""" | ||
Returns a list of action instances for a particular publish. | ||
This method is called each time a user clicks a publish somewhere in the UI. | ||
The data returned from this hook will be used to populate the actions menu for a publish. | ||
The mapping between Publish types and actions are kept in a different place | ||
(in the configuration) so at the point when this hook is called, the loader app | ||
has already established *which* actions are appropriate for this object. | ||
The hook should return at least one action for each item passed in via the | ||
actions parameter. | ||
This method needs to return detailed data for those actions, in the form of a list | ||
of dictionaries, each with name, params, caption and description keys. | ||
Because you are operating on a particular publish, you may tailor the output | ||
(caption, tooltip etc) to contain custom information suitable for this publish. | ||
The ui_area parameter is a string and indicates where the publish is to be shown. | ||
- If it will be shown in the main browsing area, "main" is passed. | ||
- If it will be shown in the details area, "details" is passed. | ||
- If it will be shown in the history area, "history" is passed. | ||
Please note that it is perfectly possible to create more than one action "instance" for | ||
an action! You can for example do scene introspection - if the action passed in | ||
is "character_attachment" you may for example scan the scene, figure out all the nodes | ||
where this object can be attached and return a list of action instances: | ||
"attach to left hand", "attach to right hand" etc. In this case, when more than | ||
one object is returned for an action, use the params key to pass additional | ||
data into the run_action hook. | ||
