Assorted fixes from trawling the sphinx logs - malformed formatting, broken references, leftovers from renaming action-task to action-callback and removing yaml-templates, docstring fixes to make sphinx happier, and typos.

Loading Tasks
|
|
=============
|
|
|
|
The full task graph generation involves creating tasks for each kind. Kinds
|
|
are ordered to satisfy ``kind-dependencies``, and then the ``loader`` specified
|
|
in ``kind.yml`` is used to load the tasks for that kind. It should point to
|
|
a Python function like::
|
|
|
|
def loader(cls, kind, path, config, parameters, loaded_tasks):
|
|
pass
|
|
|
|
The ``kind`` is the name of the kind; the configuration for that kind
|
|
named this class.
|
|
|
|
The ``path`` is the path to the configuration directory for the kind. This
|
|
can be used to load extra data, templates, etc.
|
|
|
|
The ``parameters`` give details on which to base the task generation. See
|
|
:doc:`parameters` for details.
|
|
|
|
At the time this method is called, all kinds on which this kind depends
|
|
(that is, specified in the ``kind-dependencies`` key in ``config``)
|
|
have already loaded their tasks, and those tasks are available in
|
|
the list ``loaded_tasks``.
|
|
|
|
The return value is a list of inputs to the transforms listed in the kind's
|
|
``transforms`` property. The specific format for the input depends on the first
|
|
transform - whatever it expects. The final transform should be
|
|
``taskgraph.transform.task:transforms``, which produces the output format the
|
|
task-graph generation infrastructure expects.
|
|
|
|
The ``transforms`` key in ``kind.yml`` is further documented in
|
|
:doc:`transforms`. For more information on how all of this works, consult the
|
|
docstrings and comments in the source code itself.
