Alkali was featured on [PythonBytes](https://pythonbytes.fm/) episode

[#119](https://pythonbytes.fm/episodes/show/119/assorted-files-as-django-orm-backends-with-alkali)!

Alkali is a database engine, written in Python 3. It's raison d'être is

to provide a Django-like ORM while controlling the on disk format. If

you already have your data in a real database like Postgres then you'll

want SQLAlchemy, if however, your data is in json/yaml/csv/other/etc

files then Alkali might be exactly what you're looking for.

Full documentation at https://alkali.readthedocs.org

For some examples, please go straight to the quickstart guide:

https://alkali.readthedocs.io/en/master/quickstart.html

Here's a teaser to whet your appetite.

```python

import os

from alkali import Database, Model, fields, tznow

class Entry(Model):

   date    = fields.DateTimeField(primary_key = True)

   title   = fields.StringField()

   body    = fields.StringField()

   created = fields.DateTimeField(auto_now_add=True)

db = Database(models=[Entry], save_on_exit=True)

e = Entry(date=tznow(), title="my first entry", body="alkali is pretty good")

e.save()    # adds model instance to Entry.objects

title = Entry.objects.filter(date__le=tznow()).first().title

assert title == "my first entry"

db.store()

assert os.path.getsize('Entry.json')

```

## Installation

If you're reading this then you probably didn't install with `pip

install alkali` and get on with your life. You probably want to be able

edit the code and run tests and whatnot.

In that case run: `pip install -e .[dev]`

## Documentation

If you want to be able to build the docs then also run

```

pip install -e .[docs]

make html

```

## Testing

During development `pytest` was the runner of choice but any unit test

runner should work.

Examples:

* `pytest` run all tests

* `pytest -s` to see stdout (any print statements)

* `pytest --cov` to see test coverage

* `pytest -k test_1` to run all tests named *test_1*

* `pytest -k test_1 alkali/tests/test_fields.py` to run test_1 in test_fields.py
