Detailed Description

Compilers are simple functions.

def translate(graph: Graph, identifier: str, peano_project: "peano4.api.Project") -> List["peano4.api.solversteps.Step"]:

which take a task graph and yield a series of peano4.api.solversteps.Step instances. The peano_project is the Peano project the steps eventually are added to. Compilers can use it to add further data to the data model (peano4.api.taskgraph.compiler.CellTaskProducerConsumer). It might be None if a compiler is used outside of a project, e.g. in unit tests.

In the Peano terminology, a

peano4.api.solversteps.Step corresponds to an Observer: for every mesh traversal, the traversal automaton is handed an observer that distributes the grid events among the action sets tied to it.

There is one notable exception compared to the plain steps in peano4.api.solversteps: Each step is also added an attribute has_to_repeat which is a copy from Task's has_to_repeat. Consult the description of peano4.api.taskgraph.Task for details on how to use this attribute to make a task repeat until a certain condition is met.
