handle_setopt() that takes list about curl

[jeroen]

It does support multiple options already. You mean something that would do: do.call(handle_setopt, list()) ?

[hadley]

Yeah, exactly

[jeroen]

Okay makes sense. Prefer a separate function or overloading curl_setopt?

[hadley]

Similarly for handle_setform().

I quite like the handle_setopt(x, ..., .list) form

[hadley]

I wonder if it would also be possible to have a convention for calling setform from within the options list?

opts <- list(setform = list(a = 1, b = form_file("abc.txt"))
handle_setopts(h, .list = opts)

What do you think? It would make my life easier to have a unified interface, but it's not a big deal.

[jeroen]

I don't feel strongly about it, the handle_setopt(x, ..., .list) form is fine. The only thing is that it is ambiguous what has to happen when an argument appears both in ... and .list.

[hadley]

I think the last argument should always win:

handle_setopt(x = 1, x = 2) # x = 2
handle_setopt(x = 1, .list = list(x = 2)) # x = 2
handle_setopt(.list = list(x = 1, x = 2)) # x = 2

etc
