## Installation
```
pip install adis
```

## Examples
### Parse an ADIS file and turn it to JSON
```python
# example_adis_to_json.py
from adis import Adis

adis = Adis.parse_from_file("sample.ads")
generated_json = adis.to_json()

print(generated_json)
```
Prettyprinted output:
```json

### Turn a JSON file to ADIS
```python
# example_json_to_adis.py
from adis import Adis

adis = Adis.from_json_file("sample.json")
generated_adis_text = adis.dumps()

print(generated_adis_text)
```
Output:
```

## About the ADIS format
Each physical file can contain multiple logical ADIS files, these are represented by objects of the type `AdisFile`.
Each of those logical ADIS files contains one or multiple blocks, these are represented by objects of the type `AdisBlock`.
Each block consists of the definitions for the fields (list of objects of type `AdisFieldDefinition`) and one or multiple
data rows (list of list of `AdisValue`).

## Documentation
This documentation only contains methods that are inteded to be used by the user.
Take a look at the docstrings for more information about methods.

### Adis
Static methods:
* `parse(text)`: Creates an `Adis` object from a text that's in the ADIS format
* `parse_from_file(path_to_file)`: Creates an `Adis` object from an ADIS file
* `from_json(json_text)`: Create an `Adis` object from a json text
* `from_json_file(path_to_json_file)`: Create an `Adis` object from a json file

Normal methods:
* `__init__(blocks)`: Creates an `Adis` object from a list of `AdisFile`s
* `to_json()`: Creates a json text containing the files, definitions and data
* `dumps()`: Creates a text in the ADIS format
* `get_files()`: Returns a list of `AdisFile`s

### AdisFile
Normal methods:
* `__init__(blocks)`: Creates an `AdisFile` from a list of `AdisBlock`s
* `get_blocks()`: Returns a list of `AdisBlock`s

### AdisBlock
Normal methods:
* `__init__(entity_number, status, field_definitions, data_rows)`: Creates an `AdisBlock`
* `get_entity_number()`: Returns the entity number of this `AdisBlock`
* `get_field_definitions()`: Returns the field definitions as list of `AdisFieldDefinition`s
* `get_data_rows()`: Returns the data rows as list. Each data row is a list of `AdisValue`s

### AdisFieldDefinition
Normal methods:
* `__init__(item_number, field_size, decimal_digits)`: Creates an `AdisFieldDefinition`
* `get_item_number()`: Returns the item number
* `get_field_size()`: Returns the field size
* `get_decimal_digits()`: Returns the number of decimal digits

### AdisValue
Normal methods:
* `__init__(item_number, value)`: Creates an `AdisValue`
* `to_dict()`: Returns a dict containing the item number and value of this `AdisValue`
