Have a way to type a large code in codeplayground?

Question

How to type codes like 250 ruls in the codeplay ground?

Answer 1

if by "250 'ruls' " you mean 250 lines then you don't. just write the code in your favourite editor or IDE and copy paste the code from that to the codeplayground.

Answer 2

I'm writting some about near thousand lines of code in playground... on a tablet, and with a hard keyboard ;P
