An error handler for rlang::check_dots_used() that issues a warning that only lists argument names.

Description

This handler parses the error message produced by rlang::check_dots_used(), extracting the names of the unused arguments, and formats them into a more gentle warning message. It relies on rlang maintaining its current format.

Usage

unused_dots_warning(e)

Arguments

e	a condition object, typically not passed by the end-user; see example below.

Examples

g <- function(b=NULL, ...){
  invisible(force(b))
}

f <- function(...){
  rlang::check_dots_used(error = unused_dots_warning)
  g(...)
}

f() # OK
f(b=2) # OK
f(a=1, b=2, c=3) # Warning about a and c but not about b
