A liberalised re-implementation of cpp, the C pre-processor.

Cpphs is a re-implementation of the C pre-processor that is both more compatible with Haskell, and itself written in Haskell so that it can be distributed with compilers.

This version of the C pre-processor is pretty-much feature-complete and compatible with traditional (K&R) pre-processors. Additional features include: a plain-text mode; an option to unlit literate code files; and an option to turn off macro-expansion.

cpphs

A liberalised re-implementation of cpp, the C pre-processor.

cpphs is a re-implementation of the C pre-processor that is both more compatible with Haskell, and itself written in Haskell so that it can be distributed with compilers.

This version of the C pre-processor is pretty-much feature-complete and compatible with traditional (K&R) pre-processors. Additional features include: a plain-text mode; an option to unlit literate code files; and an option to turn off macro-expansion.

Usage

cpphs  [filename | -Dsym | -Dsym=val | -Ipath]+  [-Ofile]
       [ --include=file ]*
       [ --nomacro | --noline | --nowarn | --strip | --strip-eol |
         --pragma | --text | --hashes | --layout | --unlit |
         --linepragma ]*
       [ --cpp compatopts ]

For fuller details, see docs/index.html.

If you want to use cpphs as a completely drop-in replacement for the real cpp, that is, to accept the same arguments, and have broadly the same behaviour in response to them, then use the --cpp compatibility option.
