🖼️ diagrams.sh

This script generates UML diagrams for a specified Python module using pyreverse. It checks for dependencies, loads environment variables, sets directories, and processes command-line arguments for customization of module names, directories, and output locations.

Overview

The script performs the following operations:

  • Dependency Checks: Verifies the presence of required tools:

    • graphviz for .dot file handling.
    • python for running Python-based commands.
    • pylint (with pyreverse) for generating UML diagrams.

  • Environment Variable Setup: Sets default values for module name, module directory, and output directory (MODULE_NAME, MODULE_DIR, OUTPUT_DIR). These can be customized via environment variables or command-line arguments.

  • Argument Parsing: Parses optional arguments to allow customization:

    • -m or --module-name to specify the module name.
    • -d or --module-dir to specify the module directory.
    • -o or --output-dir to specify the output directory.

  • Directory Creation: Creates subdirectories within the output directory for organizing different types of UML and flowchart outputs:

    • classes for class diagrams.
    • packages for package diagrams.

  • Diagram Generation: Runs pyreverse to create UML diagrams in multiple formats (html, pdf, png, and svg) and organizes them into respective directories.

  • Completion Message: Displays a message confirming successful generation of diagrams.

Usage

To run the script:

./diagrams.sh -m=<module_name> -d=<module_dir> -o=<output_dir>
