| Parameters: | 
- text (string) – PrettyPFA to parse
 
- lineNumbers (bool) – if True include locator marks to trace back to PrettyPFA line numbers
 
- check (bool) – if True, check the result for PFA semantic errors (default True); Note: if the PrettyPFA contains any unresolved substitutions (in <<French quotes>>), it will not be checked
 
- version (string or None) – version of the PFA language to use while interpreting (None defaults to titus.version.defaultPFAVersion)
 
- 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)
