Check that GHC+HLS works together

[hasufell]

Check

• that the recommended GHC works with the recommended HLS
• that the latest GHC works with the latest HLS
• that the recommended GHC works with the latest HLS

[hasufell]

the first point seems done:

ghcup-metadata/.github/workflows/install-bindist.sh

Lines 75 to 95 in 9f595d9

	test_all_hls() {
	local bin
	local bin_noexe
	local bindir
	local hls
	bindir=$1
	for hls in "${bindir}/"haskell-language-server-* ; do
	bin=${hls##*/}
	bin_noexe=${bin/.exe/}
	if ! [[ "${bin_noexe}" =~ "haskell-language-server-wrapper" ]] && ! [[ "${bin_noexe}" =~ "~" ]] && ! [[ "${bin_noexe}" =~ ".shim" ]] ; then
	if ghcup_fun install ghc --set "${bin_noexe/haskell-language-server-/}" ; then
	"${hls}" typecheck "${test_module}" || fail "failed to typecheck with HLS for GHC ${bin_noexe/haskell-language-server-/}"
	else
	fail "GHCup failed to install GHC ${bin_noexe/haskell-language-server-/}"
	fi
	ghcup_fun rm ghc "${bin_noexe/haskell-language-server-/}"
	fi
	done
	ghcup_fun install ghc --set recommended
	"$bindir/haskell-language-server-wrapper${ext}" typecheck "${test_module}" || fail "failed to typecheck with HLS wrapper"

The second is to be done.

The third point is questionable.

Quick question

How is the second point supposed to be implemented?
Once GHC 9.12 is released, the latest HLS release will not support the latest GHC version. Or should this be understood as a checklist?

The third point seems sensible to me, isn't that also part of HLS's support policy?

I guess not really possible without delay.

If that is the case, then sure.

Maybe it is only part of it and not a strict requirement: https://github.com/haskell/haskell-language-server/blob/master/docs/support/ghc-version-support.md#extended-policy
