taskgraph.loader package¶
taskgraph.loader.transform module¶
- taskgraph.loader.transform.loader(kind, path, config, params, loaded_tasks)¶
Get the input elements that will be transformed into tasks in a generic way. The elements themselves are free-form, and become the input to the first transform.
By default, this reads jobs from the jobs key, or from yaml files named by jobs-from. The entities are read from mappings, and the keys to those mappings are added in the name key of each entity.
If there is a job-defaults config, then every job is merged with it. This provides a simple way to set default values for all jobs of a kind. The job-defaults key can also be specified in a yaml file pointed to by jobs-from. In this case it will only apply to tasks defined in the same file.
Other kind implementations can use a different loader function to produce inputs and hand them to transform_inputs.
