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 [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.
