Virtual Library Implementation

The virtual library system creates a seamless integration between Kobo’s native kepub collection and KOReader’s file browser, allowing users to access their Kobo library without switching between reading applications.

Overview

The virtual library implementation consists of several key components:

1. Metadata Parser (src/metadata_parser.lua) - Reads Kobo’s SQLite database to retrieve book metadata
2. Virtual Filesystem (src/filesystem_ext.lua) - Provides filesystem operations for virtual paths
3. File Chooser Extensions (src/filechooser_ext.lua) - Integrates the virtual library into KOReader’s file browser

Key Features

• Automatic Discovery: Scans Kobo’s kepub directory and matches files with database metadata
• DRM Detection: Identifies encrypted books to prevent access errors
• Metadata Integration: Displays book titles, authors, and cover images from Kobo’s database
• Transparent Access: Books appear as regular files in KOReader’s file browser
