Circular imports
----------------

Python is vulnerable to xsd circular imports. xsData by default groups all classes
by the schema location they are defined. This works well for schemas that avoid circular
imports. If you get import errors you should try one of the alternative structure
styles.

**clusters**

This style will identify the strongly connected classes and will group them together,
creating as many modules as possible. The modules are named after the the main class
of the group.

.. code-block:: console

    $ xsdata schema.xsd --package models --structure-style clusters


**namespaces**

This style will group classes by the target namespace they were originally defined. It
works well when the types of a namespace are spread across multiple schemas eg.
type substitutions, redefines.

.. code-block:: console

    $ xsdata schema.xsd --package models --structure-style namespaces


Since v21.8, the generator converts namespaces to packages similar to jaxb in order
to facilitate runs against multiple schemas from the same vendor.

.. list-table::
    :widths: 20 20
    :header-rows: 1

    * - Examples (before naming conventions)
      -
    * - http://www.w3.org/XML/1998/namespace
      - org.w3.xml.1998.namespace
    * - myNS.tempuri.org
      - org.tempuri.myNS
    * - urn:xmlns:25hoursaday-com:address
      - com.25hoursaday.address


**namespace-clusters**

This style combines the clusters and the namespace styles. It will fail if there
are strongly connected classes in the same graph from different namespaces.

.. code-block:: console

    $ xsdata schema.xsd --package models --structure-style namespace-clusters


**single-package**

This style will group all classes together into a single package eliminating imports
altogether.

.. code-block:: console

    $ xsdata schema.xsd --package models --structure-style single-package


Initialize Config

:ref:`more <Generator Config>`.

.. cli:: xsdata init-config --help

.. code-block:: console

    $ xsdata amadeus/schemas --config amadeus/.xsdata.xml
