WebDyne::Util

NAME

WebDyne::Util - debugging and error-stack utility functions for WebDyne

SYNOPSIS

use WebDyne::Util;

debug('message: %s', $value);
err('something failed');
my $msg = errstr();

DESCRIPTION

WebDyne::Util provides the common debugging, error-stack, and error-formatting functions used throughout the WebDyne codebase.

It exports the standard utility functions by default and uses environment variables such as WEBDYNE_DEBUG, WEBDYNE_DEBUG_FILE, WEBDYNE_DEBUG_FILTER, and related settings to control runtime debug output.

perl_inc_dn is exported by default and can also be requested explicitly. apache_startup and apache_shutdown are available on request, or through the :all export tag.

FUNCTIONS

  • debug($message, @args)

    Emit a formatted debug message if debugging is enabled for the calling package or environment.

  • err($message, @args)

    Push an error message onto the WebDyne error stack.

  • errstr()

    Return the current error string.

  • errclr()

    Clear the current error state.

  • errsubst(...)

    Apply error-text substitutions and formatting helpers.

  • errdump(...)

    Produce a formatted dump of the current error stack and related diagnostics.

  • errstack()

    Return the current error stack.

  • errnofatal($bool)

    Control whether errors are treated as fatal by the utility layer.

  • perl_inc_dn()

    Return non-default library directories from @INC.

  • apache_startup(\%options)

    Start an Apache::Test runner instance with a caller-supplied postamble.

  • apache_shutdown($runner)

    Stop an Apache::Test runner instance if it is active.

NOTES

This module is foundational to the rest of WebDyne. Most other modules import it for debug and error handling.
