I knew it was too easy. I'm still not clear on what you want, though.
Are modifying the VM, or writing a C library?

Hey Justin,
That's awesome and I thank you for your quick reply. However, what I
need is to be able to get the field names within the C binary, not the
neko code. Do you know how I might do that? What I was hoping for was
an undocumented method called something like "value*
val_object_fields( obj )" or somesuch (which I know doesn't exist
because I've trawled the C sources many times, but I live in hope).
Please don't think I'm ungrateful, though :-) I am, really.
Best,
Lee

Hey list,
I need to perform a conversion from a Neko object to a different vm
object instance, but to do so requires knowing what fields an object
contains. Is it possible to retrieve an array of field names that I
can iterate over to perform the conversion?
Thanks,
Lee
If the hashed names are alright, you can use $objfields(). Otherwise,
it just happens that I have such code sitting right here to return an
array of strings:
get_field_names = function(object) {
//$objfields returns an array of integers, which are the hashed
names of the fields
var field_list = $objfields(object)
//Number of fields in the array
var num_fields = $asize(field_list)
//Empty array to populate with field names
var field_names = $amake(num_fields)
//Index variable
var i = 0
//Loop over the fields
while(i < num_fields) {
//Convert integer field to string and store in array
field_names[i] = $field(field_list[i])
i = i + 1
}
return field_names
}
