NAME

HTML::Template::Pro - Perl/XS module to use HTML Templates from CGI scripts

CONTENTS

SYNOPSIS

It is moved out and split.

See SYNOPSIS in HTML::Template::SYNTAX for introduction to HTML::Template and syntax of template files.

See SYNOPSIS in HTML::Template::PerlInterface for perl interface of HTML::Template, HTML::Template::Expr and HTML::Template::Pro.

DESCRIPTION

Original HTML::Template is written by Sam Tregar, sam@tregar.com with contributions of many people mentioned there. Their efforts caused HTML::Template to be mature html tempate engine which separate perl code and html design. Yet powerful, HTML::Template is slow, especially if mod_perl isn’t available or in case of disk usage and memory limitations.

HTML::Template::Pro is a fast lightweight C/Perl+XS reimplementation of HTML::Template (as of 2.9) and HTML::Template::Expr (as of 0.0.7). It is not intended to be a complete replacement, but to be a fast implementation of HTML::Template if you don’t need querying, the extended facility of HTML::Template. Designed for heavy upload, resource limitations, abcence of mod_perl.

HTML::Template::Pro has complete support of filters and HTML::Template::Expr’s tag EXPR=<expression>, including user-defined functions and construction <TMPL_INCLUDE EXPR=...>.

HTML::Template work cycle uses 2 steps. First, it loads and parse template. Then it accepts param() calls until you call output(). output() is its second phase where it produces a page from the parsed tree of template, obtained in the 1st step.

HTML::Template::Pro loads, parse and outputs template on fly, when you call $tmpl->output(), in one pass. The corresponding code is written in C and glued to Perl using Perl+XS. As a result, comparing to HTML::Template in ordinary calls, it runs 10-25 times faster. Comparing to HTML::Template with all caching enabled under mod_perl, it still 1-3 times faster. At that HTML::Template caching requires considerable amount of memory (per process, shareable, or on disk) to be permanently filled with parsed trees, whereas HTML::Template::Pro don’t consumes memory for caches and use mmap() for reading templates on disk.

Introduction to HTML::Template and syntax of template files is described in HTML::Template::SYNTAX. Perl interface of HTML::Template and HTML::Template::Pro is described in HTML::Template::PerlInterface.
