This is the fourth PR in a set of prs related to dbtypes.js. It does not work with the current dbtypes.js installed by cyclus in cyclus/cyclus#1184, but it does work with dbtypes.js.old that is also installed. It is depedent on cyclus/cyclus#1184.

Note that by "work" I mean: "builds and tests without error".

The (now with a better message) error that is raised on the current dbtypes.js is:

$ rm -r build; ./setup.py install --user && nosetests -w tests

Exception: KeyError with variable x of type (u'std::map', u'std::string') (in declaration): u'valdecl'

This failure goes away if the following types are removed:

    '["std::map< std::string, std::pair<double, std::map<int, double> > >", 3, "SQLite", "v1.3", 1],' +
    '["std::map< int, std::map< std::string, double> >", 3, "SQLite", "v1.3", 1],' +
    '["std::map< std::string, std::vector< std::pair< int, std::pair<std::string, std::string> > > >", 5, "SQLite", "v1.3", 1],' +
    '["std::map< std::string, std::pair<double, std::map<int, double> > >", 3, "HDF5", "v1.3", 0],' +
    '["std::map< int, std::map< std::string, double> >", 3, "HDF5", "v1.3", 0],' +
    '["std::map< std::string, std::vector< std::pair< int, std::pair<std::string, std::string> > > >", 5, "HDF5", "v1.3", 0],' +
    '["std::map< std::pair<int, std::string>, double >", 2, "HDF5", "v1.3", 0],' +

I can not find any simple unique features that explain the bug, so I will leave it to others to contemplate.

@gidden, after installing the changes from the relevant PR in cyclus, the following error happens whether genapi.py looks for dbtypes.js or dbtypes.js.old:

(gidden-updatets) $ ./setup.py install --user

I'm not exactly sure of whats happening in this function (outside of the obvious) so I don't have an explanation for this. Shouldn't this not happen with .old?

[opotowsky]

Or are the types you listed above still in .old? It's hard to tell without line numbers

FYI @rwcarlsen, @gonuke, this PR has a code snippet for generating enum types given a cpp type
