Unclear guidance: Please update the system requirement in DESCRIPTION file #104

Open malcolmbarrett opened 3 years ago

use_extendr() requests: Please update the system requirement in DESCRIPTION file. I think this could be a bit clearer. Is there some generally useful boilerplate, e.g. what is in rextendr's DESCRIPTION (Rust 'cargo'; the crate 'libR-sys' must compile without error), that use_extendr() could offer?

In addition to offering clearer guidance here, we could suggest desc and modify it ourselves if installed, as usethis often does (desc is an implicit suggested pkg currently via devtools/usethis).

I'm not even sure what exactly should be in the system requirements. That's maybe the first thing to figure out.

malcolmbarrett commented 3 years ago

Yes, that makes sense. There's probably a related issue here with guiding users on their toolchain setup when rextendr can't successfully run. Something like rust_sitrep(), similar to usethis::git_sitrep(), that reports what rextendr can find and make suggestions about troubleshooting
