These optional dotfiles indicate the root of a module or module group (:lang), and will later contain module metadata. They will also serve as an alternative to packages.el and doctor.el, and will aide the parts of the v3.0 module API concerned with resolving the current module from a path (`doom-module-from-path`), which currently rely too heavily on parsing path strings. For now, however, they're simply placeholders. |

Hacks
No hacks documented for this module.
Installation
Enable this module in your doom! block.
It is recommended to install the haskell tooling using ghcup. Only ghc is needed for basic functionality:
ghcup install ghc
but +lsp users should also install the language server:
ghcup install hls
Installing cabal or stack as well is recommended, and can be done through
ghcup.
haskell-mode provides support for hoogle, which can be installed through
system package manager, cabal, or stack.
haskell-language-server provides support for hlint, and haskell code
formatters such as brittany, floskell, ormolu, fourmolu, and stylish-haskell,
which can be installed through system package manager, cabal, or stack.
Formatter
doom-module::editor format by default uses fourmolu to format code when not relying on hls, follow the linked install instructions.
