This little script helps to test subroutines using SQL*Developer Run or Debug command. Just copy code from "Run PL/SQL" window and run the following onliner in a terminal. It uncomments legacy dbms_ouput code and extends capacity of varchar2 variables from 200 to 32767 chars. Now paste clipboard contents back into SQL Worksheet and run.
cat /dev/clipboard | perl -p -e 's/\/\* Legacy output://g; s/\*\///g; s/VARCHAR2\(200\)/VARCHAR2\( 32767 char \)/g;s/^\s+:.*$//g' > /dev/clipboard
