Customisation

In case you want to extend/customize the FIDUCEO tools, your can provide your own code contribution and install it into the Python environment with the installed fiduceo package.

Here are the steps to your first plugin:

(1) Create a simple Python project my_project with the following structure:

my_project/
    setup.py
    my_package/
        __init__.py
        my_plugin.py

(2) In the module my_plugin.py define a function run() which could be implemented like so:

def run():
    # TODO: add useful example, e.g. register a new algorithm or replace an existing one
    pass 

(3) The package's __init__.py may be left empty.

(4) Write the setup.py script using the following template:

from distutils.core import setup

setup(name='my_package',
      version="1.0",
      description='My FIDUCEO tools contrib',
      author='Me',
      packages=['my_package'],
      install_requires=['fiduceo'],
      entry_points={
          'fiduceo_user_tools_plugins': [
              #
              # The following internal plugins are for unit-testing only:
              #
              # _test_plugin_1 does nothing
              'my_plugin = my_package.my_plugin:run_plugin',
          ],
      })  

(5) Cd into your project my_project and install your contribution module:

$ cd my_project
$ python3 setup.py develop

The next time you run any FIDUCEO tool, your plugins are executed as well.
