Doesn't appear to recognise literate Haskell mode files. #119

Closed zac-garby closed 3 years ago

zac-garby commented 3 years ago

I've added these two lines to my .emacs:

(add-hook 'haskell-mode-hook #'lsp)
(add-hook 'haskell-literate-mode-hook #'lsp)

When I open a .hs file, the LSP opens up properly and everything works fine with the Haskell language server.

However, when I open a .lhs file, I get the following error message.

I've had a look through the settings for lsp-mode and lsp-haskell but I haven't found any fix for this, so I'm hoping this would be the right place to ask.

Thanks!

The strange thing is, it definitely should work, looking at the code for lsp-haskell,

    ;; Should run under haskell-mode and haskell-literate-mode. We need to list the
    ;; latter even though it's a derived mode of the former
    :major-modes '(haskell-mode haskell-literate-mode)

So I'm not sure what I might have done wrong.

EDIT: I may have found the problem? It seems that the literate Haskell mode in emacs is called literate-haskell-mode, but this package refers to it as haskell-literate-mode.
