HTML::Template::Pro - Perl/XS module to use HTML Templates from CGI scripts
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.
Original HTML::Template is written by Sam Tregar, firstname.lastname@example.org 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
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()
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
, 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()
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.
