Overview

This devlog covers the latest feature additions and bug fixes to VIBE IDE, including music player enhancements, code implementation improvements, and comprehensive documentation.

🎵 Music Player Features

Favorites System

Added a favorites system to Cursy’s Corner Music Player, allowing users to star tracks for quick access.

Implementation:

// Toggle favorite functionality
const handleAddToFavorites = () => {
    if (!songInfo) return;
    
    const favorites = JSON.parse(localStorage.getItem('sid_favorites') || '[]');
    const favorite = {
        name: songInfo.name,
        author: songInfo.author,
        path: sidPath,
        addedAt: Date.now(),
    };
    
    if (favorites.some(f => f.path === sidPath)) {
        // Remove from favorites
        const filtered = favorites.filter(f => f.path !== sidPath);
        localStorage.setItem('sid_favorites', JSON.stringify(filtered));
    } else {
        // Add to favorites
        favorites.push(favorite);
        localStorage.setItem('sid_favorites', JSON.stringify(favorites));
    }
};

Features:

• Star button to toggle favorites
• Persistent storage in localStorage
• Separate favorites for music and SFX
• Quick access via “⭐ Favorites” button

Playlist System

Implemented custom playlist functionality, allowing users to create, manage, and organize their own playlists.

Implementation:

// Create new playlist
function createPlaylist(name) {
    const playlists = JSON.parse(localStorage.getItem('music_playlists') || '[]');
    const newPlaylist = {
        id: Date.now().toString(),
        name: name,
        tracks: [],
        createdAt: Date.now()
    };
    playlists.push(newPlaylist);
    localStorage.setItem('music_playlists', JSON.stringify(playlists));
    return newPlaylist;
}

// Add track to playlist
function addTrackToPlaylist(playlistId, track) {
    const playlists = JSON.parse(localStorage.getItem('music_playlists') || '[]');
    const playlist = playlists.find(p => p.id === playlistId);
    if (playlist && !playlist.tracks.some(t => t.path === track.path)) {
        playlist.tracks.push(track);
        localStorage.setItem('music_playlists', JSON.stringify(playlists));
    }
}

Features:

• Create custom playlists
• Add/remove tracks
• Delete playlists
• Persistent storage in localStorage

🎧 Music & SFX Panel Improvements

Custom Audio Player

Replaced native HTML5 audio controls with custom-styled audio players for better UX and visual consistency.

Implementation:

// Custom audio player initialization
function initializeCustomAudioPlayers() {
    const players = document.querySelectorAll('.custom-audio-player');
    
    players.forEach(player => {
        const audio = player.querySelector('audio');
        const playBtn = player.querySelector('.play-pause-btn');
        const progressBar = player.querySelector('.progress-bar');
        const progressFill = player.querySelector('.progress-fill');
        const currentTime = player.querySelector('.current-time');
        const duration = player.querySelector('.duration');
        const volumeSlider = player.querySelector('.volume-slider');
        
        // Play/pause toggle
        playBtn.addEventListener('click', () => {
            if (audio.paused) {
                // Stop all other audio players
                document.querySelectorAll('.custom-audio-player audio').forEach(a => {
                    if (a !== audio) a.pause();
                });
                audio.play();
                playBtn.textContent = '⏸️';
            } else {
                audio.pause();
                playBtn.textContent = '▶️';
            }
        });
        
        // Progress bar update
        audio.addEventListener('timeupdate', () => {
            const percent = (audio.currentTime / audio.duration) * 100;
            progressFill.style.width = percent + '%';
            currentTime.textContent = formatTime(audio.currentTime);
        });
        
        // Volume control
        volumeSlider.addEventListener('input', (e) => {
            audio.volume = e.target.value / 100;
        });
    });
}

Features:

• Custom play/pause button
• Visual progress bar with time display
• Volume slider
• Auto-stop previous track when new one starts
• Consistent styling with VIBE IDE theme

Panel Animation Fix

Fixed the Music & SFX panel to slide up smoothly from the bottom instead of appearing in place.

CSS Fix:

.music-sfx-panel {
    position: fixed;
    bottom: 0;
    left: 0;
    right: 0;
    height: 60vh;
    background: #252526;
    border-top: 2px solid #8b5cf6;
    transform: translateY(100%);
    transition: transform 0.3s ease-in-out;
    visibility: hidden;
    z-index: 1000;
}

.music-sfx-panel.open {
    transform: translateY(0);
    visibility: visible;
}

Changes:

• Initial state: translateY(100%) (hidden below viewport)
• Open state: translateY(0) (visible)
• Smooth transition animation
• Proper visibility handling

💻 Code Implementation Improvements

“Implement All” Button Fix

Fixed critical bug where “Implement All” button only implemented the first file and then crashed.

