Template Toolkit Version 2.19 27 April 2007 Copyright (C) 1996-2007 Andy Wardley. All Rights Reserved This is free software; you can redistribute it and/or modify it under the same terms as Perl itself. QUICK START (see INSTALL for further details) ----------- The latest version of the Template Toolkit can be retrieved from: http://www.cpan.org/modules/by-module/Template/ Fetch and install AppConfig 1.56 if you don't already have it installed. Available from CPAN in: http://www.cpan.org/authors/Andy_Wardley/ To install the Template Toolkit: tar zxf Template-Toolkit-2.19.tar.gz cd Template-Toolkit-2.19 perl Makefile.PL make make test make install The Makefile.PL will prompt for additional configuration options, including the installation of optional template libraries, HTML documentation and examples. You can safely answer 'n' to all of these questions for a quick and basic installation. If you're running ActivePerl on a Win32 platform then you can use the Perl Package Manager (PPM) to install the Template Toolkit. Chris Winters maintains a repository of pre-compiled PPM packages which contains the Template Toolkit, AppConfig and others. For further information, see: http://openinteract.sourceforge.net/ For further details on installation, see the separate INSTALL file. DESCRIPTION ----------- The Template Toolkit is a collection of modules which implement a fast, flexible, powerful and extensible template processing system. It was originally designed and remains primarily useful for generating dynamic web content, but it can be used equally well for processing any other kind of text based documents: HTML, XML, POD, PostScript, LaTeX, and so on. It can be used as a stand-alone Perl module or embedded within an Apache/mod_perl server for generating highly configurable dynamic web content. A number of Perl scripts are also provided which can greatly simplify the process of creating and managing static web content and other offline document systems. WHAT'S NEW? ----------- Version 2.19 fixes some minor bugs in both Perl and XS versions of the Template Stash, and fixes a problem with a test in the test suite failing under Win32. It also adds the url filter as a version of what the uri filter used to do before we fixed it to do the right thing. Version 2.18 fixes a number of minor bugs. It also includes a modification to the parser grammar so that you can write expressions as arguments to subroutine, method or vmethod calls. Versions 2.17 and 2.16 were interim releases by Adam Kennedy who took care of some installation problems on Mac OSX while Andy was busy elsewhere. Version 2.15 is a major maintenance release. It applies all outstanding patches and closes all open bugs listed on http://rt.cpan.org/ It includes: * XS Stash: enhancements include support for tied hashes/arrays and "fallback" methods on objects (e.g. accessing hash and list items and calling virtual methods) * Virtual Methods: added the scalar.remove, scalar.substr, hash.delete, hash.items, hash.pairs, list.import and list.hash virtual methods. Added support for backreferences to scalar.replace and other improvements to list.push, list.unshift, list.hash, hash.list * Plugins: Added Math plugin, Bug fixes and enhancements to File, Image, URL and String plugins. Moved DBI, XML and GD plugins into separate distributions. * Numerous other bug fixes, enhancements, documentation updates, all described in detail in the Changes file. More significant is what's not in version 2.15. The DBI plugin has been moved into a separate Template-DBI distribution, the GD plugins into Template-GD, the XML plugins into Template-XML, and the Latex filters into Template-Latex. This has been done in an effort to make the Template Toolkit core distribution smaller, cleaner and easier to configure and install. Version 2.14 added Unicode support to TT, a full set of command line options for tpage, the 'caller' and 'callers' items to each template component, some enhancements to the XML::Simple plugin, and a number of minor bug fixes. See the Changes file for further details of the changes in these and earlier releases. GENERAL FEATURES ---------------- Some of the key features of the Template Toolkit are listed below. See the documentation for further detail. * simple but powerful template language * promotes a clear separation between application functionality and presentation elements * variable substitution allows binding to any Perl data types (scalars, hashes, lists, subs, objects) * conditional blocks (IF/UNLESS/ELSIF/ELSE, SWITCH/CASE) * loops and iterators (FOREACH, WHILE) * file/template inclusion (INSERT, INCLUDE, PROCESS, WRAPPER) * definition of local template components (BLOCK) * post-processing filters (FILTER) * plugin module architecture for easy extensibility (USE) * embedded Perl can be optionally enabled (PERL/RAWPERL) * full exception handling (TRY/THROW/CATCH/FINAL) * user-defined macros (MACRO) * definition of template metadata (META) * virtual methods for complex data types (e.g. list.size, hash.keys, etc.) * numerous configuration options * modular OO architecture allows extensive customisation * fast LALR(1) parser modules compiles templates according to a YACC-like grammar. * templates compiled to Perl code for efficient runtime execution * in-memory and on-disk caching of compiled templates * simple front end module (Template.pm) for ease of use * numerous plugin modules: CGI, DBI, XML, URL, Date, Table, etc * standard filters for html, case folding, regex search and replace, etc. DOCUMENTATION ------------- The Template Toolkit is provided with enough documentation to keep all but the most voracious reader happy for quite some time. The 'Changes' file in the distribution directory documents all visible changes between versions of the Template Toolkit. See the section 'VERSION COMPATABILITY' below for further details. The 'TODO' file, also in the distribution directory, lists known bugs, planned enhancements and possible new features for future versions. The 'INSTALL' file covers the configuration and installation process. The rest of the documentation is distributed in Pod and HTML formats. The Pod pages are installed when you 'make install' and can be viewed using 'perldoc', e.g. perldoc Template If you're using a Unix based system then the pages should also be converted to manpages suring the 'make install'. Thus, you can also: man Template (the man pages shouldn't have any problems relating to older versions) The HTML documentation and the means to rebuild it can be found in the 'docs' sub-directory of the installation root. If you opted to have it built at installation time, then there should be an 'html' directory within it containing the generated HTML built from the source templates. The documentation is now split into several sections. The 'Template' page is now much shorter, containing information relating to the specifics of using the Template module, and a brief summary of everything else. Information relating more generally to the Template Toolkit, features, syntax of the template language, plugins and so forth, has been split up into a number of Template::Manual::* pages. Template::Manual provides the index for the manual. perldoc Template::Manual Individual sections can be viewed as, for example, perldoc Template::Manual::Syntax perldoc Template::Manual::Directives perldoc Template::Manual::Plugins The Template::Tutorial provides an index to the tutorial documents. There are currently 2 tutorials, on generating web content, and on creating and using data files. perldoc Template::Tutorial perldoc Template::Tutorial::Web perldoc Template::Tutorial::Datafile The new template libraries distributed with the Template Toolkit have some documentation, but be warned that it is rather spartan at present. If you're interested in using these libraries then the examples (in the 'examples' sub-directory) are likely to be much more useful until the documentation catches up. perldoc Template::Library::HTML perldoc Template::Library::Splash Each of the various modules that comprise the Template Toolkit has its own associated documention. The 'Template::Modules' manpage lists these modules along with a brief description of their functions. perldoc Template::Modules See the individual pages for further detail: perldoc Template::Context perldoc Template::Parser perldoc Template::Provider If you're interested in the internals of the Template Toolkit and want to know more about how it all works, then you might like to have a look at the following: perldoc Template::Manual::Internals This document also contains important information for people wishing to hack on the Template Toolkit. The final bit of good news is that there is now a FAQ for the Template Toolkit. perldoc Template::FAQ It's now got a few question in it, and better still, some answers! Further contributions welcome. Most of the documentation is stable and reliable. Where it's not then it's usually marked as such. In particular, the documentation for the template libraries (Template::Library::*), the FAQ (Template::FAQ) and internals (Template::Internals) are all under construction.
