Transformations to be used in build-system level tasks

Classes

FileWriteTransformation([suffix, cuf, ...])

Write out modified source files to a select build directory
class FileWriteTransformation(suffix=None, cuf=False, style=None, include_module_var_imports=False)

Bases: Transformation

Write out modified source files to a select build directory

Parameters:

  • suffix (str, optional) – File suffix to determine file type for all written file. If omitted, it will preserve the original file type.

  • cuf (bool, optional) – Use CUF (CUDA Fortran) backend instead of Fortran backend.

  • include_module_var_imports (bool, optional) – Flag to force the Scheduler traversal graph to recognise module variable imports and write the modified module files.

traverse_file_graph = True
property item_filter

Override item_filter to configure whether module variable imports are honoured in the Scheduler traversal.

transform_file(sourcefile, **kwargs)

Defines the transformation to apply to Sourcefile items.

For transformations that modify Sourcefile objects, this method should be implemented. It gets called via the dispatch method apply().

Parameters:

  • sourcefile (Sourcefile) – The sourcefile to be transformed.

  • **kwargs (optional) – Keyword arguments for the transformation.

plan_file(sourcefile, **kwargs)

Define the planning steps to apply for Sourcefile items.

For transformations that modify the definitions or dependencies of sourcefile this should be implemented. It gets called via the dispatch method apply() if the optional plan_mode argument is set to True.

Parameters:

  • sourcefile (Sourcefile) – The sourcefile to be transformed.

  • **kwargs (optional) – Keyword arguments for the transformation.
