# Dotfiles Architecture Documentation
|
||||
|
||||
## Philosophy: μέτρον γὰρ καὶ συμμετρία καὶ τὸ πρόσφορον
|
||||
|
||||
This dotfiles system is built upon the prime directive: **"Prioritize durable, thoughtful solutions over expedient ones"**. The Greek principle of μέτρον (measure), συμμετρία (proportion), and τὸ πρόσφορον (what is fitting) guides every architectural decision.
|
||||
|
||||
## Core Principles
|
||||
|
||||
### 1. Durability Over Convenience
|
||||
- **Long-term thinking**: Solutions that remain stable across system updates
|
||||
- **Graceful degradation**: System continues to function when components are missing
|
||||
- **Version stability**: Lockfiles and rollback mechanisms prevent breaking changes
|
||||
|
||||
### 2. Thoughtful Modularization
|
||||
- **Single responsibility**: Each script and configuration file has a clear purpose
|
||||
- **Composable design**: Components work independently and together
|
||||
- **Context awareness**: System adapts behavior based on working directory and usage patterns
|
||||
|
||||
### 3. Measured Implementation
|
||||
- **What is fitting**: Tools and configurations chosen for specific needs, not trends
|
||||
- **Proportional complexity**: Simple solutions for simple problems
|
||||
- **Observable behavior**: System provides visibility into its operations
|
||||
|
||||
## System Architecture

|
||||
|
||||
## Component Design Rationale
|
||||
|
||||
### The "engage" Script
|
||||
**Inspiration**: Captain Picard's decisive command
|
||||
**Purpose**: Single-entry point for complete system deployment
|
||||
**Design**: Interactive menu with phased installation and pre-flight checks
|
||||
|
||||
```bash
|
||||
# Philosophy: Make complex deployment feel effortless
|
||||
echo "🖖 ENGAGE - Make it so!"
|
||||
```
|
||||
|
||||
### Shell Configuration Strategy
|
||||
**Problem**: Monolithic .zshrc files become unmaintainable
|
||||
**Solution**: Modular architecture with graceful degradation
|
||||
|
||||
**Key decisions**:
|
||||
- **environment.zsh**: Sets the foundation (XDG, locale, history)
|
||||
- **paths.zsh**: Intelligent PATH building with deduplication
|
||||
- **functions.zsh**: Enhanced system utilities (sysupdate, deep_clean, vault integration)
|
||||
- **Context awareness**: Behavior adapts to work/chamber/vault/dotfiles environments
|
||||
|
||||
### Package Management Philosophy
|
||||
**Brewfile Design**: Organized by purpose, not alphabetically
|
||||
```ruby
|
||||
# Development tools come first (core workflow)
|
||||
brew "git"
|
||||
brew "ripgrep"
|
||||
brew "fzf"
|
||||
|
||||
# Productivity tools second (daily usage)
|
||||
brew "obsidian"
|
||||
brew "raycast"
|
||||
```
|
||||
|
||||
**Rationale**: Reflects actual importance hierarchy, not convenience
|
||||
|
||||
### Version Control Strategy
|
||||
**Three-tier approach**:
|
||||
1. **Brewfile**: What should be installed
|
||||
2. **Brewfile.lock**: What versions are currently installed
|
||||
3. **safe-update.sh**: How to update safely with rollback
|
||||
|
||||
This mirrors software engineering best practices (requirements → lockfile → deployment).
