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".
