Hi, haddock-library is a package aiming to provide bits of Haddock to the rest of the Haskell world without imposing the GHC dependency that we have on the ‘haddock’ package itself. Please note that this does not deprecate the ‘haddock’ package which aims to expose other bits of Haddock, including those talking with GHC. Specifically, 1.0.0 exposes the types used by the comment parser and the parser itself. This allows you to supply the Haddock parser with String and get a Haddock ADT back out to play with. This means that if in the past you were processing Haddock strings with your own solution (or copy + pasted Alex parser we had) then you should now switch to this package instead. The API is subject to change so upper version bound is advised. Tested on 7.6.3, 7.8.x and current HEAD. The parser exposed is what is used in Haddock itself which now internally depends on this package. There are plans to move more parts into this package, exposing as much useful functionality as possible without the GHC dependency. New releases are independent of the GHC release cycle, unlike Haddock itself. To file issues for this package, use the Haddock issue tracker that's now on GitHub. Thanks -- Mateusz K.