|
||||
|
||||
### Security Architecture
|
||||
**Defense in depth**:
|
||||
- **SSH key backup**: GPG-encrypted with restore instructions
|
||||
- **Git hooks**: Prevent accidental secret commits
|
||||
- **Firewall monitoring**: System health checks include security posture
|
||||
- **Sensitive data handling**: Never commit secrets, always encrypt backups
|
||||
|
||||
## Advanced Features
|
||||
|
||||
### Configuration Drift Detection
|
||||
**Problem**: Systems inevitably drift from their defined state
|
||||
**Solution**: Automated comparison between actual and intended configuration
|
||||
|
||||
**Three drift types monitored**:
|
||||
1. **Package drift**: Installed vs. Brewfile definitions
|
||||
2. **Configuration drift**: Live files vs. dotfiles repository
|
||||
3. **System drift**: Current macOS settings vs. defaults script
|
||||
|
||||
### System Health Monitoring
|
||||
**Observability philosophy**: "You can't manage what you can't measure"
|
||||
|
||||
**Monitored components**:
|
||||
- **Resources**: CPU, memory, disk usage with intelligent thresholds
|
||||
- **Services**: Critical tools (Homebrew, Git, Zsh, SSH) health status
|
||||
- **Packages**: Total count, outdated packages, broken installations
|
||||
- **Shell performance**: Load time and plugin count impact
|
||||
- **Network**: Internet, DNS, GitHub connectivity for development
|
||||
- **Security**: SSH keys, GPG keys, firewall status
|
||||
|
||||
### Context-Aware Behavior
|
||||
**Philosophy**: Tools should adapt to how you work
|
||||
|
||||
**Context detection**:
|
||||
```bash
|
||||
# Automatic context detection based on PWD
|
||||
detect_context() {
|
||||
case "$PWD" in
|
||||
*work*) CURRENT_CONTEXT="work" ;;
|
||||
*chamber*) CURRENT_CONTEXT="chamber" ;;
|
||||
*vault*) CURRENT_CONTEXT="vault" ;;
|
||||
*dotfiles*) CURRENT_CONTEXT="dotfiles" ;;
|
||||
*) CURRENT_CONTEXT="general" ;;
|
||||
esac
|
||||
}
|
||||
```
|
||||
|
||||
**Context-specific behaviors**:
|
||||
- **Work**: Enhanced productivity shortcuts, stricter security
|
||||
- **Chamber**: Creative workspace optimizations
|
||||
- **Vault**: Knowledge management integration (Obsidian shortcuts)
|
||||
- **Dotfiles**: System administration tools prominently available
|
||||
|
||||
## Error Handling Philosophy
|
||||
|
||||
### Graceful Degradation
|
||||
**Principle**: System remains functional when components fail
|
||||
|
||||
**Implementation patterns**:
|
||||
```bash
|
||||
# Tool availability checks
|
||||
if command -v fzf >/dev/null; then
|
||||
eval "$(fzf --zsh)"
|
||||
elif [[ -z "${P10K_INSTANT_PROMPT-}" ]]; then
|
||||
echo "⚠️ FZF not available - install with: brew install fzf"
|
||||
fi
|
||||
```
|
||||
|
||||
### Rollback Capabilities
|
||||
**Safe-update pattern**: Always create recovery points before changes
|
||||
- **Snapshots**: Package states and configuration backups
|
||||
- **Health testing**: Verify system function after updates
|
||||
- **Automatic rollback**: Return to last known good state on failure
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Shell Startup Optimization
|
||||
**Problem**: Plugin-heavy shells can have slow startup times
|
||||
**Solutions**:
|
||||
- **Instant prompt**: Powerlevel10k instant prompt for immediate responsiveness
|
||||
- **Conditional loading**: Only load tools that are actually installed
|
||||
- **Fast mode**: Non-interactive shells bypass expensive operations
|
||||
|
||||
### Plugin Management Strategy
|
||||
**Antidote over Oh My Zsh**: Faster, more reliable plugin management
|
||||
**Curated plugin list**: Only essential plugins, regularly audited
|
||||
**Performance monitoring**: Track shell load times and plugin impact
|
||||
|
||||
## Future Evolution
|
||||
|
||||
### Extensibility Points
|
||||
**Plugin architecture**: Additional modules can be added to `shell/` directory
|
||||
**Hook system**: Custom scripts can extend behavior at defined points
|
||||
**Context expansion**: New work environments easily added to context detection
|
||||
|
||||
### Maintenance Strategy
|
||||
**Regular audits**: Quarterly review of tools and configurations
|
||||
**Dependency tracking**: Monitor for deprecated packages or breaking changes
|
||||
**Documentation updates**: Architecture docs updated with any design changes
|
||||
|
||||
## Conclusion
|
||||
|
||||
This dotfiles system embodies the principle that **good tools become invisible**. By prioritizing durability, thoughtfulness, and proportionality, it creates a computing environment that supports focused work rather than demanding constant maintenance.
|
||||
|
||||
The μέτρον principle ensures that every component has the right measure of complexity - no more, no less - for its intended purpose. This creates a system that remains stable and usable across years of computing, embodying the prime directive of durable, thoughtful solutions.

~/dotfiles/scripts/detect-drift.sh # Full drift report
|
||||
~/dotfiles/scripts/detect-drift.sh --quiet # Silent check (for automation)
|
||||
```
|
||||
|
||||
## Core Commands
|
||||
|
||||
### System Maintenance Functions
|
||||
|
||||
#### `sysupdate()`
|
||||
Enhanced system update with safety features:
|
||||
```bash
|
||||
sysupdate # Interactive update with prompts
|
||||
sysupdate --force # Skip confirmation prompts
|
||||
sysupdate --backup # Create snapshot before updating
|
||||
```
|
||||
|
||||
**Features**:
|
||||
- Creates system snapshot before updates
|
||||
- Verifies critical tools after updates
|
||||
- Updates lockfile automatically
|
||||
- Provides rollback on failure
|
||||
|
||||
#### `deep_clean()`
|
||||
Comprehensive system cleanup:
|
||||
```bash
|
||||
deep_clean # Interactive cleanup
|
||||
deep_clean --aggressive # More thorough cleanup
|
||||
```
|
||||
|
||||
**What it cleans**:
|
||||
- Homebrew cache and old versions
|
||||
- System caches and logs
|
||||
- Development tool caches (npm, pip, etc.)
