Is it possible to redirect $stderr to a Logger isntance?

[Iñaki Baz Castillo]

Hi, is it possible to redirect $stderr to any available logger instance (as=
=20
Logger, SyslogLogger, Logging)?

I think it cannot be done, since current Loggers can log to $stderr so we=20
would get some kind of "loop" XD

Thanks for any comment.

$stderr is a file descriptor. You can reopen the descriptor to any other =
valid descriptor: file, socket, pipe, unix socket, etc.

For any of the loggers you mentioned above, get a hold of the internal =
descriptor the logger is using and then ....

new_fd =3D logger.get_logger_file_descriptor
$stderr.reopen new_fd

Thanks. The problem is that Syslog is a daemon rather than a file descripto=
r.=20
This is: Syslog is a daemon which receives messages from syslog clients and=

log them to files or databases.

However I was able to use Syslog as $stderr as follows (thanks to Eric):


require 'syslog_logger' # Logger/Syslog converter

class MySyslogLogger < SyslogLogger
alias puts error
alias write error
def flush; self; end
end

$stderr =3D MySyslogLogger.new('foo')
