NAME
Aspect::Library::Trace - Aspect-oriented function call tracing
SYNOPSIS
use Aspect;
use Aspect::Library::Trace;
aspect Trace => call qr/^Foo::/;
Foo::foo1
Foo::foo2
Foo::foo3
Foo::foo2
Foo::foo3
Foo::foo2
Foo::foo3
DESCRIPTION
Aspect Oriented Programming is a programming paradigm that increases
modularity by enabling improved separation of concerns.
It is most useful when dealing with cross-cutting concerns that would
otherwise require code to be scattered around in many places.
Aspect::Library::Trace is an Aspect library that implements nested
functional call tracing, in the style formerly offered by the "dprofpp
-T" command provided by Devel::DProf (before that module became
unusable).
Conventional Usage
The basic usage is very simple, just create an "Trace" aspect as shown
in the "SYNOPSIS".
Load Aspect, then Aspect::Library::Trace, then create the aspect using
the "aspect" function.
Any calls to functions described in the pointcut will be printed to
"STDERR". Nesting is indicated via indenting.
Because the depth is tracked at a per-Aspect level, you should avoid
creating more than one trace Aspect or the indenting levels will be
mixed up and the output will become largely meaningless.
Import Usage
For even more convenience (and even less typing) you can use the
following shorthand 1-line form.
use Aspect::Library::Trace qr/^Module::/;
When used this way, you also don't need to "use Aspect".
