disk-canvas 0.1.1

A command-line tool to visualize disk usage as a treemap-inspired ASCII mosaic

disk-canvas

A command-line tool to visualize disk usage as a treemap-inspired ASCII mosaic. It scans a directory and produces a mosaic of uniformly sized, color-coded blocks based on file size and category. The visualization is designed to work on Linux and macOS.

Features

• ASCII Mosaic Visualization: A terminal-friendly mosaic that offers a quick visual summary of disk usage.
• Color-Coded Output: Uses a modern Plotly-inspired color palette.
• Multiple Modes: Detailed mode with a legend mapping file extensions, or a simplified mode grouping files by category.
• Cross-Platform: Works on Linux and macOS.
• Smart File Categorization: Automatically categorizes files into:
  • Code (Python, Java, JavaScript, etc.)
  • Notebooks (Jupyter, R Markdown)
  • Data (CSV, JSON, SQL, etc.)
  • Compressed (ZIP, TAR, etc.)
  • Cache/Build files
  • Media (Images, Video, Audio)
  • Documents (PDF, Office, Text)
  • Configuration files
• Flexible Display Options: Choose between a sorted mosaic view or a treemap-style visualization.

Installation

From PyPI

pip install disk-canvas

From Source

Clone the repository, then run:

cd disk-canvas
pip install .

Usage

Basic usage:

python -m disk_canvas /path/to/directory

Full options:

python -m disk_canvas /path/to/directory [-t TOP] [-f] [-d DEPTH] [-D] [-U]

Options:

• -t, --top: Number of largest items per depth (default: 10)
• -f, --files: Show only files (exclude directories)
• -d, --depth: Maximum directory depth (default: 1)
• -D, --detail: Display a detailed legend with file extensions
• -U, --unsort: Use unsorted (treemap) canvas layout (default is sorted mosaic)

Example Output

Color and Symbol Legend

The visualization uses different symbols for different file types:

• █ - Code files
• ▓ - Notebooks
• ▒ - Data files
• ◆ - Compressed files
• · - Cache files
• ◐ - Image files
• ◢ - Video files
• ◇ - Audio files
• ○ - Documents
• ☰ - Config files
• . - Other files

In simplified mode, similar categories share the same symbol for a cleaner view.

Requirements

• Python 3.8 or higher
• Linux or macOS (Windows support is limited due to terminal color support)
