selectreturns a value that follow the key (if any),
find/tailsearches for the first occurence of a value and returns a series past that value.
Another question: is where a way to have a subseries of a bigger one in a static way ?
a: [a b c d e f g h]
The subseries should be:
b: [d e]
But [d e] are just part of "A"
So if you change the B: to "[z e]"
>>> a = [a b c z e f g h]
>> a: [a b c d e f g h] == [a b c d e f g h] >> b: reduce [at a 4 2] == [[d e f g h] 2] >> head change/part b/1 [z e] b/2 == [a b c z e f g h]
>> a: [a b c d e f g h] == [a b c d e f g h] >> subseries: 4x2 == 4x2 >> head change/part at a subseries/x [z e] subseries/y == [a b c z e f g h]
@nedzadarek If you consider pnly figures, then almost. In addition, optional set-word may also precede the block
view [box draw [b: box 10x10 50x50 c: circle 30x30 30]] view [box draw [[b: box 10x10 50x50][c: circle 30x30 30]]] view [box draw [[[[[[[b: box 10x10 50x50]]] circle 30x30 30]]]]] view [box draw [b: [box 10x10 50x50]]] view [box draw [b: [b2: box 10x10 50x50]]] view [box draw [b: b2: b3: box 10x10 50x50]] view [box draw [b:]]
So, it is more like
<draw-command>: (<command> <arguments> | '['<command> <arguments>']') <draw-expression>: <set-word>* <draw-command> <draw>: <draw-expression>*
apply, but you can use tricks similar to the above one.
Well, thanks, I was just imaging if there where a simple way to load code words/values at the current program execution position. So, it FOO expected X and Y then something like
(I assume "<" mean: "insert the result of the code between parens at this point")
FOO <(BAR) Print "A"
Would be interpreted like
FOO 1 2 Print "A"
Macros is not what you want, I guess. They can't operate on values that are presented at run-time (i.e. you can't evaluate function
>> foo: func [x y][x + y] == func [x y][x + y] >> bar: does [[1 2]] == func [[1 2]] >> compose [foo (bar)] == [foo 1 2] >> do compose [foo (bar)] == 3
bar, because it doesn't exist yet).
#do [bar: [1 2]] #macro ['< paren!] func [start end][ get in preprocessor/exec start/2/1 ] probe expand [ foo <(bar) foo #do keep [[1 2]] ]
