The motivation for this change is purely to give better developer ergonomics. Correct. To be able to understand much more from the backtrace without needing as much to look in every file:line. > It sounds like you're saying I should make a separate proposal for that? Yes. (for that use case I think it's much better if you can use e.g. `caller_locations`/`Thread::Backtrace::Location` to achieve the output you want, or just post-process the output). ---------------------------------------- Feature #19117: Include the method owner in backtraces, not just the method name https://bugs.ruby-lang.org/issues/19117#change-100061 * Author: byroot (Jean Boussier) * Status: Open * Priority: Normal ---------------------------------------- ``` module Foo class Bar def inspect 1 + '1' end end end p Foo::Bar.new ``` This code produce the following backtrace: ``` /tmp/foo.rb:4:in `+': String can't be coerced into Integer (TypeError) from /tmp/foo.rb:4:in `inspect' from /tmp/foo.rb:9:in `p' from /tmp/foo.rb:9:in `
' ``` This works, but on large codebases and large backtraces the method name isn't always all that revealing, most of the time you need to open many of the locations listed in the backtrace to really understand what is going on. I propose that we also include the owner name: ``` /tmp/foo.rb:4:in `Integer#+': String can't be coerced into Integer (TypeError) from /tmp/foo.rb:4:in `Foo::Bar#inspect' from /tmp/foo.rb:9:in `Kernel#p' from /tmp/foo.rb:9:in `
' ``` I believe that in many case it would allow to much better understand the backtrace without having to jump back and forth between it and the source code. This is inspired by @ivoanjo 's `backtracie` gem: https://github.com/ivoanjo/backtracie -- https://bugs.ruby-lang.org/ Unsubscribe:
