.get-var
This directive takes input of a variable name and obtains its value in the current scope. If there is no such value with that name, nothing is returned.
The .get-var
directive has associated syntactic sugar, so the following two are equivalent.
.get-var{variable}
!variable
More exclamation points can be used to widen the scope searched, hence !!var
will obtain the value of ‘var’ in the scope above its current definition.
The .get-var
directive is the counter-part to .set-var
, which sets variables to given values.
