Author and visualize multiverse analysis with ease.

Boba has a domain specific language (Boba DSL) for writing multiverse specifications,
and a visual analysis interface (`Boba Visualizer`_) for exploring multiverse outcomes.
Boba comes with a command line tool to parse your DSL specification and generate
universe scripts, execute all scripts with a single command,
merges outputs into a table, and invoke the visualizer.

- works with both python and R, and other scripting languages to come
- handles simple parameter substitution as well as complex code flow dependency
- offers interactive visualizations for exploring consequential decisions, uncertainty, model fit, and more

Installation
============

You might download and install the latest version of this software from the
Python package index (PyPI)::

  pip install --upgrade boba

Usage
=====

To author your multiverse, please refer to the specification rules_.
Here is a `simple example`_ to get you started!


To parse your specification and generate actual scripts, invoke boba and pass
in the path to your template script and your JSON spec::

  boba compile --script template.py

To execute the multiverse, namely running all the generated scripts, use::

  boba run --all

To start the Boba Visualizer after getting the intermediate output files, use::

  boba-server

For more command line options, see `CLI`_.
For more information about the Boba Visualizer, see this project_.

Examples

- A `simple example`_ to walk you through the basics
- A `more complex example`_ using `Steegen's multiverse analysis`_ and `Durante's fertility dataset`_.
- Another multiverse example_, based on the `specification curve paper`_ by Simonsohn et al.
