The newlisp manual has predicates.
But I like to know if there is there a builtin function to find out the type of a symbol/variable/defn which I can use such as
eg:
(type x) => "list"
(type n) => "integer"
etc...
There is no built-in function that I know of that can return the type of any newLISP expression. At best, you may be able to construct your own function that uses the existing predicate functions to return a string that is unique for each cell type.
"primitive" "import" "ffi" "quote" "expression" "lambda" "fexpr" "array"
"dyn_symbol"))
(define (typeof v)
(types (& 0xf ((dump v) 1))))
the types defined in newlisp.h
Thanks everyone.
Quote from: "ryuo"
Despite of
(let (types
'("bool" "bool" "integer" "float"
"string" "symbol" "context" "primitive"
"import-simple" "import-libffi" "quote" "list" "lambda"
"fexpr" "array"))
(types (& 0xf ((dump x) 1)))))
I have tryed to write such function, but find out that
and number of other interesting paradoxes.
