AttributeError("'module' object has no attribute 'Declare'",)

[jwmelto]

The first pass of parsing a file is reasonable, but leaves a lot of type deduction to the imagination. Now suppose that foo.m.py includes the following structure (where the types have been filled in):

structs = {
    "bar" : {
        "one"   : "int",
        "two"   : "mat",
     },
}

Running m2cpp with this file works just fine.

However, I know that another function is going to use the bar structure, and it accesses member "three". If I try to properly specify the structure as:

structs = {
    "bar" : {
        "one"   : "int",
        "two"   : "mat",
        "three" : "vec",
     },
}

then the next invocation of m2cpp will fail with AttributeError("'module' object has no attribute 'Declare'",). I also notice that there is a leftover .pyc file that isn't there when everything works.

See this isssue on StackOverflow for a hint on where the problem lies.
