Feature #12026

Support warning processor

Added by jeremyevans0 (Jeremy Evans) about 5 years ago. Updated almost 5 years ago.

Target version:


This adds a simple way to filter warnings from being displayed. You
just set a $WARNING_FILTER with a regexp, and any warnings that
match the regexp will not be displayed.

I think this is a much simpler approach to filtering warnings than
feature #11588, while allowing the same type of capability.

This is backwards compatible, in that you can set $WARNING_FILTER in
previous versions of ruby without problems.

This should not cause any performance issues, as the regexp matching
isn't done until the warning message is about to be displayed.

It's possible to use something other than a global variable to store
the warning filter, but a global variable was the easiest way to
implement it, it has a global effect, and similar flags such as
$VERBOSE are also global variables, so I think a global variable
makes sense.
