If it doesn't work, see the hie-bios manual to get it working. The ghcide executable mostly relies on hie-bios to do the difficult work of setting up your GHC environment. The failing files are all prototype work or test output, meaning I can confidently use Shake. Of the 158 files in Shake, as of this moment, 152 can be loaded by the IDE, but 6 can't (error messages for the reasons they can't be loaded are given earlier). For example, taking the example of shake, running ghcide gives some error messages and warnings before reporting at the end: Files that failed: Change to the project directory and run ghcide, which will try and load everything using the same code as the IDE, but in a way that's much easier to understand. Next, check that ghcide is capable of loading your code. It's important that ghcide is compiled with the same compiler you use to build your projects.

cabal install or stack install (and make sure ~/.local/bin is on your $PATH).

See ghcide-nix repository With Cabal or Stackįirst install the ghcide binary using stack or cabal, e.g. Remove redundant imports, replace suggested typos for values and module imports, fill type holes, insert missing type signatures, add suggested ghc extensions Ghcide already exports the following features via the lsp protocol: Featureĭisplay error messages (parse errors, typecheck errors, etc.) and enabled warnings. There are more details about our approach in this blog post. We provide a VS Code extension as extension in this directory, although the components work in other LSP editors too (see below for instructions using Emacs).

haskell-lsp for sending those messages to a Language Server Protocol (LSP) server.
