Dear all,
I was trying to turn an SExpression into a (compact) String. My final goal
is to try to avoid "unparse$InputForm" in the sage interface.
In particular, I would prefer a solution which does not contain any
unnecessary whitespace.
I know of
FORMAT('NIL, "~S", (-1/2)::INFORM)$Lisp
but this has some undesirable side effects with the rootOf operator, which
I do not understand:
r := integrate(72000/(1+x^5),x)::INFORM
FORMAT('NIL, "~S", r)$Lisp
(5)
"(/
(+
(*
(+
(^
(+
(+
(* -3
(^
#1=(|rootOf|
(+
(+
(+
(^
#2=(|rootOf|
(+
(+
(+ (+ (^ %%E0 4) (* 14400 (
^ %%E0 3)))
(* 207360000 (^ %%E0 2)))
(* 2985984000000 %%E0))
429981696000000
00)
%%E0)
3)
...
I also tried brightPrint(r)$Lisp, which yields a very compact display (the
result is the empty SExpression, but I guess I could capture the output or
somehow modify brightPrint), but it omits whitespace in the top level list:
(8) -> brightPrint((-1/2)::INFORM)$Lisp
/-12
(8) ()
Type:
SExpression
Thanks for any hints!
Martin
