Issue #20864 has been updated by Eregon (Benoit Daloze). Why not include the error directly in the warning message? It seems that would just work better with the whole `Warning.warn` system and existing handling of warnings. ---------------------------------------- Feature #20864: Support `error:` keyword to `Kernel#warn` https://bugs.ruby-lang.org/issues/20864#change-110396 * Author: ioquatix (Samuel Williams) * Status: Open ---------------------------------------- `Kernel#warn` is extremely useful. It is possible to include some details about the current caller using `uplevel` for the current call stack. But it is not possible to include details about errors. I'd like to propose another extension to log errors. ```ruby begin # some work rescue => error warn "An error occurred!", error: error end ``` Such a feature would allow us to log errors using a standard interface. I don't have an opinion about the implementation, but I wanted to get feedback on the interface. -- https://bugs.ruby-lang.org/
