You can look at math.statistics:collect-by as a reference:

USE: math.statistics

{ "hello" "hola" "ball" "scala" "java" "factor" "python" } [ length
] collect-by

Re: [Factor-talk] "group-by" word

[P.]

Do it step by step - think about the steps you need to take.
I would first sort the array by length.
Then I would group them by length (look at the monotonic-split word for that).
That would be very close to what you want.

[Factor-talk] "group-by" word

[missingfaktor]

I want to write a word "group-by" that has following stack effect and
behavior:

Signature:

: group-by ( seq quot -- alist ) (group-by-impl) ;

Input:

{ "hello" "hola" "ball" "scala" "java" "factor" "python" } [ length ]
group-by

Output:

H{
  { 5 { "hello" "scala" } }
  { 4 { "hola" "ball" "java" } }
  { 6 { "factor" "python" } }
}

I tried this many times, but failed. Can someone please provide me an
implementation for this, preferably with an explanation?

Re: [Factor-talk] Where can I get this Factor Listener?

[John Benediktsson]

What about it is less convenient?

IIRC, one of the main motivations for the change was to show what the stack
looks like between computations, rather than just the current values.

The listener you get now is the same one as in the video. The only
difference from the video is how the data stack is displayed. I think it
was changed so that the data stack would also be displayed during terminal
listener sessions.

[missingfaktor]

Where can I get the Factor Listener used in this video:
http://www.youtube.com/watch?v=f_0QlhYlS8g?

The one I downloaded from the project site is different and less convenient
to use.
