Release Notes: This version features a new meta-macro for formatting the current date and time.
Release Notes: A bug where #error and #warning directives were processed in the false branch of a conditional has been fixed.
Release Notes: GPP now features the commandline option --include, which allows preprocessing of a specified file before the main input file.
Release Notes: GPP now supports CPP-style #error and #warning macros.
Release Notes: The arithmetic evaluation macro (#eval) now supports POSIX-style wildcard matching (i.e., shell globbing). There is now an #elif macro to help avoid deeply-nested conditionals. Finally, a long-standing bug has been fixed where GPP would be off by one when reporting line numbers in its error messages or with the #line meta- macro.
Release Notes: This release features two new built-in macros, "file" and "line", with functionality similar to the C preprocessor's __FILE__ and __LINE__. It fixes a crash bug, and places the GPP manual under a free documentation license.
Release Notes: This release improves cross-platform compatibility, and fixes a bug which caused gpp to crash when the same macro was defined twice on the command line. It now issues a warning on the use of deprecated command-line options. Installation instructions were added for Windows, Unix, and other systems. It is now packaged in a manner similar to most GNU programs, including a "configure" configuration/installation script suitable for Unix-like systems. There are minor changes (mostly typographical) to the manual.
Release Notes: This is a dead and incompletely documented branch based on GPP 2.1 from the default branch. Most of the differences are internal changes to speed performance when processing particularly complicated macros. These changes will probably eventually be merged with the default branch. Unless you are using very tricky macros and are particularly concerned about execution speed, you would probably be better off with a release from the default branch.
Release Notes: This release has an XHTML mode, improved documentation, and miscellaneous code cleanup and bugfixes.
Release Notes: Fixes for various bugs and misfeatures of 2.0, and miscellaneous improvements to the general level of functionality of the GPP preprocessor. Some of the new features should facilitate integration into development environments.
