NAME

       Text::MicroMason::Debug - Provide developer info via warn

SYNOPSIS

       Instead of using this class directly, pass its name to be mixed in:

	 use Text::MicroMason;
	 my $mason = Text::MicroMason->new( -Debug );

       Use the standard compile and execute methods to parse and evalute templates:

	 print $mason->compile( text=>$template )->( @%args );
	 print $mason->execute( text=>$template, @args );

       You'll see lots of warning output on STDERR:

	 MicroMason Debug create: Text::MicroMason::Base::AUTO::Debug...
	 MicroMason Debug source: q(Hello <% $noun %>!)
	 MicroMason Debug lex: text, q(Hello ), expr, q( $noun ), text, q(!)
	 MicroMason Debug eval: sub { my @OUT; my $_out = sub { push ...

DESCRIPTION

       This package provides numerous messages via warn for developer use when debugging templates built with Text::MicroMason.

   Supported Attributes
       debug
	   Activates debugging messages for many methods. Defaults to logging everything.

	   Can be set to 0 or 1 to log nothing or everything.

	   Alternately, set this to a hash reference containing values for the steps you are interested in to only log this items:

	     debug => { source => 1, eval => 1 }

	   You can also selectively surpress some warnings:

	     debug => { default => 1, source => 0, eval => 0 }

   Private Methods
       debug_msg
	   Called to provide a debugging message for developer reference. No output is produced unless the object's 'debug' flag is true.

       This is a mixin class intended for use with Text::MicroMason::Base.

NAME

       Text::MicroMason::CatchErrors - Add Exception Catching for Templates

SYNOPSIS

       Instead of using this class directly, pass its name to be mixed in:

	   use Text::MicroMason;
	   my $mason = Text::MicroMason->new( -CatchErrors );

       Use the standard compile and execute methods to parse and evalute templates:

	 print scalar $mason->compile( text=>$template )->( @%args );
	 print scalar $mason->execute( text=>$template, @args );

       Result is undef on exception, plus an error message if in list context:

	 ($coderef, $error) = $mason->compile( text=>$template );
	 ($result,  $error) = $mason->execute( text=>$template, 'name'=>'Dave' );

DESCRIPTION

       This package adds exception catching to MicroMason, allowing you to check an error variable rather than wrapping every call in an eval.

       Both compilation and run-time errors in your template are handled as fatal exceptions. The base MicroMason class will croak() if you
       attempt to compile or execute a template which contains a incorrect fragment of Perl syntax. Similarly, if the Perl code in your template
       causes die() or croak() to be called, this will interupt your program unless caught by an eval block.

       This class provides that error catching behavior for the compile and execute methods.

       In a scalar context they return the result of the call, or undef if it failed; in a list context they return the results of the call (undef
       if it failed) followed by the error message (undef if it succeeded).

   Public Methods
       compile()
	     $code_ref = $mason->compile( text => $template, %options );
	     ($coderef, $error) = $mason->compile( text=>$template, %options );

	   Uses an eval block to provide an exception catching wrapper for the compile method.

       execute()
	     $result = $mason->execute( text => $template, @arguments );
	     ($result,	$error) = $mason->execute( text=>$template, 'name'=>'Dave' );

	   Uses an eval block to provide an exception catching wrapper for the execute method.
