Description fjan11 2008-11-12 21:18:53 UTC

It would be great if the Netbeans editor could highlight the following problem:
some_function(:a => 1, b=> 2, a => 3)

Of course, the last key value pair overwrites the first one. Rails has functions that accept options hashes 10 items long, and I have on several occasions made 
the mistake of including an option twice, leading to hard to track down bugs.

Great idea!

This should be trivial to implement with the hints infrastructure.

Comment 2 Torbjorn Norbye 2008-11-13 02:39:03 UTC

Fixed in changeset 5a1e61e6d1a5.  That's for 7.0. I'm attaching a 6.5 compatible version as well.
