ormolu 0.5.0.1 UNKNOWN UNKNOWN
using ghc-lib-parser 9.2.7.20230228
(I tested with ormolu v.0.3.1.0 which does not have this issue).

I believe it is 2023-08-05 (this commit). From this nix channel (updated an hour ago at time of writing).
What went wrong
Ormolu fixer doesn't format the file. The command history contains the following line (note exit code 9). See :ALEInfo section below for full output.
(finished - exit code 9) ['/run/current-system/sw/bin/bash', '-c', '''ormolu'' < ''/tmp/vKSqUsU/5/About.hs''']
Reproducing the bug
- Enable the
ormolufixer, open a Haskell source file which isn't formatted according toormolu's rules and save and trigger the formatting. - Observe that the source file wasn't formatted.

When running ormolu from the command line in the way it seems to be invoked from ale:
> bash -c ormolu < src/File.hs
The --stdin-input-file option is necessary when using input from stdin and accounting for .cabal files
Therefore, a workaround is to configure ormolu like this:
let g:ale_haskell_ormolu_options="--stdin-input-file ."
Perhaps this should be the default? The option is used here in the fourmolu fixer, which I believe is similar. If that sounds reasonable, let me know and I can give a go at a PR.
Hmm, if it indeed enough to fix the issue, I think you should very well send a PR :+1:
