This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

notcpp is a library that attempts to provide an alternative to
using CPP as a mechanism for conditional compilation. It provides
facilities for determining if specific names or class instances
exist and responding accordingly.
When a value or class instance appears between minor releases of a
third-party package, a common way of dealing with the problem is to
use CPP to conditionally use one block of code or another. The
trouble with CPP is it's hard to statically analyse: tools based on
haskell-src-exts will outright refuse to parse it, for example. It
turns out Template Haskell will do the same job in some cases.
notcpp is largely a proof-of-concept, experimental package: you
are welcome to use it if it suits you, but it may be liable to
change suddenly.
