How can I write the dictionary without key in snappyHexMeshDict？

[zzkluck]

I am trying to generate a snappyHexMeshDict and encountering such an example. The whole snappyHexMeshDict I want is like:

.....
castellatedMeshControls
{
    ......
    features
    (
        {
            file        "cylinder.eMesh";
            levels       ((0.5 4));
        }
    );
    ......
}
......

That's a list of dictionary without keys. It seems that openfoam uses a very different syntax here than it does elsewhere. My intuition is that will work:

snappy_dict["castellatedMeshControls"] = {
    ......
    "features": [{
        "file": "cylinder.eMesh",
        "levels":  "((0.5 4))";
    }],
    ......
}

But this will output:

features 
(
    file "cylinder.eMesh"; 
    levels ((0.5 4));
);

I tried several other methods, but found it difficult. What I can do here?

@zzkluck Thanks for the report. I hadn't considered this case, so indeed I don't think there's a way to read/write something like this now. I'll try to get a fix out as soon as possible.

@zzkluck Thanks again. Version 0.8.0 is now out and should fix this. Feel free to reopen otherwise.

Actually, 0.8.0 is not yet published on PyPI because the release workflow bumps into a setuptools bug (pypa/setuptools#4759). Sorry about that. I'll keep trying to publish it

0.8.0 is now out

Thank you for such a quick update, now my code can work well!
