The Extended C Preprocessor is a preprocessor for C/C++ that is capable of adding operators, directly replacing text, and modifying syntax. It has a built-in uncommenter and C prettyprinter.

To read the "docs", head over to the wiki.

ECPP requires:

• GNU Make
• GCC

To build, run make, To build the uncommenter alone, run make uncomment. If you also want to individually use the prettyprinter, run make pretty.

To run ecpp with the uncommenter and prettyprinter, run out/ecpp sourcefile.

To run the uncommenter only, run out/uncomment sourcefile.

To run the prettyprinter only, run out/pretty < sourcefile.

To install on your system, run ./install /path/to/installation/directory. It will:

• Build ecpp, the prettyprinter, and the uncommenter (cleanly)
• Copy all the output executables to the specified installation directory
• Add the installation directory to the PATH environment variable
• Create a rule to add the installation directory to $PATH in the current user's .bashrc (or .bash_profile)
