GPP

GPP is a general-purpose preprocessor with customizable syntax, suitable for a wide range of preprocessing tasks. Its independence from any one programming language makes it much more versatile than the C preprocessor (cpp), while its syntax is lighter and more flexible than that of GNU m4. There are built-in macros for use with C/C++, LaTeX, HTML, XHTML, and Prolog files.

GPP is Free Software. It is distributed under the terms of the GNU Lesser General Public Licence.

Source code

You can download portable source packages for the current and previous releases on GitHub or nothingisreal.com. These include a portable installation script and installation instructions.

Alternatively, you can browse, download, or clone the development version on GitHub, though note that if you do this you will need to manually set up the build system using the GNU Autotools rather than using the end-user installation instructions mentioned above.

Ports and binary packages

Binary packages are available for several systems, including:

Note that these packages are produced and hosted by third parties. The GPP authors take no responsibility for them.

Documentation

You can browse through the online HTML documentation.

Note that the documentation itself is generated by GPP using an input file with macros that can automatically produce HTML, LaTeX, or troff (man page) output. Studying this file ( gpp.pp in the source) should prove instructive, and manually running it through GPP can serve as a basic test of the program's functionality.
