Issue #13557 has been updated by ko1 (Koichi Sasada). I'm not against but could you summarize usages? ---------------------------------------- Feature #13557: there's no way to pass backtrace locations as a massaged backtrace https://bugs.ruby-lang.org/issues/13557#change-107179 * Author: sylvain.joyeux (Sylvain Joyeux) * Status: Open ---------------------------------------- When re-raising exceptions, it is sometimes useful to "massage" the backtrace (especially in DSLs). There is currently no way to do it using only backtrace locations. This causes the new exception to have #backtrace_locations return nil, and thus makes backtrace_locations unreliable as a whole. Example: ~~~ruby def test raise ArgumentError, "", caller_locations end begin test rescue ArgumentError => e p e.backtrace_locations end ~~~ attempting to pass `caller_location` to `Kernel#raise` in the `test` method fails with ``bla.rb:2:in `set_backtrace': backtrace must be Array of String (TypeError)`` -- https://bugs.ruby-lang.org/
