NAME ^

Devel::EvalContext - Save lexicals and hints between calls to eval

SYNOPSIS ^

  use Devel::EvalContext;
  my $cxt = Devel::EvalContext->new;
  $cxt->run(q{ my $a = 5; });
  $cxt->run(q{ print $a; });

DESCRIPTION ^

Sometimes it's necessary to run some code that creates lexicals and then run more code that uses the same ones. Perhaps it's in an interactive development environment.

However, unlike Scheme, perl's eval primitive doesn't take an extra parameter to specify the environment to evaluate inside of. This module corrects this deficit.

METHODS ^

new

Create a new, empty context. It has no lexicals and hints are set to zero.

run

Equivalent to eval but with a context specified.

SUPPORT ^
