beancount-parser-lima may do a bit more than the existing core parser in Beancount proper. It processes all the included files and returns a date-ordered list of all the directives, with all pragmas either processed or returned as a single Options structure.
It doesn't do the filling in of missing numbers, because that seems tricky indeed (and an application level thing not a parser level thing). Nor plugins. I'm currently making good progress with Python bindings, including some performance optimisations to reduce the number of allocations of Python objects.
