Length of backtrace displayed by ruby

Ruby
1

Is there a way to remove the maximum backtrace length displayed by the
interpreter when an exception terminates the process ? It makes the
backtrace
totally useless in situations where it is long and the interesting
calls
are in the middle.

Thanks

Not yet. Do you (or anybody else) have any good API suggestion?

How about giving a full backtrace with ruby -d?

Exception.backtrace_display_limit = 42

Exception.setFilter(regularExpression)

where the matching items are removed from the backtrace.

IIRC, this only happens when the exception is handled by the top level
interpreter. If you catch the exception yourself at the top level you
can print out whatever you want, including the full stack trace.

Yes, that’s what I did as a workaround. But you have to do it for every
thread and every fork (which in my case is 4 different places)

what would be matched?

e.to_s, e.message.to_s, or e.backtrace.any?{|b|}

Class and method name was what I was thinking of.
