Implements real-time audio visualization for the main page:
- Added Parenscript dependency to asteroid.asd
- Created spectrum-analyzer.lisp with Parenscript code
- Added canvas element to front-page.ctml above nav buttons
- Auto-generates JavaScript at compile time
- Green gradient bars matching Asteroid aesthetic
- Uses Web Audio API for FFT analysis
This is the first Parenscript component in Asteroid Radio,
demonstrating the approach for future JavaScript conversions.
The 'sequential' mode in Liquidsoap starts playback at a random position
in the playlist, causing tracks to play out of order. Switching to 'normal'
mode ensures the playlist starts from the beginning and plays sequentially
through all tracks in order.
- Change audio player background from #1a1a1a to #1a2332
- Matches the blue-grey color used throughout the app
- Addresses Fade's feedback about brownish grey appearance
- Change track link colors: cyan default, green hover, blue visited
- Add equal left/right padding (12px) to track-list for centered separators
- Increase track-item top/bottom padding from 6px to 10px for better spacing
- Move track-list and track-item inside recently-played-list block for proper CSS nesting
- Addresses feedback from easilok on symmetry and breathing room
- Move track-link styles inside recently-played-list block for proper CSS nesting
- Use (:and .track-link :hover) at correct nesting level per LASS documentation
- Fixes hover color change to green when mousing over track names
- Generates correct CSS selector: .recently-played-list .track-link:hover
- Replace separate MusicBrainz link with clickable track name
- Add external link icon next to track name
- Simplify grid layout by removing track-meta column
- Update CSS styling for track-link with hover effects
- Improves UX by making the primary action (clicking track) more intuitive
- Display last 3 played tracks on front page
- Auto-updates every 30 seconds
- Shows track title, artist, and time ago
- Links to MusicBrainz search for each track
- Thread-safe in-memory storage
- Works in both normal and frameset modes
- Hacker-themed green styling
Implements feature request from fade to show recently played tracks
with linkage to track info at music database.
- Add favicon.ico, favicon-16x16.png, and favicon-32x32.png
- Add asteroid.png graphic to header on both front-page.ctml and front-page-content.ctml
- Update header styling to display asteroid graphics flanking the station name
- Use 2-column grid layout: track/artist left, time/link right
- Match color scheme with now-playing section (blue text)
- Tighter row spacing (6px padding)
- Simplified MusicBrainz search query (no field prefixes)
- Fix CSS selector for proper link styling
- Right-align time and MusicBrainz link
- Display last 3 played tracks on front page
- Auto-updates every 30 seconds
- Shows track title, artist, and time ago
- Links to MusicBrainz search for each track
- Thread-safe in-memory storage
- Works in both normal and frameset modes
- Hacker-themed green styling

This fix some issues where, on the client, `response.message` was `Ok.`
for error responses and real error message needed to be extracted from
`response.data.message`, which made a weird API.
- Auto-detect music library path based on environment
- Check for music/library/ directory for local development
- Default to /app/music/ for production Docker deployment
- Allow MUSIC_LIBRARY_PATH environment variable override
- Fixes scan-library function failing on production server
- Changed hardcoded music/library/ path to /app/music/ (production path)
- Added MUSIC_LIBRARY_PATH environment variable for local dev override
- Fixes scan library function on production server
- Aligns with path structure used in M3U playlists and liquidsoap config
The previous commit used uri-path() which doesn't exist in Radiance.
This caused 'The function ASTEROID::URI-PATH is undefined' errors
when trying to authenticate.
Changed to use radiance:path() which is the correct Radiance API
function for extracting the path component from a URI object.
Fixes authentication in both require-authentication and require-role.
The playlist was stuck on the first track because mode='normal' stops
after playing once. Changed to mode='sequential' which plays through
the entire playlist in order and then loops.
Also improved reload mechanism:
- Use reload_mode='watch' for efficient file change detection
- Increased reload interval to 5 minutes (less disruptive)
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