|
||||
- Temporary files and downloads
|
||||
|
||||
### Context-Aware Functions

|
||||
```bash
|
||||
today # Open today's note in Obsidian
|
||||
weekly # Open weekly planning note
|
||||
vf "search term" # Find files in vault
|
||||
vault # Navigate to vault directory
|
||||
```
|
||||
|
||||
#### Git Enhancements
|
||||
```bash
|
||||
gst # Enhanced git status with context
|
||||

## Scripts Directory
|
||||
|
||||
### Core Scripts
|
||||
|
||||
#### `generate-lockfile.sh`
|
||||
Creates version snapshots for reproducible installations:
|
||||
```bash
|
||||
~/dotfiles/scripts/generate-lockfile.sh
|
||||
```
|
||||
- Captures current package versions
|
||||
- Shows differences from previous lock
|
||||
- Essential for system reproducibility
|
||||
|
||||
#### `safe-update.sh`
|
||||
System update with rollback protection:
|
||||
```bash
|
||||
~/dotfiles/scripts/safe-update.sh
|
||||
```
|
||||
- Creates pre-update snapshot
|
||||
- Tests system health after updates
|
||||
- Automatic rollback on failure
|
||||
- Keeps audit trail of changes
|
||||
|
||||
#### `detect-drift.sh`
|
||||
Configuration consistency monitoring:
|
||||
```bash
|
||||
# Full drift analysis
|
||||
~/dotfiles/scripts/detect-drift.sh
|
||||
|
||||
# Quiet mode (for automation)
|
||||
~/dotfiles/scripts/detect-drift.sh --quiet
|
||||
|
||||
# View last report
|
||||
~/dotfiles/scripts/detect-drift.sh --report
|
||||
```
|
||||
|
||||
**Drift types detected**:
|
||||
- Package drift (installed vs. Brewfile)
|
||||
- Configuration drift (live vs. repository)
|
||||
- System settings drift (current vs. defaults)
|
||||
|
||||
#### `system-health.sh`
|
||||
System monitoring and observability:
|
||||
```bash
|
||||
# Dashboard view (default)
|
||||
~/dotfiles/scripts/system-health.sh
|
||||
|
||||
# Continuous monitoring
|
||||
~/dotfiles/scripts/system-health.sh monitor
|
||||
|
||||
# JSON output for automation
|
||||
~/dotfiles/scripts/system-health.sh json
|
||||
```
|
||||
|
||||
**Monitored components**:
|
||||
- System resources (CPU, memory, disk)
|
||||
- Critical services health
|
||||
- Package status
|
||||
- Network connectivity
|
||||
- Security posture
|
||||
|
||||
#### `backup-ssh-keys.sh`
|
||||
Secure backup of SSH keys:
|
||||
```bash
|
||||
~/dotfiles/scripts/backup-ssh-keys.sh
|
||||
```
|
||||
- GPG encryption of private keys
|
||||
- Generates restore instructions
|
||||
- Manages backup retention
|
||||
|
||||
## Shell Configuration
|
||||
|
||||
### Environment Variables
|
||||
Key environment variables set by the system:
|
||||
|
||||
```bash
|
||||
EDITOR=nvim # Default editor
|
||||
PAGER=less # Default pager
|
||||
BROWSER=open # Default browser (macOS)
|
||||
CURRENT_CONTEXT=detected # Current working context
|
||||
HOMEBREW_NO_ANALYTICS=1 # Privacy setting
|
||||
```
|
||||
|
||||
### PATH Management
|
||||
The system intelligently builds PATH from multiple sources:
|
||||
- Homebrew binaries (`/opt/homebrew/bin`)
|
||||
- User binaries (`~/.local/bin`)
|
||||
- System binaries (`/usr/local/bin`, `/usr/bin`)
|
||||
- Context-specific paths
|
||||
|
||||
PATH deduplication ensures no duplicates and optimal ordering.