Problem:

• implementCode() was clearing window.pendingImplementations after each file
• implementAllCode() tried to loop through null, causing crash

Solution:

// Implement all code blocks
window.implementAllCode = async function() {
    if (!window.pendingImplementations || window.pendingImplementations.length === 0) {
        console.warn('⚠️ No pending implementations to implement');
        return;
    }
    
    // Store copy BEFORE starting (since implementCode clears it)
    const implementations = [...window.pendingImplementations];
    const count = implementations.length;
    
    console.log(`✨ Implementing all ${count} code block(s)...`);
    
    // Set flag so implementCode knows we're in batch mode
    window.implementingAll = true;
    
    try {
        for (let i = 0; i < count; i++) {
            // Restore pendingImplementations for each call
            window.pendingImplementations = implementations;
            await window.implementCode(i);
            // Small delay between implementations
            await new Promise(resolve => setTimeout(resolve, 300));
        }
        
        // Remove implementation offer after all files are done
        const offers = document.querySelectorAll('.implementation-offer');
        offers.forEach(offer => offer.remove());
        
        console.log(`✅ All ${count} code block(s) implemented!`);
    } catch (err) {
        console.error('Error implementing all code blocks:', err);
    } finally {
        // Clear flag and pending implementations
        window.implementingAll = false;
        window.pendingImplementations = null;
    }
};

Key Changes:

• Store copy of implementations array before loop
• Set implementingAll flag to prevent premature clearing
• Restore pendingImplementations for each iteration
• Clear only after all files are implemented

Journal Update After Implementation

Enhanced journal update detection to work when requested after code implementation.

Problem:

• Journal update patterns only matched at start of message (^)
• “then update journal” at end wasn’t detected
• Journal content was output in chat instead of updating file

Solution:

// Enhanced journal update patterns
const journalUpdatePatterns = [
    /^(cursy[,]?\s*)?(can\s+you\s+|please\s+|will\s+you\s+)?(update|refresh|regenerate)\s+(the\s+)?(project\s+)?journal/i, // At start
    /^(update|refresh|regenerate)\s+(the\s+)?(project\s+)?journal(\s+please|\s+cursy)?/i, // At start
    /^(project\s+)?journal\s+(update|refresh|regenerate)/i, // At start
    /\b(then|and|also)\s+(update|refresh|regenerate)\s+(the\s+)?(project\s+)?journal/i, // "then update journal" anywhere
    /\b(update|refresh|regenerate)\s+(the\s+)?(project\s+)?journal\s*$/i // "update journal" at end
];

// Detect if both implementation and journal update requested
const isImplementationRequest = messageMarkdown.toLowerCase().match(/\b(implement|create|write|setup|set up)\b/) && 
                                (messageMarkdown.toLowerCase().includes('file') || 
                                 messageMarkdown.toLowerCase().includes('code') || 
                                 messageMarkdown.toLowerCase().includes('webpage'));

const isJournalUpdateCommand = journalUpdatePatterns.some(pattern => pattern.test(messageLower));
const shouldUpdateJournalAfter = isJournalUpdateCommand && isImplementationRequest;

// After code implementation completes
if (shouldUpdateJournalAfter) {
    setTimeout(async () => {
        await triggerJournalUpdate();
    }, 500);
}

Key Changes:

• Added patterns for “then update journal” and “update journal” at end
• Detect when both implementation and journal update are requested
• Trigger journal update after implementation completes
• Extracted journal update logic into reusable triggerJournalUpdate() function

🔧 Technical Details

Storage Structure

Favorites:

// Music favorites
localStorage.getItem('music_favorites') // Array of track objects

// SFX favorites  
localStorage.getItem('sfx_favorites') // Array of track objects

// SID favorites (legacy)
localStorage.getItem('sid_favorites') // Array of track objects

Playlists:

localStorage.getItem('music_playlists') // Array of playlist objects
// Each playlist: { id, name, tracks[], createdAt }

Function Calling Integration

Implemented OpenAI function calling for structured code blocks:

// Function definition in main.js
const tools = [{
    type: "function",
    function: {
        name: "provide_code_block",
        description: "Provide code blocks for file implementation",
        parameters: {
            type: "object",
            properties: {
                filePath: { type: "string" },
                language: { type: "string" },
                code: { type: "string" }
            },
            required: ["filePath", "code"]
        }
    }
}];

This ensures reliable code extraction and supports multiple files per response.
