# Dataclasses Avro Schema CLI
Command line interface from [dataclasses-avroschema](https://github.com/marcosschroh/dataclasses-avroschema) to work with `avsc` resources
[](https://github.com/marcosschroh/dc-avro/actions/workflows/tests.yaml)
[](https://github.com/marcosschroh/dc-avro/blob/master/LICENSE)
[](https://codecov.io/gh/marcosschroh/dc-avro)
## Requirements
`python 3.9+`
## Documentation
https://marcosschroh.github.io/dc-avro/
## Usage
You can validate one `avro schema` either from a `local file` or `url`:
Assuming that we have a local file `schema.avsc` that contains an `avro schema`, we can check whether it is valid
```bash
dc-avro validate-schema --path schema.avsc
Valid schema!! 👍
{
'type': 'record',
'name': 'UserAdvance',
'fields': [
{'name': 'name', 'type': 'string'},
{'name': 'age', 'type': 'long'},
{'name': 'pets', 'type': {'type': 'array', 'items': 'string', 'name': 'pet'}},
{'name': 'accounts', 'type': {'type': 'map', 'values': 'long', 'name': 'account'}},
{'name': 'favorite_colors', 'type': {'type': 'enum', 'name': 'FavoriteColor', 'symbols': ['BLUE', 'YELLOW', 'GREEN']}},
{'name': 'has_car', 'type': 'boolean', 'default': False},
{'name': 'country', 'type': 'string', 'default': 'Argentina'},
{'name': 'address', 'type': ['null', 'string'], 'default': None},
{'name': 'md5', 'type': {'type': 'fixed', 'name': 'md5', 'size': 16}}
]
}
```
You can validate several `.avsc` files with `lint` command
```bash
dc-avro lint tests/schemas/example.avsc tests/schemas/example_v2.avsc
👍 Total valid schemas: 2
tests/schemas/example.avsc
tests/schemas/example_v2.avsc
```
To see all the commands execute `dc-avro --help`
## Usage in pre-commit
Add the following lines to your `.pre-commit-config.yaml` file to enable avro schemas linting
```yaml
- repo: https://github.com/marcosschroh/dc-avro.git
rev: 0.7.0
hooks:
- id: lint-avsc
additional_dependencies: [typing_extensions]
```
