dev-haskell / fail

Forward-compatible MonadFail class

Official package sites : ·

This package contains the "Control.Monad.Fail" module providing the < MonadFail> class that became available in < base-> for older @base@ package versions. This package turns into an empty package when used with GHC versions which already provide the "Control.Monad.Fail" module to make way for GHC's own "Control.Monad.Fail" module.

*/*: destabilize dev-lang/ghc for all arches
dev-lang/ghc is a fast-moving target without much of stable API across major GHC releases. This makes stabilization process a fragile process. The change moves all haskell revdeps to pure ~arch. There are not many outside dev-haskell/*: - app-emulation/ganeti - app-text/pandoc - dev-util/bustle - dev-util/shellcheck - dev-vcs/darcs - x11-wm/xmonad/xmonad Existing stable haskell users are recommended to keyword used packages and all of dev-haskell/* to ease upgrades.

*/*: Inline mirror://hackage and update URIs
This change inlines mirror://hackage in all ebuilds, and updates URIs to the modern form (old URIs redirect to that). The change has been made using the following command: find -name '*.ebuild' -exec sed -r -i \ -e 's@mirror://hackage/@' \ -e 's@[^/]*)/([^/]*)/@\1-\2/@g' \ -e '/hackage\.haskell\.org/s@\$\{PN}-\$\{PV}@${P}@g' \ -e '/hackage\.haskell\.org/s@\$\{MY_PN}-\$\{PV}@${MY_P}@g' \ -e '/hackage\.haskell\.org/s@\$\{PN}-\$\{MY_PV}@${MY_P}@g' \ {} + Signed-off-by: Michał Górny <>
