R CMD check hooks? - Githubissues

HenrikBengtsson commented 6 years ago

Is it possible to detect/infer, during .Rprofile, whether R CMD check is running or not? (I'd expect commandArgs() would reflect this)

If so, we could add an element to startup::sysinfo() that reflects this, e.g. string r_cmd taking values build, INSTALL, and check.

And then, one could add a "hook" that reports on more information about the R session that what R CMD check reports on, e.g. what environment variables, locales, R options, .libPaths() etc. R CMD check sees. This info could be outputted to a log file in the check directory but possibly also be outputted to the terminal (unless R CMD ... redirects all that).

To detect various R CMD <command> calls, see https://github.com/wch/r-source/blob/trunk/src/scripts/, e.g.

Don't forget R.utils::queryRCmdCheck() which does something similar.

Adding

utils::str(list(
  cmdargs = commandArgs(),
  R_CMD = Sys.getenv("R_CMD")
), vec.len = +Inf)

to ~/.Rprofile reveals that calls to R CMD build ..., R CMD check ... and R CMD INSTALL ... carry the following information:
