# py-d2

![Banner](docs/images/banner.png)

An unofficial, fully typed python interface for building [.d2](https://github.com/terrastruct/d2) diagram files in python.

## Installation

```bash
pip install py-d2
```

## Usage

```python
from py_d2 import D2Diagram, D2Shape, D2Connection, D2Style

shapes = [
    D2Shape(name="shape_name1", style=D2Style(fill="red")),
    D2Shape(name="shape_name2", style=D2Style(fill="blue"))]
connections = [
    D2Connection(shape_1="shape_name1", shape_2="shape_name2")
]

diagram = D2Diagram(shapes=shapes, connections=connections)

with open("graph.d2", "w", encoding="utf-8") as f:
    f.write(str(diagram))

```

produces the following graph.d2 file:

```d2

shape_name1: {
  style: {
    fill: red
  }
}
shape_name2: {
  style: {
    fill: blue
  }
}
shape_name1 -> shape_name2

```

This can be rendered using `d2 graph.d2 graph.svg && open graph.svg` or [https://play.d2lang.com/](https://play.d2lang.com/) to produce

## Development
### Prerequisite

- [Python 3.7+](https://www.python.org/)
- [Poetry 1.3](https://python-poetry.org/)
- [pre-commit](https://pre-commit.com/)

### Installation

following the steps below to setup the project:

```bash

```bash
# Clone the repository
git clone git@github.com:MrBlenny/py-d2.git && cd py-d2

# Install all dependencies
poetry install --sync --all-extras --with dev,test,coverage

# install git hook scripts for development
pre-commit install

# Install dependencies with group 'dev'、'test' for development
poetry install --with dev,test
# Only install required dependencies for production
poetry install
```

### Usage

There are some useful commands for development:

```bash
# Run the example
poetry run example

# Debug with ipdb3
poetry run ipdb3 ./src/py_d2/main.py

# Code test
poetry run pytest -s

# Run default coverage test
poetry run tox

# Run example project coverage test at python 3.9 and 3.10
poetry run tox -e py{39,310}-py-d2

# Lint with black
poetry run black ./src --check

# Format code with black
poetry run black ./src

# Check with mypy
poetry run mypy ./src

# Check import order with isort
poetry run isort ./src --check

# Lint with flake8
poetry run flake8 ./src
```
