Workspace Configuration Implementation Summary

Date: 2025-10-06 Agent: workspace-structure-architect Status: ✅ Complete

3. Config Loader Modifications ✅

Location: /Users/Akasha/project-provisioning/provisioning/core/nulib/lib_provisioning/config/loader.nu

Critical Changes

❌ REMOVED: get-defaults-config-path()

The old function that loaded config.defaults.toml has been completely removed and replaced with:

✅ ADDED: get-active-workspace()

def get-active-workspace [] {
    # Finds active workspace from user config
    # Returns: {name: string, path: string} or null
}

New Loading Hierarchy

OLD (Removed):

1. config.defaults.toml (System)
2. User config.toml
3. Project provisioning.toml
4. Infrastructure .provisioning.toml
5. Environment variables

NEW (Implemented):

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

Function Updates

load-provisioning-config
- Now uses get-active-workspace() instead of get-defaults-config-path()
- Loads workspace YAML config
- Merges provider and platform configs
- Applies user context
- Environment variables as final override
load-config-file
- Added support for YAML format
- New parameter: format: string = "auto"
- Auto-detects format from extension (.yaml, .yml, .toml)
- Handles both YAML and TOML parsing
Config sources building
- Dynamically builds config sources based on active workspace
- Loads all provider configs from workspace/config/providers/
- Loads all platform configs from workspace/config/platform/
- Includes user context as highest config priority

Fallback Behavior

If no active workspace:

Checks PWD for workspace config
If found, loads it
If not found, errors: “No active workspace found”

4. Documentation Created ✅

5. Confirmation: config.defaults.toml is NOT Loaded ✅

Evidence

Function Removed: get-defaults-config-path() completely removed from loader.nu
New Function: get-active-workspace() replaces it
No References: config.defaults.toml is NOT in any config source paths
Template Only: File exists only as template reference

Loading Path Verification

# OLD (REMOVED):
let config_path = (get-defaults-config-path)  # Would load config.defaults.toml

# NEW (IMPLEMENTED):
let active_workspace = (get-active-workspace)  # Loads from user context
let workspace_config = "{workspace}/config/provisioning.yaml"  # Main config

Critical Confirmation

config.defaults.toml:

✅ Exists as template only
✅ Used to generate workspace configs
✅ NEVER loaded at runtime
✅ NEVER in config sources list
✅ NEVER accessed by config loader

System Architecture

Before (Old System)

config.defaults.toml → load-provisioning-config → Runtime Config
         ↑
    LOADED AT RUNTIME (❌ Anti-pattern)

After (New System)

Templates → workspace-init → Workspace Config → load-provisioning-config → Runtime Config
              (generation)        (stored)              (loaded)

config.defaults.toml: TEMPLATE ONLY, NEVER LOADED ✅

Usage Examples

Initialize Workspace

use provisioning/core/nulib/lib_provisioning/workspace/init.nu *

workspace-init "production" "/workspaces/prod" \
  --providers ["aws" "upcloud"] \
  --activate

List Workspaces

workspace-list
# Output:
# ┌──────────────┬─────────────────────┬────────┐
# │ name         │ path                │ active │
# ├──────────────┼─────────────────────┼────────┤
# │ production   │ /workspaces/prod    │ true   │
# │ development  │ /workspaces/dev     │ false  │
# └──────────────┴─────────────────────┴────────┘

Activate Workspace

workspace-activate "development"
# Output: ✅ Activated workspace: development

Get Active Workspace

workspace-get-active
# Output: {name: "development", path: "/workspaces/dev"}

Key Achievements

✅ Template-Only Architecture: config.defaults.toml is NEVER loaded at runtime
✅ Workspace-Based Config: Each workspace has complete, self-contained configuration
✅ Template System: 6 templates for generating workspace configs
✅ Workspace Management: Full suite of workspace init/list/activate/get functions
✅ New Config Loader: Complete rewrite with workspace-first approach
✅ YAML Support: Main config is now YAML, providers/platform are TOML
✅ User Context: Per-workspace user overrides in ~/Library/Application Support/
✅ Documentation: Comprehensive docs for architecture and usage
✅ Clear Hierarchy: Predictable config loading order
✅ Security: .gitignore for sensitive files, KMS key management

Migration Path

For Existing Users

Initialize workspace from existing infra:

workspace-init "my-infra" "/path/to/existing/infra" --activate

Copy existing settings to workspace config:

# Manually migrate settings from ENV to workspace/config/provisioning.yaml

Update scripts to use workspace commands:

# OLD: export PROVISIONING=/path
# NEW: workspace-activate "my-workspace"

Validation

Config Loader Test

# Test that config.defaults.toml is NOT loaded
use provisioning/core/nulib/lib_provisioning/config/loader.nu *

let config = (load-provisioning-config --debug)
# Should load from workspace, NOT from config.defaults.toml

Template Generation Test

# Test template generation
use provisioning/core/nulib/lib_provisioning/workspace/init.nu *

workspace-init "test-workspace" "/tmp/test-ws" --providers ["local"] --activate
# Should generate all configs from templates

Workspace Activation Test

# Test workspace activation
workspace-list  # Should show test-workspace as active
workspace-get-active  # Should return test-workspace

Next Steps (Future Work)

CLI Integration: Add workspace commands to main provisioning CLI
Migration Tool: Automated ENV → workspace migration
Workspace Templates: Pre-configured templates (dev, prod, test)
Validation Commands: provisioning workspace validate
Import/Export: Share workspace configurations
Remote Workspaces: Load from Git repositories

Summary

The workspace configuration architecture has been successfully implemented with the following guarantees:

✅ config.defaults.toml is ONLY a template, NEVER loaded at runtime ✅ Each workspace has its own provisioning.yaml as main config ✅ Templates generate complete workspace structure ✅ Config loader uses new workspace-first hierarchy ✅ User context provides per-workspace overrides ✅ Comprehensive documentation provided

The system is now ready for workspace-based configuration management, eliminating the anti-pattern of loading template files at runtime.
