InputFileFormatter

This class produces produces a dump of the InputParameters that appears like the normal input file syntax.

This formatter is used for the --show-input command line option, described here. It is also available for the application developer, either directly or using an AdvancedOutput.

Example output

The snippet below shows the output for --show-input for the boundary condition and executioner blocks of the simple_diffusion test, shown further below. We can see additional metadata about each object, some default parameters that are not explicitly written in the input files, as well as disabled invalid parameters.
