@active_if(CONDITIONAL) #36

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
A way of switching off a task if CONDITIONAL is false.
The task function would still be in the dependency tree but would create no 
jobs.

Implemented for v 23

* Design and initial implementation from Jacob Biesinger
* Takes one or more parameters which can be either booleans or functions / 
  callable objects which return True / False
* The expressions inside @active_if are evaluated each time 
  `pipeline_run`, `pipeline_printout` or `pipeline_printout_graph` is called.
* Dormant tasks behave as if they are up to date and have no output.
