Description

Background

There is currently no way to get "--backtrace-limit" value when outputing backtraces from my script, so I have to ignore this value and output backtraces.

In order to be able to output according to "--backtrace-limit" value, I need a API to get this value from the Ruby side.

Proposal

I propose a readonly built-in variable "$-B" to get "--backtrace-limit" value.

# ruby --backtrace-limit=3 script.rb

puts $-B # => 3
