No handling of CPP in code

Reported by: nibro Owned by: nibro
Priority: minor Milestone: Blue Sky
Component: parser Version: 1.9.x
Keywords: Cc:


The hard part here is not to handle documents with CPP in them, we already use cpphs to un-literate code, it shouldn't be hard to run cpphs on it in full. But the question then is, is that really what we want to do? If we want to parse the source file, it would be interesting to be able to support all possible source trees that could result from application of CPP. That's a very different beast.

I nearly always have the line (stolen from HSE 0.4.8):

parseFileContents [if "#" `isPrefixOf` x then "" else x | x <- xs]

i.e. hide all lines beginning with a #. I find this allows a nice class of programs with basic CPP to be accepted, while being very easy to implement. Perhaps CPP should turn this tweak on, until some proper CPP handling can be performed.
