#+TITLE: UI Fixes and Improvements - Complete
#+AUTHOR: Asteroid Radio Development Team
#+DATE: 2025-10-04

* Overview

Comprehensive UI fixes and improvements across all pages, including live stream indicators, stream quality display, and Now Playing functionality.

* What Was Completed

** Live Stream Indicators
Fixed red/green indicator inconsistencies across all pages

*** Front Page
- Changed =🔴 LIVE STREAM= to =🟢 LIVE STREAM=
- Added green color styling: =style="color: #00ff00;"=
- Status indicator shows =● BROADCASTING= in green

*** Web Player
- Changed =🔴 Live Radio Stream= to =🟢 Live Radio Stream=
- Consistent green indicator
- Matches front page styling

** Stream Quality Display

*** Problem Fixed
Stream quality showed "128kbps MP3" even when AAC stream was selected

*** Solution Implemented
- Updated default to "AAC 96kbps Stereo"
- Added JavaScript to sync quality display with selected stream
- Quality updates dynamically when user changes streams

*** Implementation
#+BEGIN_SRC javascript
function changeStreamQuality() {
  const selector = document.getElementById('stream-quality');
  const config = streamConfig[selector.value];
  
  // Update Station Status stream quality display
  const statusQuality = document.querySelector('[data-text="stream-quality"]');
  if (statusQuality) {
    statusQuality.textContent = config.format;
  }
  
  // Update stream URL and format
  document.getElementById('stream-url').textContent = config.url;
  document.getElementById('stream-format').textContent = config.format;
  
  // Update audio player
  const audioElement = document.getElementById('live-audio');
  const sourceElement = document.getElementById('audio-source');
  
  sourceElement.src = config.url;
  sourceElement.type = config.type;
  audioElement.load();
}
#+END_SRC

*** Page Load Initialization
#+BEGIN_SRC javascript
window.addEventListener('DOMContentLoaded', function() {
  // Set initial quality display to match the selected stream
  const selector = document.getElementById('stream-quality');
  const config = streamConfig[selector.value];
  
  document.getElementById('stream-url').textContent = config.url;
  document.getElementById('stream-format').textContent = config.format;
  
  const statusQuality = document.querySelector('[data-text="stream-quality"]');
  if (statusQuality) {
    statusQuality.textContent = config.format;
  }
});
#+END_SRC

** Now Playing Functionality

*** Investigation Results
- No HTML rendering bug found (was a false alarm in TODO)
- Now Playing working correctly on all pages
- Updates every 10 seconds from Icecast
- Proper text content rendering (no HTML injection)

*** Implementation Details
#+BEGIN_SRC javascript
function updateNowPlaying() {
  fetch('/asteroid/api/icecast-status')
    .then(response => response.json())
    .then(data => {
      if (data.icestats && data.icestats.source) {
        const mainStream = data.icestats.source;
        
        if (mainStream.title) {
          // Parse "Artist - Track" format
          const titleParts = mainStream.title.split(' - ');
          const artist = titleParts.length > 1 ? titleParts[0] : 'Unknown Artist';
          const track = titleParts.length > 1 ? titleParts.slice(1).join(' - ') : mainStream.title;
          
          // Use textContent to prevent HTML injection
          document.querySelector('[data-text="now-playing-artist"]').textContent = artist;
          document.querySelector('[data-text="now-playing-track"]').textContent = track;
          document.querySelector('[data-text="listeners"]').textContent = mainStream.listeners || '0';
        }
      }
    })
    .catch(error => console.log('Could not fetch stream status:', error));
}

// Update every 10 seconds
updateNowPlaying();
setInterval(updateNowPlaying, 10000);
#+END_SRC

** API Endpoint Fixes

*** Missing /api/tracks Endpoint
Created endpoint for web player to fetch tracks

#+BEGIN_SRC lisp
(define-page api-tracks #@"/api/tracks" ()
  "Get all tracks for web player"
  (require-authentication)
  (setf (radiance:header "Content-Type") "application/json")
  (handler-case
      (let ((tracks (db:select "tracks" (db:query :all))))
        (cl-json:encode-json-to-string
         `(("status" . "success")
           ("tracks" . ,(mapcar (lambda (track)
                                  `(("id" . ,(gethash "_id" track))
                                    ("title" . ,(gethash "title" track))
                                    ("artist" . ,(gethash "artist" track))
                                    ("album" . ,(gethash "album" track))
                                    ("duration" . ,(gethash "duration" track))
                                    ("format" . ,(gethash "format" track))))
                                tracks)))))
    (error (e)
      (cl-json:encode-json-to-string
       `(("status" . "error")
         ("message" . ,(format nil "Error retrieving tracks: ~a" e)))))))
#+END_SRC

*** Icecast Status Endpoint
Improved XML parsing for better reliability

#+BEGIN_SRC lisp
;; Extract title using register groups for cleaner extraction
(title (multiple-value-bind (match groups)
          (cl-ppcre:scan-to-strings "<title>(.*?)</title>" source-section)
        (if (and match (> (length groups) 0))
            (aref groups 0)
            "Unknown")))
