Handle noisy compiler output
One of my packages links to RcppEigen, which generates a huge volume ~10,000 lines of noisy but irrelevant warnings (e.g. unknown pragma) by default, as of course required by CRAN. This relates to https://github.com/r-hub/rhub/issues/42 .
With some gymnastics, I can send R CMD INSTALL args via R CMD check args, via rhub::check, but these only apply to the tested package itself, not dependencies. There is no way I can find to pass any compiler flags to an rhub docker build. As was suggested in https://github.com/r-hub/rhub/issues/42 , folding sections in the HTML output would be a workaround.
No doubt more complicated would be configurable compiler flags for both package itself and dependencies. Or possibly, optionally passing a custom~/.R/Makevars through.
Is something like this going to work?
rhub::check(env_vars = "MAKEFLAGS=\"CXXFLAGS=-no-unknown-pragmas\"")
(via https://cran.r-project.org/doc/manuals/r-release/R-exts.html#Creating-shared-objects)
Will do. The thought occurred to me after the original issue, and haven’t had time to do so yet. Will report back.

It would be great if the output had folding sections. On linux, for instance, the user is seldom interested in the 10,000 lines of package install info. All sections could be folded by default to just show a "table of contents".
Also a "go to bottom" button would be great for 20,000 line reports. note: on a phone screen, the lack of navigation makes the output unusable: there's just no way to scroll to the bottom of a 20000-line unix install in less than a few minutes of scrolling.
not claiming orginality here: Both are travis features
This issue is about the previous R-hub system, it does not apply to the new system, so I am closing it now. Please see https://r-hub.github.io/rhub/ for the new system, R-hub v2.
