NAME ^

Devel::Eval - Allows you to debug string evals

SYNOPSIS ^

  use Devel::Eval 'dval';
  
  dval "print 'Hello World!';";

DESCRIPTION ^

In the Perl debugger, code created via a string eval is effectively invisible. You can run it, but the debugger will not be able to display the code as it runs.

For modules that make heavy use of code generation, this can make debugging almost impossible.

Devel::Eval provides an alternative to string eval that will do a string-eval equivalent, except that it will run the code via a temp file.

Because the eval is being done though a physical file, the debugger will be able to see this code and you can happily debug your generated code as you do all the rest of your code.

FUNCTIONS ^

dval

The dval function takes a single parameter that should be the string you want to eval, and executes it.

Because this is intended for code generation testing, your code is expected to be safe to run via a 'require' (that is, it should return true).

SUPPORT ^

Bugs should be always be reported via the CPAN bug tracker at
