autosar-data

library0.15.0pypypi✓ verified 83d ago

The `autosar-data` library provides tools to read, write, and modify AUTOSAR ARXML data using Python. It offers an object-oriented API for interacting with AUTOSAR workspaces, packages, and elements, simplifying development with ARXML files. The current version is 0.15.0, and it follows an infrequent but impactful release cadence, often introducing breaking changes related to API and Python version support between minor versions.

This quickstart demonstrates how to create an empty AUTOSAR workspace, add a package structure, create container and text elements, and then print the resulting ARXML content to a string. It also includes an example of how to load an ARXML file and access its content, highlighting the return value change for loading methods.

from autosar_data import Workspace from autosar_data.element import create_container import os # Create an empty workspace workspace = Workspace.create_empty() # Add a package structure packages = workspace.find_or_create_package('/MyProject/Packages') # Add a container element to the package container = create_container('ECU_CONFIGURATION', parent=packages) container.create_text_element('SHORT-NAME', 'MyEcuConfig') container.create_text_element('TYPE', 'ECU_EXTRACT') # Add a sub-element to the container sub_element = create_container('PARAMETERS', parent=container) sub_element.create_text_element('VALUE', '123') # Print the ARXML content to console arxml_string = workspace.to_string() print("Generated ARXML content:") print(arxml_string) # Example of loading from a file (requires a dummy file for execution) # Create a dummy ARXML file for demonstration dummy_arxml_path = 'dummy_example.arxml' with open(dummy_arxml_path, 'w') as f: f.write(arxml_string) try: # Load the workspace from the dummy file # Note: Workspace.from_file returns (workspace, errors) since v0.11.0 loaded_workspace, errors = Workspace.from_file(dummy_arxml_path) if errors: print(f"\nErrors found during loading: {errors}") else: print(f"\nSuccessfully loaded workspace from {dummy_arxml_path}.") # Access a value from the loaded workspace loaded_value_element = loaded_workspace.find('/MyProject/Packages/ECU_CONFIGURATION/PARAMETERS/VALUE') if loaded_value_element: print(f"Loaded value: {loaded_value_element.text_content}") except FileNotFoundError: print(f"Error: File not found at {dummy_arxml_path}") finally: # Clean up the dummy file if os.path.exists(dummy_arxml_path): os.remove(dummy_arxml_path)

Debug

Known issues

breakingStarting with version 0.15.0, `autosar-data` dropped support for Python 3.9 and 3.10. It now requires Python 3.11 or newer.

fix

Upgrade your Python environment to version 3.11 or higher. If you need to use Python 3.9/3.10, pin `autosar-data` to a version older than 0.15.0 (e.g., `pip install autosar-data<0.15`).

affects: >=0.15.0

breakingSince version 0.11.0, the methods `Workspace.from_file()` and `Workspace.from_string()` return a tuple `(workspace, errors)` instead of just the `workspace` object. Old code expecting only the workspace will raise a `TypeError`.

fix

Update your code to unpack the returned tuple: `workspace, errors = Workspace.from_file('file.arxml')`. Remember to check the `errors` list for parsing issues.

affects: >=0.11.0

breakingIn version 0.14.0, the method `AutosarData.parse_string()` was renamed to `AutosarData.from_string()`. Using the old name will result in an `AttributeError`.

fix

Replace `AutosarData.parse_string(...)` with `AutosarData.from_string(...)`. Note that `from_string` also returns a `(workspace, errors)` tuple.

affects: >=0.14.0

gotchaThe library can be strict with ARXML file structure and content according to the AUTOSAR standard. Malformed or non-compliant ARXML files may lead to parsing errors or unexpected behavior during loading.

fix

Always ensure your input ARXML files are well-formed XML and conform to the expected AUTOSAR schema. Use XML validation tools if encountering persistent parsing issues.

affects: all
