Quickstart

copy, x y ^ 5 % !to the console (right handside) then Shift+Enter

to clear a screen just hit Esc

Guides

flure use reverse polish notation (RPN) eg 10 10 + will return 20

x and y correspond to x,y coordinates

arithmatics = +, -, *, /

bitwise = &, |, ^, <<, >>

stack = pop, push, show

function declaration (or word in FORTH's term): <args> ; eg. : loop 1 - dup 0 = if else loop then ;

compile mode = :, delimited compile mode = ;

basic control flow <case> if <if_case> else <else_case> then ;

comments = ( <...comments> )

immediately call a function = eg. : bob 20 20 + ; immediate, will return 40 without calling bob

core = (-1 = true, 0 = false)

to exit = bye

Examples

each line below will computes a different results

[note] current computed image size = 128px * 128px (these numbers (128 and 128) can be substituted by w and h).

x y ^ 5 % !

x y + abs x y - abs 1 + ^ 2 << 5 % !

x 2 * y % !

x w 2 / - w 4 / * y w 2 / - % !
