terminfo had a new release on hackage and we only ship the latest
version currently, so every GHC gets the newest version. Whether this is
correct, is another question, occurs to me – we'll have to look into
whether we should fix this at some point.
Since the overrides are practically the same for all but the latest GHC
version, we can move the override into configuration-common.nix and rely
on a few conditionals in the overlay assembly — and end up with less
copying around!
According to the Unicode Standard, you should use U+2019 RIGHT SINGLE
QUOTATION MARK for apostrophes [1]. Before this change, some of the text
in this repo would use U+2018 LEFT SINGLE QUOTATION MARKs instead.

Deprecate haskell.lib{,.compose}.generateOptparseApplicativeCompletion*
in favor of the newly added
haskell.packages.*.generateOptparseApplicativeCompletions (plural!)
which takes into account whether we are cross-compiling or not. If we
are, generating completions is disabled, since we can't execute software
built for a different platform.
The move is necessary, so we can receive the /same/ stdenv as the
package we are overriding in order to accurately check whether we can
execute produced binaries.
Resolves#174040.
Resolves#49648.
This is a dependency of cabal-install and builds by virtue of its
overrideScope. We also want to make sure it builds independently, so
that it doesn't get marked as broken at the very least.
GHC's cross build flavours disable the terminfo package, so it will
never be included if we are cross-compiling – setting it to null thus
breaks all builds depending on the package.
To fix this problem, we use the versioned attribute generated by
hackage2nix, just like we do for xhtml.
Closes#182785.
The xhtml library is only built as part of the GHC build process if GHC
is disabled. This means that no GHC cross compiler has xhtml bundled,
since haddock can't be built if GHC is a cross compiler (see relevant
notes in the GHC nix expressions). This means that all packages
depending on xhtml would currently fail to build when cross-compiled, as
haskellPackages would assume it'd be provided by GHC. This is fixed by
this commit.
pkgsStatic hits this case, so we test compilation of xhtml for these
package sets which will remind us to update the attribute name whenever
its version changes.
Luckily, all build failures where just related to type checking changes
in GHC 9.0 (and maybe base changes?), so we can just use GHC 8.10.7 with
the Stackage version of packages and keep Yi working. I feel like we
dodged a bullet here, as upstream maintenance doesn't seem to be too
proactive these days.
We need to manually simulate the following conditional in the cabal
file:
if impl(ghc >=9.0)
build-depends: ghc-prim
else
build-depends: hashable >=1.3.5.0 && <1.5
This means we only have to update the llvmPackages attribute in one
place now and should prevent situations like with 8.6.5 where different
versions would be used in the package set compared to the compiler
build.
Drop comments in the configuration-ghc-X.Y.x.nix files as well, since
LLVM version isn't tied to the compiler minor version at
all (e. g. 8.10.2 and 8.10.7 have different support ranges).
