# ymlstash
A simple ORM-like utility for operating on local YAML files via Python dataclasses.
## Usage
Define a dataclass:
```python
from dataclasses import dataclass
from typing import ClassVar
@dataclass
class User:
name: str
age: int
active: bool
key: ClassVar[str] = "name"
```
Note the special `key` field which is used to denote that `name` should be used as the primary key field.
Instantiate a new object:
```python
user = User(name="yuval", age=42, active=True)
```
Save it to file:
```python
from ymlstash import YmlStash
stash = YmlStash(User, "path/to/db")
stash.save(user)
```
This will create a `yuval.yml` file in the stash root directory.
When saving to file, a `key` field must be present on the dataclass, otherwise an explicit `key` must be passed:
```python
stash.save(obj, key="custom-key")
```
Load from file:
```python
user = stash.load("yuval")
```
