GPP is a general-purpose preprocessor with customizable syntax, suitable for a wide range of preprocessing tasks. Its independence from any programming language makes it much more versatile than cpp, while its syntax is lighter and more flexible than that of m4. The syntax is fully customizable, which makes it possible to process text files, HTML, or source code equally efficiently in a variety of languages.
Youhp3 (Youpee's One Unlimited HTML PreProcessor) is an HTML preprocessor that allows you to embed code of any script language, as well as calling any external program to generate text files. It is specifically designed to work with HTML/XML documents, and provide traditional features, such as define, include, macro, conditional tests, and loop.
EmPy is a system for embedding Python expressions and statements in template text. It takes an EmPy source file, processes it, and produces output. This is accomplished via expansions, which are special signals to the EmPy system and are set off by a special prefix (by default the at sign, '@'). It can expand arbitrary Python expressions and statements in this way, as well as a variety of special forms. Textual data not explicitly delimited in this way is sent unaffected to the output, allowing Python to be used in effect as a markup language. Also supported are callbacks via hooks, recording and playback via diversions, and dynamic, chainable filters. The system is highly configurable via command line options and embedded commands.
newfile generates "starting-out" files using a full featured template preprocessor. It can also generate trees of files, for example, a FreeBSD port or a project using automake and autoconf. A user can add their own template files and directories to those supplied with the package. It includes templates for making "empty" files for Ruby, make, shell, C, C++, C & C++ headers, and more.
rfc2mib is a short Tcl script which may be used to extract MIB (Management Information Base), PIB (Policy Information Base), and ASN.1 modules from an RFC document. Unlike most extractors, this script is smart enough to recognize ASN.1-style comments prior to or within the module header. It also recognizes the use of the "TagDefaults" part of the module header (not used by MIB modules), module headers that are broken across multiple lines, and macro definitions.
PXSL ("pixel") is a convenient shorthand for writing markup-heavy XML documents. It provides XML authors and programmers with a simple, concise syntax that they can use to create XML documents. For more advanced users, it offers customizable shortcuts and sophisticated refactoring tools like functional macros that can markedly reduce the size and complexity of markup-dense XML documents.
TclTP (pronounced "Tickle-Type") is a preprocessor based on the TCL scripting language. It allows embedding TCL command and and variable expansions in normal text. The result of expansion is inserted in the output. Quoting and escaping work in a similar way as in TCL, using braces and backslashes. A second stage of processing involves hooks defined by the document. This allows arbitrary transformations of processed text before it is written to the output. TclTP is primarily intended for generating complex static documents like Web pages. It is not a mark-up language per se. But you can define your own mark-up and use it in your documents, possibly allowing the production of output in different formats from the same source file.
lhs2TeX is a literate programming tool. It is implemented as a preprocessor that generates LaTeX code from literate Haskell sources. It allows for and provides different styles for the formatting of code. You can easily select between representing operators with mathematical symbols or with ASCII approximations, as well as deciding whether or not to highlight keywords. The formatting of your own defined tokens may be adjusted. Preprocessor-style conditionals are supported, and Haskell can be used to generate parts of the document.
Easy Generator Generator (EGG) is a development tool for fast and easy realization of XML to plain-text tranformations. It is similar to XSLT, Velocity, or JSP but emphasises source code generation in a model-driven generative developmen process. It comes with an iterative development process for creating templates that lets you build transformations quickly and easily.
