YAML

This expdef plugin can be selected via --expdef=expdef.yaml. This plugin supports flattening/nested configuration files.

Important

If multiple matches for a given YAMLpath string are found, ALL are modified accordingly when updating attributes.

Requirements

• __CONTROLLER__ - Tag used when as a placeholder for selecting which controller present in an input file (if there are multiple) a user wants to use for a specific Experiment. Can appear in YAML attributes. This makes auto-population of the controller name based on the --controller argument and the contents of controllers.yaml (see Project YAML Configuration for details) in template input files possible.

Furthermore, while YAML treats keys mapping to subtrees and keys mapping to literal attributes equivalently, SIERRA does not, in order to provide uniformity across the different input file types it can handle. Functionally this means that if you ask SIERRA to update an attribute for a literal/scalar, and that "attribute" actually maps to a sub-tree, you will get an error, even though making a change of that nature is a perfectly valid YAML modification.

Added in version 1.5.2.
