Check that dots are unused

Sometimes you just want to use ... to force your users to fully name the details arguments. This function warns if ... is not empty.

Arguments

env	Environment in which to look for ....
action	The action to take when the dots have not been used. One of rlang::abort(), rlang::warn(), rlang::inform() or rlang::signal().

Examples

f <- function(x, ..., foofy = 8) {
  check_dots_empty()
  x + foofy
}

try(f(1, foof = 4))
#> Error : `...` is not empty.
#> 
#> We detected these problematic arguments:
#> * `foof`
#> 
#> These dots only exist to allow future extensions and should be empty.
#> Did you misspecify an argument?
f(1, foofy = 4)
#> [1] 5
