name needs a default value in use_rcpp() or we should check name earlier and exit early and informatively if not provided.
Introduced in 3c03f5c.
use_rcpp() now errors if called without name and the error is pretty confusing:
Error in `use_rcpp()`:
! Open file must be a code or test file.
It's actually coming from the internal helper compute_name(). This (inherited) documented behaviour:
#' @param name Either a string giving a file name (without directory) or
#' `NULL` to take the name from the currently open file in RStudio.
doesn't make any sense for use_rcpp(), i.e. what does the currently open file have to do with it. And, as I just found, there might not even be a currently open file.
Check if this affects other functions, e.g. use_c(), that were also touched.
