Dhall is a programmable configuration language optimized for

maintainability.

You can think of Dhall as: JSON + functions + types + imports

Note that while Dhall is programmable, Dhall is not Turing-complete.  Many

of Dhall's features take advantage of this restriction to provide stronger

safety guarantees and more powerful tooling.

You can try the language live in your browser by visiting the official website:

# `dhall-python`

`dhall-python` contains [Dhall][dhall-lang] bindings for Python using the 

[rust][dhall-rust] implementation. It is meant to be used to integrate Dhall 

into your python applications.

If you only want to convert Dhall to/from JSON or YAML, you should use the

official tooling instead; instructions can be found

[here](https://docs.dhall-lang.org/tutorials/Getting-started_Generate-JSON-or-YAML.html).

## Usage

Install using pip:

```shell

pip install dhall

```

Supports the following:

- Operating Systems

  - Windows

  - Mac OS

  - Linux (manylinux_2_24_x86_64)

- Python versions

  - 3.7

  - 3.8

  - 3.9

  - 3.10

  - 3.11

Python 3.5 and 3.6 support is available in older versions of dhall-python.

dhall-python implements a similar API to Python's [json

module](https://docs.python.org/3/library/json.html):

```python

>>> import dhall

>>> dhall.dumps({"keyA": 81, "keyB": True, "keyC": "value"})

'{ keyA = 81, keyB = True, keyC = "value" }'

>>> dhall.loads("""{ keyA = 81, keyB = True, keyC = "value" }""")

{'keyA': 81, 'keyB': True, 'keyC': 'value'}

```

# Developer guide

This project uses [poetry](https://python-poetry.org/docs/) for managing the development environment. If you don't have it installed, run

```

curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python

export PATH="$HOME/.poetry/bin:$PATH"

```

The project requires the latest `stable` version of Rust.

Install it via `rustup`:

```

rustup install stable

```

If you have already installed the `stable` version, make sure it is up-to-date:

```

rustup update stable

```

After that, you can compile the current version of dhall-python and execute all tests and benchmarks with the following commands:

```

make install

make test

```

🤫 Pssst!... run `make help` to learn more.
