is there library that pretty prints java or kotlin objects via reflection? something like http://www.lihaoyi.com/PPrint/

[nfrankel]

i did that by myself once
might be a bad idea
especially if objects are related with a two-way relationship
then it never ends
or the logic to make it work is stateful
not great either

if you work with data class the print is really well

[magnumrocha]

like PPRint

[magnumrocha]

kotlin already do a nice print of fields in data classes

[christophsturm]

i just want to know if there is something. maybe i write one if there isnt.

[magnumrocha]

I think for kotlin it's don't needed, due the fact of data classes already do it for you

They have hashcode and equals builders also

[Holger Steinhauer [Mod]]

How about Lombok? It has nice @Equals and @Value annotations and minimises code in Java

[christophsturm]

well i just wanted something like `pp`in ruby for usage in the console and debugging. so it should just work with in any object, also jdk objects.

[christophsturm]

and maybe its a fun little open source library, but first i want to know whats already available.

[christophsturm]

but `ReflectionToStringBuilder`is basically exactly that. just didnt occur to me that i can use it from outside a class

It's been a bit since this conversation... but I have built exactly this:

Perfect! Can’t wait to try it.
