Carp::Clan - Report errors from perspective of caller of a "clan" of modules.
|
||
|
|
|
||
|
|
This module is based on "Carp.pm" from Perl 5.005_03. It has been modified to
|
||
|
|
skip all package names matching the pattern given in the "use" statement
|
||
|
|
inside the "qw()" term (or argument list).
|
||
|
|
Suppose you have a family of modules or classes named "Pack::A", "Pack::B" and
|
||
|
|
so on, and each of them uses "Carp::Clan qw(^Pack::);" (or at least the one in
|
||
|
|
which the error or warning gets raised).
|
||
|
|
Thus when for example your script "tool.pl" calls module "Pack::A", and module
|
||
|
|
"Pack::A" calls module "Pack::B", an exception raised in module "Pack::B" will
|
||
|
|
appear to have originated in "tool.pl" where "Pack::A" was called, and not in
|
||
|
|
"Pack::A" where "Pack::B" was called, as the unmodified "Carp.pm" would try to
|
||
|
|
make you believe :-).
|
||
|
|
This works similarly if "Pack::B" calls "Pack::C" where the exception is
|
||
|
|
raised, etcetera.
|
||
|
|
In other words, this blames all errors in the "Pack::*" modules on the user of
|
||
|
|
these modules, i.e., on you. ;-)
