Public bug reported:
ghc has fully deprecated and removed MonadFail proposal, requiring code
to be rewritten.
Git/Types.hs:144:14: error:
• Could not deduce (MonadFail m) arising from a use of ‘fail’
from the context: Monad m
bound by the type signature for:
textToSha :: forall (m :: * -> *). Monad m => Text -> m SHA
at Git/Types.hs:140:1-37
Possible fix:
add (MonadFail m) to the context of
the type signature for:
textToSha :: forall (m :: * -> *). Monad m => Text -> m SHA
• In the expression: fail "Invalid base16 encoding"
In a case alternative: _ -> fail "Invalid base16 encoding"
In the expression:
case B16.decode $ T.encodeUtf8 t of
(bs, "") -> return (SHA bs)
_ -> fail "Invalid base16 encoding"
|
144 | _ -> fail "Invalid base16 encoding"
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

100% ( 9 / 9) in 'Git.Tutorial'
haskell-gitlib still uses the deprecated "fail" which is no longer
exposed by MonadFail.
It is leaf without any reverse dependencies, please remove it from the archive.
