8.11 The flavor Function
The flavor
function, like the origin
function, does not operate on the values of variables but rather it tells you something about a variable. Specifically, it tells you the flavor of a variable (see The Two Flavors of Variables).
The syntax of the flavor
function is:
$(flavor variable)
Note that variable
is the name of a variable to inquire about, not a reference to that variable. Therefore you would not normally use a ‘$
’ or parentheses when writing it. (You can, however, use a variable reference in the name if you want the name not to be a constant.)
The result of this function is a string that identifies the flavor of the variable variable
:
- ‘
undefined
’ - if
variable
was never defined. - ‘
recursive
’ - if
variable
is a recursively expanded variable. - ‘
simple
’ - if
variable
is a simply expanded variable.
