nameof

nameof(expr) 🡒 text, const

A nameof expression returns a text value representing the expression passed as argument, such as nameof(1 + 2) returning "1 + 2". The argument is not evaluated !

As a special case, nameof(T.X) returns X instead of T.X, and nameof("XYZ") returns "XYZ" instead of "\"XYZ\"".

The following example

table Example = with
  [| as Index, as Country, as CapitalCity |]
  [| 1,        "France",   "Paris"        |]
  [| 2,        "Greece",   "Athens"       |]
  [| 3,        "Hungary",  "Budapest"     |]
  [| 4,        "Italy",    "Rome"         |]

chosen = 2
where Example.Index == chosen
  capitalH = nameof(Example.CapitalCity)
  country = single(Example.Country)
  capital = single(Example.CapitalCity)
  show scalar "" a1c1 with "\{capital} is the \{capitalH} of \{country}."

will display Athens is the CapitalCity of Greece..
