Setup Micro-Manager Test Device Adapters

A GitHub Action that downloads and installs platform-specific Micro-Manager test device adapters from the mm-test-adapters repository.

Usage

- name: Install MM test adapters
  uses: pymmcore-plus/setup-mm-test-adapters@main
  with:
    # all inputs are optional
    version: latest  # or a specific version, e.g. 74, or 74.20250829
    destination: ./mm-test-adapters

Inputs

Name	Description	Required	Default
version	Version to install	No	latest
destination	Directory where test adapters will be installed	No	See below

If destination is not not provided, adapters will be installed into a Micro-Manager-YYYYMMDD folder inside the default pymmcore-plus install location

• Windows: $LOCALAPPDATA/pymmcore-plus/pymmcore-plus/mm
• macOS: $HOME/Library/Application Support/pymmcore-plus/mm
• Linux: $HOME/.local/share/pymmcore-plus/mm

Tip

These are the directories that mmcore install installs to, and where pymmcore_plus.find_micro_manager() will look for Micro-Manager installations at runtime.

Outputs

Name	Description
version	Resolved adapter version (DIV or DIV.YYYYMMDD)
destination	Final directory into which the adapters were extracted
