/, etc. (or propose new grouping)
2. Create dot.yaml:
   • Use installs: null to inherit from defaults.yaml when possible
   • Explicit install commands for special handling
   • Declare dependencies (depends)
   • Set up config symlinks (links)
3. Study similar tools for consistency
4. Consider integration (e.g., fzf + fish functions)

Configuration Guidelines

Standards:

• Modern tools preferred (Rust/Go-based when advantageous)
• Optimize for fast shell startup (lazy-load heavy tools)
• XDG compliant (use ~/.config/ over ~/.*)
• Project-aware configs (mise auto-loading versions)
• Never expose credentials (use env vars)
• Comment non-obvious choices (beginner-friendly)
• Note macOS-specific configs

Code quality:

• Fish idioms in install commands (avoid bashisms)
• Idempotent install commands
• Error handling in scripts
• Clear dependencies, avoid tight coupling

Evaluation criteria for new tools:

• Necessity, maintenance/adoption, integration, simplification potential, performance impact, complexity cost

Restructuring

• Analyze current state thoroughly first
• Maintain logical grouping (clean hierarchy preferred)
• Update all dot references when moving directories
• Update/preserve defaults.yaml to reflect patterns
• Explain rationale for changes

Essential Commands

Prefer dot wrapper (safer, more features):

• Link: dot -l [path...] or rotz link [path...]
• Install: dot -i [path...] or rotz install [path...]
• Both: dot [path...]
• Force link: rotz link --force (use cautiously)
• Bootstrap: sh bootstrap.sh (fresh machines only)

Path notes:

• Paths are relative, no trailing slash (e.g., editor/nvim)
• dot strips trailing slashes if provided
• No path = all (use dot -a / --all, or very cautiously with rotz)
• dot supports -d/--dry-run

Fish vs bash/zsh (Footguns)

In rotz install commands (Fish syntax):

Bash/zsh	Fish
[[ ... ]]	test ...
command -v cmd	type -q cmd
VAR=value	set VAR value
export VAR=value	set -gx VAR value

Avoid set -U (universal scope): Fish moving away from this. Prefer global (set -gx) or local scope.

Style Conventions

• YAML/Lua: 2 spaces
• Shell choice:
  • General scripts: POSIX sh
  • User-facing/interactive: Fish
  • Coding agent CLIs: Bash
  • Agent tool scripts: Deno
• Fish functions:
  • Location: shell/fish/functions/
  • Filename = function name (foo.fish defines foo)
  • Include -d "description" and --help
• Comments: Explain rationale, beginner-accessible
• Theming: Catppuccin Frappe when possible

Tool-Specific Notes

mise: Check docs (rapidly evolving). Use for tasks, environments, versions. Optimize for fast startup.

uv: Primary Python package manager. Set up pyproject.toml, integrate with mise.

fish: Idiomatic functions/abbrs. Prefer global scope over universal. Optimize config.fish startup.

fzf: Advanced options, keybindings. Integrate with ripgrep, fd. Fish-specific functions, preview optimization.

ripgrep: Configure .ripgreprc defaults, custom type definitions. Integrate with fzf.
