Re-write captured ... arguments as a c(DESTINATION = TARGET) character vector.
Suggested capture code is: substitute(list(...)). Allows bquote .() substitution.
grab_assignments_from_dots( captured_args, unpack_environment = parent.frame(), allow_dot_on_left = FALSE )
| unpack_environment | environment to look in |
|---|---|
| allow_dot_on_left | logical if TRUE allow forms like |
| captured_dots | captured |
named character vector describing the desired mapping.
f <- function(...) { unpack_environment <- parent.frame(n = 1) orig_args <- substitute(list(...)) grab_assignments_from_dots(orig_args, unpack_environment) } f(a, c = d, e := f, g <- h, i -> j)#> c e g j #> "a" "d" "f" "h" "i"# should equal c('a', 'c' = 'd', 'e' = 'f', 'g' = 'h', 'j' = 'i')
