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

This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below).

[maintain] [Publish]

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.

Readme for cpphs-1.18

[back to package description]
This directory contains 'cpphs', a simplified but robust
re-implementation of cpp, the C pre-processor, in Haskell.

Just use
    hmake cpphs [-package base]
    ghc --make cpphs [-o cpphs]		#  -o needed for ghc <= 6.4.1 ]
    runhugs cpphs	# or rename the script cpphs.hugs to cpphs

	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
