Question

I have a long hash with no spaces (64+ characters) and I need to display 2 of these per row or a table. To keep the table a respectable width, I want to break these hashes into multiple lines.

I’m looking for some cool Groovy recipe for doing this or some sort of HTML style that might take care of it.

Answer 1

To show 8 chars per line, you could do:

hash.toList().collate( 8 )*.join().join( '\n' )
