# Workspace Switching Guide

**Version**: 1.0.0
**Date**: 2025-10-06
**Status**: ✅ Production Ready

## Overview

The provisioning system now includes a centralized workspace management system that allows you to easily switch between multiple workspaces without manually editing configuration files.

## Quick Start

### List Available Workspaces

```bash
provisioning workspace list
```

Output:
```
Registered Workspaces:

  ● librecloud
      Path: /Users/Akasha/project-provisioning/workspace_librecloud
      Last used: 2025-10-06T12:29:43Z

    production
      Path: /opt/workspaces/production
      Last used: 2025-10-05T10:15:30Z
```

The green ● indicates the currently active workspace.

### Check Active Workspace

```bash
provisioning workspace active
```

Output:
```
Active Workspace:
  Name: librecloud
  Path: /Users/Akasha/project-provisioning/workspace_librecloud
  Last used: 2025-10-06T12:29:43Z
```

### Switch to Another Workspace

```bash
# Option 1: Using activate
provisioning workspace activate production

# Option 2: Using switch (alias)
provisioning workspace switch production
```

Output:
```
✓ Workspace 'production' activated

Current workspace: production
Path: /opt/workspaces/production

ℹ All provisioning commands will now use this workspace
```

### Register a New Workspace

```bash
# Register without activating
provisioning workspace register my-project ~/workspaces/my-project

# Register and activate immediately
provisioning workspace register my-project ~/workspaces/my-project --activate
```

### Remove Workspace from Registry

```bash
# With confirmation prompt
provisioning workspace remove old-workspace

# Skip confirmation
provisioning workspace remove old-workspace --force
```

**Note**: This only removes the workspace from the registry. The workspace files are NOT deleted.

## Architecture

### Central User Configuration

All workspace information is stored in a central user configuration file:

**Location**: `~/Library/Application Support/provisioning/user_config.yaml`

**Structure**:
```yaml
# Active workspace (current workspace in use)
active_workspace: "librecloud"

# Known workspaces (automatically managed)
workspaces:
  - name: "librecloud"
    path: "/Users/Akasha/project-provisioning/workspace_librecloud"
    last_used: "2025-10-06T12:29:43Z"

  - name: "production"
    path: "/opt/workspaces/production"
    last_used: "2025-10-05T10:15:30Z"

# User preferences (global settings)
preferences:
  editor: "vim"
  output_format: "yaml"
  confirm_delete: true
  confirm_deploy: true
  default_log_level: "info"
  preferred_provider: "upcloud"

# Metadata
metadata:
  created: "2025-10-06T12:29:43Z"
  last_updated: "2025-10-06T13:46:16Z"
  version: "1.0.0"
```

### How It Works

1. **Workspace Registration**: When you register a workspace, it's added to the `workspaces` list in `user_config.yaml`

2. **Activation**: When you activate a workspace:
   - `active_workspace` is updated to the workspace name
   - The workspace's `last_used` timestamp is updated
   - All provisioning commands now use this workspace's configuration

3. **Configuration Loading**: The config loader reads `active_workspace` from `user_config.yaml` and loads:
   - `workspace_path/config/provisioning.yaml`
   - `workspace_path/config/providers/*.toml`
   - `workspace_path/config/platform/*.toml`
   - `workspace_path/config/kms.toml`

## Advanced Features

### User Preferences

You can set global user preferences that apply across all workspaces:

```bash
# Get a preference value
provisioning workspace get-preference editor

# Set a preference value
provisioning workspace set-preference editor "code"

# View all preferences
provisioning workspace preferences
```

**Available Preferences**:
- `editor`: Default editor for config files (vim, code, nano, etc.)
- `output_format`: Default output format (yaml, json, toml)
- `confirm_delete`: Require confirmation for deletions (true/false)
- `confirm_deploy`: Require confirmation for deployments (true/false)
- `default_log_level`: Default log level (debug, info, warn, error)
- `preferred_provider`: Preferred cloud provider (aws, upcloud, local)

### Output Formats

List workspaces in different formats:

```bash
# Table format (default)
provisioning workspace list

# JSON format
provisioning workspace list --format json

# YAML format
provisioning workspace list --format yaml
```

### Quiet Mode

Activate workspace without output messages:

```bash
provisioning workspace activate production --quiet
```

## Workspace Requirements

For a workspace to be activated, it must have:

