restore "promise-calling" to be a linkable defined term?

[equalsJeffH]

It'd be helpful if "promise-calling" would be made (restored as?) a <dfn> so other specs can auto-link to it, e.g., as https://www.w3.org/TR/credential-management-1/ does (the link now does not resolve correctly (it used to IIRC)). thx.

@equalsJeffH, the promises guide merged into the WebIDL spec. Not sure if what you need is there (doesn't seem "promise calling" is there)... but likely what you want is already exported.

@equalsJeffH see links from #27. This is intentional and you'll need to refactor. Unfortunately we don't have tooling yet whereby we can find all downstream dependencies and notify them of a change.

Indeed. Promise calling is no longer needed; as long as you use Web IDL promise-returning callback types, you get that automatically by using the usual "invoke" hook.

Or in other words, per https://www.w3.org/2001/tag/doc/promises-guide#should-promise-call ,

In Web IDL-using specifications, this is automatically taken care of if you declare the developer function as a callback function and then invoke it.

Hope this helps. I'll close the issue since we won't be adding a separate promise-calling operation back, but feel free to ask here or elsewhere if you need help with using Web IDL callback functions.

Thx @domenic -- I do have a question: what we are presently "promise-calling" in the credential-management (credman) spec is an algorithm returned by webauthn.

You can find this returned webauthn alg by searching the webauthn editors' draft spec for "Let constructCredentialAlg be". Where it is invoked from credman can be found by searching the credman editors' draft for "promise-calling".

Ought we formally declare that alg in webauthn as (this flavor of) a callback function? And then I'm wondering whether it will more or less work automagically if we invoke it from credman. Tho, the invoke alg assumes the callback function is written in script? Is what we're trying to do here similar to what "Issue 6" in WebIDL S 2.10. Callback functions is talking about where it says:

...use callback function types for platform object provided functions...

...?

[domenic]

Ah, hmm, that's a bit strange. Promise-calling only ever worked on JS functions.

Since I assume the algorithms in question are from specifications, not provided by authors, it seems like promise-calling is less necessary: you can just update the specifications to always return promises. That would be my advice.

[equalsJeffH]

ok, thx, I'll give that a shot :)
