NAME

Eval::TypeTiny - utility to evaluate a string of Perl code in a clean environment

DESCRIPTION

This is not considered part of Type::Tiny's public API.

Functions

This module exports one function, which works much like the similarly named function from Eval::Closure:

eval_closure(source => $source, environment => \%env, %opt)

Constants

The following constant may be exported, but is not exported by default.

HAS_LEXICAL_SUBS

Boolean indicating whether Eval::TypeTiny has support for lexical subs. (This feature requires Perl 5.18.)

EVALUATION ENVIRONMENT

The evaluation is performed in the presence of strict, but the absence of warnings. (This is different to Eval::Closure which enables warnings for compiled closures.)

The feature pragma is not active in the evaluation environment, so the following will not work:

   use feature qw(say);
   use Eval::TypeTiny qw(eval_closure);
   
   my $say_all = eval_closure(
      source => 'sub { say for @_ }',
   );
   $say_all->("Hello", "World");

The feature pragma does not "carry over" into the stringy eval. It is of course possible to import pragmas into the evaluated string as part of the string itself:

   use Eval::TypeTiny qw(eval_closure);
   
   my $say_all = eval_closure(
      source => 'sub { use feature qw(say); say for @_ }',
   );
   $say_all->("Hello", "World");
