Custom mimetypes

[rgbkrk]

I'm relying on IRdisplay::publish_mimebundle to send over a custom mime bundle right now. Is this the interface I should come to rely on?

mimebundle <- list('application/json+myspecialtype' = myStructure)
IRdisplay::publish_mimebundle(mimebundle)

It's working well, I just want to make sure it's in line with your direction here and in IRdisplay.

yes, it is. if there’s a general use case for that mimetype, we can add a function to create it from objects (repr_<name>), but if it’s only of limited use or completely application specific, what you do is the best way.

to expand on it: IRdisplay has a bunch of format-specific shortcut functions and two fundamental functions:

• prepare_mimebundle, and
• publish_mimebundle

the pages explain what the functions do. display basically chains the other two.

Cool, that's great then. One is fairly specific and will only be implemented in one library (most likely) and more than one frontend. Example for Plotly.js: nteract/nteract#662

Vega, vegalite, and victory are in the works.
