NAME
Text::MicroMason - Simplified HTML::Mason Templating
SYNOPSIS
# Mason templates provide several ways to mix Perl and text
$template = <<'END_TEMPLATE';
% if ( $ARGS{name} eq 'Dave' );
I'm sorry <% $ARGS{name} %>, I'm afraid I can't do that right now.
% } else {
<%perl>
my $hour = (localtime)[2];
my $greeting = ( $hour > 11 ) ? 'afternoon' : 'morning';
%perl>
Good <% $greeting %>, <% $ARGS{name} %>!
% }
END_TEMPLATE
# Use the execute function to parse and evalute a template
use Text::MicroMason qw( execute );
print execute($template, 'name'=>'Dave');
# Or compile it into a subroutine, and evalute repeatedly
use Text::MicroMason qw( compile );
$coderef = compile($template);
print $coderef->('name'=>'Dave');
print $coderef->('name'=>'Bob');
MOTIVATION
The HTML::Mason module provides a useful syntax for dynamic template
interpretation (sometimes called embedded scripting): plain text (or
HTML) containing occasional chunks of Perl code whose results are
interpolated into the text when the template is "executed."
However, HTML::Mason also provides a full-featured web application
framework, and sometimes I'd like to use this capability without
configuring a full Mason installation.
Thus, the Text::MicroMason module was born: it supports the core aspects
of the HTML::Mason syntax ("<%perl>...%perl>", "<%...%>", "%...\n",
"%ARGS" and "$_out->()" ), and omits the features that either require
file access (like autohandlers and "<& file &>" includes) or are less
widely used (like "<%method>" blocks).
SEE ALSO
See the HTML::Mason manpage for a much more full-featured version of the
capabilities provided by this module.
If you've already got HTML::Mason installed, configured, and loaded into
your process, you're probably better off using it; the $interp-
>make_component() method allows you to parse a text string without
saving it to disk first.
Related Modules
You may well be thinking "yet another dynamic templating module?
Sheesh!" And you'd have a good point. There certainly are a variety of
templating toolkits on CPAN already; even restricting ourselves to those
which use Perl syntax for both interpolated expressions and flow control
(as opposed to "little languages") leaves a fairly crowded field,
including Template::Toolkit, Template::Perl, Text::Template, and
Text::ScriptTemplate, as well as those that are part of full-blown web
application frameworks like Apache::ASP, ePerl, HTML::Embperl, and
HTML::Mason.
Nonetheless, I think this module occupies a useful niche: it provides a
reasonable subset of HTML::Mason syntax in a very light-weight fashion.
In comparison to the other modules listed, MicroMason aims to be fairly
lightweight, using one eval per parse, converting the template to an
cacheable unblessed subroutine ref, eschewing method calls, and
containing just 70-ish lines of Perl.
INSTALLATION
This module should work with any recent version of Perl 5; there are no
prerequisite modules beyond the standard distribution.
Retrieve the current distribution from here:
http://work.evolution.com/dist/
Download and unpack the distribution, and execute the standard "perl
Makefile.PL", "make test", "make install" sequence.
VERSION
This is version 1.0.3 of Text::MicroMason.
This module should work with any version of Perl 5, without platform
dependencies or additional modules beyond the core distribution.
Module Naming Issues
Although originally derived from HTML::Mason, I have moved this module
from the HTML namespace to Text, as it doesn't specifically address HTML
or web technologies
This module should be categorized under group 11, Text Processing,
although there's also an argument for placing it 15 Web/HTML, where
HTML::Mason appears.
