NAME

       Text::MicroMason::TextTemplate - Alternate Syntax like Text::Template

SYNOPSIS

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

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

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

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

       Text::Template provides a syntax to mix Perl into a text template:

         { my $hour = (localtime)[2];
           my $daypart = ( $hour > 11 ) ? 'afternoon' : 'morning';
         '' }
         Good { $daypart }, { $name }!

DESCRIPTION

       This mixin class overrides several methods to allow MicroMason to emulate the template syntax and some of
       the other features of Text::Template.

   Compatibility with Text::Template
       This is not a drop-in replacement for Text::Template, as the Perl calling interface is quite different,
       but it should be able to process most existing templates without major changes.

       This should allow current Text::Template users to take advantage of MicroMason's one-time compilation
       feature, which in theory could be faster than Text::Template's repeated evals for each expression.  (No
       benchmarking yet.)

       Contributed patches to more closely support the syntax of Text::Template documents would be welcomed by
       the author.

   Template Syntax
       The following elements are recognized by the TextTemplate lexer:

       •   literal_text

           Anything not specifically parsed by the below rule is interpreted as literal text.

       •   { perl_expr }

           A Perl expression to be interpolated into the result.

               Good { (localtime)[2]>11 ? 'afternoon' : 'morning' }.

           The block may span multiple lines and is scoped inside a "do" block, so it may contain multiple Perl
           statements and it need not end with a semicolon.

               Good { my $h = (localtime)[2]; $h > 11 ? 'afternoon'
                                                      : 'morning'  }.

           To make a block silent, use an empty string as the final expression in the block.

               { warn "Interpreting template"; '' }
               Hello there.

           Although the blocks are not in the same a lexical scope, you can use local variables defined in one
           block in another:

               { $phase = (localtime)[2]>11 ? 'afternoon' : 'morning'; '' }
               Good { $phrase }.

   Argument Passing
       Like Text::Template, this package clobbers a target namespace to pass in template arguments as package
       variables. For example, if you pass in an argument list of "foo => 23", it will set the variable $foo in
       your package.

       The strict pragma is disabled to facilitate these variable references.

       Internally, this module inherits this functionality from the PassVariables mixin. If you are using the
       TextTemplate mixin, do not also specify the PassVariables mixin or it will be included twice. For more
       information, see Text::MicroMason::PassVariables.

   Supported Attributes
       package
           Target package namespace.

   Private Methods
       prepare()
           If a package has not been specified, this method generates a new package namespace to use only for
           compilation of a single template.

       lex()
           Lexer for matched braces - produces only text and expr tokens. Uses Text::Balanced.
