Table Transformer: How to use js functions that expect a callback function as parameter?

[Stephan Bauer]

For example the ->map() function of arrays expects a function as parameter which is then executed on every item of the array.

How do I pass this function when calling from within the table fransformer plugin?

So I want do something like this:

SELECT *,
       T1.Sprint->split(" ")->map(->match(("[0-9][0-9].[1-5].([1-6]|IP)")->0)
FROM T1

Any ideas?

P.S. Markup for an example table

||Key||Sprint||

Hi @Stephan Bauer,

I see that you have a similar question here, so please let’s move to that thread.

Yes, but no ;-)

The use case I picked is the same but the map function of arrays is just picked as an example here.

The underlying question, I would like to get an answer to, is the one stated in the tite:

How to use js functions that expect a callback function as parameter?

Since I ran into this already multiple times and did not get it working I am interested if this is possible or not.

Best regards,
Stephan

Hi @Stephan Bauer,

Unfortunately, you can't use js functions that have arguments as functions either. This comes from the security side of the app.

OK, thanks for the clarification.
