Package osh :: Module error

Module error

Controls handling of exceptions and stderr through the setting of handlers.

An exception_handler is a function with these arguments:

exception: The exception being handled. In case of a remote exception, this exception object is a client-side reconstruction of the server-side exception.
op: A command of type Op, or, in case of a remote exception, a command description, obtained by applying str().
input: Input to the command that raised the exception.
host: The host on which the exception occurred, or None if local.

An error_handler is a function with these arguments:

line: A line written to stderr.
op: A command of type Op, or, in case of remote stderr output, a command description, obtained by applying str().
input: Input to the command that generated the stderr output.
host: The host on which the stderr output occurred, or None if local.
