Project Hooks

Additionally, hooks can be defined for projects as arrays of arrays containing the action name and the arguments (if any). For example, one can define:

on_processing_ready: [
  ['run_cmd', 'date > {{project}}/ALL_DONE.txt'],
  ['run_cmd', 'sendmail ...']
]

or

on_add_dataset: [
  ['run_cmd', 'echo {{object}} > {{project}}/LATEST_DATASET.txt']
]

Supported events:

  • on_create(): When created

  • on_load(): When loaded

  • on_save(): When saved

  • on_add_dataset(object): When a dataset is added, with name object

  • on_unlink_dataset(object): When dataset with name object is unlinked

  • on_result_ready(object): When any result is ready, with key object

  • on_result_ready_{result}(): When result is ready

  • on_processing_ready(): When processing is complete

Supported hooks:

  • run_lambda(lambda, args...)

  • run_cmd(cmd)
