version (string or None) – version of the PFA language to use while interpreting (None defaults to titus.version.defaultPFAVersion)
sharedState (titus.genpy.SharedState) – external state for shared cells and pools to initialize from and modify; pass None to limit sharing to instances of a single PFA file
multiplicity (positive integer) – number of instances to return (default is 1; a single-item collection)
style (string) – style of scoring engine; only one currently supported: “pure” for pure-Python
debug (bool) – if True, print the Python code generated by this PFA document before evaluating
subs (dict from substitution names to substitutions) – replacement values as PFA titus.pfaast.Ast, PrettyPFA strings, or PFA Pythonized JSON
subs2 (dict from substitution names to substitutions) – added to subs (a more convenient way to pass them)
