Therefore, pay as much attention to the ending of something as to the beginning."

HiConsole is for people who want to have classic computing-type fun with their fancy modern machines.

To get started quickly, go to the homepage and click on Launch HiConsole. Try the dropdown commands list over the "Input" box. More Examples are listed below the diagram.

--- Simple Math:

(+ 100 5)
(+ 100 5 (* 1 2))

--- Set a value:

(set 'six 6)
(+ 7 six (set 'twelve 12))

--- Define a function:

(define square (e) (* e e))
(square 5)
(define average (x y) (/ (+ x y) 2))
(average 5 50.2)

--- Conditional:

(cond ((= 1 1) (+ 2 3) ) )

--- JavaScript:

j 100*5*(1+2)
 j 4/3.0002

--- Raphaël graphics:

r whiteoval ellipse(220,166,80,100)
r whiteoval attr stroke-width 8
r whiteoval attr fill white
r whiteoval click output1("whiteoval","hi");
r whiteoval attr opacity 0.2 (confuses IE!)
j whiteoval.rotate(45); (note: JavaScript!)

--- Turtle control:

j placeTurtle(100,200);

lisp expressions

single line

(* 100 5 (+ 1 2)) 

Multiply 100, 5, and the sum of 1 and 2.

[should output: 1500 ]

(+ (* 3 5) (* 47 (- 20 6)) 12)

Add 3 times 5 to: 47 times the result of 20 minus 6, and 12.

[should output: 685 ]

(+	(* 3 6)
      (* 47 
      (- 20 6))
      12)

Please add up these three numbers.
The first is the (multiply result) of 3 and 6.
The second is the multiply result of 47, and 20 minus 6.
The third and last is 12.

[should output: 688 ]

(cond ((= 1 1) (+ 2 3) ) )

I want to know whether 1 is equal to 1.
If it is, please give me back the sum of 2 and 3.

[should output: 5 ]

(define (pi-sum a b)
    (if (> a b)
    0
    (+ (/ 1 (* a (+ a 2)))
        (pi-sum (+ a 4) b))))

[left as an exercise to the reader.]

define

(define a (* 5 5))

define a to be the square of 5 and 5.

(* (* a a) (* a a))

?= -> 625

(define abs (x) (cond ((< x 0) (- x)) ) )

[outputs: (lambda (x) (cond ((< x 0) (- x)))) ]

(abs -33)

[outputs: 33 ]

JavaScript commands

j lispCommands.join("~");

[should output: list of lisp definitions]

j jslLookup("cdadr")

[should output: e,cdr,car,cdr,e ]

j 100*5*(1+2)

[should output: 1500 ]

j 4/3.0002

[should output: 1.3332444503699754 ]

Raphaël Graphics commands

r whiteoval ellipse(220,166,80,100)
r whiteoval attr stroke-width 8
r whiteoval attr fill white
r whiteoval attr opacity 0.2
r whiteoval func debug1("whiteoval","hi");

make a white oval, set its attributes and give it a click action.

r blueline path({stroke:"#036"})
.moveTo(10,10).lineTo(50,50)
r blueline attr stroke-width 8

make a blue line.

r newtext text(300,200,"hello")
r newtext attr font-size 50px

make some text.

userinput - cause input as if user typed it in

j userinput("\
R whiteoval ellipse(220,166,80,100) fill white");
j userinput("\
R whiteoval attr stroke-width 8");
j userinput("\
R whiteoval attr stroke-opacity 0.5");
j userinput('\
R whiteoval func debug1("rfunc","hi");');

JavaScript can invoke commands in the user's voice.
