I write Haskell program in Nova, but observe strange foreground color when LSP is enabled (see the screenshots).
The two screenshots are taken with the default Bright/Dark editor themes. You can find that the foreground color under the cursor is really strange. Only when I move the caret to a specific position (in the screenshot, it’s Ln 8, Col 22, after the “=>” symbol), the issue occurs.
In the screenshot, I use the “inspecting” tool to show the color and hope it can be helpful.
It seems that the issue is related with LSP. If I disable the LSP extension, the issue doesn’t occur.
Environment
- Nova 10.1
- macOS 13.0
- haskell-language-server-wrapper(haskell-language-server-wrapper) Version 1.8.0.0
- aarch64 ghc-9.4.2
How to reproduce
-
Install the
Haskell Tree Sitterextension from the extension library. -
Download the Haskell LSP extension and the sample project from here.
-
Setup the Haskell environment. You can install it through:
brew install haskell-stack brew install haskell-language-server -
After installing the extension, fill the config of the LSP extension like:
- Open the project
free-monadin Nova. To make the LSP work, you may need to clickExtensions -> Restart Haskell Language Servermultiple times due to this bug. Make sure that the LSP hover works like:
- Move the caret to “Ln 8, Col 22” of
app/Main.hs, delete the “=>” characters and type “=>” again you can observe the issue like:
