Detailed Description

Dictionary entry that contains C++ OpenFOAM code that is compiled to generate the entry itself. So.

- codeStream reads three entries: 'code', 'codeInclude' (optional), 'codeOptions' (optional) and uses those to generate library sources inside codeStream/

E.g. to set the internal field of a field:

internalField  #codeStream
{
    code
    #{
        const IOdictionary& d = static_cast<const IOdictionary&>(dict);
        const fvMesh& mesh = refCast<const fvMesh>(d.db());
        scalarField fld(mesh.nCells(), 12.34);
        fld.writeEntry("", os);
    #};

    //! Optional:
    codeInclude
    #{
        #include "fvCFD.H"
    #};

    //! Optional:
    codeOptions
    #{
        -I$(LIB_SRC)/finiteVolume/lnInclude
    #};
};

Note the #{ ... #} syntax is a 'verbatim' input mode that allows inputting strings with embedded newlines.

Limitations:

Note
The code to be compiled is stored under the local codeStream directory with a subdirectory name corresponding to the SHA1 of the contents.

The corresponding library code is located under the local codeStream/platforms/$WM_OPTIONS/lib directory in a library libcodeStream_SHA1.so
