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".
