NAME

       Alzabo::Debug - Creates constants used to turn on debugging

SYNOPSIS

         export ALZABO_DEBUG='SQL|TRACE'

         ... load and run code using Alzabo ...

         export ALZABO_DEBUG=METHODMAKER

         ... load and run code using Alzabo ...

DESCRIPTION

       This module creates constants used by other modules in order to determine what debugging
       output should be generated.

       The interface is currently experimental.

USAGE

       Currently, the only way to turn on debugging is by setting the "ALZABO_DEBUG" environment
       variable.  This variable can contain various flags, each separated by a pipe char (|).
       Each flag turns on different types of debugging output.

       These flags must be set before Alzabo is loaded, as debugging is turned on or off through
       the use of constants.

       The current flags are:

       •   SQL

           Generated SQL and its associated bound variables.

       •   TRACE

           A stack trace will be generated any time SQL is generated.

       •   METHODMAKER

           The "Alzabo::MethodMaker" module will generate verbose output describing the methods
           it is creating.

       •   REVERSE_ENGINEER

           The modules involved in reverse-engineering will generate output describing what it
           finds during reverse-engineering.

       •   ALL

           Turn on all flags.

       For now, all debugging output is sent to "STDERR".
