Support tidyr functions?

[etiennebacher]

Hello, I don't see functions from tidyr that I find quite useful in data wrangling, such as separate() or unite(). Is the support for tidyr S3 methods on the roadmap or is it out of scope for the package?

Thanks

Thanks. I believe it's in scope, but could tidyr also be changed in such a way that it works out of the box with duckplyr?

[etiennebacher]

I don't understand the question but maybe it's just because I'm not familiar with duckplyr's internals. Isn't duckplyr adding methods for dplyr's S3 generics? If so, couldn't the same be done with tidyr's generics, and why would it require changes in tidyr?

[krlmlr]

Just hypothetically: if tidyr could rely on dplyr and on duckplyr-supported functions, we wouldn't need to do anything here. Looking at the implementation of tidyr:::separate.data.frame(), this seems elusive, though. More specifically, at least the extra = "warn" and fill = "warn" arguments, and also convert, will be difficult to implement.

Happy to review a sketch for an S3 method here.

Just to clarify in case someone else is interested in this, I don't plan on making a sketch of this S3 method (for the coming weeks at least).
