Text::MicroMason::DoubleQuote - Minimalist Interpolation Engine


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' );


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.


To refer to arguments as $name rather than as $ARGS{name}, see Text::MicroMason::PassVariables.
