loki.transformations.build_system.file_write

Transformations to be used in build-system level tasks

Classes

FileWriteTransformation([builddir, mode, ...])

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

Bases: Transformation

Write out modified source files to a select build directory

Parameters:

  • builddir (str or path) – Directory for the output to be written to

  • mode (str, optional) – “Mode” identifier string to add in front of the file suffix

  • 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.
