Trying to understand macro scope (Tidier package)

General Usage
22

Actually, you can wrap this inside of an anonymous function where you call the anonymous function as soon as define it with a (x -> fn(x))(arg1, arg2) syntax.

Here’s the short version.

@chain df begin
  @mutate(a_label = ~categorical((x -> @sprintf("Var = %.1f", x))(a)))
end

…and here I’ve broken it up into 2 steps for readability…

@chain df begin
  @mutate(a_label = (x -> @sprintf("Var = %.1f", x))(a))
  @mutate(a_label = ~categorical(a_label))
end

Anonymous functions in TidierData.jl should mostly only be needed in situations where your code uses macros (or where you’re using across()).
