objects.

API docs
Queenbee-DSL API docs
Requirements
Python >=3.7
Installation

Clone this repository.

pip install .

Quick Start
If you are interested to start writing your own plugins and recipe see the
introduction post.
Function
from dataclasses import dataclass
from queenbee_dsl.function import Function, command, Inputs, Outputs

@dataclass
class CreateOctreeWithSky(Function):
"""Generate an octree from a Radiance folder and sky!"""

# inputs
include_aperture = Inputs.str(
default='include',
description='A value to indicate if the static aperture should be included in '
'octree. Valid values are include and exclude. Default is include.',
spec={'type': 'string', 'enum': ['include', 'exclude']}
)

black_out = Inputs.str(
default='default',
description='A value to indicate if the black material should be used. Valid '
'values are default and black. Default value is default.',
spec={'type': 'string', 'enum': ['black', 'default']}
)

model = Inputs.folder(description='Path to Radiance model folder.', path='model')

sky = Inputs.file(description='Path to sky file.', path='sky.sky')

@command
def create_octree(self):
return 'honeybee-radiance octree from-folder model --output scene.oct ' \
'--{{self.include_aperture}}-aperture --{{self.black_out}} ' \
'--add-before sky.sky'

# outputs
scene_file = Outputs.file(description='Output octree file.', path='scene.oct')

The Queenbee class is accessible from queenbee property.
Try print(CreateOctreeWithSky().queenbee.yaml()) and you should see the full Queenbee
definition:
type: Function
annotations: {}
inputs:
- type: FunctionStringInput
annotations: {}
name: black-out
description: A value to indicate if the black material should be used. Valid values
are default and black. Default value is default.
default: default
alias: []
required: false
spec:
type: string
enum:
- black
- default
- type: FunctionStringInput

description: Output octree file.
path: scene.oct

description: Generate an octree from a Radiance folder and sky!
command: honeybee-radiance octree from-folder model --output scene.oct --{{inputs.include-aperture}}-aperture
--{{inputs.black-out}} --add-before sky.sky

Since the functions are standard Python classes you can also subclass them from one
another.
Plugin
To create a Queenbee plugin use the functions to create a standard Python module. The only
change is that you need to provide the information for Queenbee plugin in the __init__.py
file as dictionary assigned to __queenbee__ variable.
In the near future we might be able to use Python package's information to collect most
of these information.
Follow the standard way to install a Python package. Once the package is installed you
can use queenbee-dsl to load the package or write it to a folder.
from queenbee_dsl.package import load, write

# name of the queenbee package
python_package = 'pollination_honeybee_radiance'

# load this package as Queenbee Plugin
plugin = load(python_package)

# or write the package as a Queenbee plugin to a folder directly
write(python_package, './pollination-honeybee-radiance')

See pollination-honeybee-radiance plugin for a full project example.
Recipe
Recipe is a collection of DAGs. Each DAG is a collection of interrelated tasks.
You can use queenbee-dsl to create complex recipes with minimum code by reusing the functions
as templates for each task.
Packaging a plugin is exactly the same as packaging a plugin.
from queenbee_dsl.package import load, translate

# name of the queenbee package
python_package = 'daylight-factor'

# load this package as Queenbee Recipe
recipe = load(python_package, baked=True)

# or translate and write the package as a Queenbee plugin to a folder directly
translate(python_package, './daylight-factor')

See daylight factor recipe for a full project example.
How to create a queenbee-dsl package
Queenbee-dsl uses Python's standard packaging to package queenbee plugins and recipes.
It parses most of the data from inputs in setup.py file and some Queenbee specific
information from __init__.py file. Below is an example of how these file should look
like.
setup.py
#!/usr/bin/env python
import setuptools

# These two class extends setup.py to install the packages as queenbee packages
from queenbee_dsl.package import PackageQBInstall, PackageQBDevelop

# Read me will be mapped to readme strings
with open("README.md", "r") as fh:
long_description = fh.read()

setuptools.setup(
cmdclass={'develop': PackageQBDevelop, 'install': PackageQBInstall}, # required - include this for queenbee packaging
name='pollination-honeybee-radiance', # required - will be used for package name unless it is overwritten using __queenbee__ key in __init__.py
version='0.1.0', # required - will be used as package tag. you can also use semantic versioning
url='https://github.com/pollination/pollination-honeybee-radiance', # optional - will be translated to home
description='Honeybee Radiance plugin for Pollination.', # optional - will be used as package description
long_description=long_description, # optional - will be translated to ReadMe content on Pollination
long_description_content_type="text/markdown",
author='author_1', # optional - all the information for author and maintainers will be
author_email='author_1@example.com', # translated to maintainers. For multiple authors use comma
maintainer='maintainer_1, maintainer_2', # inside the string.
maintainer_email='maintainer_1@example.come, maintainer_2@example.com',
packages=setuptools.find_packages('pollination_honeybee_radiance'), # required - standard python packaging input. not used by queenbee
keywords='honeybee, radiance, ladybug-tools, daylight', # optional - will be used as keywords
license='PolyForm Shield License 1.0.0, https://polyformproject.org/wp-content/uploads/2020/06/PolyForm-Shield-1.0.0.txt' # optional - the license link should be separated by a comma
)

init.py
Here is an example __init__.py for a plugin.
__queenbee__ = {
'name': 'honeybee-radiance', # optional - new name for queenbee package. this will overwrite the Python package name
'icon': 'https://ladybug.tools/assets/icon.png', # optional - package icon
'config': { # required for Pollination - docker information for this specific plugin
'docker': {
'image': 'ladybugtools/honeybee-radiance:1.28.12',
'workdir': '/home/ladybugbot/run'
}
}
}

Here is an example __init__.py for a recipe.
from .entry import AnnualDaylightEntryPoint

__queenbee__ = {
'name': 'annual-daylight', # optional - new name for queenbee package. this will overwrite the Python package name
'icon': 'https://ladybug.tools/assets/icon.png', # optional - package icon
'entry_point': AnnualDaylightEntryPoint, # required - this will point queenbee to the class that should be used to start the run
