Description
Describe the bug
Nix integration not working as expected in cabal 3.8.1.0.
To Reproduce
~/.cabal
❯ cabal user-config init
Writing default configuration to /home/amy/.cabal/config
~/.cabal
❯ cabal v2-update
Downloading the latest package list from hackage.haskell.org
Package list of hackage.haskell.org is up to date.
The index-state is set to 2022-09-04T17:19:43Z.
Now edit ~/.cabal/config, changing line 24 to:
nix: True
This used to work (e.g. in Cabal library and cabal-install version: 3.4.0.0), and it's what the documentation says to do.
~/.cabal
✦ ❯ cabal v2-update
Error: cabal: Error parsing config file /home/amy/.cabal/config:24:
True
Please use version-prefixed commands (e.g. v2-build or v1-build) to avoid ambiguity.
Expected behavior
cabal v2-update should handle this setting, or if something has changed and this is no longer correct, the docs should be updated and cabal should warn me.
