sharables - "type" field (instance / function / schema / view)

[maxbates]

Add a field on set() to add a field primitive which differentiates between the four major data types

should also be in schema, e.g. function would encapsulate function, module, and subclasses of each

I have run into this before, and it looks like this will play into several of the features we’ve been talking about — it is sometimes difficult to determine the type of an object (at least on the client), because of all the subclasses etc.

It would be nice if there was an easier way to at least determine the type (Instance, Function, Sharable, View, etc.) of an object immediately, without having to do sequential get()s of the parent schemas.

E.g.

• in determining the editor to use
• in tokenization, to determine if a function was selected and the next autocompletion should be filtered based on argument type
• in conversion, limiting to certain schemas + subclasses, or minimally to instances
• in typeaheads, filtering to a type rather than specific schema

We shouldn't store that primitive variable in the database; we can add it programmatically during construction of the JSON.

moving this to higher priority - simplifies several features and its an easy fix
