Story 3.2: Permission Code Generation System

Metadata

Story ID: 3.2
Title: Permission Code Generation System
Epic: 3 - Module Framework
Status: Pending
Priority: High
Estimated Time: 4-5 hours
Dependencies: 3.1

Goal

Create automated permission code generation from module manifests to ensure type-safe permission constants.

Description

This story implements a code generation system that scans module manifests and generates type-safe permission constants, ensuring permissions are defined in one place and used consistently throughout the codebase.

Deliverables

1. Permission Generation Script (`scripts/generate-permissions.go`)

Scan all modules/*/module.yaml files
Extract permissions from manifests
Generate pkg/perm/generated.go with Permission constants
Support for multiple modules
Error handling and validation
Format generated code

2. Go Generate Integration

//go:generate directive in pkg/perm/perm.go
Automatic generation on build
Integration with build process

3. Makefile Integration

make generate command
Run permission generation
Verify generated code

Implementation Steps

Create Generation Script
- Create scripts/generate-permissions.go
- Implement YAML parsing
- Implement code generation
Add Go Generate Directive
- Add directive to pkg/perm/perm.go
- Test generation
Update Makefile
- Add make generate command
- Integrate with build process

Acceptance Criteria

Permission constants are generated from module.yaml
Generated code is type-safe
Code generation runs automatically
Permissions follow naming convention
Multiple modules are supported
Generated code is properly formatted

Files to Create/Modify

scripts/generate-permissions.go - Generation script
pkg/perm/perm.go - Add go:generate directive
Makefile - Add generate command
