# API Reference

These pages are generated from the docstrings of each package. Each object is documented once, under the shortest path you can import it from (e.g. `pymmcore_plus.CMMCorePlus`, not `pymmcore_plus.core.CMMCorePlus`). Other modules that re-export it just link there.

- **[pymmcore-plus](<https://pymmcore-plus.github.io/pymmcore-plus/index.md>)**

  ---

  `CMMCorePlus` (all of the core's methods, marking what pymmcore-plus adds or changes), the acquisition engine, device objects, constants, metadata, and the [`mmcore` command line tool](<https://pymmcore-plus.github.io/pymmcore-plus/cli/index.md>).
- **[useq-schema](<https://pymmcore-plus.github.io/useq-schema/schema/sequence/index.md>)**

  ---

  `MDASequence`, `MDAEvent`, and the plans for each axis (time, z, positions, grids, autofocus).
- **[pymmcore-widgets](<https://pymmcore-plus.github.io/pymmcore-widgets/api/pymmcore_widgets/index.md>)**

  ---

  One page for each widget, with a screenshot and an example. (The [widget gallery](<https://pymmcore-plus.github.io/pymmcore-widgets/widgets/index.md>) is a quicker way to browse them.)
- **[pymmcore-gui](<https://pymmcore-plus.github.io/pymmcore-gui/api/pymmcore_gui/index.md>)**

  ---

  The application's entry points (`create_mmgui`) and the actions and widgets you can use to extend it.

napari-micromanager has no public Python API of its own, but you can drive it from a script (see [Scripting napari-micromanager](<https://pymmcore-plus.github.io/napari-micromanager/scripting/index.md>)).

Release notes for each package are on GitHub: [pymmcore-plus](<https://github.com/pymmcore-plus/pymmcore-plus/releases>), [useq-schema](<https://github.com/pymmcore-plus/useq-schema/releases>), [pymmcore-widgets](<https://github.com/pymmcore-plus/pymmcore-widgets/releases>), [napari-micromanager](<https://github.com/pymmcore-plus/napari-micromanager/releases>).

> Each package publishes an object inventory for [mkdocstrings](<https://mkdocstrings.github.io/>) and [intersphinx](<https://www.sphinx-doc.org/en/master/usage/extensions/intersphinx.html>), e.g. `https://pymmcore-plus.github.io/pymmcore-plus/objects.inv` (or `https://pymmcore-plus.github.io/objects.inv` for everything).