|
||||
|
||||
### Plugin Management
|
||||
Plugins managed via Antidote from `shell/.zsh-plugins.txt`:
|
||||
```bash
|
||||
# Core plugins
|
||||
ohmyzsh/ohmyzsh path:plugins/git
|
||||
zsh-users/zsh-syntax-highlighting
|
||||
zsh-users/zsh-autosuggestions
|
||||
romkatv/powerlevel10k kind:fpath
|
||||
```
|
||||
|
||||
## Context-Aware Behavior
|
||||
|
||||
### Work Context
|
||||
**Triggered when**: PWD contains "work"
|
||||
**Features**:
|
||||
- Enhanced security prompts
|
||||
- Work-specific aliases
|
||||
- Stricter file permissions
|
||||
|
||||
### Chamber Context
|
||||
**Triggered when**: PWD contains "chamber"
|
||||
**Features**:
|
||||
- Creative workspace optimizations
|
||||
- Media tool shortcuts
|
||||
- Relaxed security for experimentation
|
||||
|
||||
### Vault Context
|
||||
**Triggered when**: PWD contains "vault"
|
||||
**Features**:
|
||||
- Obsidian integration shortcuts
|
||||
- Knowledge management tools
|
||||
- Quick note creation
|
||||
|
||||
### Dotfiles Context
|
||||
**Triggered when**: PWD contains "dotfiles"
|
||||
**Features**:
|
||||
- System administration tools
|
||||
- Enhanced git shortcuts
|
||||
- Configuration testing utilities
|
||||
|
||||
## Automation and Monitoring
|
||||
|
||||
### Automated Health Checks
|
||||
Set up automated monitoring with cron or launchd:
|
||||
```bash
|
||||
# Check drift daily (example crontab entry)
|
||||
0 9 * * * ~/dotfiles/scripts/detect-drift.sh --quiet || echo "Drift detected"
|
||||
|
||||
# Weekly health reports
|
||||
0 9 * * 1 ~/dotfiles/scripts/system-health.sh json > ~/health-$(date +\%Y\%m\%d).json
|
||||
```
|
||||
|
||||
### Integration with CI/CD
|
||||
Scripts return appropriate exit codes for automation:
|
||||
- `0`: Success/healthy
|
||||
- `1`: Warning/degraded
|
||||
- `2`: Error/unhealthy
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
#### Shell Not Loading Properly
|
||||
```bash
|
||||
# Check for syntax errors
|
||||
zsh -n ~/.zshrc
|
||||
|
||||
# Load with debugging
|
||||
zsh -x ~/.zshrc
|
||||
```
|
||||
|
||||
#### Missing Tools
|
||||
```bash
|
||||
# Install missing Homebrew packages
|
||||
brew bundle --file=~/dotfiles/Brewfile
|
||||
|
||||
# Check for available updates
|
||||
brew outdated
|
||||
```
|
||||
|
||||
#### Performance Issues
|
||||
```bash
|
||||
# Check shell load time
|
||||
time (zsh -i -c exit)
|
||||
|
||||
# Monitor system health
|
||||
~/dotfiles/scripts/system-health.sh monitor
|
||||
```
|
||||
|
||||
#### Configuration Drift
|
||||
```bash
|
||||
# Detect and fix drift
|
||||
~/dotfiles/scripts/detect-drift.sh
|
||||
|
||||
# Re-sync configurations
|
||||
~/dotfiles/engage config
|
||||
```
|
||||
|
||||
### Recovery Procedures
|
||||
|
||||
#### System Rollback
|
||||
If updates break the system:
|
||||
```bash
|
||||
# View available snapshots
|
||||
ls ~/.system-snapshots/
|
||||
|
||||
# Manual rollback (guided by snapshot contents)
|
||||
cat ~/.system-snapshots/TIMESTAMP/restore-instructions.txt
|
||||
```
|
||||
|
||||
#### Configuration Reset
|
||||
```bash
|
||||
# Backup current config
|
||||
cp ~/.zshrc ~/.zshrc.backup
|
||||
|
||||
# Restore from dotfiles
|
||||
ln -sf ~/dotfiles/shell/.zshrc ~/.zshrc
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
### Regular Maintenance
|
||||
```bash
|
||||
# Weekly routine
|
||||
sysupdate # Update packages
|
||||
~/dotfiles/scripts/detect-drift.sh # Check consistency
|
||||
deep_clean # Clean up cruft
|
||||
```
|
||||
|
||||
### Before Major Changes
|
||||
```bash
|
||||
# Create safety snapshot
|
||||
~/dotfiles/scripts/safe-update.sh
|
||||
|
||||
# Or manual snapshot
|
||||
cp -r ~/.config ~/.config.backup
|
||||
```
|
||||
|
||||
### Customization
|
||||
- Add machine-specific config to `~/.zshrc.local`
|
||||
- Add environment variables to `~/.env.local`
|
||||
- Never edit the main dotfiles directly for temporary changes
