======= Plugins ======= Plugins (or entry points) enable the user to define custom classes and functions that can be used in ``nessai`` without having to edit the source code. For example, they can be used to support new proposal classes. ``nessai`` current supports the following entry points: * ``nessai.proposals``: this provides a means for adding additional proposal classes that can be used with the standard nested sampler instead of the default :code:`FlowProposal` class. Custom proposals ---------------- Custom proposals should inherit from :py:class:`nessai.proposal.flowproposal.FlowProposal` and made available using the ``nessai.proposals`` entry point. Once a custom proposal is installed, it can be used by specifying the :code:`flow_proposal_class` keyword argument when calling either :py:class:`~nessai.samplers.nestedsampler.NestedSampler` or :py:class:`~nessai.flowsampler.FlowSampler`. Known plugins ------------- * ``nessai-gw`` (`Homepage `_) - provides gravitational-wave specific proposals and reparameterisations.
