Ontol DSL Parser

Authors: Skvortsov Vladimir, Aptukov Mikhail, Markov Mikhail, Khamidullin Ilsaf, Afanasyev Andrew.

Ontol DSL Parser is a command-line tool for parsing and visualizing ontology files written in the Ontol DSL. It generates JSON representations and PlantUML diagrams from .ontol files.

Features

• Parse .ontol files to extract ontology structures.
• Serialize ontology to JSON format.
• Generate PlantUML diagrams from ontology.
• Automatically render PlantUML diagrams to PNG images.
• Watch files for changes and re-parse them automatically.
• Display version and help information.

Requirements

• Python 3.9 or higher
• Java (for local PlantUML rendering)
• PlantUML (for local rendering)

Installation

Install from PyPi:

pip install ontol

Usage

Parse a file

To parse an .ontol file and generate JSON and PlantUML files:

ontol path/to/yourfile.ontol

Watch Mode

To watch a file for changes and automatically re-parse it:

ontol path/to/yourfile.ontol --watch

Debug mode

To enable debug mode, which retranslates the output back to the .ontol file:

ontol path/to/yourfile.ontol --debug

Display Version

To display the version of the program:

ontol --version

Help

To display help information:

ontol --help

Tests

To display run tests:

pytest tests

Output

• JSON File: A JSON representation of the ontology is saved with the same basename as the .ontol file.
• PlantUML File: A .puml file is generated for visualization.
• PNG Image: A PNG image is rendered from the PlantUML file.

Debug mode

When the --debug flag is used, the parser retranslates the output back to the .ontol file. This is particularly useful for debugging, as it allows you to verify the accuracy and consistency of the parsing process. The retranslated file is saved with the same name as the original .ontol file, enabling easy comparison between the original and retranslated versions.
