'''Template and [macro] processing''' is perhaps more common in Tcl than many
[scripting language%|%scripting languages],  and many tools have been published.

** Macro/Substitution Tools **

   [expand], by [William Duquette]:   A dedicated T/M processor.  The core of expand was added to [tcllib]/[textutil].

   [Tmac - a Tcl macro processor package%|%Tmac], by [Roy Terry]:   a general-purpose [macro] package for expanding and substituting Tcl code.

   [Sugar], by [SS] :   a [Lisp]-like [macro] system for Tcl.

   [Subst template expansion helpers]:   

   [http://chiselapp.com/user/pspjuth/repository/tcl/home%|%Peter Spjuth's Chiselapp]:   includes "an experminent on compiled macros" with a very small core mod ([http://sourceforge.net/p/tcl/patches/535/%|%original patch submission @ sourceforge%|%]).  This is interesting for the very simplicity of the approach

   [knit], by [PYK]:   a [macro] system that leverages `[tailcall]`

   [cmacro]:   a C-preprocessor-like macro substitution mechanism for Tcl source code.

   [Percent Substitution]:   

   [tpp]:   A CPP-like preprocessor.

   [FrontLine], by [Koen Van Damme]:   the author has used Frontline to write a preprocessor based upon Tcl to get more power than provided by the [C]/C++ preprocessor.



** Template Tools **


   [TclHttpd], by [Brent Welch]:   a web server that includes a template processor

   [Kinetic Application Processor], by [AsiaInfo]:   a web server that includes a template processor

   [http://browsex.com/TML.html%|%Tml] a component of [BrowseX]:   a template processing system for both dynamic and static content.

   [Apache] [Rivet]:   the successor to [mod_dtcl].  `rivet::parse` can be used to create macros

   [mod_dtcl]:   

   [nstcl]:    the [OpenACS] templating system

   [scripted templates]:   where the template itself is a syntactically valid Tcl script

   [https://github.com/hartcw/smacro%|%smacro]:   A tool for programmatically generating embedded content within a file, similar to C/C++ preprocessor directives, except that the embedded code is expressed in Tcl.

   [teaspoon], by [xan]:   a PHP-like templating engine for Tcl, and works particularly well with tanzer

   [TemplaTcl]:   has just two tags, ASP-like, easily expandable, and relatively safe, as it runs in a safe interpreter.

   [tmpl_parser]:   

   [https://github.com/23/openliquid%|%Open Liquid]:   is a parsing and rendering engine for the Liquid Markup Language, written in C++ with the goal of being bindable to any scripting language interpreter. Currently, only Tcl is supported through the Tcl C API. 

   [TemplateRecall]:   

   [http://chiselapp.com/user/jdc/repository/tclTemplateToolkit2/home%|%tclTemplateToolkit2]:   A partial Tcl implementation of the http://template-toolkit.org/%|%TemplateToolkit%|%: 



** Description **

The cardinal rule for templating a Tcl [script] is that a value being
interpolated into a Tcl script as a word must be escaped as a [list] containing
that value as its lone word. This rule does not apply, of course, to the
interpolation script fragments.  See [Tcl Quoting] for further discussion.
