storing array of dictionaries within t_dictionary

Zachary Seldess

Hi all,

Can anyone give me a few tips on saving dictionaries within an array inside a t_dictionary? Below is a code snippet where I embed several dictionaries inside a parent dictionary, naming their keys "0" through "n". What I really want to do is store these in an array within the top level dictionary (m_funcDict), whose name can be whatever.

best,
Zachary

void smap_trajectory_traj_to_dict(t_smap_trajectory *x)
{
    unsigned int i;
    
    dictionary_clear(x->m_funcDict);
    
    for (i = 0; i < x->m_funcSize; i++) {
        t_dictionary *funcDict = dictionary_new();
        char TrajNodeKey[15];
        sprintf(TrajNodeKey, "%d", i);
        
        dictionary_appendfloat(funcDict, gensym("x"), x->m_funcList[i].x);
        dictionary_appendfloat(funcDict, gensym("y"), x->m_funcList[i].y);
        dictionary_appendlong(funcDict, gensym("dur"), x->m_funcList[i].dur);
        dictionary_appenddictionary(x->m_funcDict, gensym(TrajNodeKey), (t_object *)funcDict);
    }
}

Hi there,

if I understand you correctly, this is what you want:

void smap_trajectory_traj_to_dict(t_smap_trajectory *x)
{
    t_atom argv[MAX_FUNC_SIZE];
    long argc = x->m_funcSize;
    long i;

    dictionary_clear(x->m_funcDict);

    for (i = 0; i < argc; i++) {

        t_dictionary *funcDict = dictionary_new();

        dictionary_appendfloat(funcDict, gensym("x"), x->m_funcList[i].x);
        dictionary_appendfloat(funcDict, gensym("y"), x->m_funcList[i].y);
        dictionary_appendlong(funcDict, gensym("dur"), x->m_funcList[i].dur);

        atom_setobj(argv+i, funcDict);
        // do not free funcDict because it is now owned by the atom array
    }
    dictionary_appendatoms(x->m_funcDict, gensym("funclist"), argc, argv);
}

I just coded it off the top of my head so it might need some retouching, but you get the idea.
Let me know if it serves your purpose...

Best

Thanks, Luigi. That was just the example I was looking for.
