Issue 017: Implement Image Integration System

Current Behavior

  • Image directories are configured but not integrated with poem pages
  • No image discovery or cataloging system
  • Missing image file management and directory scanning

Intended Behavior

  • Discover and catalog all images from configured directories
  • Integrate image management with existing poem processing pipeline
  • Provide foundation for image placement algorithms

Suggested Implementation Steps

  1. Image Discovery: Scan configured directories for supported image formats
  2. Cataloging System: Create image metadata database with paths and attributes
  3. Integration: Connect image system with poem extraction pipeline
  4. Configuration: Set up image directory paths and file type filters

Dependencies

  • Issue 026: Scripts directory integration (for extracting images from ZIP archives)

Quality Assurance Criteria

  • All images in configured directories are discovered and cataloged
  • Image metadata includes necessary information for placement algorithms
  • System integrates cleanly with existing poem processing workflow

ISSUE STATUS: IN PROGRESS 🔄🖼️

Priority: Low - Enhancement for additional image directories

🔄 Enhancement Phase: Additional Image Directories

Current Enhancement Work

  • Status: User implementing script for additional image directories
  • Priority: Low - Enhancement to existing working system
  • Target: Dynamic discovery of ${DIR}/input/images/${NAME} directories

Additional Considerations

1. Dynamic Directory Discovery

-- {{{ function discover_additional_image_directories
local function discover_additional_image_directories(base_input_dir)
    local image_base_dir = base_input_dir .. "/images"
    local additional_dirs = {}
    
    -- Check if input/images directory exists
    local check_cmd = string.format("test -d '%s'", image_base_dir)
    local exists = os.execute(check_cmd) == true or os.execute(check_cmd) == 0
    
    if not exists then
        return additional_dirs
    end
    
    -- Scan for subdirectories in input/images/
    local find_cmd = string.format("find '%s' -maxdepth 1 -type d", image_base_dir)
    local handle = io.popen(find_cmd)
    
    for dir_path in handle:lines() do
        -- Skip the base images directory itself
        if dir_path ~= image_base_dir then
            local dir_name = dir_path:match("([^/]+)$")
            if dir_name then
                local relative_path = "input/images/" .. dir_name
                table.insert(additional_dirs, {
                    name = dir_name,
                    path = relative_path,
                    full_path = dir_path
                })
            end
        end
    end
    handle:close()
    
    return additional_dirs
end
-- }}}

2. Configuration Integration Enhancement

-- Enhanced configuration loading with dynamic directory discovery
function load_config_with_dynamic_directories()
    local config = load_config()  -- Load existing config
    
    -- Discover additional image directories
    local additional_dirs = discover_additional_image_directories(DIR .. "/input")
    
    -- Add discovered directories to image_directories array
    for _, dir_info in ipairs(additional_dirs) do
        table.insert(config.image_directories, dir_info.path)
        print("🔍 Auto-discovered image directory: " .. dir_info.name)
    end
    
    return config
end

3. Metadata Enhancement for Additional Directories

-- Enhanced image entry with source directory information
local image_entry = {
    file_path = file_path,
    relative_path = file_path:gsub("^" .. DIR .. "/", ""),
    filename = file_path:match("([^/]+)$"),
    extension = file_path:match("%.([^%.]+)$"):lower(),
    size_bytes = file_size,
    size_mb = math.floor(file_size / 1024 / 1024 * 100) / 100,
    width = width,
    height = height,
    aspect_ratio = (width and height) and (width / height) or nil,
    hash = file_hash,
    modification_time = mtime,
    modification_date = os.date("%Y-%m-%dT%H:%M:%SZ", mtime),
    source_directory = directory,
    -- Enhanced metadata for additional directories
    source_type = determine_source_type(directory),  -- "media_attachments", "additional", "docs"
    directory_name = directory:match("input/images/([^/]+)") or "core"
}

4. Statistics Enhancement

-- Enhanced statistics with directory breakdown
local stats = {
    total_images = #images,
    unique_images = #images - duplicate_count,
    duplicate_images = duplicate_count,
    total_size_mb = 0,
    average_size_mb = 0,
    format_distribution = {},
    size_distribution = {
        small = 0,    -- < 100KB
        medium = 0,   -- 100KB - 1MB
        large = 0     -- > 1MB
    },
    resolution_distribution = {
        low = 0,      -- < 500px width
        medium = 0,   -- 500-1500px width  
        high = 0      -- > 1500px width
    },
    -- Enhanced: directory source breakdown
    directory_distribution = {},  -- Count per source directory
    source_type_distribution = {} -- Count by source type (media_attachments, additional, docs)
}

5. Configuration File Enhancement

{
  "image_integration": {
    "enabled": true,
    "image_directories": [
      "input/extract/media_attachments",
      "input/fediverse/media_attachments", 
      "input/messages/media_attachments",
      "input/notes/media_attachments",
      "docs"
    ],
    "auto_discover_additional_dirs": true,
    "additional_dirs_pattern": "input/images/*",
    "supported_formats": ["png", "jpg", "jpeg", "gif", "webp", "svg"],
    "max_file_size_mb": 10,
    "output_path": "assets/images",
    "catalog_file": "assets/image-catalog.json"
  }
}

6. Integration Points

  • Discovery Timing: Run dynamic discovery before main image scanning
  • Logging Enhancement: Report discovered additional directories
  • Error Handling: Graceful handling of inaccessible additional directories
  • Performance: Efficient scanning for large numbers of additional directories

7. Future Considerations

  • Directory Filtering: Option to exclude specific directories by pattern
  • Recursive Discovery: Support for nested directory structures under input/images/
  • Directory Metadata: Track creation dates and statistics per additional directory
  • Configuration Override: Allow manual specification to override auto-discovery

Implementation Notes

  • Maintain backward compatibility with existing configuration
  • Ensure additional directories don't break existing functionality
  • Provide clear logging for discovered vs configured directories
  • Support graceful degradation if input/images/ doesn't exist
