NAME

       Text::MicroMason::DoubleQuote - Minimalist Interpolation Engine

SYNOPSIS

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

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

       Templates can be written using Perl's double-quote interpolation syntax:

	   $coderef = $mason->compile( text => 'Hello $ARGS{name}!' );
	   print $coderef->( name => 'World' );

DESCRIPTION

       Text::MicroMason::DoubleQuote uses Perl's double-quoting interpolation as a minimalist syntax for templating.

       Of course you don't need this module for simple cases of interpolation, but if you're already using the MicroMason framework to process
       template files from disk, this module should allow you to make your simplest templates run even faster.

       To embed values other than simple scalars in a double-quoted expression you can use the ${ expr } syntax. For example, you can interpolate
       a function call with "${ ( time() ) }" or "@{[mysub(1,2,3)]}". As noted in perldaq4, "this is fraught with quoting and readability
       problems, but it is possible." In particular, this can quickly become a mess once you start adding loops or conditionals. If you do find
       yourself making use of this feature, please consider switching to one of the more powerful template syntaxes like
       Text::MicroMason::HTMLMason.

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.
