Set expression position

[Yuri Sulyma]

In the API, how do I insert a new expression between two existing expressions? setExpression() always appends to the list of expressions. I can work around this by using setState(), but that is very heavy-handed.

Thanks

Not sure if this is the right way to do it, but this code works fine.

Calc.controller.dispatch({
  type: "insert-item-at-index",
  state: {
    id: Calc.controller.generateId(),
    type: "expression",
    latex: "a=1"
  },
  index: 2
})

There is currently no supported way to set the expression order through the API. We caution people against manipulating states before passing them to `.setExpression()`, as they're intended to be opaque; and accessing the controller like this is also not supported. Your code should not rely on the controller name, or the specifics of what we dispatch (or the fact that we use a Flux architecture at all). Those are implementation details that are not part of the API contract and can change in breaking ways without notice.
