# pydbc

## Status

![Test Python package](https://github.com/Sauci/pydbc/workflows/Test%20Python%20package/badge.svg)

## Package description

The purpose of this package is to generate an AST based on the content of DBC-formatted string. Bellow a short example:

```python

from pydbc.parser import DbcParser

dbc_data = """

VERSION "my_version"

NS_ :

  BU_EV_REL_

  BU_BO_REL_

BO_ 1234 my_message_name: 2 my_transmitter

  SG_ my_first_signal_name : 56|8@1+ (16,0) [0|4000] "my_first_signal_unit" my_first_signal_transmitter

  SG_ my_second_signal_name : 48|8@1+ (1,0) [0|250] "my_second_signal_unit" my_first_signal_transmitter

"""

if __name__ == '__main__':

    p = DbcParser(dbc_data)

    assert p.ast.version == 'my_version'

    assert p.ast.messages[0].identifier == 1234

    first_signal = p.ast.messages[0].signals[0]

    assert first_signal.name == 'my_first_signal_name'

    assert first_signal.signal_size == 8

    assert first_signal.start_bit == 56

    assert first_signal.value_type == '+'

    assert first_signal.factor == 16

    assert first_signal.offset == 0

    assert first_signal.minimum == 0

    assert first_signal.maximum == 4000

```
