UTILITY METHODS
make_message($segment, $message, @items)
Formats and returns the message according to the debug/verbose levels of $segment and the provided arguments.
There are two-three parts to the message:
segment_name: message <items>The message part is simply $message for all debug/verbose levels.
The <items> part is only included when the verbosity level of the segment is greater than 1. It is formatted by Data::Dump.
If the verbosity and debug levels are both 0, segment_name is simply the segment's label. If the verbosity level of the segment is greater than zero, the full path of the segment is used instead of label. If the debug level of the segment is greater than 1, the segment's id is appended to label/path in parentheses.
debug_level($segment)
verbose_level($segment)
These methods determine the appropriate debug and verbosity levels for the given $segment, while respecting any environment variable overrides.
Available environment variable overrides:
