Using named arguments at ...

[llrs]

I tried to use the dots in a function and then use the named arguments in glue but I couldn't make it work.

Perhaps this is related to #137 but I couldn't find if it is possible or not.

library("glue")
f <- function(...) {
    print(glue("{a} + {b}"))
    sum(...)
}
f(a = 2, b = 3)
#> Error in eval(parse(text = text, keep.source = FALSE), envir): object 'a' not found

I tried some variations with setting other environments but I didn't manage to make it work. Is this behaviour considered for glue?

You have to pass the ... to the glue call as well, e.g.

library("glue")
f <- function(...) {
    print(glue("{a} + {b}", ...))
    sum(...)
}
f(a = 2, b = 3)
#> 2 + 3
#> [1] 5

Oh, sorry. Thanks!

But you can't nested call.

library("glue")
g <- function(...) {
  f(...)
}
f <- function(...) {
  print(glue("{a} + {b}"))
  sum(...)
}
g(a = 2, b = 3)
# Error in eval(parse(text = text, keep.source = FALSE), envir) : 
#  object 'a' not found

You have to pass the ... to the glue call, in case you want someone to repeat this for you :)
