refactor: Implement Lispy improvements - templates, strings, and error handling
This commit implements three major refactorings to make the codebase more
idiomatic and maintainable:
1. Template Path Centralization
- Add *template-directory* parameter and helper functions
- Replace 11+ instances of repetitive template loading boilerplate
- New functions: template-path, load-template in template-utils.lisp
2. String Construction with FORMAT
- Replace concatenate with format for external URLs (Icecast, static files)
- Maintain Radiance URI handling for internal routes
- Applied to stream URLs, status endpoints, and API responses
3. Error Handling with Custom Conditions
- NEW FILE: conditions.lisp with comprehensive error hierarchy
- Custom conditions: not-found-error, authentication-error,
authorization-error, validation-error, database-error, asteroid-stream-error
- Helper macros: with-error-handling, with-db-error-handling
- Helper functions: signal-not-found, signal-validation-error, etc.
- Refactored 19 API endpoints and page routes
- Proper HTTP status codes: 404, 401, 403, 400, 500
Changes:
- conditions.lisp: NEW (180+ lines of error handling infrastructure)
- asteroid.asd: Add conditions.lisp to system components
- asteroid.lisp: Refactor 30+ endpoints, eliminate 200+ lines of boilerplate
- template-utils.lisp: Add centralized template loading helpers
- frontend-partials.lisp: Update template loading and string construction
Net result: -97 lines of code, significantly improved error handling,
more maintainable and idiomatic Common Lisp.
All changes tested and verified:
- Clean build
- All endpoints functional
- Error handling returns proper HTTP codes
- No regressions
