I am trying to generate strings which pass a rule, e.g.
1 < length(string) < 10
So I am using,
StreamData.string( … ) |> StreamData.filter(..)
but, for some reason, I see the data sent thru the filter is always a single character.
The filter filters out everything..
Of course, without the filter, I rarely see single character outputs.
Obviously I am missing something.
The filter in this case is for individual generated characters, instead of complete strings(?)

Can you please provide a full example of the “generator” you use and its output?

I am just realising, that
StreamData.string/2s documentation tells you that it shares options withStreamData.list_of/2. There we have:min_lengthand:max_lengthoptions. SoStreamData.string(:ascii, min_length: 2, max_length: 9)should be totally fine.mmport80
Sweet, just the answer I needed : )

Moreover, having just started parameter testing and gotten this to work, I just found a bug in a regex - this is great! : )
