Breaking changes and how to\nmigrate to the new version will be documented in the\n[changelog](https://github.com/c4deszes/ldfparser/blob/master/CHANGELOG.md) and on the\n[Github releases page](https://github.com/c4deszes/ldfparser/releases).\n\nThe tool has been written according the LIN standards [1.3](docs/external/LIN_1.3.pdf),\n[2.0](docs/external/LIN_2.0.pdf), [2.1](docs/external/LIN_2.1.pdf) and [2.2A](docs/external/LIN_2.2A.pdf),\nbut due to errors in the documentation there's no guarantee that the library will be able to parse your LDF.\nIn such cases if possible first verify the LDF with a commercial tool such as Vector LDF Explorer or the\ntool that was used to create the LDF.  If the LDF seems to be correct then open a new issue.\nI also recommend trying the LDF to JSON conversion mechanism, see if that succeeds.\n\nThe LIN standard is now known as [ISO 17987](https://www.iso.org/standard/61222.html) which\nclears up some of the confusing parts in the 2.2A specification. Since this new standard is not\nfreely available **this library won't support the modifications present in ISO 17987**. I don't\nthink it's going to a huge problem because the LIN 2.2A released in 2010 has overall better adoption.\n\nThe LDF usually contains sensitive information, if you need to open an issue related to the parser\nthen try to provide either an anonymized version with signals and frames obfuscated or just the\nrelevant segments in an example LDF when opening issues.\n\n---\n\n## Installation\n\nYou can install this library from PyPI using pip.\n\n```bash\npip install ldfparser\n```\n\n---\n\n## Examples\n\n```python\nimport ldfparser\nimport binascii\n\n# Load LDF\nldf = ldfparser.parse_ldf(path = \"network.ldf\")\nframe = ldf.get_unconditional_frame('Frame_1')\n\n# Get baudrate from LDF\nprint(ldf.get_baudrate())\n\n# Encode signal values into frame\nmessage = frame.encode_raw({\"Signal_1\": 123, \"Signal_2\": 0})\nprint(binascii.hexlify(message))\n\u003e\u003e\u003e 0x7B00\n\n# Decode message into dictionary of signal names and values\nreceived = bytearray([0x7B, 0x00])\nprint(frame.decode(received))\n\u003e\u003e\u003e {\"Signal_1\": 123, \"Signal_2\": 0}\n\n# Encode signal values through converters\nmessage = frame.encode({\"MotorRPM\": 100, \"FanState\": \"ON\"})\nprint(binascii.hexlify(message))\n\u003e\u003e\u003e 0xFE01\n```\n\nMore examples can be found in the [examples directory](./examples).\n\n---\n\n## Documentation\n\nDocumentation is published to [Github Pages](https://c4deszes.github.io/ldfparser/).\n\n---\n\n## Features\n\n+ Semantic validation of LDF files\n\n+ Retrieve header information (version, baudrate)\n\n+ Retrieve Signal and Frame information\n\n+ Retrieve Signal encoding types and use them to convert values\n\n+ Retrieve Node attributes\n\n+ Retrieve schedule table information\n\n+ Command Line Interface\n\n+ Capturing comments\n\n+ Encode and decode standard diagnostic frames\n\n+ Saving LDF object as an `.ldf` file (experimental)\n\n### Known issues / missing features\n\n+ Certain parsing related errors are unintuitive\n\n+ Checksum calculation for frames\n\n+ Token information is not preserved\n\n---\n\n## Development\n\nInstall the library locally by running `pip install -e .[dev]`\n\n[Pytest](https://pytest.org/) is used for testing, to execute all tests run `pytest -m 'not snapshot'`\n\n[Flake8](https://flake8.pycqa.org/en/latest/) is used for linting, run `flake8` to print out all linting errors.\n\n---\n\n## Contributors\n\n[@c4deszes](https://github.com/c4deszes) (Author)\n\n---\n\n## Credits\n\nInspired by [uCAN-LIN LinUSBConverter](https://github.com/uCAN-LIN/LinUSBConverter), specifically the LDF parsing mechanism via [Lark](https://github.com/lark-parser/lark). Previously the library included most of the lark file, parsing code and examples, since 0.5.0 they've been completely rewritten to better accomodate the different LIN standards.\n\n---\n\n## License\n\n[![License: MIT](https://img.shields.io/badge/License-MIT-blue.svg)](https://opensource.org/licenses/MIT)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fc4deszes%2Fldfparser","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fc4deszes%2Fldfparser","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fc4deszes%2Fldfparser/lists"}
