NAME¶

Log::Any::Proxy::WithStackTrace - Log::Any proxy to upgrade string errors to objects with stack traces

VERSION¶

version 1.713

SYNOPSIS¶

  use Log::Any qw( $log, proxy_class => 'WithStackTrace' );
  # Some adapter that knows how to handle both structured data,
  # and log messages which are actually objects with a
  # "stack_trace" method:
  #
  Log::Any::Adapter->set($adapter);
  $log->error("Help!");   # stack trace gets automatically added

DESCRIPTION¶

Some log adapters, like Log::Any::Adapter::Sentry::Raven, are able to take advantage of being passed message objects that contain a stack trace. However if a stack trace is not available, and fallback logic is used to generate one, the resulting trace can be confusing if it begins relative to where the log adapter was called, and not relative to where the logging method was originally called.

With this proxy in place, if any logging method is called with a message that is a non-reference scalar, that message will be upgraded into a "Log::Any::MessageWithStackTrace" object with a "stack_trace" method, and that method will return a trace relative to where the logging method was called. A string overload is provided on the object to return the original message.

Important: This proxy should be used with a Log::Any::Adapter that is configured to handle structured data. Otherwise the object created here will just get stringified before it can be used to access the stack trace.
