mosaik.API-SemVer 2.4.2rc20210509000923

Python implementation of the mosaik API.

Mosaik API for Python

This is an implementation of the mosaik API for simulators written in Python. It hides all the messaging and networking related stuff and provides a simple base class that you can implement.

Status

Installation

Just use pip to install it:

$ pip install mosaik-api

Documentation

Please refer to mosaik’s documentation of the API.

Example Simulator

This distribution contains an example simulator in the example_sim package.

It can be started via the pyexamplesim command; pyexamplesim --help shows you how to use it.

It can also be run in-process by importing and calling example_sim.mosaik.main().

Example MAS

This distribution contains an example “multi-agent system” that uses the asyncronous remote calls to mosaik (get_progress(), get_related_entities(), get_data(), set_data()).

It can be started via the pyexamplemas command; pyexamplemas --help shows you how to use it.

It can also be run in-process by importing and calling example_mas.mosaik.main().

Development setup

To setup a devleopment environment, create a virtualenv and install the packages from requirements.txt:

$ mkvirtualenv --python=/usr/bin/python3 mosaik-api-python
(mosaik-api-python)$ pip install -r requirements.txt

To run the tests for the Python version you are currently using, execute pytest. You should also add the test coverage check:

(mosaik-api-python)$ pytest --cov=example_mas --cov=example_sim --cov=mosaik_api

To run the tests for all supported Python versions, run tox:

(mosaik-api-python)$ tox

Mosaik’s documentation contains more details.

Changelog

2.4.1 - 2019-05-15

• [NEW] Introduce semantic versioning.

2.4 - 2019-02-05

• [NEW] Simulator can now be started on a different node than mosaik, using the remote flag “-r” and the timeout flag “-t”. Mosaik can the integrate the simulator using the “connect” method of the simmanager.

2.3 – 2019-01-24

• [BugFix] Bugfix Tests

2.2 – 2016-02-15

• [NEW] API version 2.2: Added an optional “setup_done()” method.

• [CHANGE] API version validation: The API version is no longer an integer but a “major.minor” string. The major part has to math with mosaiks major version. The minor part may be lower or equal to mosaik’s minor version.

• [FIX] Various minor fixes and stability improvements.

2.1 – 2014-10-24

• [NEW] Allow extra API methods to be called. See http://mosaik.readthedocs.org/en/2.0/mosaik-api/high-level.html#mosaik_api.Simulator

• [CHANGE] The rel entry in the entity description returned by create() is now optional.

2.0 – 2014-09-22

• Initial release of the mosaik 2 Sim API for Python.
