MonoPatBinds prevents building with GHC 9.2 #23

Closed cdsmith closed 3 years ago

cdsmith commented 3 years ago

Even with cabal build --allow-newer, cabal will not build regex-tdfa using GHC 9.2. The reason is that it specifies -XNoMonoPatBinds as a default extension in the cabal file. This has had no effect since GHC 7.4, and has finally been removed in GHC 9.2.

I prepared PR #24 to fix this.

I can't test this at the moment as

I cannot install GHC 9.2 due to https://gitlab.haskell.org/ghc/ghc/-/issues/19734
Haskell CI does not test against HEAD: https://github.com/haskell-CI/haskell-ci/issues/460

@cdsmith: Would you mind testing this for me before I release it?

andreasabel commented 3 years ago

I released 1.3.1.1 on hackage.

andreasabel commented 3 years ago

I tested now with GHC 9.2 alpha2.