1. **Directory exists**: The workspace directory must exist on the filesystem

2. **Config directory**: Must have a `config/` directory
   ```
   workspace_name/
   └── config/
       ├── provisioning.yaml  # Required
       ├── providers/         # Optional
       ├── platform/          # Optional
       └── kms.toml           # Optional
   ```

3. **Main config file**: Must have `config/provisioning.yaml`

If these requirements are not met, the activation will fail with helpful error messages:

```
✗ Workspace 'my-project' not found in registry
💡 Available workspaces:
   [list of workspaces]
💡 Register it first with: provisioning workspace register my-project <path>
```

```
✗ Workspace is not migrated to new config system
💡 Missing: /path/to/workspace/config
💡 Run migration: provisioning workspace migrate my-project
```

## Migration from Old System

If you have workspaces using the old context system (`ws_{name}.yaml` files), they still work but you should register them in the new system:

```bash
# Register existing workspace
provisioning workspace register old-workspace ~/workspaces/old-workspace

# Activate it
provisioning workspace activate old-workspace
```

The old `ws_{name}.yaml` files are still supported for backward compatibility, but the new centralized system is recommended.

## Best Practices

### 1. **One Active Workspace at a Time**

Only one workspace can be active at a time. All provisioning commands use the active workspace's configuration.

### 2. **Use Descriptive Names**

Use clear, descriptive names for your workspaces:

```bash
# ✅ Good
provisioning workspace register production-us-east ~/workspaces/prod-us-east
provisioning workspace register dev-local ~/workspaces/dev

# ❌ Avoid
provisioning workspace register ws1 ~/workspaces/workspace1
provisioning workspace register temp ~/workspaces/t
```

### 3. **Keep Workspaces Organized**

Store all workspaces in a consistent location:

```bash
~/workspaces/
├── production/
├── staging/
├── development/
└── testing/
```

### 4. **Regular Cleanup**

Remove workspaces you no longer use:

```bash
# List workspaces to see which ones are unused
provisioning workspace list

# Remove old workspace
provisioning workspace remove old-workspace
```

### 5. **Backup User Config**

Periodically backup your user configuration:

```bash
cp "~/Library/Application Support/provisioning/user_config.yaml" \
   "~/Library/Application Support/provisioning/user_config.yaml.backup"
```

## Troubleshooting

### Workspace Not Found

**Problem**: `✗ Workspace 'name' not found in registry`

**Solution**: Register the workspace first:
```bash
provisioning workspace register name /path/to/workspace
```

### Missing Configuration

**Problem**: `✗ Missing workspace configuration`

**Solution**: Ensure the workspace has a `config/provisioning.yaml` file. Run migration if needed:
```bash
provisioning workspace migrate name
```

### Directory Not Found

**Problem**: `✗ Workspace directory not found: /path/to/workspace`

**Solution**:
1. Check if the workspace was moved or deleted
2. Update the path or remove from registry:
```bash
provisioning workspace remove name
provisioning workspace register name /new/path
```

### Corrupted User Config

**Problem**: `Error: Failed to parse user config`

**Solution**: The system automatically creates a backup and regenerates the config. Check:
```bash
ls -la "~/Library/Application Support/provisioning/user_config.yaml"*
```

Restore from backup if needed:
```bash
cp "~/Library/Application Support/provisioning/user_config.yaml.backup.TIMESTAMP" \
   "~/Library/Application Support/provisioning/user_config.yaml"
```

## Integration with Config System

The workspace switching system is fully integrated with the new target-based configuration system:

### Configuration Hierarchy (Priority: Low → High)

```
1. Workspace config      workspace/{name}/config/provisioning.yaml
2. Provider configs      workspace/{name}/config/providers/*.toml
3. Platform configs      workspace/{name}/config/platform/*.toml
4. User context          ~/Library/Application Support/provisioning/ws_{name}.yaml (legacy)
5. User config           ~/Library/Application Support/provisioning/user_config.yaml (new)
6. Environment variables PROVISIONING_*
```

### Example Workflow

```bash
# 1. Create and activate development workspace
provisioning workspace register dev ~/workspaces/dev --activate

# 2. Work on development
provisioning server create web-dev-01
provisioning taskserv create kubernetes

# 3. Switch to production
provisioning workspace switch production

# 4. Deploy to production
provisioning server create web-prod-01
provisioning taskserv create kubernetes

# 5. Switch back to development
provisioning workspace switch dev

# All commands now use dev workspace config
```
