The ghc-lib-parser-ex package contains GHC API parse tree utilities. It works with or without ghc-lib-parser.
Using ghc-lib-parser-ex
Package ghc-lib-parser-ex is on Hackage e.g. cabal install ghc-lib-parser-ex. Like ghc-lib-parser, there are two release streams within the ghc-lib-parser-ex name.
Versioning policy
Package ghc-lib-parser-ex does not conform to the Haskell Package Versioning Policy. Version numbers are of the form α.β.γ.δ where α.β corresponds to a GHC series and γ.δ are the major and minor parts of the ghc-lib-ex-parser package release. Examples:
- Version 8.10.1.3 is compatible with any
ghc-lib-parser-8.10.*(orghc-8.10.*) package; - Version 0.20190204.2.0 is compatible with
ghc-lib-parser-0.20190204.
The major part γ of the release number indicates an interface breaking change from the previous release. The minor part δ indicates a non-interface breaking change from the previous release.
Building ghc-lib-parser-ex
Produce and test ghc-lib-parser-ex package distributions by executing the CI script:
# Setup
git clone [email protected]:shayne-fletcher/ghc-lib-parser-ex.git
cd ghc-lib-parser-ex
stack runhaskell --package extra --package optparse-applicative CI.hs
Run stack runhaskell --package extra --package optparse-applicative CI.hs -- --help for more options.
To run hlint on this repository, hlint --cpp-include cbits --cpp-define GHCLIB_API_XXX . (where XXX at this time is one of 808, 810, 900, 902, 904 or HEAD).
