[Factor-talk] traslation

[Arkady Rost]

Hi! I'm looking for a more elegant solution of the following task.

for i in rangeA {
for j in rangeB {
foo(param, i, j);
}
bar();
}

I need to translate this to factor.

foo(param, y, x) <=> x y param foo

I have a solution:
rangeA rangeB param [ foo ] curry [ swapd [ call ] 2curry each bar ] 2curry
each

For example,
rangeA = { "a" "b" "c" }
rangeB = { "1" "2" "3" }
param = " "
foo = append append write ;
bar = "" print ;

{ "a" "b" "c" } { "1" "2" "3" }  " " [ append append write ] curry [ swapd [
call ] 2curry each "" print ] 2curry each

Result is :
1a 2a 3a
1b 2b 3b
1c 2c 3c

I think my solution is bloated with partial applications. Maybe someone can
provide a better way to solve this task.

Cheers,
Ark. Rost

The original task is more complicated that's why I've used foo and bar in
definition of the problem. Thanks for attention but I'm looking for a better
solution in the general case.

Thanks for all ideas. They are really helpful. Now I have a lot of things to
think about.

[Factor-talk] some questions

[Arkady Rost]

Hi! I have two questions.

1) How to declare a stack effect for such function?
: foo ( ?? -- ??? ) dup 5 = [ ] [ drop foo ] if ; inline recursive

2) How the word with-compilation-unit applies changed words?
It's invoked with with-scope word witch discards any variable set by the
quotation.

Cheers,
Arkady Rost

[Factor-talk] stack effect

[Arkady Rost]

Hi!
Today I was trying to write some factor code and it turned out that I can
write such code:
*1 5 4 3 2 [ 5 = not ] loop*
It works and produces stack with one element 1. I expect that at least I
would have a warning because loop word takes quotation with ( ... -- ... ?
) stack effect. In the example I use quotation with ( x -- x ) stack
effect. So what I am missing?

Cheers,

Hello, factorians!

What's happening with factorcode.org? I've got the message that "This
