[Finding the locations of compiler errors after a change]
This is the typical use case for a language server. I have haskell-language-server installed and use it extensively on GHC for stuff like jump to definition and immediate compilation feedback.
There's also "jump to next error" if you want that.
I've now reached the stage where I make a change in a module, and it compiles, but the change causes a compiler error in another module far away. Is there a way to ask the language server to jump to an error in another module? (I'm using Emacs lsp-mode, and all I've found for errors is `flycheck-next-error`, which is not ideal. But if the language server can monitor the whole project, I'll get some Emacs help on how to get the info there.) Norman
