Frameset mode now works correctly with:
- Persistent audio across all navigation via AJAX
- Spectrum analyzer MUTED indicator working
- Now Playing panel updates (200ms delay)
- Interval cleanup before navigation
- Cache-control headers for player.js
Fixed issues:
- Replace all == operators with equal in player.lisp
- Add defvar instead of let in redirect-when-frame
- Add interval/timeout cleanup before AJAX navigation
- Fix spectrum analyzer re-initialization after navigation
- Add cache-busting headers for JavaScript
Known issue:
- Non-frameset mode has ParenScript compilation issue
- Only 15/36 functions compile due to parenthesis imbalance
- Frameset mode is the recommended interface for persistent audio
Files modified:
- asteroid.lisp: Add cache-control headers
- parenscript/player.lisp: Fix == operators, fix redirect-when-frame
- template/*-content.ctml: Add AJAX navigation and interval cleanup
- template/status-content.ctml: Created placeholder
- parenscript/spectrum-analyzer.lisp: Fix re-initialization
Major Changes:
- Convert all JavaScript files to Parenscript for better maintainability
- Move spectrum-analyzer to parenscript/ directory structure
- Add parenscript-utils.lisp for shared utilities
- Convert admin.js, player.js, front-page.js, auth-ui.js to Parenscript
- Convert profile.js, users.js, recently-played.js to Parenscript
Stream Reconnect Fixes (from merged PR):
- Add reset-spectrum-analyzer function to properly clean up Web Audio API
- Implement reconnect logic for pauses longer than 10 seconds
- Detect stale audio in 'playing' event and force stream reconnection
- Prevent 'Now Playing' updates while stream is paused
- Reduce reconnect delay to 200ms for faster response
- Add proper spectrum analyzer reset/reinit during reconnection
UX Improvements:
- Change live indicator from blink to smooth pulse (2s ease-in-out)
- Pulse animation like old PowerBook/MacBook sleep indicator
- Add MUTED indicator to spectrum analyzer when audio is muted
- Spectrum continues to flow even when muted (data still streaming)
- Red 'MUTED' text displayed in top-right corner of canvas
Technical Details:
- Parenscript files generate JavaScript via API endpoints
- All player modes updated: main player, front page, popout, frame player
- Improved audio context handling to only create once per element
- Added comprehensive error handling and logging
- Updated asteroid.asd to include parenscript module structure
Documentation:
- Updated all documentation dates to 2025-12-06
- Added PARENSCRIPT-EXPERIMENT.org documenting the conversion
- Updated PROJECT-HISTORY.org with Phase 9 (Visual Audio Features)
- Added comprehensive project statistics (408 commits, 9,300 LOC)
This conversion improves code maintainability by using Lisp throughout
the stack and makes it easier to share code between frontend and backend.
