Installation of Dahu
====================

Dahu is a Python project, the only dependency is `numpy` but `Tango` is needed for the server part.

.. code-block:: shell

    cd dahu
    python run_tests.py
    pip wheel .
    pip install  dahu-*.whl


Dahu can also be installed as debian package with automatic packaging from the `build-deb.sh` tool.
Documentation can be generated with `python build_doc.py`.


Development of Dahu
===================

`Dahu` is an Open source project under MIT license available at:
https://github.com/kif/dahu

There is a minimal test-suite which ensures the dynamic loading works as expected.
The kernel of `dahu` is tested, but plugins are not.


Development of plugins
======================

Plugins are regrouped into the `plugin` directory.
There is one directory per beamline and several plugins per beamline.
Each beamline is independent so no interference are expected.

Dahu can be tested on plugins in an alternative directory using the `$DAHU_PLUGINS` environment variable.

Different examples of plugins are provided in the plugins/example.py file, either based on a function or a class with the `@register` decorator.
